My reaction as well. There's a 80% probability it'll be 16GB. 20 usable for games? Lawl... It'll be 8 for games 8 for OS/Console functionality. This is just speculation on my part, but I'm betting that Sony will be emphasizing alot of 4k OS functionality for the PS5 where the 8GB will be necessary. I think they'll have BIG plans for the PS5's OS and new kick ass features. |
No way the OS uses 8GBytes. The streaming buffer currently uses a good chunk of the os, hence the large reserves in the PS4/X1. They crammed the PS3/X360 os into a few megabytes, and that is the target for any console, make the os as small as possible.
Given that the SoC will be large no matter what (for a 7nm design), I think there is room for a 320 or even a 384bit gddr6 interface (20 or 24Gbyte ram). I highly doubt there will be two different memory bus architectures in the SoC, it's just too big a mess to design and synchronise (the cpus already have the synchrinise penalty built in so you would avoid any additional penalty as much as you can). Maybe even only a 256bit gddr6 interface and some cheap 4-8GByte streaming buffer somewhere downstreams (getting rid of the memory reserves we have now) would be enough for a PS5.
