Intel Skylake-X And Kaby Lake-X LGA 2066 Socket Processors Launching In 2H 2017
This isn't the first we've heard of Skylake-X and Kaby Lake-X, which are aimed at enthusiasts but no longer bearing the "E" extension. What's new and interesting about these high-end parts is even though they're based on different architectures, they may end up being supported by the same platform, a new one codenamed Basin Falls-X.
Basin Falls-X will feature Intel's forthcoming Socket R4 (LGA 2066). The higher pin count compared to LGA 2011 means that all current processors get left behind—you won't be plopping your 10-core Broadwell-E processor into a motherboard based on Basin Falls-X. Interestingly, Basin Falls-X will feature quad-channel memory support for Skylake-X and dual-channel memory support for Kaby Lake-X processors.
Skylake-X will come in same core configurations as Broadwell-E with 10-core, 8-core, and 6-core models in the works. The 10-core and 8-core models will have 44 PCIe Gen3 lanes, while the 6-core variant is cut down to 28 PCIe Gen3 lanes. All three will have a rated TDP of 140W, same as Broadwell-E., so you're getting a bump in performance without increasing the power draw.
Kaby Lake-X will have up to 16 PCIe Gen3 lanes to work with Basin Falls-X. The sole four-core part will also have 8MB of cache, Turbo Boost 2.0 technology (Skylake-X gets Turbo Boost 3.0), and a 112W TDP. Since they share the same platform, both processor families could debut around the same time in Q3 of next year.
