- Well it is only a change in clock, but its not simple math. Various factors
- contribute to how well it will actually perform. I know at NekoTech, they
- had tested the 275 MHz systems at various frequencies and the change in
- performance was definitely not linear.

- Ah, but you miss the crucial point! Digital, in its infinite lack
- of wisdom, has (IMHO) killed the momentum of the AXP by placing a
- MAJOR price premium on the 300MHz 21164. For the extra few MHz, the
- 300 part cost close to $2K more than the 266. Digital has told me that
- the new 21164a "shrink" part is supposed to be faster and cheaper,
- but the latter remains to be seen.
