Speaking during an interview with IGN, PlayStation 4 architect Mark Cerny has revealed that the PS4 Pro specs have been boosted an extra 1GB of RAM.
Cerny explained that as the new system is still part of the current generation of consoles, Sony took a “different direction” in upgrading the hardware. Typically, a console would receive a significant upgrade in RAM when shifting to a new generation of hardware.

"We felt games needed a little more memory, about 10 percent more, so we added about 1GB of slow, conventional DRAM to the console,” he said.
Talking about the PS4 Pro specs, he went on to explain that "games have just a little more memory, 512MB to be exact, and most of that is used for the various buffers needed when rendering high-resolution or higher-quality graphics, and the game assets… stay the same, they just look a heck of a lot better on the new console."
