[citation][nom]Cryogenic[/nom]My biggest issue with CPU's is not their prices right now, you can get a decent CPU for 200$, which is fine, my issue with CPU's is their power consumtion , I really like if max wattage would stay bellow 65 Watt and not up to 125 Watt, like it's happening right now.Prices are fine, wattages are bit high.[/citation]
It's a matter of yields. Don't forget the Core i7 uses a different method to communicate other than the old FSB and it also has a built-in memory controller. In the old days you weren't taking the memory controller power usage into account. (I don't know what percentage it uses within the CPU though). But in general, it's just that the design is new, and it will get better. I would expect 95w Core i7's in maybe three months.
And even then, now they are advertising these parts at 125/130w to get all of them under the same ceiling. Some of them will actually be, in practice, 95w parts.
My E8400 revision E0 is rated at 65w, but I've read in another site that it hardly ever goes above 39w. They could easily rate these at 45w if they wanted. They probably won't so as the margin to quad cores won't be so visible. More people would eventually stick to the Dual Cores in order to save energy.
If you look at the different processors you'll see that a Pentium E5200 running at 2.5 Ghz has the same TDP as a E8600. They're both 65w, 45nm parts, yet the E5200 only has 2 MB of L2 cache versus 6MB for the E8600, and an FSB of 800Mhz compared to 1333Mhz for the E8600 and a core clock of 2.5 compared do 3.16 Ghz for the E8600. They're not in the same power consumption league at all, despite the same TDP. And now there are even quad cores rated at 65w. Expensive, but they are here.
