Core i7 965 XE Races Through to 4.20 GHz
It's high time to break the dogma. Core i7 965 Extreme, Intel's next generation flagship desktop processor based on the Nehalem architecture, does indeed overclock satisfactorily. IT OC Taiwan overclocked the chip, which sports an unlocked FSB multiplier, to a respectable 4.20 GHz, at a FSB speed of 200 MHz, and multiplier value of 21.0xFSB. A vCore setting of 1.72 V was used, which is above the danger-mark, taking Intel's own warnings into account. The CPU was aided by dual-channel DDR3-1600 memory operating at timings of 8-7-7-24. It provided a tested bandwidth of close to 16,000 MB/s. The CPU took 3DMark Vantage for a spin, with 3596.76 plans/s in CPU Test 1, and 32.87 steps/s in Test 2. The chip used in the attempt was an engineering sample.

If the slowest i7 core able to OC to 3.2GHz and with voltage under 1.3v, then I think it's already too good to kick AMD ass.
And according to the Vantage CPU score, Nehalem prove to be faster than the current QX ~25% clock vs clock.
We do not need Quad-core 4GHz for gaming, and I don't think there are many people like to run their CPUs 24/7 with a voltage over 1.4v
Dude, that thing would probably explode with all those volts!!!
And this is extreme version with unlocked multi, i wonder how the lower chips will do?
Link.
I can understand why you think so, but let's me tell you something, which games at this moment can fully support 4 cores and 8 threads?
Also I wonder about the stepping, if this is an unfinished stepping the results may be less than at launch. The denab has been show at these speeds, if they have closed the clock for clock gap then those may actually be closer than amd has been in a while (since before core 2), at least w/ apps that don't utilize 8 threads (most of them). And I would wager those come in at much less than $999......
sorry guys, im not very well informed about these things, but I heard before dat the nehalems no longer uses FSB but instead something called quickpath. Alrite, but why was FSB mentioned here though? is there something im missing here? :banghead:
thnks guys.
No Wolfy is getting 16000, and 26.4 Lat. If you cant use that then stick with your Benchmark Game and clock till you drop. The X48 and p45 will be around for awhile ,though they are getting stale.
With 1.7Vcore I guess this baby is running HOT HOT!
AMD has had their HyperTransport since 2001 but it has always been called a FSB so it is the same thing here.
Bus speed x CPU-NB interconnect multiplier = Interconnect speed
Example: Let's take Phenom X4 9750
200 MHz x 12.0 = 2400 MHz (clock speed)
200 MHz x 9.0 = 1800 MHz (HyperTransport link speed (equals 3600 MT/s))
Now, your altering the bus speed, affects both the clock-speed and interconnect speed. End of the day, the interconnect (HyperTransport for AMD K8 onwards, QuickPath for Intel Nehalem onwards) handles data transfers between the CPU and the northbridge.
2. WTF 1.72 volts, kill me now.
3. Multi surprised me. Alot. 21x wow.
Anyway, interesting offering to say the least. I think I might wanna do WC'ing if I go this route.

and oh yes, G200 are utter failures, for the pathetic performance with transistors and die size like those
That's sad.
And BTW, if that's real, apparently you missed the other 5,000 games that the geforces excel at.
And at that res (that no one will play at or use AA), it just makes it even more irrelevant.
Besides, this Nehalem is running at 4.2GHz, it's altogether possible it only takes 1.6V to hit 4GHz. It takes huge voltage increases to get a few MHz when you are reaching the limits of a cpu. I'm willing to bet a 4Ghz Nehalem will easily outpace a 4Ghz Deneb in just about everything.
But at any rate, like I said in another thread, if this is indicative of what we can expect from the retail chips, it looks like I'll be sticking with my QX9650. I'll just pick up 2 new DDR3 boards(one Xfire and one SLI board), a good controller card, some DDR3, and ride it out until 1366 cpus clock better. Under DICE cooling, the QX9650 should be able to clock far enough to overtake the Nehalems.
*cough*
Obviously, CPU-Z has no clue about the actual vCore...
*pokes people with a pointy stick*
