Hi Roy! :-)

The AMD 5x86/133 uses a different CPU core than AMD's other 486 chips. The
"P75" is meant to indicate that the application performance of
the chip is roughly equivalent to a Pentium running at 75 MHz.

Yep, puts a lot of additional burden on chip design because at such speeds,
you have to be careful that stuff like the different bits on a memory bus
interface have very similar ways to travel, otherwise you're going to have
all kinds of interference and different bits arriving at different times.
