PB, Re: ">>The blazing-fast performance offered by the Model 270 and Model 170 is in part derived from the IBM-pioneered copper
wiring technology incorporated into the 64-bit POWER3-II chip. Copper increases microprocessor performance
substantially over chips that use aluminum wire. A single POWER3-II chip contains about 400 meters of copper wiring.<

This is what I mean about IBM hyping its process technology every chance they get."<<

I think what IBM has done in that chip design is to maximize what we used to call "work" done on a per CPU cycle basis, and not push for high megahertz at all. In the server space, SPECint_rate95 sells, not megahertz, as Jim says. Still, 375 seems awfully slow, doesn't it?

Matched against Sun's 4-way 400 MHz Enterprise 450, a 4-way Model 270 provides about 40
percent greater power, according to SPECint_rate95, a benchmark that measures commercial processing performance.
