It's also just a weird nonsense comparison. You buy a GPU from Nvidia and you just get a GPU. You buy a Mac from Apple and you get a whole computer that includes a GPU.
To make a meaningful cost comparison we need to include an equivalent computer in which to put Nvidia's GPU.
Then we get into what workloads you need the GPU for.
