True. And yet, if you buy an RTX 5090 today, costing $2400 and released in January this year, it's PCIe 5.0 x16

Does the second half not already talk to this? Adding on to it further, GN found a few % performance difference on a 5090 going from PCIe 3.0 to 5.0 https://gamersnexus.net/gpus/nvidia-rtx-5090-pcie-50-vs-40-v... meanwhile many DC use cases find PCIe 5.0 unusably slow, driving alternative (non-PCIe) interconnects.
