The only way to do that, like seriously do that, is to regress all of the GPU technology developed in the past two decades. Otherwise software and maybe even hardware lockouts won't prevent a determined hacker to get the thing to do what they want. Case in point, so-called "Mining only" GPUs can actually run games and people have gotten Quadro divers to run on GeForce GPUs by simply removing a tiny SMT component.The easiest solution is the one that was before, way back when GPUs were only used for games. Someone said 3dfx, yeah those times. If the GPU dedicated for gaming is only good for that, has only functions for games, no one else would buy it, but gamers.
Manufacturers almost never want downtime on their facilities. Being able to anticipate higher demand in the future means keeping some capacity on idle. And that idle capacity is lost money because you know, it could be used to build chips.I said nothing of ramping up production overnight. Which is exactly why they have teams analyzing and anticipating demand - so they can secure manufacturing capacity months in advance. That was the entire point of my comment - not that they could wave a magic wand and magically ramp up production to solve the problem now.
Building a new fab or upgrading an existing one still takes years before it can reach commercial manufacturing capability.
