AMD's New Ryzen 8000G APUs Will Soon Get A Sweet Speed Boost Via Firmware
Except, as it turns out, AMD may not have quite done its due diligence when preparing the firmware for these desktop CPUs, and everyone's reviews are probably at least a little bit wrong. You see, AMD's mobile processors have a technology called STAPM, or Skin Temperature Aware Power Management. STAPM is designed to manage the processor's performance to keep not only the chip's thermals in line, but also to prevent the outside (or "skin") temperature of the device from getting too high.
You're probably thinking "okay, but what does that have to do with a desktop CPU?" Well, nothing! Or at least, it shouldn't. But it does, because AMD forgot to disable STAPM when it ported these potent processors for portables over to the desktop platform. As a result, the Ryzen 8000G CPUs actually lose performance over time as the buggy STAPM feature, lacking the proper inputs, engages and throttles the chip after a heavy load.
This behavior was discovered by Gamers Nexus (video embedded below), and that site praised AMD's response to its discovery by noting that the manufacturer quickly moved to address the issue and assure GN that a fix would be forthcoming. Such a fix will be in the form of a firmware update, which means you'll have to get a motherboard BIOS update from your board manufacturer to resolve the issue.
