I'm not sure that's a fair comparison. The difference in the product lifecycle is too big. A GPU has a 3 year depreciation cycle and continues working for well over a decade after that, if I buy gas today I need new gas tomorrow. The market can react in the timespan of years, it can't react in the timespan of weeks, and having a product that isn't used up makes timelines more elastic.
If we eliminate both factors by imagining a world where GPUs just stop working every three years and where AMD doesn't have time to ramp up production we'd be pretty screwed without Nvidia, and everything depending on GPUs would quickly grind to a halt. AMD sells a tiny number of dedicated GPUs compared to Nvidia, and right now they have no spare capacity
