Intel To Ship Xeon Phi For "Exascale" Computing This Year 77
MojoKid writes "At the International Supercomputing Conference today, Intel announced that Knights corner, the company's first commercial Many Integrated Core product will ship commercially in 2012. The descendent of the processor formerly known as Larrabee also gets a new brand name — Xeon Phi. The idea behind Intel's new push is that the highly efficient Xeon E5 architecture (eight-core, 32nm Sandy Bridge) fuels the basic x86 cluster, while the Many Integrated Core CPUs that grew out of the failed Larrabee GPU offer unparalleled performance scaling and break new ground. The challenges Intel is trying to surmount are considerable. We've successfully pushed from teraflops to petaflops, but exaflops (or exascale computing) currently demands more processors and power than it's feasible to provide in the next 5-7 years. Intel's MIC is targeted at hammering away at that barrier and create new opportunities for supercomputing deployments."

There's a difference in terms of target. Larrabee was initially supposed to be Intel's first shot at being competitive in the GPU market. This reuses a lot of the tech, but it's more like having a bunch of Xeon processors in a PCI-E slot. It's general purpose, massively parallel computing power, which could make it a sweet spot for things like video transcoding or CGI (as GPU solutions tend to be fairly lossy).
The interesting thing about this is that it could basically transform any desktop computer with a modern motherboard into a mini-supercomputer. With two PCI-E slots you can get over 100 CPU cores, which is rather nice as it's all off-the-shelf hardware (well, aside from the probably ridiculously pricey Xeon Phi boards themselves).
