New Ryzen chipset driver comes with new features and provides special gaming optimizations for the Ryzen 7000X3D series

At CES 2023, AMD unveiled three desktop processors featuring the Zen 4 architecture and 3D vertical cache technology, namely the Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D, all with a TDP of 120W and an increased L3 cache of 64MB. The Ryzen 9 7950X3D and Ryzen 9 7900X3D, both dual-CCD models, with only one CCD adding SRAM, will be launched first on February 28th.

AMD promises that it has collaborated with Microsoft to ensure that the Windows operating system can recognize the difference between the two CCDs and allocate tasks accordingly. According to VideoCardz, the new AMD Ryzen chipset driver can dynamically allocate the cores needed by the Windows operating system, which means that if the workload is cache-sensitive, the operating system will prioritize using the CCD with added SRAM.

AMD states that this feature will be controlled by the driver, but can be manually changed in the BIOS to allow users to choose according to their preferences. AMD also confirms that the same driver will have a PPM Provisioning File Driver, primarily for gaming workloads, which will dynamically allocate the CCX. If more threads are needed, the CCX without additional cache will also be enabled.

AMD claims that both features will improve performance according to workload, but the main purpose of these technologies is to enhance gaming performance. To be more specific, these features are targeted at the dual-CCD Ryzen 9 7950X3D and Ryzen 9 7900X3D, and the Ryzen 7 7800X3D, which only has one CCD, is not affected by this issue.
