1) M1 is significantly faster than 4800U at single-core. 2) M1 is up to 20 hours of battery life. 3) Not the software since the existing Intel based Macs shar

  M1 is somewhat slower in multicore, and has a fifth of the I/O performance. They are comparable. Importantly, you're comparing the M1 in a Mac Mini, to the 4800U in a laptop. Comparing the M1 in the Air, for example, the 4800U is quite a bit faster in multicore and the single core performance advantage shrinks. As for 2 and 3, you're comparing to AMD, not to Intel. AMD CPUs have significantly better power efficiency than Intel. If you want to compare battery life without taking into account software, compare power consumption. The Zen chip uses slightly more power than the M1 on a laptop.

    >As for 2 and 3, you're comparing to AMD, not to Intel. AMD CPUs have significantly better power efficiency than Intel. Still nowhere near as the same battery life has been seen in any AMD laptop. Not even in ones with less perf. Seems that you're grasping at straws at this moment :-)

      No I'm not. I'm specifically considering two chips. Those Macs have both much better software for power management, and much more battery. You can't compare chip power consumption by comparing total endurance of the system. When you do compare the two, they're within 30% of one another.
