There was a time when the idea of an external GPU was just a dream, something we wanted to see happen but never thought it would.  But several years ago it started to become a reality and that reality continues with the latest launch from Razer with their Core X Chroma eGPU.  There  is  more to  the upgrade over the previous Razer Core X than just RGB for those who thought this was just a lighting upgrade.

From first glace it’s easy to think that the only upgrade that happened was  the  addition of  RGB  to  the  front  and  side,  which  does  feature  a really  nice  Chroma  effect. Internals haven’t changed much in the GPU support area and still support up to a 3 slot GPU making room for some of the beefiest graphics card you can strap to your laptop via the the Thunderbolt 3 port. Thanks to the versatility of the Thunderbolt 3 port it will work with Windows based PCs running the latest Windows RS5 update along with macOS users who are sporting a Thunderbolt 3 port as well as running High Sierra 10.12.4 or later with compatible AMD Radeon cards.
