As expected the memory bandwidth performance of the Core i7-5775C is comparable to the higher clocked Core i7-4790K at 29.5GB/s.

The L2 and L3 cache performance of the Core i7-5775C is considerably slower than the i7-4790K for the simple fact that it is clocked a lot lower. Here we see a 17% reduction in L2 bandwidth and a 23% reduction in L3 bandwidth. Keep in mind the maximum operating frequency of the i7-5775C is 16% lower than the i7-4790K.
