How much RAM does the PlayStation 5 have?

The PlayStation 5 has 16 GB of RAM. More precisely, its main memory is 16 GB of GDDR6 SDRAM shared by the console’s CPU and GPU through a unified memory system.

That memory runs across a 256-bit interface and provides a peak bandwidth of 448 GB/s. Compared with the PlayStation 4’s 8 GB of GDDR5, the PS5 doubles the headline memory capacity while also using a newer, faster memory standard. This helps the console handle higher-resolution assets, larger game worlds, and advanced visual effects.

The 16 GB figure applies to the standard PlayStation 5 and its Digital Edition, which use the same core memory specification. It should not be confused with storage: the original PS5 shipped with an 825 GB custom SSD, while later Slim models commonly include 1 TB of storage.

The PS5 Pro has a more complicated memory layout and includes additional system memory, but its primary GDDR6 pool is still 16 GB. For the regular PS5 discussed in this question, 16 GB is the standard and canonical answer. Some of that unified memory is reserved for system software, so games cannot use the entire amount.
