K10 slower than C2Q in Cinebench, clock for clock!

do u know 100% shure that cache doesnt have a huge impact on k10.
and do u know for shure that this 1.6ghz version has 4x128kB L1, 4x512kB, 1x2048kB L3

We've known with previous versions of K8 that cache doesn't have a huge impact on performance. Perhaps 2-3% on average between 512KB L2 and 1024KB L2. This is strictly my opinion, but I believe the quad core is going to need good bandwidth and a darn good cache prediction to be effective at keeping all four cores munching on data.
