AMD Unleashed: Four CPUs, Two GPUs, All Overclocked

Benchmark Results: Unreal Tournament 3

3D Games: Unreal Tournament 3

Clearly the CPU is our limit here, as there is a massive amount of scaling seen. The quad-core Phenom X4 9950 BE easily bests its dual-core sibling. Even so, the Athlon 7750 BE still delivers playable performance at all resolutions.

Again, we see playable performance for each processor with AA and anisotropic filtering (AF) forced in the drivers. The main difference here is that the GPU is also limiting performance, as seen in the lower frame rates and tighter spacing of the processors at higher resolutions.

It comes as no surprise that adding another Radeon HD 4870 GPU does nothing for our performance at these settings. What is a bit disturbing, though, is that we actually see a slight performance drop at times. Is there some sort of CrossFire inefficiency under CPU-limited test scenarios?

The mighty Radeon HD 4870 X2 isn’t fazed by the added demands of forcing 4x AA and increased resolutions.

    In 2 or 3 years when QX9770 chips start showing up for $250-$300.

    Will AMD have a cheaper socket AM2+ compatible chip on the market that will outperform it?

    If so, AMD would be a nice alternative.

  • In 2 or 3 years Intel will have 16 cores on a single cpu, and amd tech will, as always, be useless, outdated, and worthless... Just like they are now.

    So did I miss somthing or where does it say what each of these processors is overclocked to. I get that the p2 x3 720be is at 3.67 but what about the rest of them. Am I missing it somewhere (very possible) or do I have to look back at your previous articles to figure it out? shouldn't that be on the test systems and configuration page. I am trying to sort through the data.

    Nice article Paul and some exhaustive work! Don't overlook the 780G/SB710 that also feature ACC for a price of $72

    making the Phenom2 x3 720 a viable option in the SBM budget category. I'm also going to be curious about the new Phenom2 x2 and Athlon2 x2 processors that are coming out June 2nd.

    Has anyone noticed the benchmarks for the i5's on anandtech yet?

    Great article guys - love the comparisons to the SBM machines - really gives some insight into CPU and GPU scaling and how much to spend on your processor versus your graphics for gaming builds. Thanks!

    I did. Considering the pricing scheme of the i5 (so close to AMD) and it's high performance numbers (so close to the i7) AMD is in big trouble.

    Intel will shift all the processors that are now under the i7 (even if the 920 is rumored to become EOL, one step down on it's portfolio, which means high end Intel dual cores, will go into or under the mainstream, where AMD already has a hard time.

    This doesn't make me very happy, even if I am an Intel fanboy. Aggressive pricing schemes are overrated. AMD needs something new. Now.

    ... BIG THX to the Tom's crew... was not so hard after all? ... now, thx to YOU, we have a info about intel, nVidia and AMD/ATi solutions... how they stack up in price/performance/cost of ownership... NICELY DONE!!!

    Yes thanks, many people complained in the system builder marathon and you listened to the complaints... great.
