AMD Enhances Zen 5 CPU Latency and Performance with New BIOS Updates

AMD Releases BIOS Update for Enhanced Ryzen 9600X and 9700X Performance

AMD has unveiled a new round of BIOS updates aimed at optimizing the performance of its Ryzen 9600X and 9700X processors. This update is particularly timely, arriving shortly after some less-than-favorable reviews for the Zen 5 desktop CPUs. The improvements come hand-in-hand with updates to Windows 11 that feature optimized AMD-specific branch prediction for both Zen 4 and Zen 5 architectures.

Addressing Latency Issues in Ryzen 9000-Series

Various CPU reviewers have noted a higher-than-expected core-to-core latency across the Ryzen 9000-series processors. In response, AMD's latest BIOS update conditionally implements AGESA PI 1.2.0.2 firmware, which aims to tackle specific situations in multi-chiplet (CCD) designs where the processor has to generate two transactions for reading and writing data. AMD stated, "We’ve managed to cut the number of transactions in half for these scenarios, which helps significantly in reducing core-to-core latency."

Boosting Performance with 105-Watt cTDP Option

The newly released BIOS update introduces a 105-watt configurable Thermal Design Power (cTDP) option for the Ryzen 9600X and 9700X processors. According to AMD, "These processors were validated at 105W since launch, ensuring that you won’t be pushing them beyond their designed limits." This enhancement is especially advantageous for multithreaded applications but can also yield performance gains in less-threaded workloads.

Cooling Requirement for Enhanced Performance

Users looking to enable the 105-watt mode must ensure proper cooling systems are in place, but AMD guarantees that this performance boost will not void the warranty on the processors. The expectation is to see up to a 10% increase in performance.

Launch of New AM5 Motherboards

Additionally, AMD is rolling out its latest AM5 motherboards, the X870 and X870E, which are now available at retailers. While these new boards aren’t necessary for the Ryzen 9000-series CPUs, they do support several cutting-edge features: USB 4.0 comes standard, and both boards include simultaneous PCIe 5 Gen 5 support for graphics and NVMe interfaces. With speculation surrounding the upcoming RTX 5090 being a PCIe Gen 5 card, having this support is vital for users.

DDR5 Memory Support Upgrades

The X870 and X870E boards also boast support for higher-clocked memory, with AMD enabling DDR5-8000 EXPO compatibility. This new setup promises latency improvements of around 1 to 2 nanoseconds compared to the previous DDR5-6000 configurations.

Conclusion

With these updates, AMD is not only addressing performance and latency concerns but also positioning itself strongly in anticipation of a new generation of graphics cards. Enthusiasts and gamers can look forward to significant performance enhancements with proper hardware configurations.
