LOL, literally no one said that in regards to C2D vs P4. Not one single person. RKL is a step back because it is a process backport of an architecture that got tired two years ago. It is a step back because it made no attempt to be energy efficient, instead cranking on voltages for extremely diminished performance returns.Wrong. C2D was "technical" step back in clock versus P4, yet it was irrelevant as C2D was faster.
Like I already said, pricing is the only viable play.
As for how many cores people need... guess what? The AMD 4 core solution is still far superior.
