If you have access to a Usenet node, look in net.micro.68k for a set of benchmarks run by the University of Rochester comparing the 68xxx family with the 80xxx family. It shows relative performance for several benchmarks (the ones from EDN) written in assembly for each processor. In each benchmark, the fastest cpu was rated 1.0. The only benchmark that the 80386 outperformed the 68020 (with cache enabled) was the string manipulation benchmark. In that one the 80386 was 1.00 and the 68020 rated 1.02. In all the rest (bit manipulation, indirect addressing, qsort, etc) the 68020 rated 1.00 to the 80386's 2.nn or greater! The overall average showed the 68020 at 1.02 and the 80386 at 1.89. Timings in seconds were also posted but I don't have them handy. If anyone is interested I can upload the article. Rick Schaeffer
