Intel's Core i7: Blazing Fast, But Crippled O/C

[Guest]

Hmm you still have not updated the cpu's power consumption chart. This chart only shows the consuption of the cores but not of the uncores region.

LostCicuits and HardTech4U already updated their article weeks ago.

Is turbo mode the same as overclocking?

 

[natesuniverse]

Yes turbo mode is basically an auto overclock function of the cpu in this case.

"The fastest Core i7, the 965 Extreme, is more than 2.6 times as fast as AMD’s current flagship CPU, the Phenom X4 9550 BE."

And cost 5.9 times as much.... (I7>$1012 v AMD9950>$169 @ Newegg)

Amazing we compare a processor that cost almost 6 times as much and jump up and down about how much it beats the cheaper one. Not trying to bash here just to keep things in perspective.

[citation][nom]V3NOM[/nom]"The limits hard-wired into the core are 100 A and 130 watts" HOLY CRAP 100 AMPS! can a power supply even deliver that kind of power? 12v rails of like 18v are common...[/citation]12v rails? 18v? A processor doesn't need 12v and sure as hell doesn't need 18v, they all run at around 1 V
P = U x I
P = 130 W ; I = 100 A
U = 130 / 100 = 1.3 V

I did some analysis on the above, and current UK prices as of Jan 18th 09. Compared to a E8500 the performance gain/loss of the other CPUs:

Virtually all so called new processors since the pentium 3 are useless with Virtual studio technology.
CPU usage climes upto 75% when completing the most simple task in music production. Operating more than one VST instrument seems to be near impossible for today's processors. All these Hyper Threading do nothing better against a simple "Singe" powerful processor. I have owned 6 PC and laptops to date and not one of them can cope with studio applications. Everything seems to be visually focused in the development of these processors. And worse is the developers who make the PC's with them because they are all "Game" or "Business" related systems which shows where the processors are aimed. They can not cope with ONE single Echo chamber without overloading. Useless!!
