The Register is back with more information from Hot Chips about Intel's Xeon Phi coprocessor, which seems to be much more than just a GPU in drag.  Inside the shell you will find at least 50 cores and at least 8GB of GDDR5 graphics, wwith the cores being very heavily modified 22-nanometer Tri-Gate process Pentium P54C chips clocked somewhere between 1.2-1.6GHz.  There is a brand new Vector Processing Unit which processes 512-bit SIMD instructions and sports an Extended Math Unit to handle calculations with hardware not software.  Read on for more details about the high-speed ring interconnects that allow these chips to communicate among themselves and with the Xeon server it will be a part of.

"Intel has been showing off the performance of the "Knights Corner" x86-based coprocessor for so long that it's easy to forget that it is not yet a product you can actually buy. Back in June, Knights Corner was branded as the "Xeon Phi", making it clear that Phi was a Xeon coprocessor even if it does not bear a lot of resemblance to the Xeon processors at the heart of the vast majority of the world's servers."
