Yorkfield @ 4140MHz on Air, New World Records
The guys over at Nordichardware got their hands on the latest Intel Core 2 Extreme QX9650 12MB L2 Yorkfield CPU, trying to overclock it using both air and LN cooling. The result is 460MHz FSB and 4140MHz stable clock frequency achieved with ASUS P5E3 Deluxe motherboard, all air cooling. Using liquid nitrogen, the same QX9650 CPU goes up to 5600MHz, breaking all SuperPI and 3DMark 05/06 world records. The new world records are now 37,095 points in 3DMark 05, 27,542 points in 3DMark 06 and 8.110s in SuperPI. The benchmark system consists of ASUS Maximus Formula R.O.G X38 motherboard, paired with Mushkin's fastest Redline DDR2 running at 4-4-4-5 timings with a 4:5 divider and two ASUS Radeon HD 2900 XT video cards (1120/980MHz).

Am I an AMD fanboy? Sure. Did I say anything inaccurate? Hardly.
just my .002 :P
Turn the tables and I believe intel would be down for the count, since they've lost what innovation they once had (which was many yrs ago).
We, clearly, can expect vastly improved performance, thanks to an overall IPC improvement, cache increase, new / improved SSE instructions, and a 45nm process which yields lessened power requirements and consequent reduced thermal output.
I, however, take this noteworthy 4140 MHz (on air) achievement, with a grain of salt… as I usually do with other Intel benchmarks involving engineering samples.
The latest of these (ES models) caused a great stir, and to Intel’s credit, helped to stimulate the market (and their market share) via their robust marketing engine, which includes handing out the best-performing engineering samples for review (amongst countless other avenues).
I speak of the recent Q6600 and E6850 (G0 stepping), which echoed in forums near and far with 3.6 GHz and 4.0 GHz claims, respectively, on air and with little to no voltage increase (again, we speak of engineering samples).
While there are some exceptions, there are very few who have an absolutely stable Q6600 above 3.2 GHz or E6850 above 3.7 GHz on air (without having to increase voltage significantly or contend with upper-threshold temperatures).
While 3.8 GHz is a more reasonable and realistic air-cooled maximum for the QX9650 (concerning 99% of the populace, who will not be endowed with an engineering sample), it is still quite a remarkable feat of engineering and a reflection of Intel’s absolute strength (and current dominance) in the market.
I love that all oc records have ATI cards in them though <G>
anyone else notice that kingpin has a higher cpu score with a 5.25GHZ q6850?
kinda funny. lol
