Sorry if this has been brought up, i'm struggling to follow this thread now!, but If you look at the 50% higher performance claims as a fully utilised, 4 Module - 8 module CPU, then shouldn't single threaded performance actally be a strong point? since a single core processing a thread isn't sharing the front end, nor the cache?

The statement that performance "scales 80%" from 1 core, to 2 cores in a module kind of proves this point.

This also makes any "12.5%" IPC per core calculation wrong.

I asked this quesiton earlier, (I think) but I'll ask again. Does anyone know how 4 threads are handled by the OS on a 4 module - 8 core BD?
