Forums - Sony Discussion - PS4 Rumour: Sony Files Patent For Dynamic Content Switching Between Architecturally Distinct GPUs

According to the guys of Neogaf. The weaker GPU will be used for other functionalities , while a more powerful one will be used for games.

Power efficiency seems to be a main concern for Sony.

Interesting... but I think it would make development for a PS4 very complicated as its nothing like a normal dual GPU set-up or what he APUs are even initially designed for.

Haven't we gone through this at least a hundred times (in your other thread).

The AMD A10 (rumoured in the PS4) has a non-gcn GPU. So in order to pseudo-crossfire it, you need another  non-gcn separate GPU.

If they want to reach the promised 1080P 60Hz, the GPU in the A10 just won't get there so they need a separate (another word for separate it is distinct) GPU. If they add a more modern GPU to the PS4 to reach that goal (a.k. gcn architecture), they end up with content switching between two distinct gpus....

Oh my, I just wrote what the patent says... what an absolutely unexpected amazing surprise........ not

My laptop Has an A10 and it run Diablo 3 with everything up at 120 frames a second. So i don't quite understand why you say it cant do 1080 at 60

I don't understand your condescending tone in that post.

I recognize the rumor and patent... just stating that I think it will make it more complicated than staying with what the APUs are intended for.

APU will replace the CPU. it sits on the same chip as the GPU here are no bottle necks with a APU set up.
that would be cool if the PS4 used 2 gpus


so there's no CPU. i'm tech ok. closer to stupid, but ok.



Looked it up and it's a real patent issued by Sony

That basically confirms dual APU and GPU in next Playstation. Why else would they bother patenting something like that

There have been rumours mentioning an APU + seperate GPU for quite some time. This strengthens those rumours.



Since no one want to actually provide a link to the actual patent.

You're welcome....

I am the Playstation Avenger.

   

why would it make things more complicated? Doesn't the patent say that it uses a neutral interpretive language to allow them to speak to one another?
shouldn't that just mran that you do your programming and the translator decides what to do with it? Don't really understand how that makes it more difficult. to me it sounds like a cell except a cell that can interpret regular coding into optimized coding, imo.

"BACKGROUND OF INVENTION 

[0003] Many computing devices utilize high-performance graphics processors to present high quality graphics. High performance graphics processors consume a great deal of power (electricity), and subsequently generate a great deal of heat. In portable computing devices, the designers of such devices must trade off market demands for graphics performance with the power consumption capabilities of the device (performance vs. battery life). Some laptop computers are beginning to solve this problem by introducing two GPUs in one laptop--one a low-performance, low-power consumption GPU and the other a high-performance, high-power consumption GPU--and letting the user decide which GPU to use. "

They should at least mention where the info came out from.

Anyways great stuff :)
