Seems impossible to me. The XDR and Flex-IO interfaces each look to be 1mm x 9mm. If total chip power consumption is 20W, how much can be dedicated to I/O? Maybe 5W? Spreading out 5W over 18mm^2 seems pretty simple.

In most high-end microprocessors, worst-case thermal characteristics usually show the highest temperature in the FPU, while I/O is normally fairly cool.
