GeForce 256 SDR: specs and benchmarks

Summary

NVIDIA started GeForce 256 SDR sales 11 October 1999. This is a desktop graphics card based on a Celsius architecture and made with 220 nm manufacturing process. It is primarily aimed at gamer market. 32 MB of SDR memory clocked at 0.14 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 1.144 GB/s.

Compatibility-wise, this is a single-slot graphics card attached via AGP 4x interface.
