Originally scheduled to launch sometime in Q3 2017, with August as the most obvious target, it appears that Intel has pushed the launch for its new HEDT (High-end Desktop) X299 platform date forward to the 25th and 27th week of this year, which puts it somewhere at the end of June, beginning of July, timeframe. 

As detailed earlier, Intel Skylake-X lineup will include six- and ten-core CPUs, have support for quad-channel DDR4-2667 memory and should be the core of Intel's HEDT X299 LGA2066 platform.

The Kaby Lake-X lineup will only include quad-core SKUs, have a TDP of 112W and lack the integrated GPU, but also come with dual-channel DDR4-2667 memory support and 16 PCIe 3.0 lanes, down from up to 44 PCIe 3.0 lanes with the Skylake-X SKUs.

If the rumor, coming from Benchlife.info, proves out to be true, we should hear and see more about Intel's new X299 HEDT platform at the Computex 2017 show, kicking off on May 30th in Taipei.
