AMD is reinstating memory encryption for its consumer CPUs following user backlash over the silent removal of the feature, known as Transparent Secure Memory Encryption (TSME). This encryption protects against physical attacks by encrypting data stored in memory. Originally, TSME was included in both high-end and lower-end Ryzen processors but was removed without warning in a firmware update. The company faced criticism and decided to restore the feature in an upcoming BIOS update scheduled for July.
Critics speculate reasons for the removal may include steering customers toward more expensive CPUs or performance issues, as some gamers preferred to disable encryption to reduce latency. AMD's removal of TSME, previously a feature users expected, sparked significant community outcry, underscoring a broader issue of corporate accountability.
