In May 2019, Nvidia announced new RTX Studio laptops. The creators say that the new laptop is going to be seven times faster than a top-end MacBook Pro with a Core i9 and AMD's Radeon Pro Vega 20 graphics in apps like Maya and RedCine-X Pro. In August 2019, Nvidia announced Minecraft RTX, an official Nvidia-developed patch for the game Minecraft adding real-time DXR ray tracing exclusively to the Windows 10 version of the game. The whole game is, in Nvidia's words, "refit" with path tracing, which dramatically affects the way light, reflections, and shadows work inside the engine.

In October 2020, Nvidia announced its plan to build the most powerful computer in Cambridge, England. Named Cambridge-1, the computer will employ AI to support healthcare research, with an expected completion by the end of 2020, at a cost of approximately £40 million. According to Jensen Huang, "The Cambridge-1 supercomputer will serve as a hub of innovation for the UK, and further the groundbreaking work being done by the nation’s researchers in critical healthcare and drug discovery." Also in October 2020, along with the release of Nvidia RTX A6000, Nvidia announced it is retiring its workstation GPU brand Quadro, shifting product name to Nvidia RTX for future products and the manufacturing to be Nvidia Ampere architecture based. In August 2021, the proposed takeover of Arm Holdings was stalled after the UK's Competition and Markets Authority raised "significant competition concerns". In October 2021, the European
