I don’t think thinking of them as “stripped down CPU cores” is accurate. They are very different beasts these days, with GPUs executing multiple threads in lockstep, not having a stack etc.
As far as “math”. GPUs can do pretty much everything in the sense they are turing complete, but at the same time if you’re asking instruction-wise, GPUs won’t have all the extra super-specific stuff that the x64 instruction set has for example. You’d need to write more stuff yourself.
I’m not sure exactly at what level you’re asking the question.
