AMD AGESA 1.2.0.2 Update Fixes Ryzen 9000 Series Inter-Core Latency Issues
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.
Interestingly, the update has arrived on the ASUS ROG Crosshair X670E motherboard, with BIOS version 2401. BIOS updates with the latest AGESA 1.2.0.2 are still rolling out, so it will be interesting to see further testing and possible improvements. It could be that the cross-CCD latency has just been reported badly, so final testing will conclude the latency increase from Zen 4 to Zen 5 debate.

I'm no expert, this is a serious question. I wanna know.
Theoretically. Latency matters a lot for gaming workloads. How much this will pan out in practice in terms of actual frametimes is up in the air.
On release the 9k series will be stable and first day error fixed.
EDIT: Checked it on OCN (where I am a regular member as well) and its on the CCD cores only.
Not exactly sure why hardware companies are giving people beta firmware and drivers. These are all well known benchmarks and something AMD should have been able to prioritize. Intel's screwing up big but it's nice that AMD makes sure that Intel can be seen in the best light based on the current circumstances.
Not a big deal
I think far too many people have forgotten this. There is always some growing pains when you are doing something new.
Everyone seems to be on the release first patch after boat.
But obviously there was a massive uproar over this with people claiming this bug reduces performance drastically bla bla.
Good thing they fixed it I suppose.
Do we have a similar "map" for Threadrippers?
