Have I just had bad luck with my AMD products?
I've had four Nvidia GPU/Intel CPU computers with no issues.
I've had three AMD GPU/AMD CPU computers and they all have been loud and hot and slightly unstable. A bit cheaper sure, but I rather have a silent and stable experience.
This has made me see amd as the inferior lowbudget crap. But maybe I have just bought from the wrong manufacturer or something.
I can't speak of older stuff, but my Ryzen 5 5600x and RX 6800 have been great. I've had this pc for a year now, and only have had the GPU drivers crash twice. That is about on par with my older gtx 1070
Maybe, because cpu wise amd should be doing better than intel on heat and power consumption. Loud would have to do with the cooler you choose and wouldn't be a function of the cpu itself. Aftermarket coolers are often better than stock and not that pricey, but will want to look into reviews for a quiet one. Amd had been cleaning intel's clock the past few generations in cpu performance. Intel has finally caught up again and is slightly ahead in power this gen, though amd still winning a lot in efficiency and power consumption/heat and still has the best gaming cpu. Good summary here.
In terms of gpu that's gonna vary widely depending on what specific gpu and what configuration of that gpu you're buying. Before buying I would look into specific reviews of that manufacturer if you can and not just the stock gpu itself, because every one is going to have a different configuration and fan/cooler setup for the gpu. Unfortunately gpus from both amd and Nvidia are becoming more and more power hungry giant heat generating monsters over time.
This is the general trend in my roughly two decades of having my own PCs, so your mileage may well vary, especially since some series of both CPUs and GPUs were just better/more compatible with each other than now or the other way around.
In case anyone's curious, my current combo is
Ryzen 7 3800X and RTX 3060.
You have almost the same setup as I do right now.
3900x and a 3080.
Took me four cpu fan switches until I could stand being in the same room. Stock fan, sounded like a drying cabinet. BeQuiet, loud. Noctua, less loud but still loud. Im using a radiator now with silentwing fans and it's still slightly too loud for my taste (and louder than any Intel I've ever had).
Temps seem to be in normal range though.
I went with idiotproof watercooling for the CPU and a mid-range quiet-type cabinet and it's whisper-quiet and well within optimal temperature range even at high load.
Ive only ever used amd gpus and intel cpu, and the only hardware issue ive had is one gigabyte card having a firmware bug that killed it. amd always worked great on windows for me, but on linux they suffer from crashing quite often.
