Standard bios might allow a slight OC of a few % but not worth the effort. Modded bios would allow you to turn it up much more, if you can live with the new problems it brings.
Without a modded bios you can usually get by with a very small increase in the bclk before gross instability occurs. I mean like maybe 200-202.
What type of problems?
Would the AVX hinder gaming performance? I don't think the others are to important.I'm a bit rusty so you'll have to research in case I missed any, but the biggest ones to me are that AVX is broken (it still works, but slowly) and you lose access to the on-CPU per-core monitoring. I think the overall CPU temp is still present, unless it is something else measured by mobo... think there was something about losing power saving states but I don't think that to be a major problem.

Now idk about Intel, but I run my AMD chip full frequency 24/7. Can Intel not do that?
Sure, you can do it if you want but it will make more heat.
Probably not. For example, Ryzen is similarly weak in that department, and Celeron/Pentium level CPUs don't have it at all.
I run my Intels 24/7 with Prime95 like loads. My power bill is less fun.
