"So whilst Larrabee is a good demonstration of Intel getting really good at multi-core, it's not of much immediate interest."
You can bet is of interest to anyone who ties their software pricing to the number of cores.
I think Intel are talking about several hundred watts for the 32-core offering, but the 8-core Larrabee would be a perfectly reasonable chip to put in an SCC. This could all go mainstream *awfully* fast. Canonical have an OS for such a chip. Microsoft don't, until they change their pricing structure. The same goes for Oracle.
Make no mistake, Larrabee is awfully disruptive technology.
