Overclockworkbench tests Phenom II vs i7 940 and QX9770
Hey people, overclockworkbench seems to just broke the NDA(if they ever signed one that is),and tested Phenom II 940 vs QX9770 vs Core i7 940:

Site is opening slow atm,but Phenom II results seem pretty good,considering the fact both intel QC chips ran at higher clock(QX9770 is 3.2Ghz CPU while Core i7 mostly turbos up to 3066Mhz)
edit: Cinebench 10 32bit scores seem to be way low for their Phenom II system,900-1000pts lower.In 32bit Phenom II @3Ghz should score ~10500 and not ~9600pts... I can't say what's going on there,but their results are hindered in some way in this test(only?).
Also the OCing page made me laugh since they seem to up the NB volts and leave it NB clock at default?? :p: Maybe they don't know that HyperTransport and NB are not the one and the same thing... Note the 3Dmark06 CPU score is 14% lower than the same clocked 3.8Ghz Phenom II we already saw in Shanghai review thread(5700pts @ 3.8Ghz).These numbers really are weird,be it their BIOS version or OS issues.

In our tests, the Phenom II X4 940 (3GHz) is overclockable to 4GHz by AIR with the use of the AMD overclocking tool or ASRock OC Tuner, the stable condition where most benchmarks will complete is 3.8GHz. In fact, a 800MHz overclock can be achieve using two ways. One, is by using a higher multiplier x 200 (e.g 200x19). Alternatively, we can run it at 15 x 253MHz. Do take note that if CPU CLK is raised to 250MHz, considerations must be made for the Hypertransport speed to fall in the range of 1.8GHz. The memory timings should also be more relaxed and select a ratio e.g DDR2-533 to ensure that memory is not the bottleneck to overclocking.
In the following page, we present some of the screen shots of running the CPU+board at 3.8GHz.
Settings used
{Advanced -> CPU Configuration}
Multiplier/Voltage Change => Manual
CPU Frequency Multiplier => x19.0 3800 MHz
CPU Voltage => 1.5250 V
NB Frequency Multiplier => x9.0 1800 MHz
NB Voltage => 1.3500 V
{Advanced -> Chipset Configuration}
Advanced Clock Calibration => Auto
mGPU => 1.40 V
edit 2: now look at the CPU Vantage score in OCed mode,the scaling is very bad.Wth is going on with their scores,how can they miss this(they can't be such n00bs,can they? :p: j/k). The CPU score @3.8Ghz is 11471pts while at default 3Ghz is ~10050pts ,that's a massively low score for OCed speed of 3.8GHz.The 11471pts is what a Phenom II @ 3.44Ghz would get ,not at 3.8Ghz.
