While Lunar Lake has excellent energy efficiency and AMD does not really have any CPU designed for low power levels, Lunar Lake had also a very ugly hardware bug (sporadic failure of MWAIT to detect the waking event).
This bug has disqualified Lunar Lake for me, and I really do not understand how such a major bug has not been discovered before the product launch (the bug has been discovered when in many computers running Linux the keyboard or the mouse did not function properly, because their events were not always reported to the operating system; there are simple workarounds for the bug, but not using MONITOR/MWAIT eliminates one of the few advantages that Intel/AMD CPUs have over Arm-based CPUs, so I do not consider this as an acceptable solution).
