I agree. There isn't much, although I would venture that on the flip side the costs of designing and validating an x86 microarchitecture are higher than an ARM64 microarchitecture.A78 has an either 64 or 32 KiB 4 way which isn't going to help in most workloads compared to Zen 2's 32 KiB 8 way associative cache. It's germane to the subject of some supposed instruction set superiority. There is almost none.
My comments above were re: N1; I don't have A78 hardware to play with so I can't speak to that. But I find it generally plausible that at least X1 exceeds Zen2 and SKL at iso clock.
