Honestly - I think it must be a laptop thing. I have a similar spec laptop [0] for work, and it's... borderline unusable. I can ignore the upsells, always online, etc but the OS is just fundamentally falling apart more and more every other release. If I unplug the power cable, it throttles itself to the point of being neutered, and if I try to put it to sleep it _very regularly_ will just stay awake and drain its own battery.
My work desktop on the other hand (i9, 64GB ram, 4080 GPU) is absolutely screaming and I have some of the same problems but they're nowhere near as bad.
I don't think I could genuinely buy another windows laptop.
