Oh, just get over it already. Phenom II's have a better IPC than FX's, everyone knows that. But look at the benches, Piledriver has a much higher clock than the older architectures, even at stock settings, and better performance as a result. Yes, it is a bit less efficient clock-for-clock, but it compensates with a much higher clock at similar wattages, so it is better.
This discussion came up when Bulldozer came, and it made sense back then, with clocks in the 3.6GHz range (similar to the 965BE), but now they are mostly around or above 4.0GHz, which is the sensible limit of a Phenom. "But a Phenom can reach 4.2 on air!" And an FX-4350 reaches 4.7.
Piledriver has become better, Steamroller will be even more, and old processors are old. Just move on, please.
