Which chips are these? It seems the main challenge is data bus speed and memory capacity now and it seems no one can really compete with NVIDIA now? And i doubt NVIDIA is still optimizing for anything expect LLMs/AI, their last keynote had less than two minutes of gaming related content and they even canceled their new generation of gaming cards for now.

And it seems all of these advanced chips rely on the most advanced lithography which is tightly guarded and supply locked by a few companies.
