While we're discussing rumors, I've been told (by someone I'd _expect_ to know) that the 68040 has roughly the same integer throughput as a SPARC at the same clock speed. Anyone out there have some hard data on this? Also, with the 040 trapping, then executing software routines for trancendental functions, I'd _expect_ at least the trancendentals to be computed slower than a Weitek or 882, in spite of the PR. Has anyone benchmarked this? Does Moto have plans for a faster (perhaps trancendental-only) version of the 882?
