Selling at a loss in the US would be very bad for Nvidia. Trying to "subsidise" that by increasing prices in other regions would make things even worse. If Nvidia could get more revenue by increasing prices in those regions, it would have done so. Assuming Nvidia has got its sums and market research right, raising prices in those regions would actually lower overall revenue.It would be selling at a loss in the US but it would be subsidised by the rest of us. And it's probably AIBs that are more affected than this than Nvidia themselves, depending where the FE cards are assembled. Companies will have a choice between lowering demand significantly in the US by increasing prices there, or spreading out the demand loss a bit across multiple locations and subsidiaries. I think we will have to see what happens here.
It's not widely appreciated just how much tariffs would hurt the US. Even Trump's narrative for them is that they will cause short term pain, but that this will be offset once companies move manufacturing to the US (which isn't very likely on a large scale).
