When a developer says he wants a game to fire a ray in a certain direction, "our hardware will figure that out," McCombe said. "At the low level we do what we're told to do."
The GPU has 128 cores in four shader clusters, and delivers up to 300 gigaflops of performance with clock speeds up to 600MHz. The core can deliver ray-tracing performance of 300 million rays per second and 100 million dynamic triangles per second. The graphics core is being demonstrated at the Game Developers Conference being held in San Francisco this week.
