Honest question coming from a point of consumer-thinking ignorance: With GPU makers putting out x8 cards on PCIe 4.0 and the heat issues with PCIe 5.0 SSDs, what practical nonenterprise uses are these speeds going to have?

    Ah … I didn’t realize “downscaling” (there’s a better term I’m sure) at the motherboard level to older generations was a thing. Wait. Is that already a thing with some of the 5.0/4.0 boards?

      Yes, that’s what they have been doing for quite a while now.

      The chipset splits a few PCIe lanes from the CPU into many PCIe lanes for lower speed devices to use. Of course those lanes all share the same bandwidth with each other and with the USB and SATA ports in the chipset.
