Rumour: 5GB will be available to developers for PS4 games
Joe Anderson | 3 years ago
Sony has issued a statement to Eurogamer clarifying how memory works on PS4.
This comes after the same site posted an article claiming that developers would only have 3.5GB of RAM free for games, with another 1GB of RAM freeing up if the system allowed.
Here's the statement in full for those tech heads out there that actually care:
We would like to clear up a misunderstanding regarding our "direct" and "flexible" memory systems. The article states that "flexible" memory is borrowed from the OS, and must be returned when requested - that's not actually the case.
The actual true distinction is that:
"Direct Memory" is memory allocated under the traditional video game model, so the game controls all aspects of its allocation.
"Flexible Memory" is memory managed by the PS4 OS on the game's behalf, and allows games to use some very nice FreeBSD virtual memory functionality. However this memory is 100 per cent the game's memory, and is never used by the OS, and as it is the game's memory it should be easy for every developer to use it.
We have no comment to make on the amount of memory reserved by the system or what it is used for.
According to Eurogamer, what this means is that 4.5GB of conventional RAM will be available to developers, while another 512MB of on-chip RAM is also free if necessary. In other words, of the 8GB of GDDR5 on PS4, 5GB is available to developers and not 3.5 as previously stated.
