RE: <Coppermine will launch at 667MHz because of the holdover P856 version, she said.>

<What a mysterious sentence. I believe that P856 is the 0.25u process. Does this mean that there was an 0.25u Coppermine? Or are they starting with the 0.25u PIII, shrinking it in a way that doesn't use the full P858 and then adding L2 cache?

Also, wasn't the original plan to intro the 0.18u Cumine at 600 MHz? Now they are kludging around but moving up to 667 MHz. Very strange.>

The "holdover P856" version is probably the recently released .25u PIII-600. Starting CuMine at 667MHz would position it as a high-end part, coexisting with the slotted .25u PIII line.

This may be a very important clue of a change in the roadmap: continue slotted PIII/PC100/PC133 for a long time, well into the next year. The DRDRAM problems or poor CuMine yields would be behind such change.
