Hands on: I tested the Lenovo ThinkStation P620 Tower – see what I thought of this cheap workstation

We haven’t seen many blue-chip brands in our workstation Labs for some years. This has largely been because these manufacturers stuck with Intel Xeons, even when AMD was in the ascendancy, so wouldn’t have fared well. But Lenovo has been offering the AMD alternative for some years and was the initial partner for the Ryzen Threadripper Pro when it arrived last year. Now we get our first look at what Lenovo can do with this potent CPU.

The system is based on the AMD Ryzen Threadripper Pro 5945WX, which has the lowest number of cores of any CPU this month – just 12. These run at a base 4.1GHz and boost 4.5GHz, with multithreading and support for eight-channel memory. But Lenovo only provides four 3,200MHz DDR4 DIMM modules, so the bandwidth is quad channel with half the throughput of eight-channel, even though the total was a wholesome 64GB.

Lenovo offers a choice of AMD and Nvidia graphics with the P620, and our system came with Nvidia’s RTX A4000. This places this configuration as a modelling workstation rather than more general purpose. Lenovo was IBM’s hardware manufacturer, and when IBM became a services company Lenovo inherited its server and workstation business. The chassis is still reminiscent of the former brand, with excellent tool-free design.

In this high-powered company, the P620 fell behind, achieving 529 in the media-focused benchmarks, 21,580 in the Cinebench R23 multicore rendering test and 486 seconds for the Blender CPU render. These would have been amazing scores a year ago, but all other systems here are way ahead. The Adobe Media Encoder results were impressive, however, taking 121 seconds with CUDA acceleration enabled.
