David,
From the chart above it looks like a Pentium 90 is 10 times faster than
an Amiga and an Alpha 21164/300 is 60 times faster than the same Amiga.
This means that the Alpha is 6 times faster than the Pentium 90! The Alpha
21164/300 is 2 times as fasst as the Alpha 21064/275. Of course this is
only my interpretation of the data presented above.
