Simon system is running at 50 MHz, may be should be
more appropriately designated "dx2-100", while "dx4-100" most often
imply bus speed of 25 MHz (or sometimes 33 MHz).
The real bus speed may make a lot of difference, e.g. memory
transfers 32-bit benches about 45-50 MBytes/sec with dx2-100.
Drawback is SIMM and other components got to be able to match

No, DX4-100 ALWAYS means it's a clock-TRIPLED chip.  It has a 33Mhz
bus.  No one sells a DX4 chip that is clock quadrupled.  Stupid Intel
started the DX4 thing because they couldn't copyright processer
numbers so they called their DX4-100 the IntelDX4-100.  But it's NEVER
been a clock-quadrupled chip, always clock-tripled.

I thought that the AMD chip could also be run as a DX2-100 (ie
50 MHz external, 100 MHz internal).  This would be good if your
cards can handle it.
