Well I was talking about heat. But regarding radiation, there is a long history of transistors in space dealing with radiation. But ... there is also a whole science how to deal with making it reliable: answer, expensive redundancy.
And about starlink .. as far as I know the fail quite often but work, because of redundancy. So they get replaced.
If you want to ship GPU's to the orbit, then this surely works somehow, if you are willing to replace them often, which is expensive. Or you shield them, but then you will need to get up heavy shields. In general, of course computers work in space, but it is not cheap.
I don't follow your logic. I mentioned starlink as an example of transistors (and solar panels) in space dealing with radiation.
