AMD's Ryzen Pro Processor Lineup Revealed

Security and Reliability




Ryzen Pro CPUs offers built-in hardware-based AES 128-bit encryption. The encryption offers two features, Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV). SME and SEV are also found on EPYC CPUs, and they provide real hardware based security. For SME a key is generated on boot up and isn't visible to the OS or software applications, and it can be used to secure a portion or all of the memory.



Intel has something similar, but it only encrypts a secure enclave inside the memory. SEV offers the ability for the hypervisor and guest user to secure part of themselves so that neither can see everything in the other, it's traditionally done with the hypervisor seeing everything of the virtualized guest, but this method provides the guest with some security as well.




The question of whether or not the hardware-based AES engine would hamper security did come up during the special briefing sessions. While it will have an impact, that impact is said not to be too system intensive, so you hopefully won't see a real-world performance drop. AMD's security also offers a secure booting process, support for fTPM and TPM 2.0, and AMD says it's production environment is secured from outside threats.




AMD offers 18-month image stability, a full two years of processor availability, highest yield wafer selection, and DASH manageability. These features are very important to enterprise clients, and with Intel's strong foothold in the business and enterprise market AMD does need a trick up their sleeve to get their foot in the door, and that is Ryzen Pro's security and reliability.




AMD is also making Ryzen Pro compatible with the AM4 platform. They are saying that AM4 will be around for at least 4 years and compatible n-2, n-1, and n+1 generations. All the processors will have a 36-month warranty for Ryzen Pro parts instead of the 12 months consumer processors receive. There is also no artificial differentiation, and AMD made a point of showing the i3 crossed out, as Intel does provide more features for higher-end products. AMD is providing all features to all products.
