New PS5 Pro details explain what "advanced ray tracing" really means
A new technical seminar featuring PlayStation 5 Pro lead console architect Mark Cerny has been posted to the official PlayStation YouTube channel. It provides some interesting new insights into the hardware that powers the PS5 Pro, including an explanation of what “advanced ray tracing” actually means.
The video is quite technical and begins with Cerny outlining what Sony is hoping to achieve with the PS5 Pro. He says that each new generation of consoles targets “broad improvements” and “significant new capabilities” that allow for a “tremendous step up in what the player experiences”. Mid-generation refreshes like the PS5 Pro, in contrast, are much more “tightly focused” and generally hone in on a few key areas like the GPU.
When developing the PS5 Pro, Cerny states that the focus was to create minimal extra work for developers while still offering games that play “noticeably better”.
Cerny also details some of the technical improvements in the PS5 Pro. While not entirely new information, it does provide a useful recap.
He explains that the 16GB of GGDR6 RAM found in the console is 28% faster than PS5, with over 1GB more memory available to games in order to help with PSSR, ray tracing, and increased rendering resolution. The PS5 Pro also features 2GB of slower DDR5 RAM for the operating system.
He goes on to address some common misconceptions, specifically regarding the power of the PS5 Pro’s GPU. He states that the GPU runs at 16.7 TFLOPs, debunking an earlier myth that it actually ran at a massive 33.5 TFLOPs. He reaffirms the claim that, overall, developers can expect to achieve a 45% increase in rendering speed which he calls “a huge improvement.”
We also get some insight into what the PS5 Pro’s advanced ray tracing entails in technical terms. He states that one of the “top priorities” of PS5 Pro development was “finding ways to accelerate” the computation of ray tracing. This was achieved through a combination of GPU improvements combined and new RDNA features in
