According to a leaked and blurry internal Intel presentation, which originally showed up at Anandtech forum, Intel is preparing to launch four Skylake-X SKUs, with six-, eight-, ten- and twelve-cores, all of which will be the first Core i9 processors from the company, leaving the Core i7 to Kaby Lake-X quad-core and earlier Kaby Lake CPUs high-end and gaming CPUs.

The same source suggests that these Skylake-X LGA2066 socket CPUs could be launched in June and all feature HyperThreading as well as 1MB of dedicated L2 cache per core, which is four times more than the Core i7-7700K. As noted, the Skylake-X lineup will include four SKUs, the 12-core Core i9-7920X, 10-core Core i9-7900X, 8-core Core i9-7820X and the 6-core Core i9-7800X.

The specifications of the flagship 12-core Core i9-7920X are still unknown but it should pack 16.5MB of L3 cache and will definitely be the fastest Intel Core CPU on the market, judging by the known specifications. The 10-core Core i9-7900X has 13.75MB of L3 cache and works at 3.3GHz base and 4.3GHz Turbo clocks. The Core i9-7820X has 11MB of L3 cache shared among those eight cores and works at 3.6GHz base and 4.3GHz Turbo clock. The 6-core Core i9-7800X will have 8.25MB of L3 cache and work at 3.5GHz base and 4.0GHz Turbo clock.

The list also includes two Kaby Lake-X quad-core SKUs, including the Core i7-7740K and the Core i7-7640K. Both of these will also have 1MB of L2 cache but have 28 PCIe 3.0 lanes, just like the two lower placed Core i9 SKUs, the Core i9-7800X and the Core i9-7820X. Bear in mind that Kaby Lake-X CPUs will also have dual-channel DDR4 memory support while the Skylake-X will have full quad-channel DDR4 memory support.

The Core i7-7740K has HyperThreading support, comes with 8MB of L3 cache and works at 4.3GHz base and 4.5GHz Turbo clocks. The Core i7-7640K surprisingly lacks HyperThreading, has 6MB of L3 cache and works at 4.0GHz base and 4.2GHz Turbo clocks.

Unlike these Kaby Lake-X and 6-core and 8-core Skylake-X SKUs, the 10-core and 12-core Skylake-X Core i9 SKUs, the Core i9-7900X and the Core i9-7920X will have 44 PCIe 3.0 lanes, which means they will get support for 3-way/4-way SLI/Crossfire support.

While these are still just unconfirmed rumors, the presentation looks legit and it is pretty much what we have been hearing around since Intel is looking for a way to get ahead of AMD and its recent Ryzen push.
