Additional Details:

The RIVA TNT typically operates with a core clock speed of around 90 MHz. It supports resolutions up to 1600x1200 with high refresh rates. The increased texture fill rate and memory bandwidth make it a substantial upgrade over the RIVA 128. The RIVA TNT was a key competitor to the ATI Rage Pro and S3 Virge series. Its strong performance and features helped solidify NVIDIA's position as a leading graphics card manufacturer. The card uses a 0.25 micron manufacturing process. It also featured support for trilinear filtering and specular highlighting which further enhanced visual quality in games and applications. The NVIDIA RIVA TNT was a popular and influential graphics card that helped to push the boundaries of 3D graphics on the PC.
