The NVIDIA G80 (8800GTX), with 128 Shader units, is the first DirectX 10 compatible graphics card ever. The card sports an attractive-looking cooling solution well in keeping with such a large card (it’s 11 inches long). Testing saw the card running a bit hotter than the G70 and G71 series. It ran at 80 degrees under load; the G71 had rarely crossed the 60 degree mark!
The G80 has 768 MB of GDDR3 memory (1.8 GHz). F.E.A.R. saw a staggering 150 fps at 1024 x 768 with 4x Antialiasing (AA) and Anisotropic Filtering (AF) enabled. Similarly, Prey saw just over 202 fps at 1280 x 1024, at the highest settings.
For now, this is the fastest DirectX 9 card ever! Did we mention it supports SLI as well as Quad SLI? ATI’s response—the R600 is highly anticipated, and if it’s anywhere in the performance region of the G80, we should be getting a lot more realism in our games a whole lot sooner than we could’ve imagined!
