Core i7 965 @ 3.2GHz (133*24) - $999
Core i7 940 @ 2.93GHz (133*22) - $562
Core i7 920 @ 2.66GHz (133*20) - $284


ASUS Rampage II Extreme - $398

For a list of triple-channel DDR3 kits, i4memory has it.


This makes me cry that the current Core 2 Duos/Quads bottleneck SLI/CrossfireX so much. You get 40+ FPS more from a Core i7 T.T

I'll take my chances with a Quad, thanks.  Who wants to spend ~$800 for +1 FPS in Crysis?

bench marks are against a q9770 so who wants to pay $1100 on a quad for 1 fps less? when they can spend $800 and get at-least 1 fps more

also thats just one game, the 20 to 40 fps more in other games I guess don't matter, some people want to judge i7 only on one thing.

also the chart gamerk2 has posted is not from the same place that skyR has posted, which has a different results then the one gamerk2 has posted.

also according to gamerk2's screenshot in crysis i7 is only 1 fps higher, where as if you look at skyR's screenshot you will see the i7 with the turbo off has actually 13 fps more then qx9770


also the site gamerk2 used the screenshot from, used a 1066MHz memory,


you get that? they used a 1066MHz ram with a chip that has no FSB so you can use a higher ram, but no, it was 1066, one of the chips biggest changes is that it no longer uses FSB so you can use higher ram, and we are suppose to judge i7's performance based on 1066MHz ram.

I don't think so, skrR's test was done with 1333MHz ram and even that does not show how well i7 can do, the true test is to use a qx9770 with highest ram it can handle and i7 with the highest ram it can handle then you would see the true difference.

so if you want to know one difference of why skyR's shows a different fps then the one gamerk2 has listed is because gamerk2's site, in order to make them look closer did not use the full potential of i7's ability by using ddr3 1066MHz ram, vs skyR's site that used 1333MHz ram, now imagine what could have happened if they used a 2000MHz ram with i7 which is something that is the i7 can easily use and is build for.

anybody wants to know what the difference is, untill you see an i7 with 2000MHz ram and its own mombo and itw own ram put next to qx9770 with 2000MHz ram, you are not seeing the true difference.

until then take all of these reports with a grain of salt. cause so far none of them show the true potential of i7.

I also like to point out that I'm not saying that gamerk2 did anything wrong here, my problems is with the site he pointed out and not him all, he is just posting results, so my comments are not directed at gamerk2 himself at all, they are pointed at the site he is pointing to.

Actually, in defense of nehalem (im not biased Broken%20Heart ) it comes out ahead (hard) in sli/xfire configs which are cpu bound.
 
So if youre building a game/bench-crushing rig, nehalems extreme edition should be on top of your "to get" list.
 
Im happy that ive decided to wait after all.

When is DS releasing their i7 findings?  on Nov 17 we begin waiting for 32nm technology. The cycle never ends. When will we get the 80 core cpu that intel showboated in 2007?

Not possible. The 965 has an unlocked multiplier and unlocked TDP.

Both the 920 and 940 have a locked multiplier of 20 and 22 a long with a TDP lock of 130W.

I've seen a 920 @ 200 * 20 but I doubt that is going to be very common...

In simple terms, the multiplier determines the speed of a component. Each component has it's own multiplier.

In this case, a Core i7 920 has a reference clock speed of 133MHz and a multiplier of 20 (133 * 20 = 2.66GHz) while the DDR3 ram has it's own multiplier which might be 8 (8 * 133MHz = 1066MHz).

This is for the 920 and 940 models.
The limits hard-wired into the core are 100 A and 130 watts.




So what exactly is the point of this then?

Point of what?

Intel Dynamic Speed Technology is the new name for Turbo mode. It automatically overclocks your CPU when it is not using all four cores.

I see its max mp at 20, thats as high as you can go on that chip. Dunno what youre asking about.

The point?

The point is Intel wants you to buy an expensive chip if you want to OC. They dont want you to buy a cheap CPU and overclock it to have it match the performance of more expensive chips out there.

So the days of buying a 200$ CPU, overclocking it and increasing its performance to match CPUs in 700$ range are gone. (Example)

Those might be engineering samples or some reviewers are misinformed.

But what it does is if the 920 or 940 hits the 130W wall, it'll start to throttle it's speed.

Ya i know this as well.
All i know is that i am pretty pissed with intel at this point. Taking complete advantage of the situation not allowing them all to overclock as much as they can. I really hope that amd will come out with something amazing. Otherwise spending $1000+ for a unlocked chip will be completely ridiculous.

What would be nice is if a Mobo Manufacturer found a way around this limitation. I doubt its possible but i hope it happens.

I'd put my money on that the most common overclock for the 940 will be no higher than ~170*22 (3.7GHz).

same for the q9650 on air, but then common OC is not what most people do, also lets wait and see what it can do. I have a feeling it will oc higher.

but it costs less then q9650

Yes the chip itself does. But not the mobo and ram. Now i know you can use slower ram. But who wants to do that?
