CrossFireX and the Phenom II X4 940 – Competitive or Not?

Crysis Warhead
Crysis Warhead is an update to the original game with a storyline that takes place on the other side of the Island during the same time-period as the first. The game features an enhanced and optimized version of the CryEngine 2 but is still a resource monster. We set the graphics options to Gamer, DX10, and 2xAA and play back a timedemo that covers the Ambush level. We have to admit at these settings that the game looks fantastic during action scenes and game play is acceptable.
At 1680x1050, all three platforms are clustered together in single card and CrossFire configurations. We also see why a single GPU card can be a better value than a dual GPU solution at this resolution in certain games. It is not until we overclock that we notice some separation between the platforms with the i7 taking a decent lead, but its minimum frame rates do not improve compared to a single card setup. However, our Phenom II setup offers the best minimum frame rates when overclocked and actually offers a slight improvement over its single card scores.
Adding a second card for CrossFire operation improves average frame rates by 2% and minimum frame rates decrease 12% for the Phenom II. The Intel Q9550 has a decrease of 1% in average frame rates and 19% in minimum frame rates. The Core i7 average frame rates improve by 8% and minimum rates decrease by 20%. Overclocking our processors resulted in a 22%~36% improvement in average frame rates with the Core i7 benefiting the greatest.
Our 1920x1200 test follows a similar pattern with all three solutions equal in single card testing and CrossFire showing a slight advantage to the i7. The Phenom II is slightly ahead of the Q9550 when overclocked, though it is at a 7% clock speed disadvantage. We have noticed CryEngine 2 will respond to improved memory bandwidth and latencies as we clock up the processors. The i7 holds a 14% advantage in average frame rates while the Phenom II once again impresses us with the best minimum frame rates when overclocked. However, not having a 20fps minimum frame rate is a disappointment with our multi-GPU setups. The NVIDIA 260/285 solutions scale better in SLI than the ATI HD 4870 products. We hope that ATI can improve their drivers for this game.
Adding a second card for CrossFire operation improves average frame rates by 20% but minimum frame rates do not change for the Phenom II. The Intel Q9550 has an improvement of 17% in average frame rates and a decrease of 6% in minimum frame rates. The Core i7 average frame rates improve by 27% and minimum rates increase 18%. Overclocking our processors resulted in a 14%~22% improvement in average frame rates with the Core i7 benefiting the most.
After playing through the several levels on each platform, we thought the Phenom II 940 offered a better overall gaming experience in this title than the Intel Q9550 based on smoother game play. It is difficult to quantify without a video capture, but player movement and weapon control just seemed to be more precise. Of course, if you have the funds, we would recommend the i7 platform for best possible performance.

"Seriously, who cares for Crossfire (or SLI)?Please. Stop making those useless enthusiast's enthusiast reviews and come back to the ground, AnandTech."
--Whats down to earth? Intel Celeries and IGPs'? They did both average use benches with single GPU and enthusiast class benches with dual GPUs and overclocking. how could you get your panties in a bunch like so easily. did you even bother to read the article?
"Please, go ahead, check the Steam survey hardware list.
Then tell me: How many people out of 100 do have SLI/Crossfire.
Then laugh.
Then stop testing this shit like it was important."
--Once again, same worthless comment. they didnt just test crossfire
"And here my suggestions for constructive improvement:
Test the new generation of HDDs with 500GB platters (e.g. Seagate 7200.12 series)
THAT would be interesting, because EVERYONE needs a good HDD, but no one needs Crossfire."
--ugh. saying eveyone needs the latest and greatest type of harddrive is like saying everyone needs crossfire and SLI.
going as far as breaking down your entire retarded post was a complete waste of time just to call you a douche bag but i guess it had to be done

The user "Finally" is right (although a tad abrasive). You don't need CF or SLI to run any of those games at an acceptable frame rate. Furthermore, the mainstream crowd does outnumber the enthusiast crowd using CF/SLI by many fold. So it would have made more beneficial to show both CPU stock and overclock results using just a 4870.Heck, they could have added a PII 920 at stock and overclock and a 4850 just to make it interesting. Maybe one day we will see such a setup tested.

With SLI/CF the CPU becomes more of the bottleneck then it would be with just one GPU. So, testing with SLI/CF shows more of a difference between the CPUs then it would with just a single card.Gary Key - Monday, February 2, 2009 - link
This is not a GPU comparison per say, it is a platform comparison. We set the game options to a blended mixture of quality and performance in order to keep the GPU setup from becoming the limiting factor when possible. This is explained in further detail in page two.CPUGuy - Monday, February 2, 2009 - link
Although I understand your reasoning and to a degree it make sense. However, many are using or attempting to use 4xAA max settings at 1680 (at the very least). Therefore, it would be very informative to many of use what we could expect.This is with the expectation that we are no longer worried about just CPU scores but platform scores. IMO, reviewers should start looking at the platform as whole in reviews like this as many are looking at it that way. If it were true that one motherboard performed exceedingly better then another a CPU only benchmark would make sense.

The article went live before it was completed. Page 10 is in and I will update it late tomorrow with power consumption numbers. Just finishing the power tests on the i7 with the same power supply we use on the other setups.
