Sony recently launched a newer, slimmer model of PlayStation 4, and another model is set to release on November 10th. PlayStation 4 Pro gives consumers a more powerful (and more expensive) option that offers improved visuals and enhancements like HDR and 4K. Following the initial announcement, Sony has revealed one more way in which PlayStation 4 Pro is superior to the standard model: it has more RAM.
The current PlayStation 4 models have 8 GB of GDDR5 RAM, but Pro has a little extra. An additional 1 GB of “slow, conventional DRAM” has been added to the upcoming console. When switching between an application and a game, that application remains resonant in the system memory so that you can switch between the two quickly. On PlayStation 4 Pro, those background applications will be moved to the extra 1 GB of RAM. According to PlayStation 4 architect Mark Cerny, this will also free up 512 MB of RAM for games, giving developers around 5.5 GB to work with for games while the rest is used for the console’s interface.
