wbmw,

They'll put the benchmarks up on big banners and wave them around both forums and claim how poor the performance of the Pentium 4 really is - and how Intel should be condemned for calling their chip 2GHz. Personally, I don't see the usefulness in an application that is so far removed from real life that it had to be pain-stakingly engineered to do what it was designed to do.

I don't think there is much disagreement that P4 perform poorly on code that is not in the trace cache, well on the code that is in trace cache.

I agree that this type of test is not that useful for real life, since it is totally synthetic. But if the decoder is in fact half speed and Kap can prove it with software test, the test would be worthwhile, and anybody interested in PC technology should welcome it.

I have no idea how I would go about what Kap is trying to do, but some insight can be gained timing some code with with trace cache ON / OFF - if it can be turned off, which would simulate some of what the routine would do.
