While external graphics has been a thing for quite some time, it was rarely an available thing. Several companies, such as AMD, Lucid, and others, announced products that were never sold. ASUS had their XG Station for Windows Vista that allowed laptops to plug into a GeForce 8600 GT, which was only available in Australia. Only now are we beginning to see options from Alienware, MSI, and even Microsoft that are widely available.
ASUS is jumping back in, too. Not much is known about the XG Station 2, except that it is “specially designed for ASUS laptops and graphics cards.” This sounds like it is using a proprietary connector, similar to Alienware and MSI, to connect to ASUS laptops. Also saying it's specifically for ASUS graphics cards is a bit confusing, though. If it is an open PCIe slot, I'm not sure why or how it would be limited to ASUS cards. If the graphics cards are pre-installed, then we don't know the list of potential GPUs.
Either way, ASUS states that the dock can be disconnected without shutting down the PC. I'm interested to see how the GPU is supposed to be unplugged, as Alienware's option can only be done when the system is off, and Microsoft's Surface Book has a software detach with a hardware latch. The connector will also charge the laptop, which is an interesting add-in.
Pricing and availability varies, like the other ASUS announcements, by region.
