It would be interesting to see numbers from some less beefy OOO cpu (like pentium pro or cortex a9). The tested processors take the OOO to extreme lengths. edi

It would be interesting to see numbers from some less beefy OOO cpu (like pentium pro or cortex a9). The tested processors take the OOO to extreme lengths. edit: there's a graph in http://www.engr.colostate.edu/~sudeep/teaching/ppt_554/lecture07-ilp_limits_tlp.pdf http://www.engr.colostate.edu/~sudeep/teaching/ppt_554/lectu... that shows ARM A8->A9 speedup around 20% on most SPECint benchmarks, and part of that is from other improvements besides the OOO.
