Below are the temperatures measured for each of our Broadwell-E CPUs at stock settings – without any overclock applied. We’ve also compared the 6900K and 6950X to their Skylake counterparts (which we’ve also benchmarked against on the subsequent pages too):
Overclocking
Intel Core i7-6900K
We managed to overclock the i7-6900K from its base clock of 3.2GHz to 4.4GHz by adjusting the ratio/multiplier to 44 – a 37% overclock. This is an admirable achievement and should present us with a significant boost in performance compared to the stock settings. To reach this point, our chip required a substantial voltage increase – 1.34v.
Intel Core i7-6950X
Turning to the Extreme - Core i7-6950X, which has a total of 10 cores, we were able to hit the same result of 4.4GHz for our maximum overclock. Since the Extreme CPU sits at a lower base clock, this represents an impressive 46% increase over stock settings. The lowest possible voltage required for this overclock was 1.31v. As you can see the temperatures were quite high, so increasing the voltage to accommodate a higher frequency wasn’t an option.
On the subsequent pages we’ll be benchmarking both CPUs at stock and overclocked settings, showing you what you can expect out of the box and what can be assumed with a substantial overclock applied.
