In theory, the answer is computable, but it probably doesn’t mean what you think it does. A gigantic chunk of those transistors are just SRAM memory cells for various caches. The number of transistors used to actually implement the logic of the SoC is significantly smaller. I would be surprised if it was more than 5%. The growth of this number between generations is also likely not very large. Most of the growth is also probably cache sizes.
