Thanks for your informed opinion. > we still have at least 200x before we hit atomic feature size How so? The size of the silicon atom is 0.2nm, so we're already close to dealing with atomic scales. It seems likely we'll switch to an element like gallium, as a nearby comment mentioned, before we reach even 1nm node size. At that point the CNT manufacturing process would have matured beyond the current experimental, but promising, stage.[1] We can only speculate, but I reckon these changes will happen much earlier than 2050. > So yes, you could get a GPU that perform close to a GTX4090 by 2033 and it cost you less than $200. I sure hope we get to that point much sooner than that. :) NVIDIA and AMD are squeezing this performance at the expense of power, heat and size. Apple has proven it's possible to do this much more efficiently, but their silicon is still incredibly large compared to older generations. If we can get a better wafer yield with another material or process, while also reducing power and heat, then the only drawback for consumers could be cost, which should continue to go down. Though if NVIDIA has any say in the matter, they'll surely continue to price gouge consumers, as they've done this generation.
