The triple-channel controller will appear on both desktop and server/workstation offerings, and it will support three memory modules per channel. Using current 2GB DDR3-1333 modules, that means you’d be able to cram 18GB of RAM into a single desktop PC and yield a theoretical maximum of 31.99GB/s of bandwidth?impressive, to say the least. Interestingly, Nehalem chips will only feature 256KB of L2 cache per core and 8MB of L3 cache per chip. That’s a little on the light side compared to Intel’s existing 45nm quad-core parts, which have 12MB of L2 cache (one shared 6MB L2 cache per die). AMD’s upcoming 45nm quad-core offerings, for reference, will have 512KB of L2 cache per core and 6MB of L3 cache per chip.

Not only that, but Gelsinger also confirmed Larrabee will be compatible with DirectX and OpenGL application programming interfaces. In other words, while Intel will be pushing for different rendering paradigms like ray tracing, the company won’t have to wait on developers to make its silicon useful to gamers?Larrabee should be able to run existing games.

Nehalem is arriving in the fourth quarter.
