I was not wrong when stating the C-State Boost Limit was not present with the hardware and BIOSes available at launch. This Precision Boost limiter is not active on retail processors. For the 16-core 7950X, the C-State Boost limit would force the CPU to run at 5.2 GHz when more than four cores are active.

Effectively, C-State Boost limits the maximum frequency when a certain number of active cores is exceeded. Some limiters are not relevant to a desktop system and may be ignored.Ĭ-state Boost is a specific boost limiter present on early engineering samples. While all these limiters are present on a Ryzen 7000 CPU, it does not mean they are all active or configured. Now, let us have a closer look at the Precision Boost infrastructure limiters exposed to the end user.

Here is what I had to say about this feature: In this quick article, I want to shed more light on the Precision Boost C-State Boost limiter I discussed previously in my Raphael launch blog.
