Intel Confirms Z390 And X399 Chipsets For Coffee Lake And Cannon Lake
A document on Intel’s website [PDF] was recently discovered that draws attention to the company’s Rapid Storage Technology. However, found within the document are references to two unannounced chipsets: the Z390 and the X399. The Z390 will support both existing Coffee Lake processor and the incoming 10nm Cannon Lake family of processors. It will serve as the flagship for Intel’s mainstream desktop Coffee Lake processors. The Z390 supports current-generation “Coffee Lake” and upcoming “Cannon Lake” processors, while the X399 supports HEDT derivatives based on the two architectures, namely “Coffee Lake-X” and “Cannon Lake-X,” with no mention of “Skylake-X.”
The table (See Pic Below) mentions the chipset as supporting SKL-X (Skylake-X) and KBL-X (Kaby Lake-X), but it’s not clear if Intel is only referring to the forgettable i7-7740X and i5-7640X with “KBL-X.” The Z390 is rumored as being Intel’s next top mainstream-desktop chipset, with a long overdue update to onboard audio standards, in being a departure from the “Azalia” HD audio specification, onward to the new Programmable Quad-Core Audio with new SoundWire digital audio interface. The chipset is also rumored to feature 10 Gbps USB 3.1 ports.
Intel’s X399 is listed as supporting Coffee Lake and Cannon Lake. Currently, X299 is the home of Skylake-X and Kaby Lake-X parts; there are no Coffee Lake-branded parts for that platform. The previously known successor to Skylake-X was Cascade Lake-X. Because the name Cascade Lake comes from the Xeon product line, it’s possible that Intel has chosen to rename those parts as Coffee Lake-X.
The X299 chipset and its socket, LGA 2066, is only a year old, so we don’t expect X399 to use a different socket.
