"The ecosystem driving real-time ray tracing is immense – tens of millions of GPUs, industry standard APIs, leading game engines and an all-star roster of game franchises," said Nvidia PC business senior vice-president Jeff Fisher.
"This killer lineup of Super GPUs delivers even more performance for demanding PC gamers and ensures that they're prepared for the coming wave of real-time ray tracing blockbusters."
