You can do "ECO mode" pretty easily on the Intel platform too--two seconds to type a power limit in BIOS. And the results should be similar. W1zzard actually wrote a whole article about Alder Lake's power scaling, which is worth a read. It showed that the chips' power efficiency goes through the roof if you dial back the limit. I dare say that dialing back the power limit by at least a few dozen watts is a worthwhile option for almost every reader here, because the performance differences will be small even in the worst case (full, all-core workloads), and non-existent in the vast majority of cases (lightly threaded workloads); the cooling difference, by contrast, will be considerable.Even if the cpu rendering lasts several hours and not two days, the power consumption and the high temps that come with it are a problem for all the people who care of the energy bill and of the room temperature. We live in a time where summers last longer and have higher temperatures: depending of what one does with his pc, that is something to care about before buying the cpu. The Ryzen chips with the ECO mode seem a better choice for the people who will keep their cpu on the limit for most of the time. That or they move to Alaska.
I don't mean to suggest that I approve of either AMD or Intel pushing their default power limits to the sky just to eke out a few extra percentage points on review benchmarks, but it is what it is, and I have a hard time getting worked up over this one aspect of Intel/AMD's highly competitive posture, because otherwise their tight competition is a huge boon to consumers. Still, it would be nice to see all hardware manufacturers put a little more emphasis on out-of-the-box efficiency.
