AMD has launched its Ryzen 9000-series processors, introducing the Zen 5 CPU architecture. Reviewers have faced challenges in achieving expected performance levels, prompting AMD to clarify discrepancies noted before the launch. The upcoming Windows 11 24H2 update will include optimized AMD-specific branch prediction code, expected to improve performance by 3 to 13 percent in various games, also benefiting Ryzen processors based on Zen 3 and Zen 4 architectures. This update is anticipated to be available this fall, with current builds allowing performance improvements in Administrator mode. AMD has indicated that an update to chipset drivers could resolve some performance issues, particularly related to a "core parking" feature in the Ryzen 7900X3D and 7950X3D processors. This feature aims to optimize performance by activating cores with access to the 3D V-Cache. However, the drivers may inadvertently keep parking cores across all Ryzen 9000 CPUs, and the only resolution currently is to reinstall Windows. AMD has also suggested adjusting the processor's SoC voltage and Infinity Fabric clock speed for optimal performance with DDR5-6000 memory. Additionally, AMD noted that performance discrepancies may arise from variations in testing configurations among reviewers.
