The new Ryzen 9000s had poorly arranged internal cooperation and took longer than necessary. The new BIOS update solves this and latencies drop to the ground.
For a processor with many cores, it is important how quickly the cores can communicate with each other. All the more so when they are used by a program that counts on multiple cores/threads. But when internal communication drags on, instructions between cores take a nap, what does that mean? That the desired result is also delayed. And that concerned the new Ryzen 9000s, which had internal latencies 2x higher than the predecessor Ryzen 7000 (sometimes over 200ns).
But don’t despair, a fix is on the way and somewhere in the world. For example, Asus has already released a new AGESA 1.2.0.2 firmware for boards with 600 chipsets (X670, B650) and it fixes the lazy processors. Users reported that before using the update CPU latencies were 180ns, after the application they dropped to 75ns.

It also helped synthetic benchmarks, for example the score in Cinebench R23 increased by 400 to 600 points. Taken that way, it looks like a huge performance upgrade, but in normal use you probably won’t even notice it. But as you can see, the Ryzen 9000s are still working at two-thirds of their capabilities, because even the recent Windows 11 24H2 update added about 10% more. Who knows how they will be in half a year.
