FYI: Wikipedia lied. But at least they had the decency to make up some new numbers. :lol:
Wikipedia also says that Wikipedia is never to be considered a reliable source of information and cannot be treated as an authority on any subject whatsoever.
According to:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC68060 "The MC68EC060 offers superscalar integer performance of over 110 MIPS at 75 MHz".
In Motorola tests the secondary operand execution pipeline was used in 50% to 60% of instruction pairs.
Branch prediction isn't free when it takes the branch. It doesn't have a horrible penalty for flushing the pipeline when it guesses right, but it still counts as an instruction. Motorola claim over 90% success rate.
You can't get over 160mips at 80mhz and to even achieve that your code would have to fit into the 8k of cache, not do any moves from or to memory, it would have to perfectly predict every branch & your code would have to be very specialised to utilise both execution units on every instruction.
