Once two giant companies are dealing with each other it can get really complicated to cut everything off.
There is no such hypocrisy if they use Samsung refrigerators.
Training the model requires inference for forward propagation, so even then, for your comment to be relevant, you'd need to find a plot that Apple uses to compare inference on quantized models versus Nvidia, which doesn't exist.
That's kinda the point of my original comment. Apple claims to know what's best, but contradict themselves through their own actions. We wouldn't be in awkward situations like this if Apple didn't staunchly box-out competitors and force customers to follow them or abandon the ecosystem. It's almost vindicating for people like me, who left MacOS because of these pointless decisions.
So rather than invest engineering resources to re-imagine the fridge, they can simply buy them from established manufacturers that make household appliances like Samsung, Sony etc.
