While the new system retains the same 16GB of GDDR6 memory as the standard model (albeit with more bandwidth), Sony has clawed back an extra 1.2GB of system RAM for game makers. The 12.5GB of available memory for the creators of PS5 games rises to 13.7GB for PS5 Pro. Quite how the platform holder has achieved this is unknown right now. PS4 Pro gave an additional 512MB of RAM to developers and did so by moving low performance systems apps to a secondary pool of new memory, so a similar solution may be in play in PS5 Pro.
