You are missing one important thing here.
You do not radiate all the heat away from a GPU, a modern GPU can run pretty hot. Also look up how this is getting better for the next generation of GPUs.
Maybe repeat your calculation with updated assumptions?
But even if you were completely right, your argument is that we can't do this tomorrow, yes I agree. Typical technology development cycles are about 5-10 years.
> You do not radiate all the heat away from a GPU, a modern GPU can run pretty hot.
Fascinating. Tell me more.
Where does the heat energy that isn't radiated away go?

LOL. If you don't radiate the heat the spacecraft just gets indefinitely hotter (until it glows and the heat is forcibly irradiated). It's space, there's no fluid to provide convection.
