Since this thread doesn't seem to be for x86 only, I'll link to a collection of fresh presentation slides regarding the very promising PA Semi CPU (seems, it will have a really good performance/watt ratio - much better than Cell,.. and the rest anyway ):

It is compatible to PowerPC. So Glucas and Mlucas might be the first GIMPS clients running on it.

Most interesting for us here might be the mentioned performance of 24 GFlop/s FFT performance (resulting from their simulations) at 2 GHz, which means 13 W typ. TDP ("Intel TDP") or 25 W max. TDP ("AMD TDP"). The difference between these numbers is greater than usual, because the chip has much more control over what to switch on and of (it's a CPU designed for performance/watt from the ground up).
