You can create a lot of problems if you change the motherboard or the CPU and you do not reinstall Windows. I always do a fresh install whenever making any major hardware changes.
Anytime the number of cores and threads is not being reported correctly in the Task Manager, the first thing to do is run msconfig and check to make sure the Number of processors box is
not checked. This box should never be checked. Windows does not automatically update the number of cores and threads after a major hardware change. It is up to you to run msconfig and take care of this problem.

Most of the tech dudes working at places like Best Buy have probably never heard about this issue either. Now you know.
When i disable turbo the ring edp other goes away
When you disable turbo, the ring runs slower, it consumes less power and it needs to flow less amps. That is why the EDP throttling problems goes away when turbo boost is disabled.
My 12100f has no problems at all with ring edp other limit, it's just not as fast as a 13400f
A slower CPU with fewer cores and threads needs less power and current to run at full speed. A slow CPU will have less reason or no reason to EDP throttle.
Now you know that there was no reason to do that. Your CPU was fine. Windows was not setup correctly after installing your new CPU.
Intel started using EDP ring throttling on many of their 12th Gen and newer non K series CPUs. This new trick forces the ring to run slower than the cache. Intel CPUs also use a feature called Ring Down Bin which is usually enabled by default. Ring Down Bin forces the ring to always run at least 300 MHz slower than the core.
At default settings, my 10th Gen 10850K also runs the ring slower than the core so Intel has been doing this for a while now. The default multiplier when all cores are active is 48 for the cores and only 43 for the ring. Setting IccMax to a low default value for the ring is a new technique that Intel is using but slowing down the ring is nothing new. It forces the ring to run slower than the core. This is done deliberately to improve stability.
With unlocked K series CPUs, the ring ratio is adjustable, the Ring Down Bin feature is adjustable and IccMax is adjustable for both the core and the cache. This lets a person run their CPU however they like. The 13400F that you were using is a locked processor. No FIVR adjustments of any kind are available when a CPU is locked.
My best guess is that 14th Gen will be exactly the same as 12th or 13th Gen. The non K CPUs will continue to have locked IccMax. It will likely be set low and this will probably cause constant EDP ring throttling. Consider buying an unlocked 14600K. That should allow you to bypass EDP ring throttling as long as your B760 board does not lock out any FIVR adjustments.
