well, it's nice to see tech moving along, I can not figure out why power requirements keep going up. while pcie 3 bandwidth is still just being surpassed.
Maybe in the consumer space. In the enterprise space, once SSDs became economically viable. PCIe went from 3.0 being vastly sufficient to 4.0 being too little too late, hence the rush to 5.0 and accelerated time table to 6.0.

In the consumer space, we're mostly seeing the PCIe bandwidth crunch on lower-end GPUs that need to rely more heavily on system memory. In the not-so-distant-future, we may also see it with DirectStorage titles needing more PCIe bandwidth to cache more higher-definition assets in system memory.

Transistors dissipate power when they're switching states. The more times it switches, the more power it dissipates.
Thankfully, power goes down as operating and signalling voltages and parasitic capacitances go down. Give this stuff two or three product generations to mature on all fronts, then we'll probably get 6.0 performance squeezed in the same power budgets as 4.0 today. First-gen 4.0 products were power hogs too.
