In addition to the above-mentioned fixes/improvements, the AGESA 1.2.0.1 BIOS Firmware also addresses the L3 cache performance issue that users were facing when updating to 1.2.0.0 BIOS Firmware. For that purpose, a test setup with an AMD Ryzen 9 5950X CPU and an MSI MEG B550 Unify motherboard was used. The comparison was done with both the AGESA 1.2.0.0 and the new AGESA 1.2.0.1 firmware. You can see the comparison in L3 Cache performance below:
