That combination of decent performance (even while unplugged), battery life, and silence is hard to come by in x86 laptops, even in ultraportables built with efficiency-focused laptop CPUs where one would expect at least battery life and fan noise to not be issues.
Apple’s silicon helps here but I wonder if part of the problem isn’t x86 laptop manufacturers trying too hard to juice perf numbers at the cost of all else, as well as penny pinching on heatsink and fan.
