The guys over at Digital Foundry and ArsTechnica found that the PlayStation 4 OS consumes 3.5GB of the 8GB GDDR5 of the PlayStation, leaving only 4.5GB for the game, and GPU memory. This is compared to the PS3 where it's OS only consumed 96MB of it's 512MB. And the XBox One had as a limit of staying at or under the 3GB mark, which is what it consumes based on reports.
It is interesting to see what is so special in the PS4 to make it consume so much RAM. In comparison, Windows 8 only need 1GB to operate full featured.
What do you think about all this? Also, what do you think about what the PS4 will be doing on the back to consume so much memory?
