This is false, in cross platform tasks it's on par if not worse than latest X86 arches. As others pointed out: 2.5h in gaming is about what you'd expect from a similarly built X86 machine.
They are willing due to lower idle and low load consumption, which they achieve by integrating everything as much as possible - something that's basically impossible for AMD and Intel.

May have been true when CPU manufacturers left a ton of headroom on the V/F curve, but not really true anymore. Zen 4 core's power draw shoots up sharply pass 4.6 GHz and nearly triples when you approach 5.5 GHz (compared to 4.6), are you gonna complete the task 3 times faster at 5.5 GHz?
