It’s good to finally read something about Sony’s next-generation console. For a while now we’ve been hearing reports or rumors for Microsoft’s new device. This proved to be a good change.
A user on NeoGAF has spotted a recent patent filed by Sony for “Dynamic Context Switching Between Architecturally Distinct GPUs.”
The general abstract of the patent reads:


Graphics processing in a computer graphics apparatus having architecturally dissimilar first and second graphics processing units (GPU) is disclosed. Graphics input is produced in a format having an architecture-neutral display list. One or more instructions in the architecture neutral display list are translated into GPU instructions in an architecture specific format for an active GPU of the first and second GPU.

Sony’s new patent suggests that the PS4 will have two distinct GPUs which will work in harmony, allowing the system to balance the load while processing games with powerful graphical content.
In simpler words, the technology will switch between each GPU when demanded. In practice it would switch to let’s say the first GPU for low-power consumption, that is for normal content; but will tag in the more powerful dedicated GPU for demanding content.



In my opinion this is pretty interesting.
