A good way to measure CPU performance in a CPU-agnositic way (not sure if thats the right phrase to use) is instruction-count. you would have to disregard things like cache when looking at instruction count, which is probably bad, but it serves as a good CPU measure.
- fijal 14y agoNo, it's not good at all. Cache stalls can easily account for 1/2 of your processing time. On top of that you have CPU pipelining and multi-issue CPUs. It was a good idea a while ago, now it's really not that great.
