AnandTech 6800 GS Review 7 Nov 2005
The 6800 GS cards will all sport NVIDIA's NV42 core. Previously, NV41 and NV42 cores were used on vanilla 6800 boards. The main difference between the two parts is that the NV41 is run on IBM's 130nm process (and was NVIDIA's first native PCIe part), while NV42 uses TSMC's 110nm process. And where there is a process shrink with no other major changes, higher clock speeds are more accessible.
