Rockstar has not announced a PC version of Grand Theft Auto VI, and no system requirements, including RAM or VRAM, have been published. The game launches on PlayStation 5 and Xbox Series X|S on November 19, 2026. Those consoles have fixed memory, so players do not need to add or upgrade anything.
Community estimates, such as a 150 GB install size or specific RAM figures, are not confirmed by Rockstar or Take-Two. No performance targets, resolution details, or hardware benchmarks have been shared either. The only official videos are Trailer 1, Trailer 2, and An Extended Look, none of which mention PC specifications. A PC port has not been dated, and no 2027 window was ever given.
If you are planning to buy a PC for the game, wait for an official announcement. Rockstar has not said whether a PC version will ever exist, so any purchase based on rumored requirements is a gamble. Follow the PC version page for updates, and check the system requirements section only after Rockstar confirms the port.
