Coffee Lake is Intel’s codename for the third 14 nm process refinement following Broadwell, Skylake, and Kaby Lake. The integrated graphics on Coffee Lake chips allow support for DP 1.2 to HDMI 2.0 and HDCP 2.2 connectivity. Coffee Lake natively supports DDR4-2666 MHz memory in dual channel mode.
Desktop Coffee Lake CPUs introduce a major change in Intel’s Core CPUs nomenclature, in that i5 and i7 CPUs feature six cores (along with hyper-threading in the case of the latter). i3 CPUs, having four cores and dropping hyper-threading for the first time, received a change as well.
