I went from an i5-7600K to an i5-13600K and the performance improvement has been worth every penny. Obviously a bit of a different upgrade than what you asked so it’s hard for me to say if it’s worth it in your case.
That being said the significant upgrade in core count has helped a ton, I usually have around 30 docker containers running and haven’t had any performance issues, previously my whole server would lock up when any docker ran an intensive process unless I pinned cores for unraid itself. Ive also seen a huge improvement with transcoding due to the improved iGPU but I think that was the same one in the 12th gen so you probably wouldn’t see value there.
I’d even be okay with patents lasting more than 5 years as long as the patented concept is being actively utilized. Essentially, use it or lose it.
