The Intel Core i5-6600K processor is based on the new "Skylake" 14nm manufacturing technology. Beyond mere clock speed increases, the biggest changes from the previous generation are under the lid. The on-chip memory controller now supports DDR4 memory, although it still retains a DDR3 controller. The fully integrated voltage regulator (FIVR) introduced with Haswell is gone, meaning users now have complete control over voltages through the BIOS. Processor base frequency comprises 3.50 GHz while the Intel Core i5-6600, this processor's predecessor, had a base frequency of 3.30 GHz.
