UPDATE: Intel has officially announced the Core-X series processors. More details on them here!

The most updated platform details on the Intel X299 platform that supports Skylake X and Kaby Lake X CPUs have just leaked out. Along with the HEDT platform, details concerning Intel's Coffee Lake S (mainstream) family of processors have also been revealed from Intel's Partner conference.

Intel X299 Skylake X and Kaby Lake X "Core X Series" Platform Details Unveiled Ahead of Launch

There are a ton of details shared on the new Intel CPU families, most of which we already know but some are new. During the conference, Intel mentioned that the new HEDT lineup would be called " Core X Series" so it's not known whether they will use the Core i7, Core i9 or Core X branding on the new processors. There will be a total of four Skylake X processors and two Kaby Lake X processors.

The Intel Skylake X HEDT family would feature a 6, 8, 10 and 12 core model. The 12 core model will be the flagship product of the family but unlike the other three, it would launch later in August and theremaining models would be available earlier in June. Intel's Kaby Lake X family would launch in June too, alongside the Skylake X parts and will feature two processors, both of which are based on quad core dies (More on these below).

Intel's Skylake-X platform promises to introduce the first ever 12-core SKU for the Mainstream/HEDT segment.

So before we get on to detail the specific models of the X299 HEDT family, let's take a look at what the chipset itself has to offer as there are a couple of major changes.

Intel’s new X299 chipset will be the latest PCH to support the enthusiast processors. The X299 platform will be centered around the LGA 2066 socketwhich will be compatible with at least two generations of processors. In specs, the X299 chipset offers up to 24 PCIe Gen 3.0 lanes. The chip also offers up to quad channel memory with speeds up to DDR4-2667 MHz (native). Kaby Lake X series processors will only support dual channel RAM but will stick to the native speeds of 2667 MHz.

The main difference is that while X99 allowed for 2 DIMMs per channel, X299 supports only single DIMM per channel with DDR4-2667 as opposed to DDR4-2400 which can still allow 2 DIMMS per channel. So while you were able to use all eight DIMM slots on the X99 boards, the same cannot be done with X299 when using DDR4-2667 memory.

Aside from that, Intel X299 has full support for CPU overclocking which is a bonus, we just hope that the CPUs are running cooler compared to the Kaby Lake S parts where Intel had to ask users to refrain from overclocking to avoid overheating issues.

The Basin Falls PCH also offers maximum of 14 USB ports(10 USB 3.0 Max), 8 SATA 3.0, and Intel LAN (Jacksonville PHY) controllers. The chipset can also drive three M.2 drives with Intel RST tech. Additional features include Enhanced SPI, SPI, LPC, SMBus and HD audio which are integrated underneath its hood.
