Q: Is it possible to upgrade my HP 635 Notebook to a Dual Core ...

My notebook currently has a AMD E-300 APU w/ Radeon HD graphics 1.30 GHz. I've never done this before, so I have no experience in upgrading/installing a new processor.

A: Is it possible to upgrade my HP 635 Notebook to a Dual Core ...

Hi, It is not possible because the AMD E-300 processor is welded on the motherboard.

A:Xeon Dual Core 2.8GHz, can I easily upgrade to Dual Core 3.2GHz ?

Super Micro has no CPU support list that I could find for this board, nor in the manual. It may take a call or email to them to find out for sure.
I would be careful buying such used item from an eBay seller, check their return policies and reviews first.

Overall, from what little info I could find, it seems the 3,2GHz Xeons will work, but just a guess.

Hi, HP Elitebook 8470P is a series of many models/products of laptops and can spread over few years.

which model pentium 4 has socket LGA775 was implemented.
I mean which model brand hp or compaq or HCL or ibm ? year & model required.
I prefer to buy that model so that i can upgrade to latest processors.

Another question:
Will Pentium 4 with Socket LGA 775 supports any chipset model for upgradation to
1.Core 2 Duo
2.Dual core processors ?
If not pls give me the Chipset models support for the upgradation.

My plan is buy used pentium 4 LGA 775 & upgrade to new processor(only processor using same motherboard of the old one) which eliminates/reduces cost for upgradation.

Is this right plan or is there any complication in upgradation.

A:Pentium 4 lga775 upgrade to Dual core or Core 2 Duo

pathardware first please read this:

The list of processors using LGA 775 are listed on that page. As for your question, YES some P4 motherboards might support Dual Core and Core 2 Duo.

My Current motherboard is an ASUS P5B-MX/WiFi AP and I'm running a P4 Prescott on it. The CPU support list on the ASUS website lists Dual Core, Core 2 Duo and Quad Core support (With BIOS upgrade). My P4 actually was part of a Compaq system purchased way back in 2005. After that the rest of the system (barring monitor and processor) has had major overhauls.

But, as for your plan, I would suggest you go about building an entry level new system by yourself.

First, some keywords to help searchers:

QX9650, quad core, task manager, cpu-z, cpu-id, shows showing only 2 two cores.

I recently upgraded an Intel E8500 to a QX9650 and had the problem of Windows 7 only showing 2 of the 4 cores.

It took a few frustrating hours to find the solution, but I got there in the end without the need for a Windows re-install. I hope that this little post may help others to resolve the problem quicker than I.

1st: You must have Windows 7 Professional. Home Premium does not support more than 2 cores. Upgrade to Pro.

2nd: If Task manager and CPU-Z are only showing 2 cores, you'll be feeling pretty confused, right?

Go to Start-->Run, type MSCONFIG.
Under the BOOT tab, click 'Advanced Options'.
In the top left corner it says "Number of Processors" (you'll have been here already and it says '2').

Uncheck this and do a reboot.

This solved my hours of confusion. Now I have 4 cores in Task Manager, CPU-Z and all is well.

If all this fails, then get yourself set up for an OS reinstall; that should get you where you want to be.

I hope this helps folks a little as I had a hard time resolving this quickly.

I'm no expert but my sketchy understanding is that if you tell Windows you have no processors, it re-evaluates this at boot and discovers that you've changed from a 2 core to a 4 core.

Well, it worked for me and I hope it helps others out there.

Hi, I'm just about to upgrade my Mesh Matrix Premier (AMD Athlon? 64 3500+ with ASUS A8N-VM - Nforce 410 PCI-Express Mainboard) to a AMD Dual Core 64 4400 CPU.

Does the team think that Windows XP (SP3 installed) will cope with the change or should I plan to re-install XP?

And then! if I were to upgrade to Vista, would it be worth installing the 64 bit version?

or should I just burn my anorak?

A:Dual core upgrade

You probably can get away with a Windows XP repair. The current installation won't work as the memory map for the new board is not the same as the old one. A Windows XP repair will update the memor map accordingly. Also, it will update the chipset device drives too.

I am wanting to upgrade my current machine to a dual core Amd 6000+ and DDR2 Ram.
as the motherboard market is geared towards PCI-E these days I find myself needing to find a quality board that wont break me financially so that i might continue to use my AGP card.

I am not opposed to PCI-E but spent quite a bit on my 5950 ultra a couple of years back and it preforms remarkably well and i just cant bring myself to replace it.

would like to have a board with both EIDE and SATA controllers( I run Raid/0)
and supports at least 3 GB of DDR2 Ram.

I'm open to all suggestions and have presently only found a couple of ASrock boards with the specs I desire.I have no experience with ASrock products and am totally ignorant as to the quality of their products.

As it is probably apparent,cost is the issue here...I spent close to $500 US for that AGP card and I am stubborn and hard headed about wanting to replace it just to get superior performance from a dual core CPU.
Is DDR3 worth putting this upgrade off for?
Any advice would be greatly appreciated.

My thanks go out to all who read this

A:want to upgrade to dual core but want to keep my VGA card

Asrock boards aren't great. They're jointly manufactured by Asus (a quality brand) and Ecs (a not so quality brand). I think Asus just do the designing and Ecs do the rest. Personally i would go with pci-express. I know it's not what you want to hear but there really aren't too many boards supporting ddr-2 and agp. A few years is a long time for a vid card and while i'm sure it performs well agp boards are getting less and less available so for general upgradeability (which imo is always essential with computers) pci-express is the way to go.

Hi there. I was just wondering if I can upgrade my processor to dual core on my Dell Dimension 4600, if it's possible. Because I went to a certain computer site, and it said that dual-core celeron Cpu's do actually work with the Dimension 4600. I do not think that this is really true because it is a Pentium 4 based motherboard. Is it not? But I bought a Pentium 4 3.06 Ghz processor for my computer. Because the Pentium 4 Cpu now in it is only about 2.80 Ghz, with a 800 Fsb rate.

But the one that I am getting is the 3.06 Ghz with a 533 Fsb rate to it. Now I believe that this is the fastest Pentium 4 that there is available. Is that so? I was just checking. Because I wanted to upgrade my Cpu, and take out the old one, and put in the new Cpu when it comes. I wanted to order a newer Cpu because I want to record VHS tapes to my computer. And for this, I have gotten a T.V. tuner card along with a Nvidia 128 MB graphics card. But that article that I read online said that my Dimension 4600 can take dual-core celeron Cpu's.

And also, it said even that it takes quad-core Cpu's too. But for this, I would probably have to buy a new motherboard for this, and take out my old one in my computer, and put the new one in, if that is even possible. Is it even? So just explain to me on what types of motherboards are compatible with my Dell Dimension 4600? Just let me know here. I saw some photos online of someone else have a Dimension 4600. And they upgraded the motherboard... Read more

A:I would like to know if I can upgrade my Cpu to a dual core Celeron

To update your CPU you will need to install a new Motherboard, and this new motherboard will require different RAM then the sticks you have. And your Power Supply Unit will need to be upgraded to work with the new motherboard. Other then the HDD and the CD drives, in essence, you need to buy a whole new computer. You can better spend your money on a New/Used computer from Ebay or Craigslist.

What I have:
Acer Aspire SA80

Socket vga775
Celeron D in it

I was wondering if I could swap that for an intel dual core also having socket 775.

If the answer is no, I'd appreciate the explaination, would it be because of specs being too low on the mobo? Which specs? I finally found specs for the mobo on the ecs site, only says stuff about "up to" whatever GhZ.

I wouldn't wanna have to buy a new mobo to use a dual core..

Any help would be amazing : )

A:Upgrade to a dual core, socket 775

You wouldn't be able to run the latest Core2Duos.

The motherboard doesn't have enough power phases to deal with them.

For true confirmation, why not call Acer and see what's the most powerful CPU you can pop in there?

It depends on the chipset used in the motherboard, power requirements of the new cpu and the old motherboard's ability to provide that power, and if the BIOS has any limitations added by the manufacture that may supersede the chipset design.

I read many posts about the opportunity to upgrade an Optiplex GX620 from a Pentium 4 to a pentium D. upgrading up to a D 930 or a D 960 seems good (according to the feedbacks).
Intel developed a lot of Dual Core processors. For example Pentium E 5500
When we look at the specs we can see that the socket is the same (LGA 775), and the FSB (800 mhz required) also. The voltage of the E5500 seems to match with the voltage of the D or 4 . I understand that E5500 has a smaller TDP (65 W) than a pentium D and should not give problem with heat..
My question is : can we upgrade an optiplex GX 620 from a Pentium 4 to a pentium E 5500 ? and, if it is, does it worth it?

A:Optiplex GX620 upgrade to dual core

Short Answer NO you cannot.
The E5500 will not work in the 620.
Bios MUST BE UPDATED Before changing CPU.

I am torn between buying one of two Acer laptops. Both have almost identical features--RAM, HD, webcam, 6-cell battery, memory card reader, and are the same price--$499.00 (on sale); but the processors seem to be the big difference, and I would like to know which one you folks feel I should go with.

I should also mention that the AMD laptop also has a Blue-Ray Disc drive (and read/writes normal CDs and DVDs).

The only other major difference when comparing specs is that the AMD laptop has an HD CineCrystal LED-backlit TFT widescreen display, ATI Radeon HD 4250 graphics with 256MB of dedicated system memory, supporting Unified Video Decoder 2 (UVD2), OpenEXR High Dynamic-Range (HDR) technology, Shader Model 4.0, Microsoft DirectX 10.1
.........While the Pentium laptop has CineCrystal LED-backlit display, Intel HD graphics with 128 MB of dedicated system memory, supporting Microsoft DirectX 10.

I've been driving myself crazy for the past 3 days trying to decide which one to go with and I need to decide quickly as I'm not sure how long they will be at this sale price--and I do have to stay at the $500.00 range. From the many laptops I checked out, these 2 seem to offer the most for the money. I would truly appreciate your advice!


A:AMD Turion X2 dual-core P520 2.3 GHz or Intel Pentium Dual-Core P6100 2.0 GHz?


I'm sorry to bother you folks again, but I noticed that my question had 55 views but no replies. Did I perhaps give incorrect or confusing information, or maybe posted my question in the wrong forum? I tried looking at some of the other similar questions asked, but none seemed to help with my question.

I guess I'm basically wondering that since the 2 Acer laptops are the same price, would you go with the Intel Pentium Dual-Core P6100, 2.0GHz, 3MB L3 cache, or the AMD Turion X2 dual-core P520, 2.3 GHz, 1066MHz Front Side Bus, 2MB L2 cache. This laptop also has a Blu-Ray Disc Drive, but I've read conflicting opinions on whether having this is necessary or not.

Although I consider myself to be an intermediate computer user, I am lost when it comes to processors, and also when it comes to 'dedicated amount of system memory.' I know that 'dedicated' memory is better, but does it make a difference how much there is in different brands? In other words, could the lesser amount of 128MB 'dedicated' in the Pentium still be better than the 256MB in the AMD? I'm leaning toward the AMD Turion laptop because of the higher numbers, but I've read enough to know that you can't always rely on that alone.

I'm sorry to ask my question again, but I've been given a lot of help here at CNET in the past, so I was surprised when I logged on today to see that no one expressed an opinion on which one of the two the... Read more

AMD Athlon Dual-Core QL-67 (2.2GHz, HyperTransport? 3: up to 4.0 (GT/sec), 2MB L2 Cache)

Intel® Pentium® processor T4300 (2.1GHz, 800MHz FSB, 1MB L2 Cache)
thank you

A:Comparing amd athlon dual core and intel pentium dual core

They are quite similar. Both have nearly the same clock speed. Both have a total of 1MB of L2cache but the intel's is shared and the AMD's is exclusive. The intel is 45nm and the AMD is 65nm which means the AMD will run hotter most likely. The AMD gets a boost from its on die memory controller and HyperTransport links on its motherboard. Both are capable of running full 64 operating systems.

The best difference between them would be as to what is on board their respective laptop. The AMD will have quite respectable performance from its video chip as I would hope it either a Radeon HD 3200 or better a 4200 with SidePort memory. These are about the best you can get for integrated video these days. The intel will undoubtedly have a GMA4500. These don't game very well nor do they do a very good job of playing high def video. The AMD chipset should have a fairly complete selection of connectors and functions. The interl may or may not, depending on the maker.

Both chips have a TDP of 35 Watts. The intel should offer slightly longer battery life for a given series of tasks, say about a half hour.

As you can see, these two CPUs are quite similar on and of themselves, the supporting cast of laptop parts makes or breaks the deal.

Hi i have a similar story to this thread HERE

Basically i was running this

I saw THIS on ebay and brought it.

I swapped over the MB,pro and Ram from this into my previous spec system, as this is the main PC in the house and in the aerocool case and i have a 600 watt power suply.
I Didn't swap HD.
So i put the amd sck 939 specs into the EBAY case. Installed windows with no problems

I turned the newly updated dual core PC and went through all the hardware changes with no problems. Everything seemed abit faster but occasionally the PC would freeze for 4-5 secs but you can still hear the HD hard at work.
I then went to play my favourite game CoD2 online but to my surprise finding it slow and choppy even after the game detected the hardware changes.I googled and found THIS
tried the optimizer and amd driver but no difference.I thought maybe because i didn't format. So i formatted, reinstalled windows, updated windows, installed all drivers from disk.Tried my CoD2 game, still slow.
I have tried updating bios, MB, graphics card drivers. I have reinstalled the AMD optimizer and processor driver.
I still get the freezing of the PC, especially if i minimize a game.when my PC boots up and i click my computer the flashlight comes up for about 20secs before it finds anything.

Hi guys. I've been looking at 2 laptops, they are basically identical but one has an Intel Core i3-4005U mobile processor and 4GB of RAM, and the other one has an AMD A4-5000 mobile processor and 6GB RAM. The guy at the store and a couple other people I know told me that the Core i3 is better than the A4 as the AMD "Quad Core" processors aren't very good, so even though the Intel i3 is only dual core it will be better than the quad core AMD. The other question is the RAM. Is 6GB that much better than 4GB or will 4GB be fine for basic use. (That's all this laptop is for. Basic use and touch apps since it will be touchscreen)

The AMD laptop is this one: Buy the HP Pavilion Notebook - AMD A4, 6GB, 15.6 at
And the Intel here: Buy the HP TouchSmart 15.6 Notebook PC - F5W37UA#ABL at

Last question, what the hell is DDR3L? All the new laptops have it nowadays... Is it backward compatible with normal DDR3 laptop RAM? Meaning can I take a normal laptop DDR3 4GB stick out of my dads laptop and put it into the 4GB (i3) laptop if thats the one i'm gonna get? Or does the DDR3 "L" part cause issues?

Hmm, I guess you should read some reviews. But just from the specs the AMD has 6 GB ram instead of 4. Has a DVD burner where the Intel shows no optical drive. It only has W8 8.0 where the Intel has 8.1. But some people may prefer 8.0.

Read reviews. See how each performs. If you don't wish to use it to burn DVD then the optical drive, or lack thereof may not matter to you.

Edit: Oh, and the AMD is about $80 cheaper.

I don't know if this question has been answered here or not because the words are a little difficult to do specific searches for. I am thinking of making for myself a file server. It's going to be cheap because it's main purpose is the processing of files from a centralized location. As such, I know I want processing power; but, I know I don't need a Core. As such, I'm sticking with a Pentium. I got the choice narrowed down to a Pentium Dual-Core. But, as I was researching the Pentium, I found out that the Dual-Core was re-branded to just a Pentium with dual-core features. My main question is is there a difference between the Pentium Dual-Core and the Pentium with dual-core features? I'm choosing between an ASUS P5G41C-M LX and a P5KPL-AM EPU.

Hi, Currently I'm using a dual core 6850 and I'm thinking about buying a quad core. I have a PSU of 500 W as spare.

Can i replace the CPU to a Quad Core without changing the cooling system?

A:replace dual core CPU by quad core what about heatsink? in Mini Tower 755 Optiplex

These are the specs of the spare PSU. Aren't they better than the original Dell PSU?
That power supply is ATX and not EPS12V
Better is not the issue.  Dell power supplys are 80 percent efficient not 70 percent ATX.  The -5v rail is an issue as well as this may cause a motherboard fire or damage your system.  Its a dead giveaway that this is a power supply from 1990 to 2000.
What current is on which rails is not trivial. There is a single 12V RAIL on that unit and its max is 17A
EPS 12V units have multiple rails of 12V @ 18 amps each.  MAX Power on the 12V rails is 264w not 204w
That unit has a lot more on the 5V and 3.3V rails at the expense of the 12V rails and CPU 4 pin connector. So no that spare unit is not likely to work well if at all.

I'm buying a new computer with Vista home premium (32 bit), and I can't decide whether I should get a 2.4 quad core or a faster dual core (since it's cheaper).

I've searched about this but all the results I've got were from 2007, so I'm not sure if things changed much now.

So what do you think? will I benefit from the additional cores? or shall I go with faster dual cores?
appreciate your help

Hello friends,
I m very eager to know that whats the actual difference between a Core 2 Duo processor and a Pentium Dual Core processor, other than their proceesing architecture?

According to most benchmarking sites including Tom's Hardware, Core 2 Duo E4300 or 6300 performs better than Pentium Dual Core 820 in almost all benchmarks.....whereas C2D E4300 or E6300(1.8 and 1.86 Ghz respectievely) are having MUCH lower clock speeds than Pentium D 820(2.8Ghz). Why like this???

I have 2 systems, one with C2D E4300 1.86 Ghz and another(from which I am writing this thread) is Pentium D 820 2.8Ghz. But I dont see any MUCH performance difference in reality, although in multi-tasking and gaming C2D system still performs better.

Can anybody please explain me in details.....
Thanks in advance.

A:Why Core 2 Duo outperforms Pentium Dual Core even when C2D has lower clock Speed??

The Core 2 Duo doesn't share the same architecture as the older NetBurst architecture of the Pentium D, which is also shared by the Pentium 4. The Pentium D is effectively a pair of Pentium 4 CPUs on one die. The Core 2 Duo architecture allows for a lot more processing to be done in one cycle, hence more information can be pushed in, say, 1 million cycles by the Core 2 Duo than the Pentium D. As for 'reality', there obviously won't be much difference when both systems are used for stuff like playing music etc. But the real differences will show up when you tax them, such as when playing an HD video without a video card supporting HD-decoding where the Core 2 Duo will be able to process information much more quicker than the Pentium D and so you will have a smoother image. Check on Wikipedia for more in-depth details.

I have two laptops made by the same manufacturer and same year, but one is a dual core laptop with an SSD harddrive and the other is a quad core laptop with a regular hard drive. Both laptops run Windows 8.

I would like to transfer my programs and files from the dual core to the quad core. However, obviously the quad core has different hardware.

I am wondering if I simply remove the SSD from the dual core and put it into the quad core (replacing the quad's primary hard drive with the SSD) and simply boot up the quad core, would that be sufficient? Will the quad core recognize the hardware mismatch and automatically correct the drivers, while keeping my programs and files?

Or is there some other, efficient way to make the transfer? I really want to avoid having to reinstall all my programs.

Thank you

A:Core 2 duo, dual core, and Athlon64 X2 Dual Core

No. It simply means you have more than 1 CPU on the die. A 4 core 2.0 CPU means you have four (4) 2.0ghz cores on the die.

At this point, just because a GHz is faster doesn't mean the system or the die is faster or slower than others. There are many things now that affect speed - ram (or lack thereof), the efficiency of the programs to multi-task, HD rpm, chipsets, and others. The trend to faster GHz CPUs with single cores ended a couple of years ago as CPU makers discovered they ran into a thermal barriers with smaller circuitry that they couldn't get around. So they decicded it would be better to put more than one CPU on the die. Thus we got multi core CPUs. Yes- even here they are trying to make each core faster, but there is still a thermal barrier.

For the most part, you really won't notice much of a difference in speed after a certain point. - You have to take the whole system together. Gamers need to pay special close attention to their graphics cards and RAM.

Today I took my Athlon 64 3200+ and replaced it with a dual core 3800+ (this is a socket 939 system). Everything went smoothly, system powered up, and cpu temperature is at 33c. My BIOS (which the latest and last for my mobo) is for dual core.

I logged on to the internet and at first no issues for about 3 minutes but then I noticed I couldn't access sites. It was like my internet connection just froze. Figuring it was one of those occasional needs to reset the router/modem I reset both by unplugging the power for 10 sec.

Nothing changed even after reset. I figured it was a dual core thing and so I installed the Windows hotfix for XP and dual cores. I also installed the AMD Dual Core Optimizer.

When I rebooted I was able to log on to the internet but accessing or even my mail is either really slow or froze. When I tried to log on here loading time was agonizingly slow to the point I had to disable the firewall in order to log on.

I have changed nothing with my system other than the CPU. I am at a loss. Could the firewall be the issue by the fact my hardware has changed? I doubt it but as I said I am at a loss. Thanks in advance.

A:What is better for PC gaming Dual Core or Quad Core?

It's a little confusing. I'd say in general, quad-core processors are more powerful than dual core; however, that doesn't necessarily mean faster.

Certain programs are written to take advantage of multi-core processors, like many games and power-hungry programs such as Photoshop.

However, not all are. Windows does its best to distribute the load evenly, but it's not the same.

Furthermore, many quad core processors are clocked at a lower rate than dual core. Your dual-core processor is clocked at 3.23GHz; the quad is clocked at 2.66.

Bottom line: if the programs you will be running can make use of all the cores, you will very likely see a performance increase. If they are not designed that way, there is a good chance your performance will actually decrease.

In your case, I suspect the programs you will be running can make use of the 4 cores well; many games do. But use your judgment!

Can be noticeable, but you need to include the power supply, cooling fans and other issues into the mix. There are good full reviews on Toms Hardware and Anandtech that give you a good picture of how they compare.

I was looking around at processors today, and i found a AMD Athlon 64 4000+ for $xx. There is a AMD Athlon 64 X2 3800+ for just a little more. Which is better and why? Also i'm debating between amd or intel. if i go intel i will go Core 2 Duo, but they are a little pricey. Right now what is the advantage (for gaming) of dual core. Is a really fast single core good for gaming? i know dual core is good for multitasking, and all i multitask now is i run a webcam server and have to shut it down to play game on a single core. I know this would help but it's not that important. So... all you smart techie people who know more about processors than me, what would you suggest:
Athlon 64 4000+ single 2.4ghz
Athlon 64 X2 3800+ dual 2.0ghz
Pentium D Single 3.0ghz
Pentium Core 2 Duo Dual 1.86

Hey I am confused by the terminologies Dual Core and Core 2 Duo, can someone please tell me something (not so technical) about the two CPUs? Some sales person in a PC shop told me that Core 2 Duo has chips? cores while a dual core has 2 chips? Is this informations right? Someone please reply as I am planning to upgrade from my ancient Pentium 4 machine to a new one and would like to get as much bang for my cash. Thanks.

A:Confused - Dual Core and Core 2 Duo

From what I can make out they are both the same. Intel set out to confuse everyone by the Core 2 Duo thing while AMD just called it dual core. I have 2 computers. One running Core2Duo and the other an AMD dual core. A diagnostics program refers to each as having 2 CPU's

I found a post by a user that claimed True 2 CPU systems we far superior to Core2 Duo systems.

This meaning that you run 2 processors on a Mobo each with a single core as compared to a mobo that supports 1 cpu unit with 2 cores.

I beleive the he could be right regarding this with the early dual core cpu unit technology. But is this still true?

What is the efficiency comparison between these 2 systems?

Lets say running 2 single core 1.5ghz compared to a single unit with 2cores each at 1.5ghz.
Keeping in mind that cache, bus speeds, architecture, brand etc would be the same in this hypothetical Question.

Is it worth looking into a mobo that is for dual quad core compatible?
meaning a mobo that supports 2 q6600 quad cores for example?

Do programs and games actually have the coding written into them to fully utilize this kind of setup to its max?

most of the articles and threads i find regarding this are pretty old and i am wondering how things look in the present day.

Is fine grain threading compared to multi threading simultaneous multi threading etc programming coding widespread now? or at least widespread enough in gaming etc to make it considerable when buying hardware or building a new system?

It will probably be OK but if the replacement CPU is a higher wattage keep a carefull watch on the temperatures. Make sure you apply new thermal paste when fitting it. Use this free software to watch the temperatures, set it up so it displays the temps in the task bar.

I have installed windows 8 x64 consumer preview. Under the task manager performance, Im only seeing one cpu graph, and it reports one physical processor and two `logical` processors.

Also under device manager, when I get the properties for `Computer` it says acpi x64 based pc, I think older windows already reported multi processor unless the wrong HAL was installed.

In device manager under processors, properties shows to separate entries of amd 550.

My concern is if the wrong HAL was installed.

Basically i'm not a computer expert I know the basic/intermediate knowledge of a computer and would like some tips. Im into my gaming, not very competitive gaming so none of the popular CoD games and such but games such as WoW, WarRock, RisingForceOnline and such others but I came across a dilemma. What would be better for gaming, a quad core processor, or a dual core processor. The processor's I speak of are the

AMD ATHLON II X4 635 AM3 Quad Core Processor 4 x 2.9Ghz

And the

AMD Athlon II X2 Dual Core 255 3.10GHz

I'm a bit unsure of how this all works out because the quad core has 4 x 2.9Ghz processors therfore a total of 11.6Ghz, and the Dual core would equal 6.2Ghz. Could some explain to me how all of this works and which would be better for my situation?



A:Quad core vs Dual core

First, the quad-core has 4 2.9GHz processors equal to 4 2.9GHz processors. They are not accumulative. Don't mistake this.

The average Windows program is written for one processor. That program will use one processor, regardless of how many you have in your system. Windows is not like Linux. The operating system doesn't control processor use, the individual programs do.

WoW has been optimized for use with multiple processors. But it hasn't been written from the ground up to support them.

In WoW's case, you will see better performance on the dual-core listed than the quad-core, provided you are not doing anything else on the computer at the time.

In short, multiple processors optimize using multiple programs (that actually use the processor in the first place). They don't optimize the speed of a single process. Don't add up processors for speed. It doesn't work that way.

A:dual core vs single core

Hello kf10,

CPU Frequency is often perceived as the (only) factor in cpu comparison, this is naive and wrong. Megahertz myth - Wikipedia, the free encyclopedia
We can't tell right away without seeing the detailed specifications of each, as there are more factors affecting the overall quality of a CPU, aside from the number of cores and the CPU Frequency. If both are Intel CPUs, you can have a detailed side-by-side comparison here.

dual core 1.8, or single core 3.6?
i have 3.6ghz but i was wondering which is better? i understand that dual core is more efficient and can multi task. but if i was playing farcry 3 which is really heavy on the cpu, and the ram and gpu wasnt effecting the performance, then which would be better? i think 3.6 because farcry would be the only programme running. and even though the dual core has two cpus, would it be able to share the load between them? or does it have a limit of 1.8.

So, is dual core better for running lot of little tasks, and a single core better for running tougher tasks?
any other information regarding cpu speeds will be appreciated.

I wouldn't say I am an extreme multitasker, but for an extra $10 I can upgrade to a third core. I was gonna order a new PC from a website and from what I thought, each core was combined to make a total speed. So a dual core 2.8ghz would be two 1.4ghz cores, and a triple core 2.8ghz would be three 0.9ghz cores?

I am most likely confused, but that's why I can here. XD

No there will not be any conflict. If the motherboard has a BIOS that supports dual-core processsors, it will use both cores present on each processor.

I'm wondering if it is possible or pratical to upgrade the Core i5 processor processor in my Inspiron 17R 7720 to a Core i7? The processor in my computer is a Core i5 [email protected] 2.5GHz; I am seeing multiple Core i7 3630QM SR0UX processors on Ebay for $100 or so. I am not worried about the mechanics of changing the processor, I am confident in my ability to swap one out. I just want to make sure the new processor will fit and work with my existing motherboard. If I do this will the BIOS automatically detect the new processor or are there some software hoops to jump through as well?

A:Upgrade Core i5 to Core i7 in Inspiron 17R 7720?

While the CPU will work, you won't see $100 worth of performance boost from the CPU -- if the system is running  a conventional hard drive, the $100 spent on a solid state drive to replace it will be far more bang for the buck.

I just registered on this board, after learning a bit about dual channel memory from posts here. Didn't learn enough though...

First off, thanks for the scoop on why dual channel doesn't work with Athlon XP. I once had it in an ASUS board that was supposed to run dual channel. I could not tell the difference in performance when it booted up in dual channel mode vs single channel. (The BIOS displayed which it thought it was running on boot-up.)

I am now building up a system with a Pentium D (805) in a ECS P4M800Pro-M mobo. This is claimed to support Dual Core operation.

A couple of general questions...

1) Regarding Dual Core and Dual Channel Memory operation, are they totally independent...? Will both features work together, or can you just get one or the other (or neither) on this combo...? I see NO mention of dual channel memory in the mobo manual.

2) I plan to run Win 2000 on this machine. Does that support Dual core, Dual Channel, or both. Or are these modes totally independent of the operating system software...?

3) My understanding of Dual Core operation is minimal. I guess it means you could have one core running MS Word while the other runs MS Excel, or plays a game... Is this correct? If so, is the operator in any way aware of the machine operating in this mode, or have to do anything to make it operate in the dual core mode? Or is the operator totally unaware of the dual core operation, except for, hopefully, bet... Read more

Faster memory will work at a slwer speed, you can use both at the same time, and I think your Mobo supports Dual-Channel, but im not sure. You will notice the differance either way with more memory.

Anyway the main question i want to ask is shall i just build a pc with one amd 64 x2 2200 (dual core) or fit two amd athlon xp 4400 processors.

I been doing some research on the net n some people say that the dual core performs faster than dual processors (
n people from other forums say that dual processors r better so i am really confused atm

when i start to build my pc i will prob go for 2 dual processors (like the powermac quad processor) since i kno that will be btter than two athlon xp 4400 processors unless this is not a good idea then dont be afraid to tell me why

My Dell Inspiron E1505 has an Intel 1.66 Ghz/2 Mb/667 Mhz (T1300) solo core CPU. Last week my computer stopped booting (you can read my post about it under Mobile Computing) and I believe the problem is either the CPU or MoBo. I may end up replacing both. So my question is do I need to replace the CPU with a solo core with same specs or can I upgrade to a dual core CPU? It seems that it is not that easy locating an Intel CPU with same specs and solo core. Also, can I up my processor and/or bus speed and if so will a higher CFM fan be needed? Would it be better to try a new CPU and then MoBo (if CPU is not the problem), MoBo and then CPU, or just purchase a new MoBo with CPU included?

A:Replacing a "solo" core with dual core?

What version of Windows are you running? If you are using Windows XP, be advised that most likely you have a single-CPU kernel installed, and that while it will *work* with a dual-core CPU, it will not give you access to both cores. You'll need to replace the kernel or do a repair/reinstall to get access to both.

I am not sure if this is true for Windows Vista.

Also note that you'll probably want to call Dell and find out what CPUs your motherboard supports.
