Elite Bastards posted a Foxconn GeForce 7900 GS (FV-N79SM2D2) video card review

The GeForce 7900 GS is (unsurprisingly) based around the 90 nanometre G71 architecture that powers the rest of the GeForce 7900, and indeed 7950, series of NVIDIA parts. However, the GeForce 7900 GS is the first part released by NVIDIA that uses a cut-down version of the core - While the rest of the range enjoys a full twenty-four fragment pipelines (or six fragment quads) coupled with eight vertex shaders, the 7900 GS finds itself with one quad of pipelines disabled (leaving it with a grand total of twenty) as well as a single vertex shader turned off, giving it seven in total. Naturally, this configuration allows NVIDIA to use cores which have come out of the manufacturing process with faulty fragment pipelines or vertex shaders, thus meaning that less dies are wasted thanks to the built-in redundancy in these chips.

Aside from the disabled fragment pipelines and vertex shader, the GeForce 7900 GS is identical in every other way to the GeForce 7900 GT, meaning that it comes complete with a 256-bit memory bus carrying 256MB of RAM, 16 ROPs, and core and memory clock speeds of 450MHz and 660MHz respectively.
