The AMD Ryzen PRO Desktop APU Tech Report

The AMD Ryzen PRO Desktop APU Tech Report

AMD just announced the availability of seven Ryzen PRO APU models for the mobile and desktop markets, as well as laptops and desktops featuring these new APUs. Get the full details of the new AMD Ryzen PRO desktop APU – features, specifications and availability!

 

AMD Raven Ridge

Raven Ridge is AMD’s codename for their Ryzen-Vega APUs (Accelerated Processing Units). First introduced in the mobile segment as the AMD Ryzen Mobile, AMD is now offering PRO versions in both mobile and desktop markets.

These Ryzen APUs combine an AMD Ryzen CPU, with an AMD Radeon Vega GPU, in a single die.

Ryzen CPU + Radeon Vega GPU = Ryzen APU

Desktops APUs are not new. AMD have been making them for years, and many Intel desktop processors come with integrated graphics. But AMD is still the only manufacturer to integrate “premium CPU cores” with “premium graphics cores”.

 

AMD Ryzen PRO Desktop APU

The AMD Ryzen PRO desktop processors, revealed in September 2017, were enterprise-grade versions of the first-generation AMD Ryzen 7 and Ryzen 5 processors. A month later, AMD launched the AMD Ryzen Mobile APUs.

However, AMD has not launched any enterprise-grade APU for either the desktop or mobile market… until now, that is. Here are the first seven AMD Ryzen PRO APU models – three for the mobile market, and four for the desktop market.

AMD Ryzen PRO APU (Mobile SKUs)

  • AMD Ryzen 7 PRO 2700U – 4C/8T, 2.2 to 3.8 GHz, Vega 11 Graphics, 15W cTDP
  • AMD Ryzen 5 PRO 2500U – 4C/8T, 2.0 to 3.6 GHz, Vega 8 Graphics, 15W cTDP
  • AMD Ryzen 3 PRO 2300U – 4C/4T, 2.0 to 3.4 GHz, Vega 6 Graphics, 15W cTDP

AMD Ryzen PRO APU (Desktop SKUs)

  • AMD Ryzen 5 PRO 2400G – 4C/8T, 3.6 to 3.9 GHz, Vega 11 Graphics, 65W TDP
  • AMD Ryzen 5 PRO 2400GE – 4C/8T, 3.2 to 3.8 GHz, Vega 11 Graphics, 35W TDP
  • AMD Ryzen 3 PRO 2200G – 4C/4T, 3.5 to 3.7 GHz, Vega 8 Graphics, 65W TDP
  • AMD Ryzen 3 PRO 2200GE – 4C/4T, 3.2 to 3.6 GHz, Vega 8 Graphics, 35W TDP

In this article, we will focus on the Ryzen PRO desktop APUs. For the AMD Ryzen PRO Mobile APUs, we have a separate article – The AMD Ryzen PRO Mobile APU Tech Report.

AMD Ryzen PRO Desktop 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.

Smaller L3 Cache

Using a single CCX configuration halves the Raven Ridge L3 cache size from 8 MB to 4 MB. To compensate, AMD increased their base and boost clock speeds.

 

New CPU Package

The Raven Ridge APUs also introduce a revised CPU package, and a switch to the traditional non-metallic TIM (thermal interface material). These are again cost-cutting measures, albeit with a side benefit of allowing the Raven Ridge processors to officially support DDR4-2933 memory.

 

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).

 

PCIe x8 For Discrete GPU

The Summit Ridge-based AMD Ryzen 7, Ryzen 5 and Ryzen 3 processors have 16 PCI Express 3.0 lanes dedicated to the PCIe graphics card. In Raven Ridge, that gets cut down to half. That means any external graphics card will only communicate with a Raven Ridge processor at PCIe x8 speed.

This is a cost-saving measure, making the Raven Ridge processor simpler and cheaper to produce. AMD also claims that the move contributed to a smaller and more efficient uncore.

AMD Ryzen PRO Desktop APU Performance

We haven’t had the opportunity to benchmark these desktop APUs, but they should perform similarly to the consumer-grade Raven Ridge desktop APUs we reviewed earlier :

Let’s take a look at some benchmark results that AMD shared with us.

General Office Productivity

In general office productivity apps, the AMD Ryzen PRO 5 2400G was just under 90% as fast as the Intel Core i5-8400. The AMD Ryzen PRO 3 2200G, on the other hand, was slightly faster than the Intel Core i3-8100.

Professional Applications

Thanks to the integrated Vega Graphics, the AMD Ryzen PRO desktop APUs shine in professional applications. The AMD Ryzen PRO 5 2400G performed up to 2.8X faster than the Intel Core i5-8400. The AMD Ryzen PRO 3 2200G, on the other hand, was up to 2X faster than the Intel Core i3-8100.

 

AMD Ryzen PRO Desktop APU Availability

The AMD Ryzen PRO desktop APUs (and Ryzen PRO Mobile APUs) are already available to OEMs, with AMD announcing the following designs for both SME businesses, as well as enterprises.
