Every single M.2 slot listed in that diagram (all 3)are listed at 32Gbps, which is 4x PCI-E 3.0. Obviously the switches at the PCH to the 4x PCI-E slot which shows it listed at 4.0 specification is a bit misleading, since you can't have more than 4x 4.0 lanes from the PCH as that is all that is wired to it.
M.2 drives (well, one) do perform well on an Intel chipset. There's only 4 PCIe communication lanes there and bandwidth is shared with everything else on the chipset, so it might not be much of a limitation.
I'd like to know why the m.2 slot from the CPU doesn't support gen 4 speeds as well.
