P4 vrs Opteron Performance

I've been running some numbers on P4 vrs Opteron performance and I don't think AMD fans are going to like this.

First AMD's estimated SPEC Scores:

3400+ Opteron with 1 meg L2
Int 1202
FP 1170

If these are Peak scores then the base numbers will be lower.



Intel has recently released SPEC scores using 1066 RDRAM

Select "Performance" under "Tool"

2.8GHz P4
INT 1032
FP 1034

Both are Base scores.

Now I am going to allow for 100% scaling because I believe HyperThreading will allow for at least 100% scaling over the 2.8GHz non-HT P4. Additionally there may be an additional change to come that will have a positive affect on performance as well. So I get Base scores of:

3.06GHz P4 HT enabled
INT 1127
FP 1133

3.2GHz P4 HT enabled
INT 1179
FP 1181

Considering that the estimates posted by AMD are for the 1Meg Opteron, and if they are Peak scores rather than base, I believe I must revise my estimate and say that it is very possible that the soon to be released 3.06GHz P4 with HT enabled will outperform not only Clawhammer as I have been saying all along, but Opteron as well. Additionally if AMD's scores are not Peak which I suspect they are, the 3.2GHz P4 with HT enabled will match Opteron to an almost dead heat. If they are Peak then the P4 will clearly win.

And in the middle of next year when AMD's processors are just starting to ship, then comes Prescott...
