The Voodoo2 was released in February 1998 to replace the original Voodoo Graphics (SST-1).
Performance was increased by adding an extra TMU (Texture Mapping Unit), adding faster RAM and increasing the clock-freuqency to 90MHz. Each TMU has it's own 64-bit memory interface and can address 2MB texture memory on 8MB models, and 4MB texture memory on 12MB models.
One PC can fit two Voodoo2 cards using SLI (Scan Line Interleave) technology. This doubled rendering throughput and increased framebuffer memory allowing a resolution of 1024x768. The original Voodoo Graphics could do SLI as well, but this was not utilized in normal consumer versions. The Voodoo 2 SLI was a strong performer. It could out-perform a Riva TNT 2 in Unreal (3dfx glide optimized game) and was comparable with the Voodoo 3 2000/3000. Enthusiasts loved the Voodoo 2 for being the last 3D-accelerator which could be installed in their new PC. This led to various attempts on improving drivers and running modern games on a Voodoo 2 SLI setup. For example, Doom III, which is playable on a Voodoo 2 SLI setup. |
