Clock-for-clock Performance

With both CPUs now clocked at 4GHz the Core i7-5775C and Core i7-4790K delivered virtually the same memory bandwidth.

Interestingly we see a slight performance advantage in favour of the Core i7-5775C when measuring L2 cache performance.

Clock-for-clock the Core i7-5775C scored higher in Cinebench, out doing the i7-4790K by a 4% margin.

The PCMark 7 score was virtually the same on both processors, certainly well within the margin of error.

Again we find the Core i7-5775C to be 4% faster than the i7-4790K once their clock speeds are matched.

The Core i7-5775C enjoyed a 6% performance advantage in the Hybrid x265 conversion test.
