There is a noticeable performance jump from the Core i7-4770K to the new 6700K.
When comparing minimum framerates, the 6700K was 17% faster.
Looking to AMD’s processors, we find the FX-series producing some rather impressive average frame rates.

Finally let’s look at how the fan favorite dual-core Pentium G3258 Anniversary Edition processor scales.
Oddly the minimum frame rate almost maxes out at just 3.5GHz where it dipped to 44fps.
The dual-core processor seems to be creating some kind of choke point that boosting the frequency can’t overcome.
Still with a minimum of 47fps and an average of 77fps the Pentium G3258 still enables playable performance.
