There are some other knobs that NVIDIA will surely try (has surely tried?) to tweak as well, such as making the consumer devices deliberately less power efficient, fusing off chip features which make compute workloads more efficient, or sabotaging the drivers (either in general or on a per-application basis). With disks there was always just as much pressure on the consumer side to keep energy down, cost down, and capacity up, which means that there was no natural segmentation, and no straightforward unnatural segmentation.
