- MIPS: Meaningless Index of Processor Speed. Someone here wants to get a
- Sparc-10 Model 30, and gets all hyped up about the 86 MIPS figure that some
- greasy salesman quoted him. I patiently explain to him that his application
- performance will be more realistically modelled by SPECint92: 44, or around
- twice the performance of a Sparc-2.
-
- Thank you to the SPEC people for devising a benchmark which reflects real
- performance. Thank you to Sun for breaking the SPEC figures out in product
- announcements. No thank you to greasy salesmen (not Sun in this case - an
- electronic CAD tools supplier who also packages Sun equipment) for quoting
- MIPS to the uninformed.
