AMD Introduces New AGESA BIOS For Ryzen 9000 Series Amid Performance Backlash

Expert Verified By

AGESA 1.2.0.2 Update Aims To Fix Performance Issues!

Story Highlight
  • AMD introduced a 105 W TDP option for the Ryzen 7 9700X and 9600X with full warranty coverage, enabled through the latest UEFI firmware.
  • The AGESA 1.2.0.2 update reduces core-to-core latency by 60% for dual-CCD Ryzen 9000 CPUs, with only slight real-world performance improvements.
  • Official support for DDR5-8000 RAM is introduced, along with new AM5 motherboards featuring enhanced I/O capabilities.

Today, AMD announced significant announcements regarding its desktop Ryzen 9000 series CPUs, which are built on the Zen 5 microarchitecture. The primary goal is to enhance the August product launch.

Why it matters: The addition of a 105 W TDP option and improvements in motherboard features increases flexibility for users, allowing them to choose configurations that best suit their needs. 

For starters, AMD revealed a 105 W TDP option with full warranty coverage for the Ryzen 7 9700X and Ryzen 7 9600X processors. The AGESA ComboAM5 PI 1.2.0.2 microcode, the most recent UEFI firmware version on a motherboard, can be used to enable this setting in the BIOS.

With this latest AGESA upgrade, AMD has also fixed a core-to-core delay issue. According to AMD, this update is an attempt to optimize for a “corner case” situation. That being said, this modification has been found to offer a 60% latency reduction in testing.

However, this patch affects only the Ryzen 9000 CPUs with dual-CCD, such as the 9 9900X and 9 9950X. According to AMD, this update only slightly improves “real-world” performance.

Thanks to the latest AGESA version, official support for DDR5-8000 EXPO RAM modules is now available for AMD AM5 motherboards. It should also be noted that even though DDR5-8000 is faster than DDR5-6000, DDR5-8000 support requires a 1:2 UCLK: MCLK ratio to function on AM5.

While DDR5-6000 operates at a 1:1 ratio, the advantages of increased memory speeds on the DDR5-8000 memory modules are offset by slower UCLK speeds. However, a 1:1 UCLK: MCLK ratio can enable memory rates greater than DDR5-6000. However, not every CPU can support these faster speeds.

AM5 motherboards based on the AMD X870E and X870 chipsets are now available. They offer better I/O features like 40 Gbps USB4, Wi-Fi 7 networking, and Ryzen 9000 support out of the box.
