AMD Reinstates CPU Encryption After Backlash

AMD has reversed its decision to remove Transparent Secure Memory Encryption (TSME) from its consumer Ryzen CPUs, following considerable public outcry. This security feature, also known as Memory Guard, encrypts data in system memory, thereby protecting against physical intrusion methods like cold boot attacks. The feature was unexpectedly removed through a recent firmware update, sparking criticism from users who had come to rely on it for over a decade.

In response to the community's strong feedback, AMD stated it will reinstate the option to enable Memory Guard in an upcoming BIOS release planned for July 2026. The company has not yet provided a detailed explanation for the initial removal. Speculation ranges from an attempt to encourage purchases of more expensive 'Pro' models to performance considerations, as encryption can introduce latency.

TSME operates by transparently encrypting and decrypting all data passing through the processor to and from physical memory. This protection is OS-independent, making it relatively easy to implement. While it can incur a slight performance cost, the risk for typical consumer systems is often considered lower than for business or high-security environments. AMD's move to restore the feature after customer complaints has been acknowledged as a positive response to user feedback.
