[HECnet] SIMH VAX memory weirdness

[hvlems at zonnet.nl]

The VAX ran at slightly lower speeds than a Pentium I at the time. Its performance got higher performance marks. Both are CISC designs that makes them comparable but the VAX instruction set was very rich and designed for 32 bit address space. The Pentium showed its heritage there (and possibly still does). I do wonder how a VAX cpu made in a current technology woulld perform.

Still doesn't run as fast as a 3 Ghz NVAX processor. Oh wait, that was only in my dreams....
(did some rough-as comparisons a while back and came to the conclusion that Intel Core Duo and VAX processors were roughly the same performance Hz to Hz).
