PS4 gives devs 4.5Gb of useable memory

People have been deriding Microsoft’s Xbox One because it used a whopping 3Gb of its system memory for its triumvirate operating systems, whereas the PlayStation 4 would only use 1gb, giving developers 7Gbs of memory, over the Xbox One’s 5Gb. Only it appears that’s not true, at all.

So says Eurogamer’s Digital Foundry and their ninja sources, right now the P4 only gives developers 4.5Gb of useable RAM.

According to their documentation, 4.5gb of RAM is “the baseline amount of guaranteed memory available for game-makers and most likely what the lion’s share of launch titles will be using.” On top of that , games can request 1Gb of “flexible” memory – essentially a virtual memory swapfile  – if necessary.

“Flexible Memory”,  says Sony 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% 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.”

While that 5 or so Gigs of memory is still ten times what’s available in the current generation consoles, it’s a far cry from what you’d find on even a mid-range PC right now. These “next generation” consoles are looking less future-proof every day.

It does, however, mean that the operating systems for both the Xbox One and PlayStation4 should run like butter, and have proper multi-tasking functionality

Editor. I'm old, grumpy and more than just a little cynical. One day, I found myself in possession of a NES, and a copy of Super Mario Bros 3. It was that game that made me realise that games were more than just toys to idly while away time - they were capable of being masterpieces. I'm here now, looking for more of those masterpieces.
