press releases always put the new shiny thing in the best light.
they're probably thinking of a conventional compute node,
(say, 32 cores, 2.3 GHz, 4 flops/cycle, or 16c and 8 f/c - 
either way totalling 294 Gflops for 300W or less.)

debatable whether we can honestly claim that's shipping.
K10 is .78 Gflops DP/W or 17.2 SP.  I wonder of the 75 goal
is merely a 4.4x improvement....
