It's going to be 10 24 Gb modules, apparently, given Kepler said about bus width, so OS memory not included. GDDRR7 was estimated to cost $3-4 per GB earlier last year, so a doubling or tripling in price could add $100-$200 to the final price of a 30GB console... if it were to release during the memory crunch, that is. |
This.
They are using 3GB (24gbit) memory chips instead of 4GB (32gbit). {8 bits in a byte}
It will mean it will likely have a 320bit memory bus for over a Terabyte (Maybe 1.2Tb/s?) of memory bandwidth.
4-8GB of Ram for OS/Background tasks will likely be the standard, it really depends how much they wish to upgrade the OS, the jump from the PS4 to PS5 wasn't a big OS leap, but the OS could use faster SSD storage for a swap file more effectively.
They would have done this as a cost/benefit analysis where there is a preference for speed over sheer capacity.
Handhelds today already have 24GB-32GB of Ram... And PC's have transitioned to 32GB System memory for the optimal capacity for a number of years now.
