Riva TNT
nVidia, a company that has become a household name for many of us, has been
hard at work at the drawing board inventing their next product, the successor to the Riva
128. Named after a highly explosive and volatile substance, this card is screaming
performance figures that are as staggering as its name. The Riva TNT, announced only
months ago, dropped the jaws of many onlookers as the massive performance numbers were
announced. With a fill-rate of 250 million pixels per second, and a maximum polygon
throughput of 8 million, the TNT, if it lives up to its promises, will set a new standard
in graphics acceleration.Features
