Both of the new CPUs will support quad-channel DDR4, and while the Kaby Lake-X processors will take care of the mid/high-end markets, the Skylake-X is going to be a new beast. Intel's Skylake-X processor will be a huge 10-core/20-thread processor with undefined clock speeds for now, and 13.75MB of L3 cache.

Not only that, but Skylake-X is expected to support 48 PCIe 3.0 lanes for multi-GPU/enthusiast systems with add-on cards for RAID, 10GbE, etc. The Kaby Lake-X PCH itself has 24 PCIe 3.0 lanes, 10 x USB 3.0, and 8 x USB 2.0 - but the price of the Skylake-X is expected to reach around $1500, or more.

Both the new Kaby Lake-X and Skylake-X processors will be made on Intel's fresh 14nm process, with the Kaby Lake-X chips hitting a TDP of 112W, while Skylake-X ramps up to 140W. We'll be keeping a close eye on any news surrounding the next-gen processors, so stay tuned to TweakTown.
