Skylake CPUs are Intel's latest generation of Core CPUs (6th Generation). Skylake CPUs feature 14nm architecture. Skylake CPUs have improved the onboard graphic performance of the motherboard (via the CPU). As of this writing the only CPUs that have come out as Skylake are Socket 1151 CPUs for use on the Z170 and H170 motherboards. Near the end of this year (2015) consumer oriented server CPUs and boards (Xeon E3) are supposed to be available with the latest architecture. In the meantime, Xeon E3 CPUs continue to come out in Socket 1150, 22nm architecture. Around Spring of 2016, professional level CPUs (Socket 2011 and Xeon E5) and boards are expected to be released with Skylake (14nm) architecture. Even though there are fewer Socket 1150 PCs available, some of our PCs are still Socket 1150. If your main concern isn't improved graphics responsiveness straight from the motherboard, you might be able to get a faster PC (for the time being) for the same amount of money by going with a Socket 1150 PC. If you are looking for a professional computer, on the cutting edge of technology, you should still be looking at Socket 2011 v3 such as those PCs in our Quiet Elite section and our Quiet Server section. Even though Intel has not released Skylake for their professional line of CPUs (currently Socket 2011 v3) and motherboards, still outperform the new Skylake Socket 1151 CPUs. You can read more about Intel's continuing advancements in microarchitecture HERE. Socket 1151 CPUs (used on such motherboard chipsets as Z170, H170, and B150) will be featuring several improvements. Most of Intel's improvements, for now, center around improving the graphics performance of their CPUs. Socket 1151 CPUs are also supposed to run cooler than their predecessors (Haswell and Broadwell Socket 1150 CPUs), and will eventually run faster than Socket 1150 CPUs. Lower end Socket 1151 also have yet to be released. So for now, Skylake CPUs are more expensive than their predecessors. At the same time, motherboards for Socket 1150 are starting to go out of production, making Skylake PCs the logical choice.
