"The TDP of the [AMD 5850U] APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor (most chips are configured higher than 15 Watt)." [1]

I'd love to see actual measurements for both chips.

Yep, you can see the distribution of results (there aren't a lot) here and it's all over the place for the Ryzen vs M1 :

M1 : https://www.cpubenchmark.net/cpu.php?cpu=Apple+M1+8+Core+320...

TDPs don't mean anything even within a vendor lineup, and doing cross comparison is futile (without properly measuring yourself the power consumption at load, then you can start doing real efficiency comparison or apple to apple).

Also, Intel and AMD chips are allowed to greatly exceed those TDP numbers with as much as 50-60 watts peak consumption.
