I realize it's pointless arguing, but assuming you can utilize all cores, the scaling factor by adding cores is typically in the 80-90% range. Proof: Cinebench R11.5 single-threaded score for 1100T = 1.11, multi-threaded = 5.9. 1.11 * 6 = 6.66. 5.9 / 6.66 = 88.5% scaling, for SIX cores. So, how much clockspeed would it take a single 1100T core to match all 6 at 3.3ghz? Well, 1 core at 88.5% * 3.3ghz * 6 = 17.52ghz single-core.
Cores SCALE, not at 100%. Don't bite someone's head off because they're off by 10%.
So, some simple reasoning...
Take a Core 2 Duo, at perhaps 3ghz. OC it to heck, maybe you hit 4ghz and now you're in the 125W + power consumption range. Compare the 4ghz C2D to a Core 2 Quad at 3ghz - which one has more total performance? And uses less power? To both, the Core 2 Quad.
