"That's commonly repeated, but is a misunderstanding. Up until this point the difference was mostly that an x86 decoder took up more chip area, which given Intel's historical leads in process tech was no big deal to them. However now we're pushing chips to go wider than ever. Intel and AMD haven't been able to push past a 4x superscalar decoder. The instruction set just has too many potential chained dependencies to make it work. You'd have to slow cycle time or introduce additional pipeline stages such that performance in the net is worse. Meanwhile M1 decodes at 8x." Thank you, for the love of Christ why people regurgitate this [half-truth about the decoders] consciously without realizing what they are implying is beyond me. Sure, in a world where Apple, ARM. et. al were slow, maybe it would be a relevant defense. But they're playing ball, and MS/Intel haven't been up to bat with it the home turf truly on the line for years. Likely Intel will shift over to fabs for third-parties, MS is fine without Windows were it to fade out to Chrome/MacOS in time (unlikey but still). I think there's another variable on MS's end too. Paging. The M1 supports 16K paging/allocation unit sizes, right? I strongly suspect this + the ssd speed & memory compression plays a substantial role in the reported "differential use of ram" which probably also explains the swap rates that everyone keeps coping about (obviously, they are built this way for the most part). On performance though, I don't really put much stock in EclecticLightCo's thing on QoS, at least, not any stock in it as though I genuinely subscribe to the school of thought praising Apple for perfecting heterogeneous core scheduling, which is really just a bit much. And yeah, I went from 2020 x86 MBP to 2020 M1 MBA. Seamless, and I really haven't thought about emulation other than for instance the apparent memory usage that may be a bit more accentuated with Rosetta.
