According to new latest testing, the latest AGESA (AMD Generic Encapsulated Software Architecture) update, version 1.2.0.2, promises a significant boost in performance for AMD Ryzen 9000 “Zen 5” processors. This update is targeting one of the most crucial aspects of multi-core processing: inter-core latency. The AGESA 1.2.0.2 update addresses challenges initially reported in AMD’s Zen 5 architecture, particularly in scenarios demanding rapid communication between multiple cores. Early reports suggest a remarkable reduction in inter-core latency by up to 58%. According to Overclock.net testing, older AGESA 1.2.0.1A showed the cross-CCD latency at around 180 ns. However, with the new AGESA 1.2.0.2 BIOS, the latency is seemingly around 75 ns…

AMD AGESA PI 1.2.0.2 Performance With The Ryzen 9 9950X On Linux

There has been a lot of talk the past few days over the AMD AGESA PI 1.2.0.2 update that has begun rolling out to AMD AM5 motherboards with BIOS updates. The AGESA 1.2.0.2 is said to improve inter-core latency for Ryzen 9000 “Zen 5” processors when cores from different CCDs are cross-communicating. Some — at least under Windows — have reported performance improvements and thus several Phoronix readers have requested I run some of my tests with AGESA 1.2.0.2. Here are said comparison benchmarks using an AMD Ryzen 9 9950X on Ubuntu Linux…
