@dankcushions said in Any Difference in performance using 0/1 img on Pi 3B+:
another issue is compiler flags. the 0/1 have a different generation of ARM cpu, without some of the features of the 2/3, so they have binaries compiled without these features that would presumably run less efficiently on a 2/3 than with the right flags.
That is perhaps the strongest argument to use the correct image for your device. For example, the Raspberry Pi 0/1 does not support NEON instructions, which are used by many emulators for speed. The Raspberry Pi 2/3 does have NEON and also have a different processor with faster instructions. All of that can only be taken advantage of if the binaries are compiled for them. Running a RPI0/1 image on an RPI2/3 basically does not take advantage of any of these optimisations and will just underuse the better aspects of these devices.
