Please note that this post is tagged as a rumor.

It appears that Intel’s i9 series are actually happening. The Skylake-X and KabyLake-X series are to launch next month.

Intel i9 series feature up to 12 Cores

Intel is allegedly preparing six HEDT processors, two based on KabylakeX architecture and four based on SkylakeX. The most powerful CPU called i9-7920X will launch in August, while the rest will be available in June. The processors will have TDP up to 112W (KabylakeX) and 160W (SkylakeX).

The i9-7900 series will support up to 44 PCIe lanes, while i9-7800 are feature up to 28 lanes and i7-7700/7600 up to 16.

Three parts from i9 series will feature a third clock state called Turbo Clock 3.0, which essentially allows Intel’s Core-X CPUs to reach much higher clocks than Broadwell-E.

Allegedly Core-X processors have AVX512 extensions enabled. According to the leaker, the L2 cache size is 1MB. Skylake-X parts support quad-DDR4 2666 MHz, while Kabylake-X support dual-channel.

All processors expect i9-7920X are to launch next month, probably after PC Gaming Show, which Intel is sponsoring this year.
