As well as unveiling their new Lenovo Mirage Solo standalone VR headset and other hardware at CES 2018 this week, Lenovo has also taken the wraps off its new Thunderbolt External Graphics Dock. Equipped with a Nvidia GeForce GTX 1050 graphics card sporting 4GB of GDDR5 MXM memory, to add extra processing power to a laptop, desktop or mini PC. Lenovo claims the external GPU supports WMR at 90Hz and recommends that the Thunderbolt Graphics Dock be used with the IdeaPad 720S Ultrabook at the current time although other systems running Windows might support the external graphic dock in the future.
The Thunderbolt External Graphics Dock is powered by an 170W AC adapter and connects to your PC via a USB Type-C connection and offers up to 65W of power for attached PCs. As explained the only certified device at the current time is the Lenovo IdeaPad 720S and you can expect more devices to be added in the very near future. For example at CES the external graphic dock is also being demonstrated connected to a ThinkPad X1.
Measuring just 5.12 x 9.76 x 0.89 inches in size and weighing roughly 1.5lbs the external graphics dock is much smaller than other competing devices currently available on the market. The Lenovo graphics dock is equipped with Gigabit Ethernet, 2 x USB 3.0 and 1 x USB 2.0 ports and supports the ability to connect up to 3 displays using the HDMI 2.0 port or two DisplayPort 1.3 ports. The Lenovo Thunderbolt 3 Graphics Dock is expected to be made available later this month and will be priced at $399.
