Intel Details Nehalem CPU and Larrabee GPU

Vigile writes "Intel previewed the information set to be released at IDF next month including details on a wide array of technology for server, workstation, desktop and graphics chips. The upcoming Tukwila chip will replace the current Itanium lineup with about twice the performance at a cost of 2 billion transistors and Dunnington is a hexa-core processor using existing Core 2 architecture. Details of Nehalem, Intel's next desktop CPU core that includes an integrated memory controller, show a return of HyperThreading-like SMT, a new SSE 4.2 extension and modular design that features optional integrated graphics on the CPU as well. Could Intel beat AMD in its own "Fusion" plans? Finally, Larrabee, the GPU technology Intel is building, was verified to support OpenGL and DirectX upon release and Intel provided information on a new extension called Advanced Vector Extension (AVX) for SSE that would improve graphics performance on the many-core architecture."

More Integrated Garbage?

So, this Larrabee, will it be another example of integrated graphics that "supports" all the standards while being too slow to be useful in any practical situation, even basic desktop acceleration (Composite / Aero)? If so, I've gotta wonder why they even bother rather than saving some cash and just making a solid 2D accelerator that would be for all intents and purposes functionally identical.

No, far, far, from integrated garbage. Larrabee will actually have uses as a supercomputer CPU:

"It was clear from Gelsinger's public statements at IDF and from Intel's prior closed-door presentations that the company intends to see the Larrabee architecture find uses in the supercomputing market, but it wasn't so clear that this new many-core architecture would ever see the light of day as an enthusiast GPU. This lack of clarity prompted me to speculate that Larrabee might never yield a GPU product, and others went so far as to report "Larrabee is GPGPU-only" as fact.

Subsequent to my IDF coverage, however, I was contacted by a few people who have more intimate knowledge of the project than I. These folks assured me that Intel definitely intends to release a straight-up enthusiast GPU part based on the Larrabee architecture. So while Intel won't publicly talk about any actual products that will arise from the project, it's clear that a GPU aimed at real-time 3D rendering for games will be among the first public fruits of Larrabee, with non-graphics products following later.

As for what type of GPU Larrabee will be, it's probably going to have important similarities to we're seeing out of NVIDIA with the G80. Contrary to what's implied in this Inquirer article, GPU-accelerated raster graphics are here to stay for the foreseeable future, and they won't be replaced by real-time ray-tracing engines. Actually, it's worthwhile to take a moment to look at this issue in more detail."
