Call of Duty: World at War
While not our favorite Call of Duty game, World at War certainly improves upon the graphics quality of previous versions. We play through the first few minutes of the Semper FI level by following a repeatable course and capture our performance results with FRAPS. We set the various graphics and texture options to their highest settings with AA at 2x and AF at 8x.
This game is not particularly hard on either the GPU or CPU, but we do hit a hard cap at 94fps. At 1680x1050 the Phenom II platform is able match either Intel platform in single card and CrossFire mode, although minimum frame rates favor Intel slightly. When overclocked, the Phenom II is only about 2% slower in average frame rates but minimum frame rates are 20% lower.
Adding a second card for CrossFire operation improves average frame rates by 12% and minimum frame rates decrease 2% for the Phenom II. The Intel Q9550 has an 11% increase in average frame rates and 4% in minimum frame rates. The Core i7 average frame rates improve by 13% and minimum rates decrease by 12%. Overclocking our processors resulted in a 2%~5% improvement in average frame rates with the Q9550 benefiting the greatest.
We have roughly the same performance results at 1920x1200 when comparing the platforms. The Phenom II is competitive with the Intel platforms in single card and CrossFire operation, though minimum frame rates in CrossFire mode trail the Intel solutions around 5% on average. Once we overclock the CPUs, the minimum frame rate is about 16% lower on the Phenom II compared to the Intel products.
Installing a second card for CrossFire operation improves average frame rates by 27% and minimum frame rates increase 16% for the Phenom II. The Intel Q9550 has a 28% increase in average frame rates and 24% in minimum frame rates. The Core i7 average frame rates improve by 29% and minimum rates increase by 30%. Overclocking our processors resulted in a 4%~5% improvement in average frame rates with the Q9550 benefiting the most.
We did not notice any difference in game play quality at either resolution between the platforms after playing through several of the levels. Each platform offered a very smooth and fluid gaming experience. We thought the higher minimum frame rates on the Intel systems would be noticeable during the action scenes in the jungle, but we honestly could not tell the systems apart during testing.

You might want to read the article a bit more carefully. From the test setup page: "Our decision to go with a 790FX/SB750 combination on the AMD side is strictly based upon performance. The 790FX is about 3%~5% faster on average than comparable 790GX products. AMD continues to recommend the 790GX/SB750 as the platform of choice for the AM2+ and upcoming AM3 products. We disagree from a performance viewpoint; the 790FX/SB750 combination is simply the best choice in our opinion. Of course you will typically pay about $35~$40 or greater for the 790FX boards, but if you intend on running CrossFireX, we think it is worth the additional cost."You *can* find less expensive motherboards, but what will the *overall* experience with those board be? I for one would take a better motherboard with a less expensive processor every time over a faster default CPU clock and a cheaper motherboard. The motherboard is just too critical a component to ever warrant skimping in my book. YMMV, naturally.

Should the fusion program that runs faster maybe be put into the calculations for AMD?CPUGuy - Monday, February 2, 2009 - link
Wow, I nearly forgot about that. I didn't see that mentioned as well. Fusion 1.0 is out and should be used in any and all AMD based benchmark reviews IMO.kuyaglen - Sunday, February 1, 2009 - link

Seriously, who cares for Crossfire (or SLI)?Please. Stop making those useless enthusiast's enthusiast reviews and come back to the ground, AnandTech.
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.
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.

lies buried in the single-GPU results included in these benchmarks.No difference. No difference at all! (and I count 1-2 fps as no difference).
But those aren't usually shown, because CPUs get tested under highly artificial conditions... to show their advantage... IN THEORY.
In real life gaming performance it makes no difference, if you just intend to play with your quad-core... this is the real interesting result that could justify this article, nothing else.

...that CF/SLI sucks. Anytime. Big time.It never made sense, it will never make sense.
The time, you come back and drop in another card of the same class, there is a new generation available that easily tops your grandmother-CF/SLI and furthermore adds even DirectX 11 support and a plethora of other features into the deal...
2 GPUs+ is a failed strategy - unless you are some scientist... working on a super computer... actually trying to achieve something... other than that it's highly efficient money-burning 2.0

It seems you are abit confused. The "Steam" hardware survey runs when Steam launches. SLI and Crossfire are not active on the desktop so Steam says "no crossfire or SLI detected." More people have SLI or Crossfire by a longshot then what you are seeing by a detection program that is failing miserably. Go pull Futuremarks independant ID results list if you would like to see SLI and Crossfire #'s. Also tons of people playing counterstrike source years later don't exactly count as the bulk of the comunity. This is a high tech cutting edge website for new data and information about computer electronics. If you want babyville information about basic garbage then you need to visit Znet.SirKronan - Monday, February 2, 2009 - link
"Seriosly, who cares for Crossfire (or SLI)?Holy smokes, man. Get out of here. You can get a P45 board for $100, overclock the crap out of a Core 2 duo/quad, a couple of 4850's for $300 and you've got a SERIOUS amount of gaming power. I was an early adopter of the Asus P5Q Pro with a 4850 to go with it. I've since switched, but while I had it, a second 4850 would've been a fantastic upgrade path. You can take two 4850's and an economical P45 motherboard and give the more expensive GTX 280/285 a run for the money, even winning in many games. 2x4850 is the "common man's" multi-GPU setup, and many many have been very successful with such a platform, without paying through the nose. When the 8800GT came out, and nVidia substantially improved SLI, the consumer was in a similar situation.
And look at all the moderately-priced, AMD boards that will take AMD's new cost effective X2's and X3's?? I think this review applies to A LOT OF customers. How many people out there have a P45 board? How many people out there have a crossfire capable AMD board?? And out of those, how many have a 4850?
Well, now you know what you'll get for an upgrade path. Now you have a realistic preview of performance gains if you add a second 4850 some day. In some games, the benefits are great, and it will be worth your while. Now you know how the new Phenoms compare if you have a compatible AMD motherboard, or were considering one.
Thanks, Anand for giving such consumers the heads up. Very useful article.

I agree that was a great reviewI am running a 3.2ghz x2 duel core on a MSI K9A2 platinum with 4gb of ocz 1055 and I have just installed my second His 4850 1gb of mem
graphics card
eventualy I hope to up my ram to 8 gb install vista or the win 7
and go to a 4 core cpu and a new pcu
my motherboard can hold 4 graphics cards
I still have not seen any tests with all AMD/ATI products on a vista win with that OC tool and with 4x 4850 1 gbmem
oh well all fun and games great article thankyou
