> AMD switched some production to TSMC because they had much better defect rates at 7nm.

GloFo outright canceled their 7nm and smaller processes, back in 2018. All of AMD's leading-edge processors are now using TSMC 7nm, though the server and most desktop processors also incorporate a 12nm IO die. The days of AMD using GloFo are numbered.

Really, though, at this point it's easier to list what leading-edge chips aren't using TSMC: Intel's CPUs and FPGAs. All the other latest-and-greatest CPUs, GPUs, FPGAs and smartphone SoCs are made at TSMC. There's more diversity for memory manufacturing, and logic that doesn't need to be on a leading-edge process (eg. low-end smartphone SoCs, motherboard chipsets, SSD controllers).
