From The Verge: AMD is releasing new BIOS updates that will boost performance for its Ryzen 9600X / 9700X processors and address some latency issues. The performance improvements and latency reductions arrive around a month after disappointing Zen 5 desktop CPU reviews and appear alongside updates to Windows 11 that include optimized AMD-specific branch prediction for both Zen 4 and Zen 5 chips.
CPU reviewers have been reporting a higher-than-expected core-to-core latency across the Ryzen 9000-series of desktop processors, and now AMD has addressed this with a new BIOS optimization.
The latest AMD updates for AM5 motherboards include AGESA PI 1.2.0.2 firmware, which AMD says will address some “corner cases” where it takes two transactions to read and write when information is shared across different parts of a Ryzen 9 9000 processor. “We’ve managed to cut the number of transactions in half for this use case, which helps reduce core-to-core latency in multi-CCD models,” says AMD.
