Power Consumption

Since the raw performance benchmarks for the new Core i7 chips did not have anything out of the ordinary, we were hoping that the power consumption numbers would be different. The testing got off to a good start, with the desktop idle figures for the i7-975 and i7-950 doing better than their corresponding 'rivals'. As our i7-940 power testing was done on a different motherboard, it accounts for the larger gap in the figures between the i7-950 and 940. Hence, examining the i7-975 versus 965 numbers should be more representative between the two different CPU steppings (both processors idle at the same clock speed). In our opinion, it's a decent improvement and definitely for the better.

Once we started loading the CPUs however, the power numbers for the new Core i7 processors ended up mostly higher. With their higher default clock speeds, these figures are likely accurate, though interestingly, the processor seemed to have hit a peak of around 293 - 294W for the SPECviewperf 10 benchmark, as we found both the i7-975 and 965 having similar power consumption figures. Again this could the advantage of the new core stepping that's making its presence felt where possible.
