Mark Cerny talks about how the developers influenced the design of PS5

We all remember that technical presentation, focused on video game developers, that Mark Cerny made of the hardware that will have PlayStation 5 in March 2020 when we had not yet seen the console. The technological medium Wired has published a video where the PS5 architect summarizes the content of that conference, explaining it to a less specialized audience. In his speech he says nothing that was not already known, except for how video game designers influenced design of the latest generation machine.

Cerny remembers his career as a video game developer: for 40 years he has worked on titles such as Marble Madness, Crash Bandicoot and Knack. “Bringing the game developer community into the hardware development process is something that is quite recent, hysterically speaking. Over the years that was a dialogue that personally, as a developer, I’ve always wanted to have“.

“I’m looking for the developers who give me difficult moments, those who have really strong opinions about what they need to make the game they dream of, “confesses the architect.” brutal meetings, but good to have, because at the end of the day, you’re making a more robust console. “

Throughout the video of about 15 minutes he lists the console functionalities and why they chose a processor with eight cores (despite the fact that some developers requested up to 16 cores), why the technology for which they opted for the NVMe SSD was chosen and other details, but the explanation of I / O technology.

Cerny explains why some PS5 games are smaller than PS4 games

During the last months, in the comments of this website, in social networks and in other forums, many players have wondered Why are there PS5 games that take up less than PS4 games even though they have higher resolution textures or higher quality effects. “We are committed to a strategy that we call ‘integrated IO'”Cerny starts up. “The main function of integrated IO from a developer point of view is the invisible compression“.

“Developers have to spend a lot of time and effort loading data and extracting it from storage, be it a hard drive or an SSD. With integrated IO, we take care of all of that. The developers carry your data to our publishing tools. So while the game is running, it just asks for the data and we will take care of the decompression for it. “

Cerny continues: “We put as much functionality as we could into a custom unit on our main chip. The impact of this compression strategy is enormous. Matching rod to match, but some highlights are Subnautica, which occupies 14 gigabytes on PS4 and only four gigabytes on PS5; Control: Ultimate Edition, what occupies 50 gigabytes on PlayStation 4 and about half and PS5 “.

PlayStation 5 went on sale on November 12, 2020 (In Spain we had to wait another week, until November 19). Since then, as has happened with Xbox Series X and other technological gadgets, buying one of these machines has been complicated by the lack of supply, a situation that, according to chipmakers and Sony’s own internal reports, will not be solved anytime soon.
