XFX GeForce 7900 GT 550M Xtreme VIVO

For testing the 7900 GT Xtreme, we used an Athlon 64 3800+ processor on a DFI LANParty NF4 SLI-DR motherboard. We also used 1GB of low latency Corsair DDR (TWINX1024-3200XL) and a 120GB Maxtor SATA hard drive. The 7900 GT Xtreme was tested in both single and SLI configurations and compared to an ATI Radeon X1900 XTX with reference clock speeds. Although an X1900 XTX typically sells for $200+ more than a 7900 GT, the XFX 7900 GT Xtreme holds up rather well against it in our test system.

Performance Comparisons with 3DMark06 v1.0.2 Details: http://www.futuremark.com/products/3dmark06/

3DMark06

Futuremark recently launched a brand new version of its popular benchmark, 3DMark06. The new version of the benchmark is updated in a number of ways and now includes not only Shader Model 2.0 tests but also Shader Model 3.0 and HDR tests as well. Some of the assets from 3DMark05 have been re-used, but the scenes are now rendered with much more geometric detail, and the shader complexity is vastly increased as well. Max shader length in 3DMark05 was 96 instructions, while 3DMark06 ups the number of instructions to 512. 3DMark06 also employs much more lighting, and there is extensive use of soft shadows. With 3DMark06, Futuremark has also updated how the final score is tabulated. In this latest version of the benchmark, SM 2.0 and HDR / SM3.0 tests are weighted, and the CPU score is factored into the final tally as well.

As you can see here, a solo 7900 GT Xtreme performs quite well, especially when compared to the X1900 XTX that costs quite a bit more. As expected, when combining two cards in SLI, the performance is quite a bit better.
