Are programs like SISandra 2002 just speculating performance of cpus that they have not actually got any data for, I can only tell you that when I benchmarked the P4 3.06 GHz a while back, the scores vs. XP3000+ were damming to say the least.. Which can only lead me to believe SiSandras benchmark reference system was a very poor performer or is not accurate.

Is it possible there is TB 3000+ with lower cache etc which just doesn't do as well .. doesn't seem likely eh?..

What of the technical issue of two processing units vs. one also probably has allot to do with it, you can really see that the two processing units help particularly with cpu benchmarks I guess for load balancing reasons, switch the affinity to 1 cpu and you tend to loose a bit of performance, but gain much performance on things like memory bandwidth tests.

I believe AMD can not hold there current rating scheme in play.

Sorry about the last post, that wasn't supposed to happen.

I think that this review is biased because the sse2 instruction set taken into account during sissoft is throwing real world computational power out of proportion.

An athlon 1.4ghz is roughly equivalent to a pentium 4 2.0ghz. I'd be willing to bet the 3000+ runs close to the 3.06 that this review made it out to be. Probably beating the 3.06 on some benches...

Here is a link where they say they have evidence of the bias:
