It's not too bad for an 1997 Top500 equivalent (well, at least as far as matrix multiplication is concerned). > Furthermore the word 'double precision' is nowhere there, so we can > safely assume single precision.

Intel touts that Knights Corner produces 1 TFlop consistently indedepent of matrix (block) size. The vector unit is 512 bits, Knights Landing will boost that to 124 bits, supposedly.

Parts like these will be useful for gamer markets, so presumably nVidia or AMD will be only too happy to leap into any gap that Intel offers. > For crunching get gpu's - as for intel - i hope they release cheap > sixcore cpu's and don't overprice 8 core Xeon... > > On Nov 16, 2011, at 10:52 AM, Eugen Leitl wrote: > > > > > http://seattletimes.nwsource.com/html/technologybrierdudleysblog/ > > 2016775145_wow_intel_unveils_1_teraflop_c.html > > > > Wow: Intel unveils 1 teraflop chip with 50-plus cores > > > > Posted by Brier Dudley > > > > I thought the prospect of quad-core tablet computers was exciting. > > > > Then I saw Intel's latest -- a 1 teraflop chip, with more than 50 > > cores, that > > Intel unveiled today, running it on a test machine at the SC11 > > supercomputing > > conference in Seattle. > > > > That means my kids may take a teraflop laptop to college -- if > > their grades > > don't suffer too much having access to 50-core video game consoles. > > > > It wasn't that long ago that Intel was boasting about the first > > supercomputer > > with sustained 1 teraflop performance.
