OK, I admit I'm commenting based on a pastebin page purporting to be a comment from Linus on RealWorldTech and I can't get to the forums to read the actual content... but having said all that, I don't agree. While your characterization of Phi as "Replacing 8 powerful Xeon cores with 60+ slower ones per socket" is sort of/mostly fair. Phi isn't really the dumb cacheless cores that are mentioned. Moreover, Phi very much is a niche product designed specifically for a market that is not exactly enjoying substantial performance gains in the last few generations of mass market Xeons. Instead I thought of some other products... like the 8 core ARM SoCs for handys and other mobile devices; which, lets be honest, is much less than a well designed & implemented SoC that is ideally suited for the use it's being marketed for. The Adepteva Epiphany chips (available on their Parallella boards) fit this description almost perfectly, as do Kalray and GreenArray chips. Though I guess one could make the argument that they're all very much niche products. Anyway, I'm not sure we've really got enough information to comment further.
