December 19 (Portaltic/EP) –
PlayStation and AMD have embarked on a new collaboration with which they seek to create a “more ideal” architecture for machine learning that benefits game consoles and democratize access to this technology.
The chief architect of PlayStation 5 and PlayStation 5 Pro, Mark Cerny, has detailed in a technical seminar the new features that boost the graphics in Sony’s new game console, which hit the market at the beginning of November.
These are based on a larger GPU, advanced ray tracing technology and the use of machine learning to scale resolution; elements that have more work behind them and that Sony has shared now, also anticipating what they hope to achieve in the future.
Machine learning or artificial intelligence plays an important role in the new PS5 Pro, because it is the technology that boosts performance and offers more precise graphics and higher resolutions.
To do this, a larger GPU has been implemented by AMD, in which they have used a hybrid rnd architecture, with rdn2 at the base and part of the characteristics of rdn3. It has also been accompanied by a larger memory that supports this new GPU and is faster.
In this case, Sony has opted for GDDR6 RAM, which supports a bandwidth of 576GB/s (compared to 448GB/s for PS5), but has also included slower DDR5 RAM that takes care of a significant part of the work of the operating system, to leave faster RAM for games and technologies such as ray tracing and resolution scaling.
The PS5 Pro GPU has 30 work group processors (WGP), compared to 18 in the PS5 GPU, that is, 67% more, which also increases the flops by 67%, according to Cerny, up to reach 16.7teraflops, maintaining an operating frequency of 2.17GHz.
Together, the GPU increases the rendering speed by 1.45x. As the chief architect has explained, if a 60fps game takes 16 milliseconds to render an image on PS5, it will do so in eleven milliseconds on PS5 Pro.
Added to this is that the speed of advanced ray tracing has doubled or tripled, depending on the use case, thanks to the fact that the GPU has 67% more WGP.
AMETHYST PROJECT
According to Cerny, the company began work on PS5 Pro in 2020, “before PS5 had even been launched”, with the aim of bringing it to the market in 2024. And in order to improve the technologies that will equip video game consoles in the future, has announced a new collaboration with AMD.
This is the ‘Amethyst’ project, and it has two main goals: to create a “more ideal” architecture for machine learning, and to democratize the use of machine learning among game developers.
