The new M4 MacBook Air is displaying unexpected behavior in terms of CPU workload allocation.
While editing photos in Lightroom Classic, it is utilizing the six efficiency cores and barely using the four performance cores, which is different from the M3 MacBook Air.
This behavior could potentially improve battery life and temperature management but its purpose or significance is not yet known.
It remains unclear if this is intentional or a bug, and further experimentation and analysis are needed to understand this behavior.
