From the currently best available SPEC benchmarks:
The DS 3100 is: 11.8X faster than VAX-11/780 on 4 SPEC integer (geometric mean)
10.9X faster ... on 6 SPEC FP
11.3X faster on the entire 10-benchmark mix (SPECmark)
These programs have little I/O or kernel time, os these are CPU benchmarks.
The least ratio is 9.5 (spice) and the greatest is 13.2 (nasa7).
The Sun SS1+ has a published SPECmark of 10.0; I don't havethe individual
numbers, but I'd expect it to be about equal on integer, and somewhat
slower on FP. (Based on clock ratios from SS1).
The benchmarks are big enough to thrash the caches around at least some;
which gives the 780 a fairer break. [Small benchmarks fit in most RISC
caches, and so they go faster than a VAX relative to how they do on more
realistic ones.]
