AMD has released new BIOS updates that aim to boost performance and address latency issues for its Ryzen 9600X and 9700X processors. These updates come about a month after disappointing reviews of Zen 5 desktop CPUs and alongside Windows 11 optimizations that include AMD-specific branch prediction enhancements for both Zen 4 and Zen 5 chips.
CPU reviewers have reported higher-than-expected core-to-core latency across the Ryzen 9000 desktop lineup. AMD's new BIOS optimization, based on AGESA PI 1.2.0.2 firmware, addresses this by reducing the number of transactions required to read and write shared data across different parts of the Ryzen 9 processor.
Notably, AMD is promising a 10% performance uplift on the Ryzen 9700X with a new 105-watt cTDP mode. This mode has been validated since the processors' release and won't void warranties, though users will need appropriate cooling to enable it. The performance boost is expected to be most evident in multithreaded workloads.
Alongside the BIOS updates, AMD is launching its X870 and X870E AM5 motherboards this week. These boards support USB 4.0 and simultaneous PCIe Gen 5 for graphics and NVMe storage - a feature that AMD suggests will be important as the next generation of graphics cards arrives. The new boards also enable DDR5-8000 EXPO memory support, which can provide 1-2ns of latency improvements over DDR5-6000.
