Previously known as Skylake-E, Intel would rename their Skylake-E family to Skylake-X to represent their market positioning at the high-end desktop PCs. Intels Skylake-X family would be launching in Q2 2017. Along with the Skylake-X family, Intel would also launch Kaby Lake-X. The Kaby Lake-X chips are also aimed at the enthusiast PC market but these are actually the Kaby Lake-K (Unlocked) processors which will be hitting the LGA 1151 sockets. More details on these families are listed below:
The Intel Skylake-X family is a new name for Skylake-E which is built for high-end desktop PCs. The family will be aimed at enthusiasts and will be launching in Q2 2017. So we can expect a launch close to Computex 2017 that is highly possible. The Skylake-X processors will be replacing the Broadwell-E family which launched a few days ago. Information suggests that Skylake-X processors will be available in same core configuration as Broadwell-E with 10, 8 and 6 core variants and TDPs adjusted around 140W while delivering better IPC with the new Skylake architecture.
It looks like Skylake-X family wont be compatible with the new Socket P (LGA 3647) which we saw earlier. That socket is being built for 2S, 4S and 8S+ configurations so 1S processors will still feature support on Socket R that is LGA 2011-3. Intel will be however making a new PCH known as Kaby Lake PCH which will allow compatibility for the Skylake-X and Skylake-W chips.
The Intel Kaby Lake-X family will be part of the Kaby Lake desktop family of processors. While the Kaby Lake-S series will be aimed at the mainstream desktop audience, those who want unlocked chips will have to wait till Q2 2017 to get hands on Kaby Lake-X series. These processors will be unlocked, fast and deliver better designs to support overclocking. Since Kaby Lake is a architecture optimization on the same node as Intels new PAO ( Process / Architecture / Optimization) roadmap puts it, we will be looking at quad core designs with TDPs set around 95W.
The Skylake-W or Skylake workstation family configured for 1S platforms will also be launching in 2017. This family will feature support on the Basin Falls platform which was confirmed in a previous leak. These chips have a lot in common with Skylake-X as they share the same socket (Socket R LGA 2011-3) and the same chipset. The chipset will be known as Kaby Lake PCH which means it will allow extended support for Kaby Lake-E and also 10 nm Cannonlake-X and Cannonlake-W processors.
The Skylake-W Basin Falls platform will house high-end chips based on the Skylake architecture. These chips will feature 140W TDP and will be available in both LCC and HCC die variants so we can expect high core count reaching up to 28 on these processors. The processors will be able to support quad channel DDR4 memory with rated speeds of 2667 MHz and will deliver up to 48 PCI-E Gen 3 lanes. Some of the features of the Kaby Lake PCH are that it delivers 10 USB 3.0 ports, up to 8 SATA Gen 3 ports and up to 20 PCI-E Gen 3 lanes. This delivers up to 68 PCI-e Gen 3 lanes on Basin Falls platform. Theres also of course future compatibility with Cannonlake-W chips.
