|8 Cores / 16 Threads|
|Variable frequency, up to 3.5 GHz|
|GPU||AMD Radeon™ RDNA 2-based graphics engine|
|Ray Tracing Acceleration|
|Variable frequency, up to 2.23 GHz (10.3 TFLOPS)|
|System Memory||GDDR6 16GB|
|5.5GB/s Read Bandwidth (Raw)|
|PS5 Game Disc||Ultra HD Blu-ray™, up to 100GB/disc|
|Video Out||Support of 4K 120Hz TVs, 8K TVs, VRR (specified by HDMI ver.2.1)|
|Audio||“Tempest” 3D AudioTech|
The PlayStation Blog includes more detail about Cerny’s over fifty minute discussion, highlighting many of the bigger points:
As Mark discussed in his presentation, PS5’s ultra-high-speed SSD and integrated custom I/O system were developed with the goal of removing barriers to play – specifically loading screens. Developers are able to stream assets into PS5 games at an incredibly fast rate, so PS5 play experiences can be seamless and dynamic, with near-instantaneous fast travel through large game worlds. This enhanced speed will enable game developers to create larger, richer worlds without traditional limitations, such as load times, and also allows gamers to spend more time gaming than waiting.
We also wanted to introduce new capabilities with PS5’s custom GPU. Additional GPU power will allow for higher resolution in games, but a major new feature that benefits the visuals of games even further is ray tracing. Ray tracing simulates the way light moves in real life, and how it bounces off various surfaces. Games that take advantage of this feature will render objects much more accurately, and with heightened realism. Water, glass, light refraction, a character’s hair and so on, will look even more realistic.
PS5 will also allow games to offer a much deeper sense of immersion through 3D audio. Visuals are of course imperative to the gaming experience, but we believe audio plays a crucial role as well. We wanted to deliver a compelling audio experience for all users, not just those who own high-end speaker systems. So we designed and built a custom engine for 3D audio that is equipped with the power and efficiency for ideal audio rendering. With 3D audio on PS5, the sounds you hear while playing will offer a greater sense of presence and locality. You’ll be able to hear raindrops hitting different surfaces all around you, and you can hear and precisely locate where an enemy is lurking behind you.
Lastly, we’re excited to confirm that the backwards compatibility features are working well. We recently took a look at the top 100 PS4 titles as ranked by play time, and we’re expecting almost all of them to be playable at launch on PS5. With more than 4000 games published on PS4, we will continue the testing process and expand backwards compatibility coverage over time.
As of yet, there’s no confirmation on price, release date, or games.
