It’s doing signal processing using floats, that can lead to differences in the result even if the implemented algorithm is identical. Float addition is not commutative so reordering some calculations, either in different implementations or with different compiler options, can lead to slightly different results. This just detects browser version and maybe OS/Architecture, the same browser binary should still give the same results between different devices with same hardware.
