    I see the problem, but I don't see a clear analysis on the actual source of the problem. I assumed the issue was mainly single core performance, but he is also suggesting context switches could be the cause?

    So could you fix that with a new scheduler? Or you just need another SoC with better single core performance? I could imagine that the latter already exists, just not in soc with >16 cores.

    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.

    Can the ThinkPad T14 ARM Snapdragon variant function without pain as a daily Linux/BSD driver?

      No. It can run Windows well though.

      Snapdragon has excellent single-thread performance (unlike Ampere) if that’s what you’re asking.

      Without pain? I mean, there is pain when using Linux. It just works better than, say, Windows.

    The Desktop Linux will take over from here guys. Next year it will be ready, together with GNU Hurd for everyone and their Grandma.
