> The PCIe lane story is stuff of fanboys. It comes at a cost, power and heat.
Could you unpack this a bit? Specifically, I'm curious if the cost is a premium per lane (e.g. W/lane greater on AMD than on Intel) [1]. Also, is that cost at all affected by the I/O volume or merely the CPU being power-hungry overall?
[1] Of course, that assumes everything else being equal, which it can't be, as well as equal proprotion of PCIe utilization, which is unlikely.
