The company version of AMD’s Ryzen Card was launched on August 31, as the next step in AMD’s cavalry of new models. The pros card is called Ryzen Pro.
Unlike Ryzen, launched a little steadily, the entire Pro fleet comes at once. The Pro series consists of six different models. (See image below for basic comparison.) We were in Manhattan in New York when the new series was launched, where we also got an insight into the latest addition to AMD’s professional graphics series – Radeon Pro SSG.
The reason for Ryzen Pro is the same as previously introduced Ryzen in terms of; AMD’s SenseMi, Precision Boost, Extended Frequency Range and Neural Net Prediction, as well as support for ECC and more.
However, the promotional models have new integrated security features. Something AMD likes to talk about and compare with Intel competitor.
“Today’s security has come to a position where the feature should be a matter of course and not an option that end customers need to pay extra for,” says Kevin Lensing, CVP and GM for client computing at AMD.
What Kevin aims at is that Intel’s entire i3 series, including the i5-segment input model, lacks integrated security features.
In Ryzen Pro, we can divide the security solution into four main areas: GuardMI, which is the name of the technology itself, TSME memory encryption, Windows 10 integration where Ryzen Pro, the first processor, supports all of the Windows 10 Enterprise classified security capabilities as well as support for fTPM and TPM2.
But what’s really TSME?
To get a basic understanding of TSME, which has its foundation in the Zen architecture’s encryption technology, we will try for a simple explanation. We compare with traditional memory management.
Many today use encryption on their connections and on the data stored on local disks. However, when this data is moved from disk to processor and memory, this happens in unencrypted format. It allows third parties to access and listen to this data, a risk becoming even greater with newer NV memories that retains data even after power is turned off.
Through Secure Memory Encryption or short and good SMEs, one of two technologies in the Zen architecture, a dedicated 128-bit AES encryption engine is used for both reading from and writing to memory, reducing the risk of data coverage. As always, when it comes to encryption, it takes part of the processor’s resources. According to AMD, this should be limited to a maximum of three percent of the total capacity, which must be considered a relatively reasonable price to pay for the increased security.
