AMD Ryzen 7000X3D processors require a special driver to function correctly

AMD Ryzen 7000X3D processors equipped with the optional 3D V-Cache can automatically optimize performance based on the current workload. To support this feature, AMD will release a new driver for X670/670E and B650/650E motherboard chipsets.

The new chipset driver number 5.01.03.005 can dynamically select the preferred Ryzen 7000X3D processor core to which the Windows scheduler sends the load first. In other words, if the performance of a certain software is more dependent on the amount of available cache memory, in this case the operating system will prioritize the use of cores that have additional 3D V-Cache cache memory. When processor frequency is more important to performance, the cores with the highest clock speed are chosen.

The company explains that this feature is controlled automatically by the chipset driver, but can also be configured manually via the motherboard’s BIOS. Users can choose between cache priority or clock speed at will.

AMD has confirmed that the new chipset driver will also include a PPM Provisioning File Driver feature. Its main purpose is to dynamically select Ryzen 7000X3D CCX blocks equipped with 3D V-cache and to park CCX blocks without additional 3D V-cache for gaming workloads. However, if you need access to a larger number of computing threads in a given game, all the CCX blocks will be used at once.

According to the company, both of the above features are designed to improve the performance of processors depending on a specific load. However, their main purpose is to improve gaming performance.

It is important to note that these optimizations only target the 16-core Ryzen 9 7950X3D and 12-core Ryzen 9 7900X3D as they are the only ones in the Ryzen 7000X3D series to feature an asymmetric cache set. These processors have two CCD chiplets, but only one of them is equipped with an additional 3D V-cache, which makes it have a lower frequency. The eight-core Ryzen 7 7800X3D, on the other hand, has only one CCD chiplet, so it does not need any additional optimization of the CCX units.
