RE: <The initial speed problem was mostly process technology related. Paul>

I've got a new theory. Intel has had stability problems in their sram cell due to too much leakage. Everyone was wondering how they could achieve those IDsat values with the IOFF values and the answer was that they couldn't! Fast wafers had sram stability problems and zero yield while slow wafers worked functionally but were, of course, slow. So it would sound like a speed problem.

This would account for your hearing that the problem was solved by tweaking Vt with the ion implanter and for CPU News hearing that the problem was in the on-chip L2.
