Intel X79 Core i7 4960X Review
The extra performance per MHz shows up again in wPrime95. The i7-4960X is 3 tenths of a second faster in the 32M place test at stock, and 2 tenths of a second quicker when overclocked, despite the clock speed being less than its predecessor. In such a demanding test that always produces close results to gain tenths is a mightily impressive achievement.
x264 Benchmark v5
Onto encoding video with the x264 codec and the two chips are nearly inseparable, whether at stock or overclocked. Again the lesser overclock of the new CPU provides equal performance to the i7-3960X that came before.
