Intel's Larrabee just won't die, will it?
Intel are adamant of entering into this market, and with the money they have - there's obviously no stopping them.
Intel are planning for a release in 2012, codename is "Knight's Corner", it's a 22nm HPC part and will hopefully compete with NVIDIA's Kepler and Maxwell GPGPU parts.
Intel has currently planned for it to have more than 50 cores, once they get down to 22nm. The TDP's will hopefully be good and "Knight's Corner" should at least come out before NVIDIA's Maxwell part. Intel plan to hit 22nm before the second half of 2011 while TMSC and GloFo won't be climbing the 22nm wall anytime before 2012.
