Power envelopes are reported in very misleading ways by companies, in practice it is not even close. The way they report stuff is having their cake and eat it too: the benchmarks results assume boosting their frequencies above the base one, while the "power envelopes" advertised are on the base frequency. It becomes quite apparent when you run them on battery, where M1/2s continue performing the same as plugged in, and amd/intel laptops underperform, while also not even lasting as much as apple's on battery.
