The way I see it (correct me if I'm wrong), is that the Core i5 has 4
physical cores, Core i7 has 4 physical cores but reports 8, FX-8150
has 8 integer cores (and 4 floating point cores).

Anyway, the Core i7 seems to greatly outperform the Core i5 in many
benchmarks. What are the reasons for this? Is it because of the way
that it reports another 4 cores to improve SMP? Would performance be
similar if the feature were enabled in the Core i5?
