Intel’s Skylake-X and Kaby Lake-X Processors Detailed

The latest details regarding the launch of Intel’s next generation Skylake-X and Kaby Lake-X processors have been leaked by BenchLife. This leak includes slides that clear up the confusions surrounding the launch of the new processors. While Skylake-X and Kaby Lake-X family of processors are based on different architectures they will be featured on the same platform simultaneously.

It looks like both the families will be powered by the Kaby Lake Platform Control Hub (PCH). This platform will be knows as Basin Falls-X, this platform will support both Skylake-X and Skylake-X processors. Basin Falls-X will support the fastest Core i7 processors that will launch next year. Basin Falls-X will have the new Socket R4 (LGA 2066) which has 2066 pins which means current CPUs will not be compatible.


The Skylake-X family will have 6, 8, and 10 core SKUs with TDP’s rated at 140W. These chips will have 44 PCI-Express Gen. 3.0 lanes. Kaby Lake-X will only have 4-core chips and we are likely only looking at Core i5 and Core i7 models. Kaby Lake-X series of processors will feature up to 16 PCI-Express Gen 3.0 lanes. The Basin-X platform will include quad channel memory support on Skylake-X and dual channel memory support on Kaby Lake-X processors, with speeds up to 2667 MHz. The platform also has 10 USB 3.0, 8 USB 2.0, and the Intel LAN (Jacksonville PHY) chipset.


It is suggested that Basin Falls-X will last the market up until 2020. Intel will not only offer Skylake-X on this platform, but also Kaby Lake-X (10-core+) and Cannonlake-X processors down the line. It will be replaced by a new socket LGA 2076 platform in 2020.
