When we look at the front of the case, the first thing that sticks out are the four USB 3.0 ports, media card reader and headphone/ microphone jack. That is enough I/O to avoid running cables from the back of the tower to the desktop in most cases. We often see workstations with two front panel USB ports so this is a significant upgrade.

Here is a list of the ThinkStation P910 front ports and connections

  • Flex Bay with Optical installed
  • 2x Flex Bay empty
  • Media Card Reader
  • 4x USB 3.0 ports
  • Headphone Jack
  • Microphone port
  • Power button

We also see the HexPerf Honeycomb Design used on the ThinkStation line up.

We would like to see the orientation of the optical drive rotated 90 degrees. The way it is now, when you eject a DVD it can fall out and onto your desk if placed in a standard tower orientation.

Let us turn the case around and take a look at the back of the P910.

Overall, the dual LAN connections are welcome, as are the plethora of USB ports. Lenovo even adds legacy PS/2 keyboard and mouse ports along with a serial port.

Here is a list of ThinkStation P910 rear ports and connections

  • 1x audio line in, 1x audio line out, and 1x mic in.
  • PS/2 Keyboard and Mouse ports.
  • 1x Serial port.
  • 2x stacks with 1x LAN and 2x USB 2.0 ports.
  • 4x USB 3.0.

On the side of the P910, there is a locking lever which releases the side door. Let us take off the side cover and look inside.

Here we have taken the side cover off the P910 so we can get a peek inside. The first item we notice is the large Tri-Channel Cooling Shroud patented by Lenovo, which spans the middle of the case. This aids in cooling the CPU’s underneath. It uses fewer fans and helps reduce noise levels. We can see many red touch points in this picture, each highlight an access point for quick and easy component changes.

Moving on, let us take off the air cooling shroud and get a look at the CPU/RAM area underneath. Cooling fans at the front and back end of the case push air through the CPU heat sinks, boosted by additional fans mounted on the heatsink itself. Channels in the air shroud also direct air flow across the RAM sticks for cooling.

Here we take a closer look at the CPU heat sinks. Aided by the channeled airflow shroud, Lenovo can use a smaller heatsink that performs very well.


Let us take a look at the P910 BIOS. On startup, a message will come up that allows you to press “Enter” to enter the BIOS. You will then get a screen that allows you to select startup devices and other options, select enter BIOS to continue. Layout and content of the BIOS is very similar to the P410 we reviewed earlier.

Our P910 came equipped with two Intel Xeon E5-2620 v4 processors. These are not the fastest processors in the list of available processor options for the P910; they do offer a relatively large core count which will help in multi-threaded applications.

It also comes equipped with NVIDIA’s high-end Quadro P6000 which we took a look at on a separate review. There is no need to repeat all the graphics tests for this card, head over to our P6000 review to check those out.

Performance Tests and Benchmarks

Geekbench 4 CPU Benchmark

Each CPU workload models a real-world task or application, ensuring meaningful results. These tests are complex, avoiding simple problems with straightforward memory-access patterns, and push the limits of your system.

The Samsung SM961 1TB NVMe SSD installed in the flex module on our P910 and used as an OS boot drive generates impressive results.

Boot Time

BootRacer is an app that will tell you how long your computer takes to boot. It will measure the actual time your PC takes to get to Windows boot process, then measure the actual windows OS boot time.

BootRacer is a free download for personal use and can tell you if your PC is booting slower over time or after you have installed apps.

Booting up the P910 for the first time, we noticed it was very fast. In fact, one of the fastest booting dual processor systems we have used. Our everyday driver based on an ASUS TS700-E8-RS8 Workstation which uses a Z10PE-D16 WS motherboard and two E5-2699 V3 processors takes over a full minute to boot up!

We ran Bootracer on the P910 after we set everything up. No special BIOS settings were adjusted, BIOS set to default settings fresh out of the box. At 35 seconds for complete a system boot on this Dual-CPU based system is impressive.

Power Tests

For our power testing needs, we use a Yokogawa WT310 power meter which can feed its data through a USB cable to another machine where we can capture the test results. We then use AIDA64 Stress test to load the system and measure max power loads.

Our P910 configuration does not pull huge amounts of power under heavy load, coming in at close to 350watts even with all components except the OS Boot drive at maximum loads.


Top end workstations are always a pleasure to review here at STH. Over time we have used many different workstations from several manufacturers, each workstation has its pros and cons. These could range from being very hard to get inside the system for maintenance, adding new components, noise levels, and storage options. We feel the ThinkStation P910 has hit the sweet spot; it is a complete tool-less case which makes it a breeze to add drives, swap out PCIe devices or pull fans out for cleaning. Lenovo’s patented Tri-Channel Cooling solution not only cools the processors very well it also helps a great deal to remove noise.

Using the Flex-Module with a Samsung 1TB NVMe SSD improves system response. Most dual processor systems we use, boot in the range of a minute plus, our P910 booted in 35 seconds which was amazing to us. It boots as fast as many single processor systems or laptops that we use daily.

One of the other workstation specifications we first look at is the number of USB ports the system has; we use a large number of USB devices here in the lab which makes this an important feature to use. With 4x USB 2.0 and 4x USB 3.0 ports at the back and 4x USB 3.0 ports at the front fills our needs very well.

If audio outputs are important to you, we find the supplied rear audio ports to be lacking with only one output jack. An additional option to look at when customizing your P910 would be an independent audio card which has a Sound Blaster Z Audio add-in card or via USB 3.0 audio options.

Network options are relatively standard with 2x 1Gbps ethernet ports. There are more advanced network adapters available as purchase options. We would like to see 10GbE options available.

The bottom PCIe device area of the case is large and roomy. There is ample space to house two graphics cards, and case fans provide airflow. This area is large enough to handle longer GPU’s such as our ASUS ROG Strix GTX 1080. These are big cards which might interfere with the Flex Module if you use one.
