Well those C10 numbers show i5 @2.66 being approx. one bin faster than i7@ 2.66Ghz. The only reason could be turbo boost being higher than on i7 part.i7 920 should do ~2793Mhz ,if not more, in single threaded apps.Originally Posted by JumpingJack

Maybe the Uncore speed. I guess the uncore is OCed on the Lynnfield. There is a bunch of unknown values. Did Turbomode kick in or not. Did it exceed the TDP value define in BIOS etc etc.

Crunching for Comrades and the Common good of the People.
Anand has mixed his cinbench results before, Scientia wrote a complete article inferring the incorrect conclusion because he was comparing 32-bit to 64-bit runs, I shot him an email I will see if he can provide an explanation.
32-bit single threaded, for example, I only see +1x bump
This is because windows scheduler is distributing the load across all cores (real and virtual).

Thanks to the BCLK @ 166Mhz the core i5 was probably running @2822Mhz when the turbo mode was active, and that could explain why it was faster in some benchmarks.
I think it has more to do with it than that -- using Bclk and nothing else OCs the memory and NB, the latter being more important for performance in these simple benches.
