AMD has released its new AGESA 1.2.0.1 BIOS that will add a number of important enhancements that will benefit Ryzen 5000 processors.
AGESA 1.2.0.1 now arriving in public BIOSes for Ryzen 5000 Series!
1) Fix: False SMART errors on Hynix NVMe
2) Fix: Intermittent SSD detection for M.2 SATA devices
3) Improve L3 $ bandwidth in AIDA64
4) Improve stability if user disables cores on 5600X / 5800X with AMD Ryzen Master pic.twitter .com / KqGu78rqiE

AMD has been working hard to improve support for Ryzen 5000 processors and also to fix a number of flaws that could alter performance, such as bandwidth and L3 cache latency.
The red team has improved the bandwidth and latency of the L3 cache on the Ryzen 5000 processors by around 25%. This change alone is worth this update.
According to these L3 cache tests performed on a Ryzen 9 5950X, the bandwidth of the L3 cache goes from 1,200GB / s for reads to 1,319GB / s, and from 800-850GB / s for writes to 1,100GB / s when overclocking to 4.5 GHz. This is an increase of almost 30% for L3 write speed and 10% for read speed.
In this way, thanks to AGESA, 1.2.0.1, the same speed can be achieved simply by activating the PBO and increasing the EDC. Cache-dependent workloads should see an interesting performance boost.
AMD also takes the opportunity to fix some M.2 SATA SSD detection problems and false SMART errors on NVMe Hynix drives. In addition, the stability of those deactivated cores of the Ryzen 5600X and 5800X with AMD Ryzen Master is improved.
AMD seems to strive to eliminate all the edges that may be left on the Ryzen 5000 processors, which have been a great success for the company. We will keep you informed.
