Sony has filed a new patent for a multi-GPU approach for a client & cloud-based console, which to cut out a long bunch of technical chatter, would allow for a PS5 Pro-like system.
New Sony Patent Suggests Possibility Of PS5 Pro Device
The description of the patent can be found below. It’s a lot of technical banter, but essentially, it mentions the possibility of two consoles existing: a light version featuring only one CPU & GPU combo, and another enhanced version that has two or more combos, plus extra RAM and other features.
In a multi-GPU simulation environment, frame buffer management may be implemented by multiple GPUs rendering respective frames of video, or by rendering respective portions of each frame of video. One of the GPUs controls HDMI frame output by virtue of receiving frame information from the other GPU(s) and reading out complete frames through a physically connected HDMI output port. Or, the outputs of the GPUs can be multiplexed together.[/quote]
Simulation consoles such as computer game consoles typically use a single chip, referred to as a “system on a chip” (SoC) that contains a central processing unit (CPU) and a graphics processing unit (GPU). Due to semiconductor scaling challenges and yield issues, multiple small chips can be linked by high-speed coherent busses to form big chips. While such a scaling solution is slightly less optimal in performance compared to building a huge monolithic chip, it is less costly.
As understood herein. SoC technology can be applied to video simulation consoles such as game consoles, and in particular a single SoC may be provided for a “light” version of the console while plural SoCs may be used to provide a “high-end” version of the console with greater processing and storage capability than the “light” version. The “high end” system can also contain more memory such as random-access memory (RAM) and other features and may also be used for a cloud-optimized version using the same game console chip with more performance.
Sony hasn’t announced any plans for a PS5 Pro device, although there are two versions of the console due – a Digital-Only Edition and the standard model.
