AMD-based systems still suffer from performance issues due to the Trusted Platform Module (TPM) that is integrated into most modern systems. One of our readers reported encountering something similar on their Zen 2 based PC. The PC in question was powered by a Ryzen 7 3700X and a Radeon RX 5700 XT on a X570-A PRO motherboard. The primary symptoms include intermittent stuttering reported during gaming workloads.
The user provided us with a 3DMark report of their system and we confirmed their findings. The AMD X570 platform faces usage and frequency decreases on the GPU side at certain benchmark points. Frame rates go haywire on these exact time frames, confirming the findings. AMD has acknowledged this problem to the user and claims that firmware updates are the solution. However, most people claim otherwise.
This report is a bit unexpected as this system is using the newer version TPM 2.0 solution. AMD’s official statement blames the problem on extensive fTPM-related memory transactions in SPI flash memory. It resides on the motherboard, causing temporary pauses in system interactivity or responsiveness until the transaction is completed.
