It was expected that we would see a May / June release for Skylake-X and Kaby Lake-X that would coincide with Computex, but now looks like Intel will be pushing back the launch of these processors to the August / September 2017 timeframe.
For those who do not know Intel is releasing both Skylake-X and Kaby Lake-X at the same time because Skylake-X will offer 10-core, 8-core, and 6-core parts, whereas Kaby Lake-X will remain a quad-core part. The Skylake-X parts will have a 140W TDP and the Kaby Lake-X parts will be 112W. It is weird that Intel would be releasing a quad-core Kaby Lake-X part since the Core i7-7700K is already out.
Looking at the August / September time-frame Intel could do the launch at Gamescom in Germany. These processors will need a new socket, the 2066-socket, so that means you’ll need to buy a new motherboard. These new motherboards will feature the X299 chipset.
