Razer's 'Core' external GPU ships in April for $500

The "Best of CES" winner works with both of the new Blade laptops.

Razer announced pricing and availability for its new Core external graphics box at GDC on Wednesday. The device is available for pre-order starting today and units will begin shipping in April. It will set you back $400 if purchased in tandem with a Blade Stealth or $500 if you buy it separately. But don't worry if you didn't take our advice and have already purchased a Blade Stealth, you'll still get the $100 discount.

The Core operates through a single Thunderbolt 3 (USB-C) plug to deliver both power and data (up to 40 Gbps) to the connected ultrabook. Plus, It supports double-wide, full-length, PCI-Express x16 card from AMD or NVIDIA -- that's four times the data bandwidth of what its rival, the Alienware Amplifier, offers. What's more, the Core will include four USB 3.0 ports and wired Ethernet connectivity. Note, you will need to buy a graphics card separately to stick into the Core. The following models will be compatible at launch:

Qualified AMD Radeon graphics cards:
- R9 Fury
- R9 Nano
- R9 300 Series
- R9 290X
