- I Sun has just announced some new workstations based on
- a microSPARC(tm) chip running at 50MHz and producing
- 59.1 MIPS. I know the problem with MIPS but
-
- How can a non-superscalar implementation at 50MHz run 59.1 MIPS?
- I thought the holy grail of RISC was 1 instruction retired per cycle
- and that this is never attained (much less exceeded) in a non-
- superscalar implementation.
-
- MIPS is probably the most misleading term in the field but
- what on earth can they mean?

- I can neither confirm nor deny that these questions
- are interesting to anyone else.
