- So, the desktop Alpha is more than twice a Cray-1, and 7-8% of a C90.
- Of course, this comparison is unfair: both the C90 and AXP have
- virtues that the Linpack benchmark doesn't measure. However, Linpack
- is *the* benchmark which has been run on all the big parallel
- machines, so these numbers are relevant to the parallel machine that
- Cray is building out of Alpha chips.
