wbmw,

According to my calculations, and based on the score of 2200 on a system with 8 cores, the clock frequency would have had to been as low as 1.6GHz. This is well below even the HE Opteron, which clocks as high as 2.6GHz.

Good point, but if Barcelona only clocks at 1.6 GHz at 65W, and they wanted to make a comparison at the same clock speed, that's what probably lead to the selection.

But it's all a little weird, because if they wanted to make the comparison at the same power, they should have used the fastest Opteron at 65W, which, as you say, is 2.6 GHz.

Or, if they wanted to make the comparison at the same clock speed, why choose much slower speed, compared to expected launch speed?

What is concerning though for AMD IMO, is limited to non-existant IPC gain over K8...
