Intel Core i7 Processors: Nehalem and X58 Have Arrived

18 thumbs up

On the surface, Intel's new Core i7 processors look much like their predecessors, but the new architecture and socket obviously results in some major differences between the two. What you see pictured here is a Core i7 920 processor...

 

The new Core i7 processors are similar to Core 2 processors in that they have a similar looking heat-spreader and packaging material, but the similarities end there. Core i7 processors are physically larger than Core 2 processors, they have significantly more pads and surface mounted components on their underside, and there are pads on the top edge as well. Whether or not those pads on the top side of the chips can be used for some interesting mods remains to be seen.

 

In these side by side comparisons of a Core i7 and Core 2 processors, the differences between the two can clearly be seen. The Core 2 processor is noticeably smaller, and the density and number of pads on its underside is obviously reduced.

Intel Core i7 Extreme 965 CPU-Z Details

We fired up the latest version of CPU-Z to give you all a glimpse into the Core i7 platform’s inner workings, with a Core i7 Extreme 965 installed in an Intel X58SO motherboard. In its stock configuration the Core i7 Extreme 965 processor powering the platform is clocked at 3.2GHz (24 x 133MHz, 6.3GT/s QPI link speed) with a 1.16v core voltage. The process technology is correctly identified as 45nm and the processor uses Intel’s new Socket 1366 LGA packaging. The processor cache configuration information and QPI link speed are listed as well.



Intel Core i7 Extreme 965 Processor Overclocked to 4.1GHz

We also did some overclocking to see how much headroom these early Core i7 processors have left untapped under their hoods. Because the Core i7 Extreme 965 has its overspeed protection removed--i.e. its multipliers are unlocked--we overclocked the processor by raising its multiplier to 25 and also experimented with an increased QPI speed. With the core voltage raised to 1.4v and the memory voltage tapped at 1.65v, we were able to take our particular processor up to a stable 4.15GHz with air-cooling.

As you may have heard in the weeks leading up to today's announcement, the Core i7 processor, and in particular its integrated memory controller, are sensitive to increased voltages. Memory voltages higher than 1.65v are not recommended and could damage the CPU. In light of this, memory manufacturers have begun shipping triple-channel DDR3 memory kits capable of relatively high frequencies with voltages no higher than 1.65v.

Wow way to give me the upgrade bug. Not only show off the i7 CPUs but the new version of my mobo too.

I'm going to handcuff myself to my chair for the next six months (maybe AMD will somehow surprise us with something that drops the prices), then buy buy buy!

ICE make me feel obsolete

 

If you 2 guys get the upgrade bug REALLY REALLY BAD and you dont have a need for those 2 Monsters that you have, I got a home for the poor old wore out and out of date Rigs you have now right here. Its kinda like a recycling center! Here,s my address Amdcrankitup,s house and if it will help I,ll pay the shipping for you so you wont have to take the money out of your I7,s savings.Thats the kinda guy I am always trying to help! LOL

Oh amdcranckitup. Not sure if I'm getting a core i7 this year or not, but you know that you guys would have first dibs on anything I stop using.

 Im just messing with you BOB.Im so impressed with the rigs you and ICE have I cant even think that far ahead to be able to get an i7.But give me time and I,ll get up to a Quadcore first of the year and maybe even a Striker or Maximus with a 9800 thrown in there some where. That would get me closer and I would be satisfied with that setup for a while. Like to see one of you guys get a i7 rig just to se the reveiw posted by one of our guys here! Maybe Raid will get one soon he,s the one wih the money around here! LOL How bout it Raid have,nt heard from you much lately.He must be reving up one of his current Hot Rods he,s got and going to spring a suprise on us!Geeked

Lol Well I sold my old rig which was no slouch to a girl at work and since then I have reinstalled windows on it 2 times, put a new hard drive in it and I got a call tonight saying it wont cut on at all now. I still have not got a dime for it. So if its something like the PSU or mobo I'm going to just pick it up and say that I can't fix it. It's has worked fine for me since I got it and now in a few weeks it just keeps dying.Hmm I'll see what I can get out of it you guys having first dibs of course.

  Thats how it goes when you sell it to some one you know its suppose to come with a lifetime warranty!!  Or at least they think it does. On top of that she has,nt even payed you. Most of the time when they have a problem its Usually operator error not the rig.

Yeah I never had a problem from it.

Awesome. I can't wait to build an i7 system...unfortunately I'll need to wait a bit longer before upgrading though.
