>>20930769GPUs haven't been state of the art for trainimg neural networks since 2015.
>>20930784CPUs aren't as good for high throughout floating point arithmetic that you need to render graphics. CPUs can do logical branching, i.e. decide whether or not to conditionally execute a block of code, but they generally have to do math one number at a time. GPUs can't do logical branching but they can do math on a whole bunch of numbers all at once.
