Razer announced the Core, one of the first of the new generation of external video card solutions. This enclosure fits compatible double-wide AMD and NVIDIA graphics cards with a maximum length of 310mm and connects to a supporting laptop (like the Razer Blade) or mini PC via Thunderbolt 3.
The Core enclosure measures 104.9mm x 339.9mm x 218.4mm (W x D x H) and features a 500W power supply that can deliver up to 375W to the video card. Furthermore, you also get four USB 3.0 ports, a Gigabit Ethernet port, and two Razer Chroma light zones.
You can pre-order it now via Razer's website, shipments are scheduled to arrive on April 15.
The big problem here is the high price tag, the enclosure costs $499.99 (with a $100 discount if you buy a Razer Blade Stealth) and you still need to provide your own video card. At this price level, the whole external graphics thing still doesn't make a lot of sense.
