Ryzen 7 7800x3d - CPPC Dynamic Preferred Cores or Collaborative Processor Performance Control
Hello!
Well, after buying the 7800x3d I was testing the bios of my B650 Plus Wifi Version 3072, and I came across the CPPC Dynamic Preferred Cores or Collaborative Processor Performance Control option, it has: (Auto) (Frequency) (Cache) (Driver), I can't get it find documents about
I play Fortnite and I'm not sure how each option actually works... and which option would be ideal for lower latency/game speed
I thank you in advance guys!!

CPPC defined in the ACPI spec describes a mechanism for the OS to manage the performance of a logical processor on a contiguous and abstract performance scale. CPPC exposes a set of registers to describe abstract performance scale, to request performance levels and to measure per-cpu delivered performance.

It allows for prioritizing core scheduling and is beneficial primarily for dual-CCD X3D processors where one CCD has the extra 3DvCache and the other CCD has higher frequency boost.
On single CCD processors like your 7800X3D using this feature has mixed results, I would leave it on the default setting.
