We’re still waiting for AMD to introduce Vega 7-nanometer (nm) graphics cards, but AMD has may have just jumped the gun and named its next-next generation GPU architecture.

An AMD Linux driver development employee name-dropped Arcturus as a possible code name for the company’s previously unnamed 7nm+ GPU architecture, slated for a 2020 announcement. The comment was made on the Phoronix forums, explaining that AMD is supposedly planning to return to distinct code names for each of its GPU architectures.
