Phenom ii x4 945 vs Athlon ii x4 635

Before you click on the links, I just need to inform you that I am loyal to Tom's Hardware, and this is basically the only Forum I am a member of, but it doesn't hurt to check benchmarks by other websites. The links are what I use to compare processors.

Hope these can help you. By the way, just look at the bottom part on Andatech after selecting the processors to see the gaming benchmarks. I also selected Phenom 940 since I couldn't see 945

There's practically no gaming difference so long as your CPU speed is above 3.0GHz. And the Athlon II x4 635 should OC to well over 3.2GHz (this process can be a bit complicated. Why do you ask though?

If you can afford it without sacrificing on your graphics or PSU, a Phenom II x4 955BE is the best AMD CPU for price/performance if you consider how easily the Black Editions overclock.

This resource at Tom's pretty much answers your question perfectly: http://www.tomshardware.com/reviews/gaming-cpu-overcloc...

Notice that both CPUs are in the same bracket. Note: all CPUs are assumed not to be overclocked in these charts.

The Phenom has L3 cache which is worth around an extra 10-12% performance when gaming

i thought so before, about l3 cache thingy  

That's terribly misleading and mostly not true. If you play Metro 2033 with an Athlon II x3 and a 6950, you're not gonna get 12% better graphics just if you use a Phenom II with Level 3 cache. If that were the case, then the Tom's CPU ranking wouldn't agree with what I said earlier: (http://www.tomshardware.com/reviews/gaming-cpu-overcloc...).

The L3 cache is handy. But it's not going to affect gaming performance nearly as much as simon says. Tom's ranking chart is based on more testing than any of you have done and is consistent with benchmarks I've seen everywhere else. Notice the Athlon II x3 is ranked above slower clocked Phenom II x3's and x4's. That's because the clock speed matters more than the cache. Also, Core 2 Quads don't have L3 cache--notice where they end up on the charts.

I can definitely attest to the power of the Athlon II x4 635. I have one powering one of my Crossfire systems and it is a pretty fast cpu. I haven't run into any game as of yet that it could not handle fine.

what if i buy athlon ii 640 instead of phenom ii x4 955/965???

In terms of price/performance, that's a better buy. I like the Phenom II x4 955BE because it's unlocked and I overclock. But the Athlon II 640 should OC nicely still and OC'ing is unnecessary right now anyways.

I already have Athlon II x4 635 i dont see it worth upgrading to 640

See athlon 645 compared to phenom 955 here http://www.anandtech.com/bench/Product/188?vs=88&i=2.3.... left for dead 2 comparison of AMD CPUs here http://www.tomshardware.com/charts/desktop-cpu-charts-2... various gaming CPUs compared including 645 and 955 here http://www.tomshardware.com/reviews/best-gaming-cpu-cor... as you can see the 955 is maround 10-15% better than the athlon partly due to a slight increase in clock speed mainly due to L3 cache.

i better wait for desktop cpu liano or either for bulldozer

I am still playing with that resolution.

Just check my current config.

yup..thats my config!!

What would be good enough for me??  

So basically, your CPU is solid (especially with a slight OC) and if you have a 5770, your GPU is pretty good.

With monitors, you'll probably want a 22" 1920x1080 monitor. That's pretty standard and runs around $120 to $150. You can sometimes find deals on 1600x900 monitors, but that's awkward and not a top option.

hmmm

I'm using penom x4 945 with mabo jetway amd 790 + 128 side port. I compare with Intel i5 650 + mabo gigabyte H55-usl3, bot using 4Gb ram, seagate 250gb hdd and XP pro sp2. The result is not so much diffrent, for my daily computing (internet, email, open office, gaming such as EA red alert or general, photoshop). Both loading time are still slow (around 20-30second) to load windows, same speed to open other program. The main problem is the speed of my harddrive, "the unresolve bottle neck", faster harddisk cost me more then 4time expensiver then the standar one. I try a software called "Super Speed super cache" it help to make it faster, but not stable (sometime).

Maybe if I buy Fast SAS Harddrive my problem will solve better then just buy new prosessor, but I do not have enough money for that... My budget is not more then $500 overall  )

Not knowing the OP's local pricing or product availability (or budget), I would suggest moving that 635 and HD5770 into an AM3+ motherboard with some new DDR3 (memory prices are probably hitting the bottom).

It then becomes a question of whether that new AM3+ motherboard will have CrossFire/SLI capability, and whether the OP wants to snag another HD5770 (they are EOL, but inexpensive when you can find one).

And the new DDR3 memory speed will determine the 'sweet spot' for over-clocking his 635, which should have no issues at 3.3-3.5GHz with after-market cooling.
