Since the chips were introduced, gamers complained about stuttering issues in select video games. It appears the problem was caused by power management issues, AMD tracked down the culprit and coded general power management optimizations to resolve stuttering and improve performance.
Overclock3D reports the update targets the site's only major criticism of Raven Ridge, as it makes the overall gaming experience much smoother:
With AGESA version 1002a, AMD has made Raven Ridge's clock speed spikes a lot less aggressive, resulting in increased smoothness and an elimination of the Ryzen 5 2400G's sudden stutter problem. While this update doesn't force iGPU clock speeds to remain constant while gaming, the changes included in AGESA 1002a dips minimise their impact. Now clock speeds decrease by around 10% or so, rather than the 75+%, making the transition hard to spot given its momentary nature.
While this clock speed issue is specific to only a handful of games, this change has made Raven Ridge a much more viable gaming chip at stock clock speeds by providing a smoother overall gaming experience.
AGESA 1002a BIOSes are coming out now for Ryzen 5 2400G & Ryzen 3 2200G with performance and smoothness improvements for PUBG, Overwatch, and Minecraft. Keep an eye on your mobo vendor’s download page. pic.twitter.com/zlgL4hs8YW— AMD Ryzen (@AMDRyzen) April 20, 2018
