The table on page 2 is very interesting for me. The Pentium Pro had fewer transistors than the 21164, slower clock rate and yet it had a competitive specfp and higher specint (!!).
What is the accepted explanation for this ? I figure it is the OoO which obviously favors integer code.
However: Why did a OoO implementation of the x86 ISA need fewer transistors than an in-order implementation of Alpha ? Am I misreading the numbers (e.g. most of the transistors in teh Alpha could have been in the L3 cache, etc) ?
I am not implying anything - I am truly curious.
