Can anyone decode the following regarding the dual M2 setup on an Asrock H570M-ITX/ac:

- 1 x Hyper M.2 Socket (M2_1), supports M Key type 2280 M.2 PCI Express module up to Gen4x4 (64 Gb/s) (Only supported with 11th Gen Intel® Core™ Processors)*
- 1 x Ultra M.2 Socket (M2_2), supports M Key type 2280 M.2 SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen3 x4 (32 Gb/s)*

*Supports Intel® Optane™ Technology
Supports NVMe SSD as boot disks
Supports ASRock U.2 Kit

If I purchase an Intel i9-10850k will both M2 Slots work (of course at PCIE Gen 3 x4 speeds)??

Also, would having a Z590 motherboard be better in respect that it has 24 PCIE lanes as opposed to the 20 PCIE lanes on the H570M motherboard?

The reason I ask, is that I have two WD Black SN750 NVME PCIE storage devices, one is 500gb and the other is 1TB, and eventually (sometime in the long future it seems), I will purchase a RTX3080. As the Asrock website and manual doesn't give much in the way of diagrams, I'm just trying to work out if the 24 PCIE lanes will be better for running 2 x NVME PCIE devices along with the RTX3080 or the 20 PCIE lanes will be enough.

Im not into overclocking, but seeing as there doesn't seem to be a i9-10850 cpu, im happy to take the K version anyway, hence why I am looking at the H570 over the Z590.
 
you need a 11th rocket lake CPU to use that Hyper M.2 slot. it looks like they wired that to the CPU socket and unless you have 11th Gen CPU those PCIe lanes wont show up.
 
Thanks guys. So I would be better off waiting for the 11th Gen CPU's to appear rather than going for the i9-10850k as I previously had in mind.

So the other question is, the H or Z chipset, bearing in mind the H chipset has 20 PCIE lanes, and the Z chipset has 24 Pcie lanes. Would this make any difference when running an RTX3080 and the two M2 NVME Pcie Devices?
