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'm not sure about how the G4 compared to Core2 in performance/watt, as comparisons between the two haven't really been made anywhere, as far as I can tell. When Apple switched to x86, they started with the Core Duo, an earlier chip. That chip has much better performance/watt than the G4.

Intel's very strict philosophy for the original Core line of chips was 2% performance increase for 1% power consumption increase. The Intel engineers were very strict about that rule, and due to it's success, all Intel x86 cpus that followed were designed with the same principles.
