Riva TnT 07 Jul 1998
nVidia Riva TnT. TnT = TwiN Texel
Architecture, which, like the Voodoo2, allows two textures to be rendered in one pass.
nVidia hope this 2D/3D chip will be the ultimate Voodoo2 killer. nVidia says the TnT
will do 2D faster than the Riva128ZX. It will render 3D in 24-bit color instead of the
16-bit color supported by current consumer 3D hardware, which gives a better picture.
nVidia claims that the TnT will have a fill rate of 250 million pixels per second,
unexcelled by anything on the market, and a triangle rate of 8 million triangles per
second, both much higher than even the Voodoo2 can do in SLI mode. Due September 1998,
will sell for around $150 to $200 for 8 and 16 MB cards.
Gamespot has a review of the
TnT-powered STB Velocity 4400.
