Overclocking

Overclocking Haswell processors is perhaps as much down to luck as much as skill. We increased the core voltage to 1.25V and managed to run at 4.5GHz on all cores. The IGP was overclocked separately, and we cranked it up from 1,200MHz to 1,600MHz by increasing voltage from 1V to 1.15V.

Single-threaded performance doesn't rely on hyperthreading; Core i5-4670K at 4.5GHz easily surpasses the 4770K's performance.

Though having access to eight threads enables the range-topping chip to keep its lead in Cinebench.

Increasing the IGP core, which is the same architecture as the HD 4770K's, pays solid dividends, but there's still not enough raw speed to beat a stock-clocked AMD A10-6800K.
