The updated chipset drivers from AMD divulge new functionality.
The performance of AMD Ryzen 7000X3D processors with 3D V-Cache will be automatically optimised based on a workload. The most recent chipset driver will have the ability to dynamically allocate which core the Windows operating system will use. In other words, the operating system will be changed to prioritise cores with 3D V-Cache if the workload is cache-sensitive. Higher frequency cores will be picked if frequency is more crucial.
The manufacturer states that although the BIOS allows for manual adjustment, the driver is responsible for controlling this feature. Users can choose between “cache” and “frequency” based on their preferences.
AMD also affirms that the PPM Provisioning File Driver will be included in the same drivers. As it will dynamically allocate CCX using 3D V-Cache and park unused CCX without additional cache, this feature is particularly intended for gaming workloads. The CCX without 3D V-Cache will also be enabled if more threads are required.

According to AMD, these innovations will boost performance based on the workload, but their primary goal is to improve gaming performance.
It’s crucial to keep in mind that they are intended for Ryzen 9 7000X3D CPUs (7950X/7900X), as only these two out of the three disclosed SKUs use an asymmetric chiplet design, where one CCX features 3D V-Cache and the other does not. The single chiplet 8-core Ryzen 7 7800X3D, which will go on sale in April, does not have this issue.
