I think PCIe bandwidth has suddenly become super relevant. It used to be that videogames were not bottlenecked by PCIe bandwidth, and GPUs were the most data intensive thing on the bus.
Nowadays there's all sorts of business cases that require high bandwidth, and the devices to fill them also exist. From NVMe arrays to crazy interconnects to hyper connected machine learning accelerators, PCIe is enabling it all.
Now if only PCIe had woken up two years earlier and spent a bit more time on development… then PCIe 4 would be the equivalent to this new PCIe 6 standard.
