AMD Ryzen 9 7950X 16-core processor exhibits some strange behavior with regards to the max boost frequency spread among its cores. A multi-chip module with two 8-core CCDs (CPU complex dies); we noticed early on in our review that the cores located in CCD-1 boost to a higher frequency than the ones in CCD-2, with differences as high as 300 MHz. CapFrameX noticed that when CCD-2 is disabled, the processor actually puts out higher gaming performance, by as much as 10%. This is mainly because the cores in CCD-2, with a lower maximum boost frequency no longer handle processing load from the game; and with CCD-2 disabled, CCD-1 has all of the processor's power budget—up to 230 W—to itself, giving it much higher boost residency across its 8 cores.
 
A very interesting way to increase gaming performance

    Why doesn’t AMD use windows 11 to focus gaming performance on CCD-1 only? They could just call CCD-2 the efficiency core side of the CPU and CCD-1 the performance core, and be just like Intel.

    Interesting , but yeah, I assume it's just a software / coding problem that could be fixed.. but no one wants to take the time to do it.
