Word is going around that the AMD AGESA Combo-AM4 v2 update contains optimizations that lower the inter-core latency. Tests performed by CapFrameX and ComputerBase user Verangry reveal the update delivers quite significant improvement in core-to-core latency and core-to-core bandwidth.

This is valid for the Ryzen 3000 "Matisse" processors and Ryzen 4000G "Renoir" APUs. CapFrameX shows an improvement from core-to-core latency of 56.9ns with AGESA Combo V2 1002 to 48.9ns with AGESA Combo V2 1081. ComputerBase also reports performance gains of 3 to 7 percent in this area.

Furthermore, it seems chips like the Ryzen 3950X are able to hit their max Boost frequency more often with the latest AGESA microcode.
