Razer doesn’t scrimp on the internal specs of its premium Razer Blade gaming laptops – but it still likes to keep them slick and thin rather than some of its rivals’ humongous fan-sporting competition. Extra space affords extra power, however, which is why Razer is introducing the Razer Core X, a plug-and-play external graphics card enclosure to boost the gaming potential of its laptop range.

The Core X joins the existing Razer Core V2 in the company’s external GPU case range, but can be considered a stripped-down, bare-bones version focusing on graphics performance rather than the bells and whistles of the Core V2.
