Well, you mentioned the future, so I'm talking about the outlook. If a domestic 5 or 3 nm is developed and advanced chiplet packaging are available, there is no need for standalone GPUs in the future at least in the consumer space.
The consumer GPU market is tiny, most of the revenue that AMD/nVidia are generating from GPU are from corporate sales (
)
There is a market for gaming GPUs, the same way there is a market for Lamborghini and Ferraris, but it's not one that will drive investment.
Given that Huawei is a player in the Server and CPU space in China already, I imagine they would try to create a captive solution rather than any expansion cards. Especially as a "US IP Free" alternative. Now, rethinking what you said, I suppose you meant just discrete chips in general rather than specifically for graphics cards, which is certainly possible.
