No you wouldn't need an AMD GPU to get full performance.
Bang for buck they are better than the Intel, and being a relatively new release, I expect we could still see some BIOS updates and driver updates giving a little extra performance. haven't done the calculations myself though, someone more knowledgeable could probably offer better insight.
