The settings I was told to use put me at CAS 2.5. It sounds like you don't really know what configs Intel uses for SPEC testing. >How would this be 'fair'?

My point was that SPEC is not biased, because the vendors are submitting their own scores. >slow. I went and 'rented' one myself.

You get a 29% improvement in Gzip vs. a 22% improvement. How do you explain this? You're obviously a big AMD fan, why should I think your results are somehow more accurate than results from the companies themselves? -Tom
