HAHA, whatever happened to Intel pledges 80 cores in five years? (article from 2006) http://news.cnet.com/Intel-pledges-80-cores-in-five-years/21...

The Nvidia Tesla K20 has 2496 cores (I know that it is a GPU and not a CPU)

People started caring a lot about power and mobile, combined with AMD basically shooting themselves in the feet repeatedly in the server space. AMD has delivered a large number of cores (you can cheaply put 64 in a box), but even for embarrassingly parallel applications, you'll struggle to get the same performance as a modern 16 core (real cores; 32SMT threads) Intel box due to smaller FP pipeline, slower clock speeds, etc. (note: not speculation; we have both types of machines in our labs)

Well, about the 80 core Intel chip, you may be interested in the Intel Xeon Phi that has about 60 cores.

Xeon Phi (nee Larrabee) looks interesting, but it's not a real product yet. I.e., you can't buy one for your desktop computer.

As others have pointed out, with AMD Opterons you can stuff 64 cores on a server motherboard today.

Well it is about to be available in about 2 months. From Intel: "The Intel Xeon Phi coprocessor 5110P is shipping today with general availability on Jan. 28 with recommended customer price of $2,649."
