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.

If these Settings were used for the Phenom II 940, at least it is not as bad as I first thought:http://www.anandtech.com/weblog/showpost.aspx?i=55...">http://www.anandtech.com/weblog/showpost.aspx?i=55...
That would mean an NB frequency around 2450. That is quite okay though it can be tweaked a bit further.
Still, it would be nice to know which settings were actually used for the Phenom II.

That is a very, very well done article. Keep it up guys. Can't wait til' income tax and I am going to get a e8500 and a pII 940 to upgrade my P35 and 790GX, respectively.7Enigma - Monday, February 2, 2009 - link
Thank you for finally including this information in the charts!This has been a HUGE peev of mine for a while now and it really helps to see which card (or in this case system) is actually better than the other at a particular game where the average frame rate may not tell the whole story.
Please make sure the rest of the Anandtech crew starts using this format for future testing.

Although I understand the intent of using the highest OC possible I do believe the results can lead to another conclusion. A few of us discussing the CPU OC, CF results. It appears (so far) that the reason why the Q9550 came out ahead in CF results was a direct result of it's overclock. Some believe that if the PII 940 was OC'd that high (yes we read the other article about this) or the Q9550 was OC'd down, results would be different.The reason for this point of view is that most are not able to get Q9550 at 4.25GHz on air.

I found this article very informative. It now puts into perspective where the PII 940 stands in the gaming arena. Thanks Anandtech for taking the time to do it. I myself have 3 computers, 2 capable of of either the quad 9550(P45) or PII 940 Deneb(780g). It is very good to know that which ever solution I choose, xfire on P45 or single on 780g, I know the performance capabilities of both, and I like both. Hell, you got that Q9550 up to 4.05 oc for these tests? Wow! I knew they were capable, but to run these games that well under the load is alone impressive. You sure it was'nt the Q9650? I alone was going to shoot for a modest 3.8 for gaming, stability and temp management. In closing, it is also good to know that those who jumped on the I7 bandwagon real fast are sitting pretty, I know it was'nt cheap, but alot of those builders skimped on graphics.zenguy - Monday, February 2, 2009 - link
In your review, it you stated that your testing did not reveal any difference between the P45 and P48 for CrossFire Limits so a P45 board was chosen.However, based on a few other reviews I have read, the 4850 can be noticably limited by the P45 board and ergo I presume the limits on a 4870 1GB card would be much much higher.
An example of one such review is below...........

Could this explain the "Unusual Drop" in performance or unexpected low framerates for the Intel Platform that you noted?

I am 100% sure that the results of the Core 2 Quad 9550 wild be much higher with an Intel X48 chipset than with the P45 in Cross Fire.Never the les, the article DOES show that Phenom II 940 is competitive in real life gaming at High resolutions.

Yes the PII is a valid solution.AMD Finally re-entered the game in my Mind with the release.

Hammonds famous line in Jurrasic Park.Indeed, for 95% of folks, these ultra high benchmarks are useless. But for those of us in the 5%, thesy serve as a reminder on the ridiculous amounts of money we spend to squeeze just tha extra few FPS out. But then again the other 95% just dont get it...why?
Here is a paragraph I have kept near and dear for some years and it explains it eloquently.
"To upgrade or not to upgrade, that is the question that crosses many enthusiasts' lips on a daily basis. The upgrade bug is a high infectious, wallet-stripping disease that spreads fast once it gets a hold of you. Hardware manufacturers propagate this infection by offering you, the consumer, faster, more desirable hardware each month. Almost every facet of the hardware world begs you to get the next model up, or to break open the piggy bank and buy an 'upgraded version' of what you already have. Speak to a number of enthusiasts and they'll tell you that upgrading is more addictive than gambling (Biz387, 2003)."
So, you see, it's not our fault. Were simply sick. I type this as I play crysis at DX10 Very High spec everything at maximum @ 1900x1200@ 40fps average. Pulling about 830watts at the outlet, lol.

If I were to use your number, the inclusion of more mainstream benchmark results pulls in nearly 95% more hits to this website then it would be beneficial for both anandtech and it's viewer base. Puts things into prospective doesn't it? LOL
