According to a report by DigiTimes, factories in Taiwan are already ramping up to help NVIDIA bring out its RTX 4000 series gaming GPUs in 2022, based on 5nm lithography. Notably, the report indicates that "Hopper," rather than being a new GPU generation, will be an MCM architecture for datacenter and HPC use cases.

Lol 7nm Ampere? It's 8nm Samsung node!
I hope they go back to TSMC process for Lovelace. Samsung nodes sucked hard...
Currently AMD has the advantage of TSMC's 7N (vs Nvidia using Samsung's 8N) (-> easy 30% higher power cunsumption). AMD is expected to use TSMC's 5N (although recently news regarding the switch to Samsung also appeared), but if Nvidia is also going to 5N, then AMD may need to work on their power efficiency, or go to TSMC's 4N, but Apple is already going to use up the 4N capacity (yes, AMD is not likely to use TSMC's 4N anyway). I don't like Nvidia, but I like that they introduced Raytracing and hope they go to TSMC's 5N - competition is good for customer.
