AMD will begin selling the Ryzen 9000 CPU in early August, boasting the Zen 5 architecture with up to 16% higher instructions per cycle (IPC) compared to Zen 4. However, various hardware review websites have pointed out that the performance of the Ryzen 9000 hasn’t seen a significant increase from the Ryzen 7000 as advertised.
AMD has addressed this through a company blog, clarifying two key points:
Firstly, the performance metrics showcased by AMD during the launch event differ from those measured by reviewers due to the complexity of the tested games, hardware components, and Windows configurations. AMD affirms the accuracy of their own results, ensuring no deception or falsehood.
Secondly, the Zen 5 CPUs are designed with improved branch prediction capabilities compared to previous Zen architectures, potentially impacting Windows operations. As a result, AMD has collaborated with Microsoft to optimize Windows 11 code to support branch prediction architecture. This adjustment may lead to up to a 13% increase in performance in certain games, as tested with the Ryzen 9 9950X. Additionally, this code optimization may slightly enhance the performance of Zen 3 and Zen 4 CPUs.
This latest update has begun rolling out in the Windows Insider Program (Release Preview Channel – Build 26100).
TLDR: AMD introduces Ryzen 9000 with Zen 5 architecture, emphasizing higher IPC. However, reviews indicate minimal performance gains compared to Ryzen 7000. Collaboration with Microsoft to optimize Windows 11 for improved branch prediction may enhance CPU performance.
