AMD Ryzen PRO Mobile APU Key Features

AMD GuardMI Technology

Even though the Ryzen PRO APU uses the same silicon as its consumer-grade siblings, it has AMD GuardMI Technology enabled.

GuardMI is built into the silicon, which offers OS-agnostic security through :

  • Transparent Secure Memory Encryption – DRAM encryption with minimal performance impact
  • Secure Boot Process – hardware-based root of trust secures the BIOS from power-on
  • Real-Time Intrusion Detection – with support for fTPM and TPM 2.0


Enterprise-Grade Reliability

The AMD Ryzen PRO APU will come with enterprise-grade reliability features like :

  • 18 months of planned software stability
  • 24 months of planned processor availability
  • commercial-grade quality-assurance process
  • cherry-picked silicon for long-term reliability and performance
  • supports DASH manageability standard
  • 36-month limited warranty for system manufacturers


Single CCX Configuration

Unlike the Summit Ridge-based Ryzen CPUs, the AMD Raven Ridge processors use a single CCX configuration. This is a cost-saving measure with a much smaller die size, that also yield some performance benefits – reduced cache and memory latencies.


Precision Boost 2

The AMD Ryzen PRO APU also boasts the improved Precision Boost 2, whose more graceful and linear boost algorithm allows them to “boost more cores, more often, on more workloads“. It is now able to change frequencies in very fine granularity of just 25 MHz.

According to AMD, this will allow the AMD Ryzen PRO APU to perform better with apps that spawn many lightweight threads, as opposed to apps with persistent loads (e.g. video editing and 3D rendering).

Mobile XFR (mXFR)

Mobile XFR (eXtended Frequency Range) is the automatic overclocking feature that boosts the processor voltage and clock speed beyond the Precision Boost clock speed. It leverages the temperature awareness of Precision Boost 2 to determine how much faster it can overclock.

Like the desktop XFR feature, it is highly dependent on the processor temperature, so a good cooling solution is necessary. Notebooks must have coolers that meet AMD’s performance criteria if they want to offer mXFR.


Synergistic Power Rail Sharing

The AMD Ryzen PRO mobile APUs have a unified VDD power rail with digital low-dropout (LDO) regulators. This synergistic power rail sharing allows the maximum current requirements to be reduced by 36%.

They also have multiple digital LDO regions for the CPU cores, graphics core and subregions. This allows those regions to be completely turned off when they are idle, greatly saving power.

The shared voltage regulators not only reduce the total current draw, it allows the Ryzen PRO mobile APU to gain a higher peak CPU and GPU current to boost performance.
