Minor nitpick but the 4600G and 5600G mentioned in the article are Vega, not RDNA. The iGPUs in those two processors are/were quite powerful by iGPU standards at the time, especially considering they were competing with Intel HD graphics or very early Iris Xe iGPUs. Not a scratch on a good dedicated GPU though. Steam Deck is RDNA2 though, and is significantly faster. I don't think RDNA1 ever made it into an APU.
