Razer is updating its Core line of external GPU enclosures today, introducing a new Core X model and adding support for Apple’s MacBook Pro laptops with Thunderbolt 3 ports.

The Core X is designed as a new, entry level model for Razer’s external GPU line, costing just $299 (as opposed to the Core V2’s $499 price tag), although it loses out on some of the Core V2's more advanced features like USB and Ethernet ports and Razer’s Chroma lighting. That said, the Core X does offer some improvements over the Core V2, with 100W pass-through charging over Thunderbolt, an integrated 650W power supply (versus the V2’s 500W), and support for larger 3-slot GPUs (compared to the 2.2-GPU size on the V2.)
