Intel is allegedly preparing six HEDT processors, two based on Kabylake-X architecture and four based on Skylake-X. 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 (Kaby Lake-X) and 160W (Skylake-X).

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.
