ok, so the C2D MBPs went all the way up to 3.06 ghz, and the 2010 MBP 15/17 went all the way up to a dual core i7 at 2.8 ghz, and now the fastest is quad 2.3 ghz. Yes, I'm aware that clock speed isn't everything and that performance has gotten better each generation. I'm wondering why does the clock speed always seem to go down each generation? Why couldn't Intel keep the i7 at 2.8 ghz for sandy bridge? and btw, does anyone know how many stages the current sandy bridge pipelines are?
