I've seen recently few videos how actually chips are being produced, step by step (sans all the secret details) and learned it takes 3 months for one GPU or CPU chip to be actually "printed" from clean silicone wafer to finished core. And then all the "stencils" (UV masks) cost $300k+ each and there's one needed for each layer inside the chip, so 18+ per chip usually needed. Then each separate error caught (like with Blackwell) requires new masks and restarting production - which is another 4+ months easily of delay. All that cost a huge amount of money, then there's whole r&d too, much more expensive on much more complex chips. These things can't be cheap anymore, everything around them is hugely expensive and any error done by the vendor cost them many millions in losses that they will add to the final price most likely.
