100% chance its chewing through at least 50% more power to achieve the result.

Infact based on their TDP guidance, it goes up to 120w, which is more than double M4. But we don't know what the configuration was for this benchmark. We also don't have great numbers for M4's power consumption either.

Then you throw in the fact 120w TDP from AMD is not actually a power consumption figure... and it's all made up.
