Actually the Pentium Pro is made up of two separate chips in one ceramic package. The CPU chip uses a 0.35 micron process (0.6 micron on the 150 Mhz). However the L2 SRAM chip uses a 0.6 micron process for all 256K units (the 512K L2 chip on the 166 PPro and some 200 PPro's uses a .35 micron process). So the bulk of the Pentium Pro lineup does in fact absorb 0.6 micron capacity.

You are correct about the 486/66 (and lower) and Pentium 60/66 being 0.8 micron processes. Those production runs were phased out to accomodate the Pentium PCI chipsets that also ran on the 0.8 micron process. My earlier post should have drawn a correlation between the slowdown in P5-90/100 production (0.6 micron) and the PenPro ramp which does require substantial 0.6 micron capacity. Thanks for the correction.
