I think in this thread, Intel is mentioned as getting into the graphics card game. We can hope so.
Releasing more gpu models, whether by Nvidia, Amd or Intel, isn't going to resolve the availability problem. There's a general shortage of the silicon semiconductors (and to a somewhat lesser extent of manufacturing capacity) needed to make the chips that go into gpus (and basically all electronics that require them, including modern cars). It's why you see so many tech sites and channels vent their frustration at both Nvidia and Amd putting out yet more SKUs that use the same chipsets their existing gpus use, because their manufacturing partners (Asus, MSI, EVGA, etc) can't produce enough of those cards to meet demand to begin with, and it's basically asking/forcing them to spread themselves even thinner.
In fact, if Intel decides to enter the gpu market, things might actually become bit worse if that silicon shortage drags on and if Intel has no production of its own, because that'll be yet another player vying for the same already limited manufacturing time and resources everyone else wants. Tho even if Intel does have their own production for its gpus, there's still the matter of that silicon shortage, so they'll have divy up what resources they have between the gpu line and every other product line they have, and somehow produce enough stock for all of them. Unless they're secretly sitting on a mountain of silicon, an imo unlikely scenario.
Of course, none of that will matter if Intel's gpus turn out a poor value proposition. Or if the bots snag up all the stock. Or both.
