The RIVA TNT, codenamed NV4, is a 2D, video, and 3D graphics accelerator chip for PCs that was developed by Nvidia and released in March 1998. It cemented Nvidia's reputation as a worthy rival within the developing consumer 3D graphics adapter industry. It succeeded the RIVA 128.
RIVA is an acronym for Real-time Interactive Video and Animation accelerator. The "TNT" suffix refers to the chip's ability to work on two texels at once (Twin Texel).
The first graphics card that was based on the RIVA TNT chip was the Velocity 4400, released by STB Systems on June 15, 1998.
