They fabbed a lot of AI chips. Nvidia's Ampere chips up to 3090 were made by Samsung in 8 nm. Interestingly the chips bigger than those found in the 3090 (so GA100s for A100s) were made by TSMC on a 7 nm node. Maybe Samsung's yield was not high enough to produce those large chips (AD100 is 826 mmsq and would probably be even bigger on Samsung's node).
