AMD Resolves Ryzen 9000 Inter-Core Latency with AGESA 1.2.0.2 Update

AMD has recently taken significant steps to address performance issues in their Zen 5 “Ryzen 9000” CPUs. Users reported high inter-core latencies, especially when communicating between different Core Complex Dies (CCDs). This led AMD to release the AGESA 1.2.0.2 BIOS update, aimed at optimizing performance and resolving latency concerns.

Initial Issues with AMD Zen 5 “Ryzen 9000” CPUs

Performance Drawbacks and Latency Concerns

Technical reviewers initially found significant performance drawbacks with the AMD Zen 5 series, most notably due to high inter-core latencies. Communication latencies between different CCDs reached 180-200ns, which marked a noticeable increase compared to the previous Ryzen 7000 “Zen 4” series. This escalation in latency significantly impacted the performance of the CPUs, particularly in multi-threaded applications where efficient inter-core communication is crucial. The fluctuations in latency appeared prominently during benchmark tests, signifying deeper issues within the new architecture of the Zen 5 CPUs. These findings alarmed many users and reviewers, who expected the latest series to build upon the strengths of its predecessors.

The increased latency adversely impacted the overall performance of multi-threaded applications. Users and reviewers noticed that tasks requiring intensive communication between different CCDs were particularly affected, leading to sub-optimal functioning not only in synthetic benchmarks but also in real-world applications. The performance shortcomings were not just theoretical; they manifested in everyday tasks, causing frustrations among users who had upgraded to the new series expecting seamless performance. Such issues prompted AMD to seek immediate rectifications to ensure that their flagship CPUs met user expectations and retained competitiveness in a rapidly evolving market.
