AMD’s highly anticipated Ryzen 9000 desktop processors made their debut earlier this month, and while enthusiasts were excited about the performance improvements, initial reviews showed a different story. The gaming performance didn’t quite meet the expectations set by AMD’s marketing statements. So, what went wrong?
After a thorough investigation by reviewers and AMD, it was revealed that several factors contributed to the discrepancy in results. In a recent community post, AMD pointed to differences in Windows testing mode, VBS security settings, Intel system configurations, and the specific games used for benchmarking as key factors.
To shed light on the issue, David McAfee, who leads AMD’s client channel segment, joined The Full Nerd for a special discussion. The conversation delved into the intricacies of how AMD tested their processors compared to how reviewers did, highlighting the importance of testing methodologies and configurations.
One major revelation from AMD’s post was the impact of branch prediction optimizations in the ‘Zen 5’ architecture, which were not fully reflected in the initial benchmarks due to testing in ‘Super Admin’ mode. McAfee explained that this mode was essential for AMD’s automated testing framework but inadvertently created a performance disparity compared to standard user modes.
Looking ahead, AMD hinted at future performance improvements with Windows 11’s upcoming feature update “24H2,” which will align more closely with the testing conditions that AMD utilized. McAfee emphasized that while Super Admin mode was necessary for internal testing, it was not suitable for gaming environments.
The evolution of AMD’s testing framework over previous generations led to an oversight in the performance differences between different testing modes. McAfee acknowledged this blind spot and assured that corrective measures had been implemented to avoid such discrepancies in the future.
Another factor explored was the influence of game selection and specific scenes on benchmark results. McAfee elaborated on how varying CPU and GPU loads within games could significantly impact relative performance between different products, emphasizing the need for comprehensive testing methodologies.
In response to speculations about blaming reviewers for the discrepancies, McAfee clarified that the differences arose from AMD’s testing decisions rather than any faults in the reviewers’ processes. He commended reviewers for their thorough evaluations and acknowledged the complexities that led to divergent conclusions.
The interview with McAfee provided valuable insights into AMD’s testing practices, configuration choices, and the factors contributing to the Ryzen 9000 performance evaluations. It highlighted the importance of understanding the nuances of benchmarking and the significance of transparent testing methodologies.
