NVIDIA’s products can colloquially be described as commodities in some contexts, as GPUs from NVIDIA can be interchangeable with GPUs from other manufacturers like AMD. For specific tasks like gaming or basic computing, the brand may not matter as much as the specifications, making them somewhat commodity-like in those scenarios
Whilst this isn’t the traditional economic definition of commodity, speaking loosely, I think it’s fair enough to describe GPUs as a form of commodity. The important thing is what’s being communicated, not the semantic definition. The above comment’s point was pretty clear IMO
