The internal codename for the PlayStation 4 was Orbis.
Sony developed the console under the name Orbis before publicly revealing it as the PlayStation 4 in February 2013. The codename appeared in early reports about the system and was also associated with developer-facing software and technical documentation. “Orbis” is Latin for “world” or “circle,” fitting Sony’s broader naming style for PlayStation hardware and services.
The PS4 launched in November 2013 with an x86-64 AMD processor, an AMD Radeon-based graphics processor, 8 GB of GDDR5 memory, and a strong emphasis on social features and digital distribution. Its predecessor, the PlayStation 3, had used the distinctive Cell processor architecture, so the PS4 represented a major technical shift toward hardware more familiar to PC developers.
A common mix-up is Oberon, which is associated with the PS4’s GPU design, and Liverpool, a development codename connected with Sony hardware projects. Neither was the console’s main internal codename. Neo was later used for the upgraded PlayStation 4 Pro project.
