PulseAudio optimizes for power consumption but tries to be adaptive to handle lower latency as well. PipeWire seems to optimize for latency but try to be adaptive to reduce power consumption as well. These are conflicting desires, lower latency requires higher power usage because you have to use shorter buffers instead of just giving the sound card a big chunk of audio to work through and putting the CPU to sleep. JACK could potentially still do better and ALSA could potentially still do better than even that but PipeWire's goal is to be close enough or even match JACK while still having all the other features people use PulseAudio for.
