The Beta BIOS with the AMD AGESA 1.2.0.2b patch seems to be working great for Ryzen CPUs in gaming applications. The results show better 1% lows over the previous BIOS patch.
AMD AGESA 1.2.0.2b brings the Core Tune Config feature that reduces memory latency and improves performance in games for Ryzen CPUs
With the release of the AGESA 1.2.0.2a patch for AMD Ryzen CPUs, many users complained about high memory latency. While AMD did work and fixed the high inter-core latency on the AMD Strix Point APUs recently and also the inter-core latency on Ryzen 9000 desktop CPUs a few months back, the 1.2.0.2a patch increased the memory latency.
Thankfully, the upcoming BIOS patch AGESA 1.2.0.2b is reportedly able to fix this issue on AM5 motherboards along with enhancing the system performance noticeably. The YT channel Compusemble shows the results comparing the benchmark numbers as yielded from using the AGESA 1.2.0.2a vs 1.2.0.2b patches. The test bench includes the AMD Ryzen 7 9800X3D, 64 GB (2x 32 GB) G.Skill Flare X5 DDR5 6200 MT/s CL30, ASUS ROG Strix B650E-F Gaming WiFi, and RTX 4090 GPU.
The performance increment was consistent across several games, which included titles like Hitman 3, Spider-Man Remastered, Cyberpunk 2077, Starfield, and several others. As the AGESA 1.2.0.2b features a new feature called Core Tune Config, which when set to Legacy mode, the results are noticeably better.
We can see that the games can achieve up to 6.52% higher average fps compared to the previous 1.2.0.2a patch. The difference can be anywhere from 1-7% depending on the games. Moreover, the 1% lows have drastically improved, even better than the average fps, making gaming more smooth and enjoyable.
As mentioned in the results, this was achieved via BIOS 3065 Beta, which isn't yet official. Currently, you can only download the BIOS 3057 for this particular model, which comes with the AGESA 1.2.0.2a patch. However, the latest one should come out in a few days. One more thing to point out here is that the 1.2.0.2b patch shows improved memory latency as tested by the user in AIDA64 Extreme. As mentioned in the intro, the memory latency decreased to 64 ns from over 68 ns. This is similar to pre-AGESA 1.2.0.2a patch latency.
