IBM "IBM likes to go on and on about the transaction processing power and I/O bandwidth of its System z mainframes, but now there is a new and much bigger kid on the block. Its name is the Power Systems IH supercomputing node, based on the company's forthcoming Power7 processors and a new homegrown switching system that blends optical and copper interconnects. The Power7 IH node was on display at the SC09 supercomputer trade show last week in Portland, Oregon, and El Reg was on hand to get the scoop from the techies who designed the iron. This server node is the heart of the 20 petaflop 'Blue Waters' supercomputer being installed at the University of Illinois."

I've yet to see an X86 chip that can match the power-to-performance ratio of the ppc,

You haven't been paying attention, then.

Steve Jobs said, in the 2006 MacWorld keynote, that Intel's Core Duo had 4x the performance/watt of the PowerPC chips they were using.

The numbers he gave place the G4 doing a tad better than 1/4th the performance/watt, and the G5 doing a little worse than 1/4th.
