Raspberry Pi OS 32-bit vs. 64-bit Performance

Some Raspberry Pi OS Linux distributions had already been providing 64-bit builds, but only now with the commonly used Raspberry Pi OS (Raspbian) are they having a proper 64-bit image available.

If using your newer Raspberry Pi single board computer for any computationally demanding work, it should pay off moving to the 64-bit AArch64 version of Raspberry Pi OS.

Across the few dozen different workloads tested, switching Raspberry Pi OS 11 for the 64-bit version improved the performance on average by about 48%. See all the 32-bit vs. 64-bit Raspberry Pi benchmarks over on OpenBenchmarking.org.
