NVIDIA GeForce 7900 GX2 Specs
Each GPU on the GX2 boards is a full G71, which means 8 vertex units, 24 pixel units and 16 ROPs as the primary config.Clocks sit at 500MHz for each GPU core (across all clock domains), with 600MHz memory clock. That gives the following combined rates. And before you go nuts, I know they're just theoreticals, but they do serve a purpose.

Comfortably the fastest consumer graphics configuration on paper, the performance shown in the table above should translate to the fastest real-world graphics performance. Indeed the setup might well hold that title for all of 2006...
