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.

[2] The first graphics card that was based on the RIVA TNT chip was the Velocity 4400, released by STB Systems on June 15, 1998.

Later on when fully featured OpenGL drivers were made for the 3dfx line of cards, it was noticed that it was much slower when compared to its cut down MiniGL brother.

Again, like with the RIVA 128, the lack of Glide API support hindered Nvidia's opportunities for market share growth.

After all, unlike the rest of the competition, Nvidia had come close to the Voodoo2 in performance in some games, and beaten it in 32bit image quality.

[4][12][13][14][15] In what would become standard industry practice on a massive scale in later years, Nvidia released a budget version of TNT called Vanta.

TNT itself was used on several popular cards, such as the Diamond Viper V550 and STB Velocity 4400, both of which managed OEM wins with the likes of Dell and Gateway, among others.
