That’s true but keep in mind this is the power going into the AMD CPU only. The power number measured for the mini was the entire system power pulled from the wall, so that 28W included memory, conversion inefficiencies and everything. That’s crazy.
- JAlexoid 6y agoWhen we get to the detailed comparisons - it's almost impossible to compare without deconstructing the chips. In the end it'll be a question of - can Apple scale it without incurring massive costs?
- adrian_b 6y agoActually a significant power, maybe around 20 W, is consumed by the I/O chip, which consumes a lot because it is made in an old process. In 2021, when the laptop Zen 3 will be introduced, that will have a much better power efficiency, being made all in 7 nm. Of course, it will still not match the power efficiency of M1, which is due both to its newer 5-nm process and to its lower clock frequency at the same performance.
