Before we move on to the benchmark results we would first like to quickly thank OCZ for supplying their Intel Haswell Ready Mk III Silencer power supplies. Haswell introduces the new C6 and C7 power states offering tremendously reduced idle power consumption with a minimum of 0.05A on 12V2, down from 0.5A on previous generation Ivy Bridge and Sandy Bridge CPUs.
Armed with DDR3-1866 memory the Intel Core i7-4770K produced a memory bandwidth of 21.33GB/s when testing with SiSoftware Sandra 2013. This is roughly the same bandwidth turned in by the i7-3770K and Ivy Bridge Core i5 processors.
Although the bandwidth between the CPU and RAM was similar to that of the Core i7-3770K, the i7-4770K is considerably faster when measuring L1 and L2 cache bandwidth. The L2 cache result in particular was impressive, reaching 1024GB/s which is 45% more than the i7-3960X and 100% more than the i7-3770K.
