Most of it is due to Apple using a more modern fabrication process with smaller structures (5nm). Some of it is due to optimizations like having efficiency cores that can handle non-demanding workloads with less energy consumption than the regular cores. I expect Intel & AMD chips to quickly catch up once they switch to more modern processes as well. Currently Intel still uses a 14 nm process for their Coffee Lake processors, so no matter how good their design might be they just can't compete with a chip that's built using a 5nm process, as the physical characteristics are completely different.

- ThePhysicist 6y agoIn a nutshell, smaller transistors draw less energy at a given operating frequency. According to TMSC the 5 nm transistors draw 30 % less power as compared to their 7 nm ones [1]. Of course the devil's in the details, but a large fraction of the performance and efficiency gains can be attributed to the process.
