That was never the case. Go back even to 386 days and AMD or Cyrix were not always on par with Intel clock for clock. This only really flipped when Athlon came

That was never the case. Go back even to 386 days and AMD or Cyrix were not always on par with Intel clock for clock. This only really flipped when Athlon came out. You also had to think about DX vs SX, if you got L2 cache, 5x86 is really a 486, what is an Overdrive chip?, why does a PR166 CPU run at 100MHz, what is a Celeron, and why is 300A model so much faster than the original 300? Etc etc etc
