Alpha suffered before.  The 21264 was late, and did not keep up in the

gives the clock rate as varying between 466 and 600 MHz, and
Wikipedia gives the clock frequency of the Pentium Pro as between
150 and 200 MHz.  The Pentium II Overdrive, according to Wikipedia,
had up to 333 MHz.

Is this information wrong?

No, but it misses context: The Pentium Pro was available in late 1995.
The 21264 was officially available in 1998, but when we ordered a
machine with a 500MHz 21264 (and needed it delivered before the end of
the year for budget reasons), they delivered a machine with a 21164a,
and then in the next year upgraded it to the 21264 (which probably
meant replacing the motherboard, not just the CPU package).

Intel released a 450MHz Pentium II in 1998, and the 500MHz Pentium III
on February 28, 1999.  AMD released the 600MHz Athlon in June 23,
1999, and won the GHz race with the 1000MHz Athlon in March 6, 2000,
with Intel's Pentium III following in March 8.  Meanwhile, the Alphas
could not keep up in MHz numbers, but I have no firm dates, only
memories from that time.
