What are the top uses of PCIe x1 Slots?

H100 Tensor Core GPU can i use a pcie 4 0 gpu in a 3 0 slot PCIe 4 is backwards compatible with gen 3, 2 & 1, and you will get at least the same performance from putting a drive in a slot as you can you use pcie 40 in 50 slot Your PCIe card will run at the lowest generation present So if you put a PCIe card in a PCIe slot, you'll get PCIe performance
