Moore's law is a general trend, not a physical constraint on
chip designers. The 21264 has 15.2 million transistors in it.
It was followed shortly by the PA-8500 with about 130 million
transistor in it. Did *this* break Moore's law? No, it is
an apples to oranges comparison. The 21264 is a very complex
OOE CPU with 128 KB cache on it. The PA-8500 is basically the
previous generation CPU core shrunk from 0.5 um to 0.25 um,
leaving it occupying about 25% of the die and the rest filled
in with 1.5 MB of cache SRAM. Is the next high end RISC CPU
to be released (US-III?) going to follow this "mini-trend" and
weigh in at over a billion transistors? Not a chance.
Paul W. DeMone The 801 experiment SPARCed an ARMs race of EPIC
Kanata, Ontario proportions to put more PRECISION and POWER into
demone at mosaid.com architectures with MIPSed results but ALPHA's well
