New “Zen 3” workstation processors feature higher performance per core and up to 64 cores and is available through the Lenovo ThinkStation P620 workstation
In summer 2020, AMD announced the Threadripper Pro 3000 WX-Series of processors for single socket workstations.
Based on AMD’s ‘Zen 2’ architecture, the CPUs combined high core counts, high frequencies and high memory bandwidth with pro technologies for security and manageability.
Threadripper Pro 3000 WX gave AMD a long-lost seat at the table of the major workstation manufacturers.
It marked the launch of the Lenovo ThinkStation P620, the first AMD-based workstation from the big four of Dell, HP, Lenovo and Fujitsu in almost 15 years.
18 months on and AMD has now launched its next generation, the Threadripper Pro 5000 WX-Series.
The Threadripper Pro 5000 WX-Series offers the same number of cores as its predecessor (12 to 64) but takes advantage of Zen 3’s higher Instructions Per Clock (IPC), as well as higher frequencies. This gives the workstation CPU a performance uplift in both single threaded workflows, such as CAD, and multi-threaded workflows, such as rendering, simulation and reality modelling.
Like its predecessor, the Threadripper Pro 5000 WX boasts 8 channels of DDR4 (ECC) memory, giving a significant benefit over consumer Ryzen processors in bandwidth hungry applications such as Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA).
There are a total of five Threadripper Pro 5000 WX-Series processors. The top-end Threadripper Pro 5995WX has 64 cores, 128 threads, a base frequency of 2.7 GHz and a boost of up to 4.5 GHz. There’s also the 32-core 5975WX, the 16-core 5955WX, the 12-core 5945WX, plus a new 24-core model, the 5965WX. As core counts drop, base frequencies increase but the 4.5 GHz turbo remains the same.
As with first generation Threadripper Pro, the new processor is available initially in the Lenovo ThinkStation P620 workstation. However, AMD has stated that other partners will be introducing workstations using AMD Ryzen Threadripper Pro 5000 processors later this year. We wonder if this will include Dell or HP, who continue to rely solely on Intel CPUs for their workstations.
For the launch of the new processors, AMD pointed out that Threadripper Pro is not just about hardware. The team also works closely with software development partners to help deliver ‘continuous performance enhancements.’
AMD highlighted improvements made to simulation software Ansys Mechanical that delivered a significant performance uplift. According to AMD, Ansys Mechanical v2021.R2 with optimised AMD BLIS CPU libraries is up to 2.3x faster than Ansys Mechanical v2021.R1 when run on the same AMD Ryzen Threadripper Pro 3995WX workstation.
There have also been improvements in rendering engines Autodesk Arnold and Chaos V-Ray, plastic flow simulation software Solidworks Plastics, and AI-assisted design tool PTC Generative Design. We expect more to follow.
Threadripper’s biggest competitor is currently the Intel W-3300 series of processors, which feature between 12 and 38 cores. Based on Intel’s ‘Ice Lake’ scalable platform, these single socket processors launched back in July 2021, but have not been taken up by any of the major workstation manufacturers. According to AMD, this is because it does not deliver the enterprise class features of the Threadripper Pro 5000 WX-Series.
In fact, some of the ‘mid-range’ workstations on sale at the moment, such as the Dell Precision 5820 and HP Z4 G4, feature ‘Cascade Lake’ Intel processors which date back to 2019. It is only entry-level workstations, such as the Dell Precision 3660 Tower and HP Z2 Tower G9 that feature modern Intel CPUs, but these are “Alder Lake” Intel Core and are limited to 8 cores.
With its ThinkStation P620, this currently puts Lenovo at a huge advantage when coveting customers whose workflows will benefit from a significant number of cores.
However, with the possibility of Dell or HP introducing AMD Ryzen Threadripper Pro 5000 workstations later this year, and with the expected launch of Intel’s new “Sapphire Rapid” CPU, it remains to be seen how long this lasts.
