AMD details intermittent system stutter issue with Ryzen processors in Windows 10 & Windows 11

If you have a Windows 10 or Windows 11 PC with an AMD processor and feel like your system is running a bit slow, then you're not alone. AMD has published an article on its website, detailing an intermittent system stutter issue impacting systems with Firmware Trusted Platform Module (fTPM) enabled (via Neowin.)

According to AMD, the issue impacts select AMD Ryzen systems, which might intermittently perform extended fTPM-related memory transactions in SPI flash memory on the motherboard. This can lead to temporary pauses in system interactivity or responsiveness until the transaction is concluded. The fix is a motherboard BIOS update, that has updated and enhanced modules for the fTPM-related memory transactions. Unfortunately, though, the fix won't come until early May 2022 and will only be for motherboards based on AMD AGESA 1207 or newer.

As a workaround for this issue, AMD suggests using a hardware TPM device for trusted computing. These utilize onboard non-volatile memory (NVRAM) that supersedes the problematic SPI flash memory. AMD also points to this Microsoft webpage, which assists with TPM management and transfers.
