You CAN access each individual core. Open task manager and assign whichever core you want to a specific process... I honestly fail to understand why you guys think it is impossible. If this has been programmed into XP Pro for at least since the last service pack, how long has it been possible??? If you can adjust individual programs with the task manager, then software obviously CAN take advantage of the individual cores...

It actually treats the cores like individual CPUs. You can even see this on an Intel processor with Hyper Threading. Open Task Manager, click the processes tab, right-click on a process, and click set affinity... Each core, (virtual, separate CPU, or individual core on a dual core), is treated as if it was a different CPU. It's thread management, no matter the hardware.

Ya, my mom's PC has a P4 540 3.2Ghz HT and its got the two seperate graphs for each "cpu" although theres only one.

I didnt know that you can assign them like that to a certain core.

Ya its only one core and one cpu, but i mean how it shows up as 2 cpus in Taskman.

I'v been following this discussion for a while. Soooooo if I am a hardcore gamer should my choice 4200+ or 4000+? PCGEEK showed links to all kinds of updates to make ur dual core get better fps, but i didn't seen any benchmarks :( unfortunately which would show all updates in action with the dual cores. As far as my budget, I can get either the 4000+ or 4200+ (4400+ doesnt worth the extra money). So far I am thinking gettin a dual core is the right choice because right it might run a few frames less than the 4000+ but later on, with dualcore designed games as well as windows vista, it will pay itself off? I am right? So I should definately go for the 4200+ ?

lol don't be lazy man click on my web site all benchmarks are always there.

As for what duel core to get . Raw speed will play the biggest part in FPS. Any duel core will work. Just overclock it as high as she will go. Cache will have little to no effect on FPS.

The windows shell and functions passed on to software are two completely separate beasts. Also, I doubt the processor observes that function of the OS. That function is probably in place for dual CPU systems which, XP Pro is designed to handle as well.

As I said before, those are all monitors with read only attributes. The task manager always has displayed core usage. The more cores (virtual or physical), the more displays. It's also easier for Microsoft to display the information in this way so they don't need to add a CPU average score as well.


I say go with the 4200+ X2. The 4000+ will get better FPS in games but otherwise, the 4200+ X2 will perform better. Gaming is only like 1% of what computers do so don't make your decision based solely on that.

If all you do is gaming, base your decision on what will be best for gaming...

If all you do is word documents, base your computer on that..

I got my computer for gaming and I got this because of it...I am extremely happy with it. I honestly believe that you can program to access individual cores in games, but who cares? Get the computer you want. There will be different opinions and ultimately all that matters is the research you do yourself, we can only guide you. Obviously GT90 believes you should get the 4000+ for gaming. I agree, that is a great core and it plays any game nearly flawlessly. I would reccommend the 4400+ because that is what I have and its working great for me. PCGEEK would reccommend the 3800+ and for you to overclock it and get some downloads.

It is up to you and what you want to do man. But to be honest, the processors that you are looking at all kick some serious ass and you are gonna really like your new gaming system no matter what you decide on purchasing..

Good luck,
-Will

O hell no. i got 3800 kuz its all that was avalible to me. I also knew i could get 5000+ to 5100+ speeds out of it. If i could i would have got the 4400+ so i could get 5200+ to 5400+ out of her.

Oh sweet...What sort of speeds do you think you could get out of the 4800+?

Average i see is 5600+ but shes not cheap CPU bro. lot of money to be overclocking.

ya probably better deal would be the 4400 CPU instead of the 4800.

4400+ $500 newegg.

4800+ $800 newegg

3800+ $325 Newegg

4400+ = 5200+ on air

4800+ = 5600+ on air

3800+ however overclocks a bit different 5100+ on air

My choice price/ performance 3800+

my choice if money isnt as important 4800+ all the way.

well i can switch down to a opteron 165 and it will spank the 3800 even when overclocked.

"As I said before, those are all monitors with read only attributes."

Wrong. You can change which core or processor is assigned to a process with Task Manager. You are saying how you THINK it works. I'm telling you how I KNOW it works. In a similar way, you can run 2 instances of Prime 95 and set 1 program to 1 core and the other program to the other core. This is common knowledge and a good way to test for stability in both cores. :) No matter if it's 2 CPU's or 2 cores in a single CPU, drivers have to direct traffic. Acting as a navigational instrument is not affected by the location of the destination. It's simply a "go this way or that" type of situation. Traveling across the motherboard or across the die really doesn't make a difference other than the increased latency across the motherboard.

Hi all , been reading a lot on this site ....as I always say knowlege=power !
anyway , I used to have an AMD3000+ 754socket , was ok ...but time to upgrade
it used to run at 40 - 50'celcius , so I don't think I can o'clk much ....
I play games , but not intensively, use it more for chess programs , DvD burning , ripping , copying files
and so I am looking at the x2 4400 since it has 1mb for each core and I am hoping this will improve on
the above tasks ...? as compared to the cheaper x2 4200 which has 512kb on each core.
since both chips run at 2,2ghz the question of extra cache vs price for wot I need my pc for...which is better?
btw still deciding on the 4000+ with 1mb cache , but I don't think it'll handle the multi-tasking as well as the x2 's..

The extra cache only really comes out to shine in 64-bit applications, otherwise, it can actually afford a slight performance hit.


Blue, is there anyway you can even prove that it did move the task? If you had Prime95 running on one core, it would imbalance the two core loads (one at 100% and the other 5-10%). Now, since the processor itself handles load distribution, even if you told it to change cores, it won't because it doesn't have control over that. Now, on a dual CPU system, it can control which software goes to which CPU because that decision is made on the software level, not the hardware level. Since the decisions are made on the hardware level, software doesn't have to be compatible for it to see the benefits.

did ya know that you can gain cache performance by adjusting certain windows registry settings, i dont think windows is utilizing the level 3 cache of my P4 EE 3.4 Northwood CPU.
