Alongside every launch of AMD’s consumer processors, the commercial offerings for business come along a few months after. Today we see the commercial launch of the Ryzen 5000 Mobile series, named Ryzen Pro 5000 Mobile. These are built on the same Cezanne processor design, but with the added sprinkling of Pro level features required by commercial customers for widescale deployment, security, and stability. Alongside the increased performance from the previous generation, these new parts include the security updates in Zen 3 such as Shadow Stacks, Pro-level features such as DASH, and guaranteed silicon and imaging support.

The new Ryzen Pro 5000 Mobile processors are all 15 W components, with up to eight cores, sixteen threads, and boost clocks up to 4.4 GHz. As with the non-Pro counterparts, these are using the latest updates to AMD’s Vega design enabling higher frequencies through design co-optimization with TSMC.

While the hardware underneath is similar, AMD’s marketing messages around its commercial product offering cater to a more business oriented crowd. Metrics such as maintaining productivity, keeping focus, allowing for remote work and collaboration, combined with performance, power efficiency, security, and scalability, all enter into that ecosystem.

To that end, AMD is promoting it is expecting 63 commercial platform designs with its new processors, enabling 3x growth since the 2018 product portfolio. AMD believes this new generation, at 15 W, performs favourably to Intel’s 28 W quad-core Tiger Lake offering, roughly on par in single threaded performance but from 23% to 65% higher performance in multi-threaded workloads. Separately to this, AMD is also promoting +1.5 hours of battery life compared to Ryzen Pro 4000 Mobile.

In the new product family, Cezanne enables several key updates compared to the previous generation.

The move from Zen 2 to Zen 3 is the biggest uplift, offering +19% more performance through a new core design enabling higher throughput as well as cache changes. For Ryzen Pro 5000 Mobile, there is double the cache, from 8 MB to 16 MB, but also it is a unified cache, allowing all eight cores to access all 16 MB. This enables an effectively lower latency in that memory banding, which is also coupled with an improved memory controller offering double the memory support (up to 64 GB DDR4-3200, up to 32 GB LPDDR4X-4266). The memory controller also supports lower power operation for better battery life.

Also on the angle of battery life, the new processor design now allows for per-core voltage through tighter on-chip power regulation. This allows all eight cores and the graphics to operate at independent voltages and frequencies, allowing the processor to optimize where the power needs to be for a given workload, and reduce power during idle times. This is coupled with an upgraded power and response automation, allowing for the most efficient cores to be used for light tasks, faster performance bursts in response-limited scenarios, and more precise voltage/frequency control for the processor.

For the graphics, while it is still Vega 8 graphics, the design has been optimized for a higher graphics frequency. Coupled with the memory controller updates, AMD is promoting better graphics performance and acceleration in typical commercial workloads that can take advantage of this.

Security updates are of note in the new processors, with AMD implementing its control flow enforcement technology for protection against stack return and jump attacks – you may see this advertised as AMD’s Shadow Stack technology. AMD’s Pro security stack also enables the integrated security processor for a secured core PC, also coupled with FIPS encryption certification as a government standard.

The usual AMD for Business / AMD Pro Business Ready ecosystem is still in play for the new Pro 5000 series. This includes 18 months image stability, 24 months guaranteed processor availability, enhanced QA and validation of the silicon to ensure the best parts, and continuous long-term stability checks.

System Offerings

AMD was keen to promote 63 commercial systems coming to market this year with Ryzen Pro, mostly 4000 and 5000 series parts. Six models were given as part of the launch briefing, three each from HP and Lenovo:

  • HP Elitebook 845 G8
  • HP Probook Aero 635 G2 (AMD exclusive)
  • HP Probook x360 435 G8 (AMD exclusive)
  • Lenovo Thinkbook 16P (AMD exclusive)
  • Lenovo Thinkbook 14S
  • Lenovo Thinkpad T14S

Commercial products often take time to come into market, especially with large scale deployments. It will be interesting to see the mix of designs compared with the regular Ryzen 5000 family.

    Any of these offerings with 16:10 or 3:2 displays? Reply

    There should be some 13" Thinkpads with 16:10 displays and Ryzen 5000. Reply

    I'd like to see someone (ASRock? Supermicro?) use these Ryzen Pro 5000 CPUs in a _desktop_ motherboard, like AOpen used to do with its "MoDT" motherboards. Features I'd want: ECC RAM support, four full-size DIMMs, multiple PCIe slots wider than x1 (v3.0 fine with me). Bonus points if could be powered with 19VDC rather than ATX PSU. Reply

    Why not just get a desktop APU? If you want lower power consumption, just set it to one of the lower cTDP levels in BIOS.

    19VDC power would also be somewhat problematic when coupled with PCIe slots, as you'd need to convert at least 75W of 12VDC for each x16 slot, and 25W for each x1 slot, necessitating some pretty beefy on-board VRMs. Of course you can just buy a HDPlex PSU setup to power pretty much any pc off 19V.

    Ryzen Pro 5000 desktop CPUs not yet released AFAIK...
    Want Pro for DASH remote-management ability without need (and power draw) of separate BMC.
    How low can cTDP (of say, 4750GE) go?
    Point taken about PCIe power needs, though power-restricted slots would still be useful.

    Will there be Trade Agreements Act (TAA) Compliant APU SKUs? Reply

    In the US, systems with the 4800u are hard to find, whereas the pro 4750u is available from lenovo. I wonder how constrained the chip supply will be this generation.

    Next gen do they switch to ddr5 and rdna2?
