Question Is PCIe version 5.0 compatible with an old motherboard with PCIe version 3.0?

[matthewbaynham]

I have a old tower with a ASRock X399 Taichi motherboard where I have 4 x PCI Express 3.0 x16 Slots link to full spec

I don't have a very powerful graphics card because I don't play games, but I want to start using Ollama and this uses the GPU NVidia graphics cards and some AMD graphics cards.

Anyway I need to buy a graphics card for my old tower. But when I look at websites selling graphics cards they are PCIe version 5.0 is this backward compatible?

I just need a cheap GPU that will work on my motherboard which is also compatible with Ollama, does anyone have any advice for me for what is compatible?

PCIe 5.0 devices will work on PCIe 3.0 slots just that you won't get PCIe5.0 speeds.
