I have not had any problems on my end. I do know that for encoding, there are some quality issues with AMF when comparing it against Nvidia and Intel at equivalent bitrates that was only resolved with the latest 90xx series, but for Jellyfin purposes it works perfectly fine.
I prefer AMD over Intel because for 3D acceleration, AMD wins hands down. I also like AMD CPUs over the absolute power-hungry heaters that are Intel CPUs because it allows me to use lower profile coolers and cheaper PSUs.
Some lab and manufacturing equipment are still stuck on incredibly old versions of Windows. However, the thought of those machines still touching the Internet to the point where it can be counted by these statistics is honestly terrifying.
