AMD has rolled out a new BIOS update this week, which adds official support for a 105W TDP (Thermal Design Power) for the Ryzen 7 9700X and Ryzen 5 9600X processors. This update, based on AGESA 1.2.0.2, not only introduces support for the new energy profile but also ensures that these CPUs are covered under warranty when using this TDP range. This means users can safely select the new TDP settings without risking warranty void if a component fails.
Additionally, the update addresses a long-standing issue with **communication latency** between the cores of Ryzen 9 9900X and Ryzen 9 9950X Processors, which feature two CCDs (Core Complex Dies). These two CCDs must communicate with each other, and the latency between them has been a point of criticism.
With the new update, AMD claims to have reduced the number of transactions by half, which significantly improves the core-to-core communication speed, especially on CPUs with multiple CCDs. According to AMD, this optimization has been a key focus since the launch of the Ryzen 9000 series.
How does an update affect performance in practice?
When AMD initially released the 105W TDP profile for the Ryzen 9 9900X and Ryzen 9 9950X, it faced criticism from the community, who felt the performance gains were minimal and barely noticeable. Many argued that the increase in performance was not significant enough to justify the new profile.
This time, AMD preemptively addressed these concerns, explaining that not every benchmark will reflect major improvements in performance and core-to-core latency. The company clarified that the real benefits are more noticeable in everyday usage and specific workloads.
While the performance boost might not be dramatic in standardized tests, AMD emphasized that users will likely see improvements in practical scenarios, particularly in tasks that leverage multi-core capabilities and require better communication between the CCDs.
“The improvement (in core-to-core latency) is most notable in very specific scenarios in games, especially those that use many threads and do not activate core parking. Our laboratory tests show that Metro Exodus, Starfield and Borderlands 3 can show some improvement, as well as synthetic tests like 3DMark Time Spy.”
How to update the motherboard?
The latest AGESA 1.2.0.2 update is now ready for download. To unlock the new 105W TDP setting for your Ryzen 7 9700X or Ryzen 5 9600X, head to your motherboard manufacturer’s official website.
Once there, go to the Support section, find your specific motherboard model, and download the newest BIOS version available. Simply follow the provided update instructions, and you’ll be all set!
