* Exactly how is it much better? It's not the first chip with a 15-25W TDP. When compared to other chips with such a TDP, it's incrementally faster in single core and it trades blows in multicore. It does this at a process node ahead.* Ok. Where can I buy a laptop with similar performance, battery life and cooling then? Same arguments came out with the first iPhone. “It’s just a big screen! Other phones have a big screen!”

Similar performance and cooling? Buy a Ryzen 4800U laptop. Similar battery life? A good part of it is down to the software, sadly. For the trade-off of 8 instead of 12 hours of battery life, you'll have a repairable and open computer. Seems competitive. You also get upgradeable RAM, a GPU that is actually useful because it has drivers for a useful API, and much more I/O.

  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 share the same OS.

    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.
