Since then, a handful of manufacturers have brought Thunderbolt 3 functionality to their units, including, notably, Razer back in March. > Alongside the release of new MacBook Pros, the company has taken an extra step toward embracing the tech by giving its seal of approval to a new system from Blackmagic —  the simply named Blackmagic eGPU. The company does these kinds of partnerships from time to time — the LG UltraFine 5K Display being perhaps the most notable example.
