>It blows the 386 out of the water

For certain values of "blows out of the water". But the points I was trying to make are repeated in the article you reference:

>RISC processors couldn’t tap into the huge, non-portable software installed base except under emulation

That is, they ran slower.

>This allowed the Pentium Pro to reach a clock speed of 200 MHz

The simpified die design did not, at expected, allow the MIPS machine to clock faster than CISC machines

>The Pentium Pro combined an innovative new out-of-order execution superscalar x86 microprocessor

Those were the compiler ideas which were the other half of how RISC computers started out faster than existing CISC computers.
