    It's more so you can have a wider range of stuff rather than more bandwidth second to second.

    PCI-E 4.0 is not ready so you can't get more bandwidth per pin and it's the same socket and pin compatible so you don't have more pins.

    Is it a hardware limitation then? If so then it makes more sense.

    Maintaining the same socket, yes. Then again this is the main differentiation between high end and main stream platforms.

    It's still 2x8 for the GPU...

    Maybe PCI/e 4.0 will help us in the end. Or maybe Skylake-E notebooks will be a thing and we can have glorious 44 lanes on the CPU :D

    What I cannot find is, do the "Kaby Lake" chipsets have a cap on PCIe NVMe SSD Read/Write speeds.

    Don't think read writes would be limited. Unless the lanes get super saturated in the worst case insane load scenarios.

    It says Optane ready everywhere, but there is no hardware, so yeah...that's only for the 'paper tiger' for now...even 960 Pros are only just hitting the market these days...

    Still limited by the DMI 3.0 chipset-CPU link (PCI-E 3.0 4x Speeds)

    This is what I was asking about with the DMI. As far as I know, the cap on max data transferred through it (not including bursts) is about PCI/e 3.0 x4's worth, or around 4GB/s. This is why RAID-ing never passes that amount of data under any length of duration, and is known to have diminishing returns.

    I thought Z270 was supposed to increase this amount, but Meaker said it's a physical barrier to pass, and thus it won't be surpassing it until at least the next CPU socket.
