I've got a few numbers from the wikipedia, but most are of "modern" CPUs
I know about the issues that comparing MIPS present, but I don't think
that there are many ways to compare computers from the 80s.
Anyway, I did some BASIC tests, and came up with some unexpected results
FOR to 10000 A+1 to 5000 ? “A”*1000 Goto next 5000 Gosub IF/THEN
Average
Tandy 1100 7 10 21 5 7 10 10
CoCo2 Poke 11 18 7 8 11 30 14.17
CoCo3 Poke 11 16 15 9 13 24 14.67
Vic-20 13 42 20 9 14 32 21.67
Apple //c 13 31 21 10 13 32 20
CoCo2 15 24 10 11 15 40 19.17
CoCo3 22 31 31 19 26 47 29.33
Atari 800XL 24 26 20 20 25 22 22.83
Model III 27 38 24 21 29 36 29.17
Model 100 32 39 50 20 24 36 33.5
Surprisingly, the high speed poke turns a sluggish CoCo into a PC killer
(The T.1100 laptop)
The poor rating on the Print test for the CoCo 3 is because I used one
of the hi-res text modes.
But anyway, the CoCo3 seems slower than a 2. Might be because the 3 is
always in "all RAM"?
