Kaby Lake builds upon the Skylake architecture, most dies are slight enhancements of their Skylake counterparts. The biggest change is the removal of the high performance quad core GT4 die, which has been replaced by the Kaby Lake G processors. And the introduction of the first low power quad core processor.
