Intel Gives First Demo Of Larrabee Graphics Processor

By Antone Gonsalves September 23, 2009

Intel on Monday conducted the first demonstration of its long-awaited Larrabee graphics processor, which will launch the chip maker into competition with Advanced Micro Devices and Nvidia in the high-end graphics market. Sean Maloney, chief sales and marketing officer for Intel, showed off a working Larrabee at the Intel Developer Forum in San Francisco. The graphics processor was used to render a game-like environment built on ray tracing, a computing-intensive technique for generating 3D graphics. The technique is particularly useful in rendering realistic shadows and reflections. Larrabee was used in conjunction with Gulftown, codename for a six-core processor scheduled for release next year. The chip is based on Westmere, codename for a 32-nanometer variant of Intel's current 45-nm Nehalem microarchitecture. The first Westmere-based chip is scheduled to ship in the fourth quarter of this year.
