Get yer cores here, fresh hot, 80 of them …

Only 1.2TF performance.
Ok, I am officially impressed. The immediate questions are

a) can anyone actually program it
b) how hard do you have to work to feed this monster?
Data motion is hard. Very hard. You have fixed sized pipes. You see contention at dual core, and quad, as Clovertown shows, is not appropriate for memory bound codes on fixed/limited width memory pipes.
Regardless of those (not so minor) issues, all I can say is “wow” and good job Intel. Would love to get my paws on one of them.
