The Razer Blade Stealth isn't a gaming laptop -- until you plug it into the Razer Core, a docking station that not only adds ports and charges the laptop, but also adds the horsepower of an external graphics card.
You get to choose which graphics card to add. Just flip open the handle, pull and the tray slides right out. One screw, two power connectors and you're done.
Just plug a single USB Type-C Thunderbolt 3 cable into to the side of the laptop -- no need to reboot -- and all that additional graphical oomph is yours.
You don't have to rely on just that single USB-C port, though. There's also a full-side HDMI jack and two full-size USB 3.0 ports on the Blade Stealth laptop.
Here's what a full Blade Stealth plus Core desktop setup might look like -- if you're a big fan of Razer products, anyhow.
