This is the original Razer Core, not the Core X or Chroma. It is essentially an EGPU with dock capability as well - it is Thunderbolt 3 but is also compatible with most devices that have USB 4.0 (tested and verified myself).

Please Note This enclosure only fits 2 slot cards - a 3080 founders edition works great for example. It is your responsibility to check if your card will fit before ordering.
