This does not address wether the GPU throttles in high CPU usage scenarios.
That being said, RAM and storage is pretty negligible. LPDDR4/X uses around 0.2-0.5w, and around 0.1-0.05w for storage.
There is also no reason to compare to Intel. The competition for Macs aren't older macs - newer macs are always going to be better than older macs. The competition is to what they could have been if they went for AMD, and to other computers of similar form-factors.
In both cases, you're comparing to AMD, not Intel.

With regards to performance and power consumption, AMD is not far ahead of Intel. Yes, they have better performance when you factor in all the Intel "bugs" like branch predition, but it's only about 10%-20%, and TDP is more or less the same.
Comparing it to a M1 will yield the same results. The lowest TDP i can could find was 65W for a Ryzen 3, which is still long way from M1 in both power consumption and performance.

Why are you comparing AMD desktop processors with laptop processors on power efficiency? That's incredibly contrived.
Compare the 5900HS with the M1, which is a 35W SoC, just like the M1, and much, much faster than any Rzyen 3.
Compare it to the previous (Intel) generation that uses 20W idle and 122W under load, while not matching the M1 in neither CPU nor GPU performance.
