Not even close to true. Apple's ARM processors are unlike anyone else's, and everyone else's ARM processors are not particularly impressive. The power/performance isn't really there, and scaling performance up is not linear, either. You can't just "make it bigger" and retain the same power/performance ratio you had. The 1W power draw that the 'big' ARM cores target, like the Cortex-A78, isn't even that special. You can run x86 cores at 1W/core all day long as well. How it performs at the power level is the question, but the ARM cores don't really perform all that well. See for example the slaughtering that is the 64-core Graviton2 vs. the 64-core Epyc Rome: https://www.phoronix.com/scan.php?page=article&item=epyc-vs-... (spoiler, the x86 chip has an overall performance lead of 50%, and they really aren't targeting that different of a power budget) But even the M1 isn't an order of magnitude ahead on power/performance ratio. It's the leader, but it's sure as shit not 10x faster for the same power draw. |

Android phones with Qualcom Snapdragon 865 scores better than an Intel i7 7700HQ (4 cores, 8 threads) on Geekbench on multi-core and ties on single core while using a magnitude less energy.
While this i7 model is not new, it's not the "U" low voltage processor version.
I could see Qualcom getting fancy and trying to scale their processors at 5nm.
