Adam - re: "several months ago IBM demonstrated a 1.1 Ghz PowerPC
technology. It was based on copper, "

Several months ago at the ISSCC, IBM demonstrated two chips. One was a 1.1 Ghz integer processor with "only " 1 million transistors. It was fabricated with ALL ALUMINUM Interconnect.

The second processor they demoed - and gave a paper on - was a PowerPC made with 6 layers of copper and an Leff of 0.12 microns - probably a 0.18 micron Drawn CD - as well as local interconnect.

That PowerPC had a TOP SPEED of only 480 MHz.
