At CES, Razer has unveiled an ultrabook-class laptop that can connect to an external graphics card via Thunderbolt 3, using a nifty external graphics enclosure called Core.
The Razer Blade Stealth arrives in a petite aluminum package weighing 2.75 lbs and measuring half an inch thick. The 12.5" IPS touchscreen comes in 2560 x 1440 or 3840 x 2160 flavors. All Stealth notebooks get PCI Express SSDs, and they'll all ship with an Intel i7-6500U processor and a non-upgradable 8 GB of RAM. This machine doesn't come with discrete graphics, though. That's where the external Core enclosure comes in.
The Core uses Thunderbolt 3 to communicate with the Blade Stealth. This enclosure includes an internal 500W PSU in order to accommodate a dual-slot PCI Express graphics card—not included, of course—with up to 375W of power draw, or "virtually every popular desktop graphics card from AMD and Nvidia," according to Razer. The Core also sports four USB 3.0 ports and an Ethernet port, and it can power the laptop over the Thunderbolt 3 connection.
The Razer Blade Stealth will be available for purchase from Razer and the Microsoft Store in February this year. $999 gets buyers the version with a 1440p screen and a 128GB SSD. $1,599 buys the upgrades to the 2160p screen and a 512GB SSD. We're not sure how much the separate Core enclosure will cost or exactly when it will be available, but Razer assures us it will ship within the first half of 2016.
