- You subtracted when you should have been dividing. So your list should
- have read:
-
- 61 times faster than an Amiga A4000/040/25
- 6.1 times faster than a Pentium 90
- 2.0 times faster than a Raptor IIA (Alpha 21064A/275)
-
- Or, if you average the two results:
-
- 50 times faster than an Amiga A4000/040/25
- 5.3 times faster than a Pentium 90
- 2.0 times faster than a Raptor IIA (Alpha 21064A/275)
-
- That's still pretty quick, though.
