Is the dominance of x86 due to any inherent properties of x86, or historical legacy? I think the xbox-s/x and ps5's choice of CPU vendor was driven more by business factors and the integrated graphics, than the virtues of x86 per se. The Switch does pretty well despite the less powerful CPU in the tegra.
