There was a chance that they would commoditise it, for experimental purposes, but that didn't seem to pan out. Their current plans are indicated here: http://techresearch.intel.com/articles/Tera-Scale/1421.htm They hope to have systems shortly, and to allow selected people online access from mid-2010, so I would guess that the first ones that could be bought would be in early 2011. If all goes well. I have absolutely NO idea of where they are thinking of placing it, or what scale of price they are considering. Regards, Nick Maclaren.

Nick, SCC and Larrabee are different species. Both have plenty of relatively simple x86 cores on a single chips but that's about only thing they have in common. 1. Larrabee cores are cache-coherent, SCC cores are not. 2. Larrabee interconnects have ring topology, SCC is a mesh 3. Larrabee cores are about vector performance (512-bit SIMD) and SMT (4 hardware threads per core). SCC cores are supposed to be stronger than Larrabee on scalar code and much much weaker on vector code. 4. Larrabee was originally intended for consumers, both as high-end 3D graphics engine and as sort-of-GPGPU. Graphics as target for 1st generation chip is canceled, but it still possible that it would be shipped to paying customers as GPGPU. SCC, on the other hand, is purely experimental.

In fact GPGPU is canceled together with GPU. So now 45nm LRB is officially "a prototype". http://www.anandtech.com/weblog/showpost.aspx?i=659 |
