Sure can and they would be the QX9650 and QX9770 (Which wont actually be released but makes intel look good)
Clock for Clock the 45nm chips really arent that much better. The extra cache may help in some programs and im sure it will be a nice upgrade for some but IMO not enough of a reason to sell a gift of an already awesome laptop
I know what im talking about when it comes to computer hardware and yes your partially correct in saying that I would be better in those forums but you dont have to be rude about it.
Now please stop hijacking this thread.
Well see here is your problem. We are talking about the Mac Pro which is a desktop, not the MBP which is a laptop.
As the Mac Pro if updated would be moving from dual dual-core Woodcrests to dual quad-core Harpertowns. That is a significant difference. Double the cores and quadrupling the cache, faster clock speeds too.
Now if we are talking about moving from a current C2D notebook to a 45nm C2D notebook, sure the difference isn't terribly significant. However that is not what we are talking about.
So it would appear that you don't know what you are talking about when it comes to computer hardware. Try again.
