If you cut down a GPU enough, the CPU doesn’t become good, the GPU becomes bad.
Double precision fp (yes a different metric but the main one super computers are concerned about) performance of Nvidia 4080 is 761.52GFlops. Ryzen 9 7950x is about 256GFlops, so on that one metric, it’s not like the GPUs are orders of magnitude behind. At a certain point, using a cut down gaming card won’t make sense.
