In the official documentation of Intel's release of the rapid storage technology 16.0.2.1.1086, Confirmed Z390 chipset and X399 chipset.
Z390 will support the Cannon Lake (CNL) and Coffee Lake (CFL) platforms. X399 is for HEL high performance enthusiast products of CNL/CFL. It is expected to be named as i7-8800X. (Schematic).
At the same time, Intel specifically stated in the remarks. The X399 is only compatible with the Skylake-X family of products. This shows that the LGA2066 interface has not changed, but Kaby Lake-X has been abandoned..
Of course, you carefully noticed , AMD also has the X399 motherboard, Intel this time seems to be hard, not as passive as its own B360 motherboard renamed, but consumers choose to get depressed ......
Simply put, the reason why Intel launched the Z390 is said to be preparing for the 8 core new flagship of the Coffee Lake family. Note that this 8 core is said to be the LGA1151 interface, that is, Intel brings 8 core 16 threads for the mainstream desktop CPU for the first time (after all, HEDT has had ...).
In addition, H370/B360 has added support for 802.11ac Wave2 and native USB 3.1 Gen 2 that Z370 does not have The latter is a bit embarrassing as a top chipset.
