Intel this week released its new Rapid Storage Technologies drivers, and thanks to their associated release notes, Intel has indirectly confirmed their upcoming Z390 and X399 PCHs. The drivers' release notes also shed some light on Intel’s 9th Generation Core processors as well as features of Intel’s future HEDT platform.

Intel’s new and upcoming platforms for desktops and workstations rely on the company’s Cannon Point-H (CNP-H) PCH silicon in various configurations and with various differentiators, according to release notes for the Intel RST version 16.0 driver. The CNP-H chip itself is already in high volume production and is sold to PC makers under the CM246, HM370, QM370, H370, H310, Q370, and B360 SKUs. Said chipsets power high-performance laptops based on mobile Coffee Lake processors as well as new motherboards for consumer and corporate desktops. Going forward, Intel’s Cannon Point-H PCH will also be used for various desktops (under the Z390, H310, H370, Q370, Q360, B360 model numbers), workstations (under the C246 model number), and high-end desktops (under the X399 SKU).

It is noteworthy that the Intel X399 PCH will be validated only with the Skylake-X CPUs (at least initially), leaving the unusual Kaby Lake-X family notably absent. It remains to be seen whether Intel plans to rebrand Skylake-X processors for the X399 platform in a bid to emphasize possible new features of the platform, but typically the company does not do anything like this in the HEDT segment.

Intel’s upcoming low-power laptop platforms running the 9th Generation Core "Cannon Lake-U" SoCs will use a different PCH known as the Cannon Point-LP. The document does not say anything about usage of non-Cannon Lake silicon in the 9th Gen Core family for low-power notebooks, so it looks like the said platforms will rely solely on Intel’s CPUs made using its 10 nm process technology. At the same time, it is also noteworthy that Intel does not list any Cannon Lake-Y SoCs in the release notes, so the destiny of such products remains unknown.

Since release notes for the drivers are not meant to announce precise product specifications, it is impossible to say what exactly to expect from the Z390 or the X399 PCHs. Meanwhile, general specs of the Q370, H370 SKUs and other PCHs based on the CNP-H silicon are well known, so the base functionality of the upcoming chipsets is more or less obvious

    Not exactly. It just states that it adds support for the rest of 300 series PCH.
    Z370 was already introduced in earlier version.

    Generally CPU data is quite a bit inconsistent. Look at the x399, supposedly CNL/CFL but with note "only SKL-X support" ... makes no sense.
    Or for 200 series where only KBL is mentioned, but I think SKL works as well.

    "is a little bit of courtesy like not using the same name for chipsets too much to ask for."
    -------------------------------------------------------------------------------------------------------------------

    or using the same engineers?

    or killing whatever remained of the personal computer?

    or.....

    Oh yeah, we know what happens if we say too much

    "Intel's 300-Series and 240-Series PCHs" table does not include Z370 for some reason, although "Intel's 300-series PCH" table just below does. Reply

    because its more of "introduced support for the rest of 300 series PCH"
    while z370 was introduced in earlier version.

    6w EVEN ON THE PATHETIC h310? Reply
