> Isn't it because we insist on only using the latest nodes from a single company for manufacture?

TSMC was way ahead of anyone else introducing 5nm. There's a long lead time porting a chip to a new process from a different manufacturer.

NVidia do this. You can get older GPUs, but more performance is better for performance sensitive applications like training or running LLMs.

Higher performance needs better manufacturing processes.
