Can someone tell me how much more power efficient is ARM actually? Like under load when gaming, not in a phone that sleeps most of the time. I've heard both claims, that it's still a huge difference and that for new AMD Zen it's basically the same.

It's workload-dependent. On-paper, ARM is more power-efficient at idle and simple ops, but slows down dramatically when trying to translate/compose SIMD instructions.

You seem to have conflated SIMD and emulation in the context of performance. ARM has it's own SIMD instructions and doesn't take a performance hit when executing those. Translating x86 SIMD to ARM has an overhead that causes a performance hit, which is due to emulation.
