I haven’t tried the amd mainboard yet but I have the 12th Gen Intel framework and the fan is capable of running very loud if you want to take maximum advantage of the processor performance.
Turning off turbo, running thermald etc can give you a more comfortable and quiet experience and longer battery runtime if you are prepared to give up that peak performance which is mostly not required. PC hardware sells on unsustainable peak performance tests thanks to the focus of reviewers on those numbers instead of the overall experience.
The Intel cpu gives much worse performance per watt than the m1 but the system it is in is also much easier to repair and upgrade and has much more mature open source support. It is a tradeoff.
I owned and enjoyed using an intel MacBook when they were serviceable and upgradeable. It had a long and productive life and was easily one of the best made laptops available in its time for the money. Framework might not be offering revolutionary CPUs but they make Apple’s business of selling disposable closed hardware look extremely dated. I would rather take a small performance hit until the rest of the industry catches up than spend any more of my time and money with Apple. Apple have more engineering talent and money than just about anyone which could be used to make ground breaking sustainable, repairable, open hardware and they always choose to go the other way.
I have to respect the Asahi devs for attempting to liberate apple hardware. Making systems more free is never a bad thing. It is unfortunate that systems even need to be liberated.
