Lenovo didn’t want to be left out of the eGPU fun and made a surprise announcement at CES 2018 of its first Thunderbolt 3 Graphics Dock. This dock follows the growing trend of smaller footprint enclosures with external power adapters. The new Lenovo Thunderbolt 3 Graphics Dock reminds me of the Acer graphics dock from a year or two ago.
It didn’t take long to locate the dock once I got inside the Lenovo suite. I immediately went after the external power adapter. It’s surprisingly reasonable in size. I placed my iPhone SE on top of the power brick for scale. A helpful Lenovo representative answered most of my questions about the unit. The output is 170W. Power Delivery is 65W. The graphics card is a MXM GTX 1050 with 4GB of VRAM.
Here’s what I gathered on the Lenovo Thunderbolt 3 Graphics Dock:
- Dimensions: 130 x 248 x 22.6mm (5.12 x 9.76 x 0.89 in)
- Weight: 1.51 lbs (686 g) for the enclosure only
- Full-feature Thunderbolt 3.0 port: data, video & power delivery (65W)
- MXM GTX 1050 4 GB GDDR5 graphics card
- Up to three 4K displays: 1 x HDMI 2.0, 2 x DisplayPort 2.0
- 1 x always on USB 3.0, 1 x USB 3.0, 1 USB 2.0
- 1 x 3.5 mm audio port
- 1 x Gigabit Ethernet port
Lenovo connected this eGPU dock to one of its new VR headsets. It was running full speed in order for the headset to work. The enclosure felt warm to the touch and the cooling fan was audible through the rear exhaust vents. Lenovo didn’t specify the length of the included Thunderbolt 3 cable. What I saw on display was a .5m Thunderbolt 3 cable.
MSRP is $399, and it should be available at the end of January. According to the User Guide for this Lenovo Graphics Dock, it’s been in testing since July 2017. The decision by one of the world’s largest PC OEMs to release this product at the beginning of 2018 is a clear sign it’s prime time for external graphics.
