AMD has quietly removed memory encryption from its consumer-grade processors. The change affects the company's latest desktop and laptop chips, though AMD has not publicly explained the decision or disclosed which specific models are impacted.
What memory encryption did
Memory encryption scrambles data stored in RAM so that even if an attacker gains physical access to the machine, they can't read sensitive information like encryption keys or passwords. AMD's implementation, called Secure Memory Encryption (SME), was a hardware-level feature introduced in its EPYC server chips and later brought to consumer Ryzen processors. It allowed users to encrypt the entire system memory with a single toggle in the BIOS.
Without that protection, anyone with physical access to a computer — a thief, a border agent, a repair technician — could potentially extract data directly from the memory modules. The feature was especially valued by people handling sensitive data on laptops, such as journalists, lawyers, and corporate employees.
What's left
AMD still offers other security features on its consumer chips, including Secure Encrypted Virtualization (SEV) for virtual machines and Platform Security Processor (PSP) for boot protection. But the removal of SME means the most straightforward, system-wide memory encryption is gone. Users who want similar protection now have to rely on software-based solutions, which can slow performance and aren't as comprehensive.
The company hasn't said whether the removal is permanent or if it will return in a future generation. It also hasn't explained why the feature was dropped — cost, performance trade-offs, or low adoption are all possible reasons, but AMD hasn't confirmed any.
What users can do now
For now, anyone who needs memory encryption on a consumer AMD system is out of luck. Intel's consumer chips still offer Total Memory Encryption (TME), a similar feature. Some users may consider switching to Intel hardware, but that's not an option for those already invested in an AMD platform.
Security-conscious buyers should check the specifications of any new AMD system before purchasing. The company's product pages and datasheets may not always clearly state whether SME is present. A BIOS update could also remove the feature from existing systems, though AMD hasn't announced any such update.
The move leaves a gap in AMD's consumer security lineup. Whether it's a cost-cutting measure, a simplification of the chip design, or a response to low usage, the result is the same: one less layer of hardware protection for millions of users.
