On a test bench from Nordic Hardware using an Intel i7-3770K, the ASUS Maximus V Gene and memory hitting around 2600MHz 7-11-7-28-1T we get to see some benchmarks in Super Pi and PiFast. The benchmark run was likely using liquid nitrogen to overclock in sub-zero conditions and the Intel Core i7-3770K managed to eat through Super Pi 1M at a clock speed of 6961.6MHz using a base clock of 110.5 and a multiplier of 63x scoring a time of 5.187s. For 32M as we see the clock speed backed down to 6650.1MHz, scoring 5m 2.843s.
In PiFast we see the clock speed at 6805.1MHz scoring 10.56s. Using these results along with information from the HWBOT database, we see a comparison to previous SuperPi 1M leaders including the record for Sandy Bridge and the World Record set by an Intel i7-980X, which the i7-3770K beat by almost 0.6s.
