How many bits is a PS4?

The PlayStation 4 (PS4) is a 64-bit console.

Explanation:

• The PS4 uses a custom AMD x86-64 architecture based on the Jaguar microprocessor, which is a 64-bit architecture.
• This 64-bit architecture allows the PS4 to handle large amounts of memory, support more complex games, and run modern 3D graphics with much higher efficiency than older 32-bit consoles.

The 64-bit architecture in the PS4 allows it to address a larger memory space (up to 8 GB of GDDR5 RAM) compared to the limitations of earlier 32-bit systems, like the PS3.

Conclusion:

While older consoles like the PS1 and PS2 were 32-bit and 128-bit, the PS4 is based on 64-bit architecture, reflecting the more advanced technology and hardware capabilities of modern gaming systems.
