Sony Explains Benefits Of PS4 Pro’s Additional 1GB Of Memory

by Mike Guarino


While the PlayStation 4 Pro will be more powerful that the standard PlayStation 4, there are instances where the changes are very small. One such instance is with the consoles memory, as it has just 1GB more than what the standard PlayStation 4 offers.

However, Sony has now explained how this will benefit the console and its games, with Mark Cerny saying “We felt games needed a little more memory – about 10 per cent more – so we added a gigabyte of slow, conventional DRAM to the console. On a standard model, if you’re switching between an application, such as Netflix, and a game, Netflix is still in system memory even when you’re playing the game. We use that architecture because it allows for a very quick swap between applications. Nothing needs to be loaded, it’s already in memory.”

He goes on to say “On PS4 Pro, we do things differently, when you stop using Netflix, we move it to the slow, conventional gigabyte of DRAM. Using that strategy frees up almost one gigabyte of the eight gigabytes of GDDR5. We use 512MB of that freed up space for games, which is to say that games can use 5.5GB instead of the five and we use most of the rest to make the PS4 Pro interface – meaning what you see when you hit the PS button – at 4K rather than the 1080p it is today.”

The release of PlayStation 4 Pro isn’t far off now, as the console will launch on November 10th and costs $399. It will be the second variation of the PlayStation 4 that Sony has released this year, with the PlayStation 4 Slim launching last month for $299.
