The Ryzen IO dies are still made by GloFo
And probably some Polaris cards, some Ryzen 2000 chips, older EPYC chips, APUs, embedded Ryzen CPUs and who knows what else. But AMD probably already signed a deal with GF for the next one or two years that Intel probably can not cancel without paying a good amount of money. And even if they want to cancel that deal, until they get GF and takeover those factories, I guess some time will pass.
The thing is that AMD does not need GF's 12nm for much longer. With TSMC and Samsung going to 3nm, 7nm process probably will become much cheaper in the future, making it a viable alternative to GF's 12nm, even from a financial perspective. AMD is building Vega, RDNA, RDNA 2, Zen 2, Zen 3 and I/O(for mobile Ryzen chips) already at 7nm at TSMC. So, they don't really need to start redesigning stuff to 7nm. What AMD could have done all this time, but they didn't was to build APUs and low core count CPUs at 12nm GF. I mean, why not build 3400G and 3100, 3300 at 12nm and free 7nm capacity? Why not build mid/low end RDNA cards at 12nm GF to fill the mid/low end market? They probably had their reasons, but it proves that they don't really have much use of GF's 12nm.
