Battlefield 2 High-End Performance
We have finally ironed out our issues with BF2 and SLI, so this time around we get to compare ATI and NVIDIA in multi GPU configurations. DICE has said in the past that results over 100 fps are not always reliable. It will suffice to say that CrossFire leads SLI at the low two resolutions. Putting a finer point on it goes against what we know of the benchmark's behavior. Interestingly, at higher resolutions (above 1600x1200), while the 7900 GTX and 7900 GT fall further behind ATI's single card solutions, SLI is able to take the lead from CrossFire. This would seem to indicate that SLI has a bit more of a CPU limitation at the low end than CrossFire, but that it is ultimately much more efficient in BF2.

there is not a 256bit version of the 7600 gt as far as we knowinthell - Friday, March 10, 2006 - link
hmmm, must be a mis-print on NEWEGG they have a XFX and a EVGA with 256bitsupafly - Thursday, March 9, 2006 - link
Could you do some benchmarks for COD2? If you have the time... thanks :)vaystrem - Thursday, March 9, 2006 - link
It would be really helpful if you had SLI data and Single card data seperate on each benchmark. If a single card is beating an SLI setup - I can figure that out for myself. In the current charts a lot of cards that should be there, or could be there, aren't because your running out of space.I mean the high performance benchmarks include nothing lower end from ATI than a 1900XT? You are also only reporting on the SLI performance of the 7600GT in the first 4 benchmarks. Most of us aren't going to go out and drop the cash on an SLI setup right off the bat but instead use it as an incremental upgrade.
Just a thought.

I agree they should be split up, it just looks too cluttered up.R3MF - Thursday, March 9, 2006 - link
hoorah for the 7900GT, just dropped £244 on one inlcuding p&p.Teetu - Thursday, March 9, 2006 - link
they mention they didn't run all the tests they usually do... why not? time?DerekWilson - Thursday, March 9, 2006 - link
There were a lot of factors that went in to our decision to cut down the number of tests for this article. Our testing is not over, as we are planning a follow up article as well.5150Joker - Thursday, March 9, 2006 - link
You mention the X1900 XTX costs $580-$650 yet you can find it at a popular e-tailer like Newegg for as low as http://www.newegg.com/Product/Product.asp?Item=N82...">$509 for an OEM XTXand http://www.newegg.com/Product/Product.asp?Item=N82...">$531.99 for a retail XTX (MIR)classy - Thursday, March 9, 2006 - link
I never really noticed how bad Crossfire sucks. While a 1900 xtx is about as faster and in many cases faster than 7900, when put in Crossfire vs SLI it just blows.
