If you’re curious as to how PlayStation 4 Pro can produce better graphics, present additional options and nonetheless play present video games within the course of, Mark Cerny has the reply.
Speaking at convention at Sony’s San Mateo HQ attended by Digital Foundry and different retailers, PlayStation architect Cerny defined that to be able to obtain this, the has been doubled.
The console will sport two chips and the system makes use of one to play present tiles, after which when a Pro recreation is popped in, each chips work in tangent.
“We doubled the GPU size by essentially placing it next to a mirrored version of itself, sort of like the wings of a butterfly,” he defined.
“That gives us an extremely clean way to support the existing 700 titles. We just turn off half the GPU and run it at something quite close to the original GPU.”
Cerny mentioned he and his crew additionally felt video games wanted “about 10% more memory,” which is why they added a gigabyte of gradual, typical DRAM to the console making it “DDR3 in nature.”
“On a PS4 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,” he mentioned. “Nothing must be loaded, it’s already in reminiscence.
“On PS4 Pro, we do issues in another way, once you cease utilizing Netflix, we transfer it to the gradual, typical gigabyte of DRAM. Using that technique frees up nearly one gigabyte of the eight gigabytes of GDDR5. We use 512MB of that freed up house for video games, which is to say that video games can use 5.5GB as an alternative of the 5 and we use a lot of the relaxation to make the PS4 Pro interface – which means what you see once you hit the PS button – at 4K relatively than the 1080p it’s in the present day.”
During the assembly, Cerny reiterated PS4 Pro isn’t the start of a new generation, per Gamasutra.
“We don’t believe that generations are going away,” he mentioned. “They are truly healthy for the industry, and for the gaming community. It’s just that the objectives for PS4 Pro are quite different.”
