I'm not surprised at the outcome. These Ampere system single core/thread performance is pretty low and that is where you feel it. The OS/software simply cannot allocate the threads across enough cores effectively to make up for this difference.

This is why things like the Apple M Series feels so fast, because while they don't win the multi core performance especially when going up against a 80 core beast like this, they have single thread performance exactly were it is needed.

Maybe we will need 80 cores in future, that is cool but for daily home use it is still just way too much for what we need.
