A ray tracing demo depicting the prowess of Intel's discrete GPU Larrabee was showcased at the Intel Developer Forum 2009 in San Francisco. Sean Maloney, vice president and co-general manager of Intel Architecture Group, confirmed that Larrabee's architecture would eventually be integrated in desktop CPU at some point in the future.
Bill Mark, senior research scientist, Intel, showed a ray tracing demo based on the id Software game - Enemy Territory: Quake Wars. "We took the content, the textures, and geometry, pulled it out of that game and put it into our ray tracing engine," said Mark.
The demo was based on earlier or initial versions of Larrabee chip and Intel hasn't specified the number of cores that Larrabee chip would pack.
Mark explained ray tracing technology as allowing "you to simulate the interaction of light with matter in a way that's accurate and makes it really easy to get effects like light and shadows."
The demo was written in C++ and Mark said, "If you look at the water. That's done with only 10 lines of...code." With advent of Windows 7 having DirectX 11 will have ray tracing support based on Intel's x86 microarchitecture.
Back in May, we got to see a blurry image of Larrabee die in presentation of Justin Shattner, vice president and CTO, Intel. The Larrabee discrete GPU is scheduled to release around second half of next year and expected to compete with ATI as well as Nvidia GPUs.
