Too bad that Intel is having no significant competition on the server/workstation front, so no need to rush either - the Ivy Bridge based Xeon E5 and E7 processors are finally rolling out towards the end this year, but with more cores than originally expected. Meanwhile, the Xeon Phi MIC/co-processor/accelerator gets segmented into more SKUs and a new stepping that clocks things up to 1.238 GHz (from 1.1GHz) with roughly the same TDP and form factor.
