OK. In regards to my comment:

Wait, what are you saying? IPC is Instruction Per Clock (Cycle). It has nothing to do with CPU Frequency whatsoever. Or did you come up with "Instruction Per Core"?

I posted this after you mentioning "~25% better per core performance" (when it should be per clock, per core would be 10% higher) and pulling Turbo mode in.
Your logic is sound, I can give you that.
A few issues, though. The biggest one is that you're taking the numbers from the slide with some relative rating which will not necessarily be absolutely true. The second one is that you're going for the maximum possible penalty, and that might not be a very good indication (especially when it comes to a marketing slide and we have no idea what benchmark was used).
Let's hope you're correct, though!

Regarding the IPC improvement and why I doubt it's going to be actually true...
Single threaded Cinebench is a good indication of FP performance, right?



If your 56% calculation is correct then BD @ 3.2GHz would score 3951*1.56=6164, which is [(6164*31/32)-5405]/5405 = 10% faster than SB clock per clock (single threaded FP workload). It wouldn't be just on par with Westmere, it would blow away SB by 10% (which is more than the difference between two generations of Core i7). Which is pretty crazy if you ask me.
