AnandTech reports Intel's chipset driver documents reveal the latest version of the driver support the future 400-series chipset family as well as the 495 series chipset family. Both entries haven't been announced yet and we can only speculate about their features and capabilities.
Another interesting addition to Intel’s family of chipsets is the H310D PCH, found in the same document. Based on its name, we can suspect that this is a yet another version of the entry-level H310, but we have no idea about its peculiarities. The original H310 was built on 14nm, the H310C was built on 22nm, so who knows what the H310D will be.
A quick Google search reveals this isn't the first time Intel has named these parts. Apparently, reference to the 400 and 495 series were found in the chipset drivers back in May. The 400-series is for the Comet Lake processor series while the 495 chipset is for Ice Lake.
