Geekbech is as useful as a metric as an umbrella on a fish. Also the M4 max will not consume less energy than the competition. That is a misconception arising from the lower skus in mobile devices. The laws of physics apply to everyone, at the same reticle size the energy consumption in nT worlkloads is equivalent. The great advantage of Apple is that they are usually a node ahead and the eschewing of legacy compatibility saves space and thus energy in the design that can be leveraged to reduce power consumption on idle or 1T. Case in point, Intel's latest mobile CPUs.
