Lenovo ThinkStation P920 Tower Power Load Tests
Power consumption can vary a significant amount depending on processors used and the number of HDDs/SSDs/Expansion cards used. Here we test just a primary system. We test with the same graphics cards and NVMe SSD in all our tests. Power is measured at the wall.
For our tests, we use the AIDA64 Stress test, which allows us to stress all aspects of the system. Our Lenovo ThinkStation P920 Tower Review pulled 933watts at the wall when under full load and idled at 165watts. Dual Quadro RTX 8000’s in NVLINK generate more power use when stressed vs. a single GPU. Our Dual Xeon Gold 6234 CPU’s idle at a lower wattage then Dual Xeon Platinum 8260’s results in lower idle power use.
- OS Idle: 162W
- AIDA64 Stress Test: 933
The cooling system of the Lenovo ThinkStation P920 Tower Review did perform well, and fans did noticeably spin up at higher loads. Fan noise was low at idle, and even during moderate workloads, it was hardly noticeable, during peak workloads the fans could be heard but not at the extreme levels we have heard with other manufacturers 4U workstations. We had no issues sitting next to the system while testing.
That is important since these systems often need to sit desk-side where loud systems can hinder both the employee working on them as well as those around them.
We took a fairly extensive look at the ThinkStation P920. That means we tested a configuration through a number of different workloads. If, for example, you were not bound by per-core licensing, then the Xeon Gold 6234’s found in this unit would not have made as much sense as some of the newer and higher-core count Xeon offerings. Overall, the pairing of the Quadro RTX 8000 GPUs with dual Xeons positions this at the top-end of Lenovo’s workstation range, even with the new Lenovo ThinkStation P620 being announced.
As one might expect, a Lenovo ThinkStation P920 Tower configured as our review unit is pricey, with a base price as it was equipped for our review of $39,899! That is sticker shock for sure. However, on Lenovo’s website, we spot significant savings that can be found at a discounted price of $27,929. For those who have corporate purchasing deals with Lenovo, and those who have a Lenovo sales rep, we may suggest that online pricing is often higher than street pricing once customary discounts are applied. Naturally, when one needs dual NVIDIA Quadro RTX 8000’s for work, these machines can be costly but make up for it in pure graphics horsepower resulting in increased productivity.
What sets the Lenovo ThinkStation P920 Tower above the pack is its complete tool-less feature set, it is a simple task to get inside the P920 and install or swap out components. The design of the P920 case is also a classic, simple, elegant, and even with its large size, it is an effortless task moving the workstation around with handholds in easy reach. One also gets the on-site service from Lenovo and if you are an existing Lenovo customer, this is an easy choice for this class of machine.
