PS4′s Asynchronous Fine-Grain Compute GPU: What the Heck Can it Do?

Giuseppe Nelva of DualShockers.com explains the technical ins and outs of the future-proofing features named by Mark Cerny for the GPU of the PS4 like Ray casting for Audio, World Simulation, Decompression, Physics Simulation and Collision detection. (Mark Cerny, PS4)

Basically, it allows the GPU to be used for tasks that would normally be handled by the CPU. Whenever the GPU will have unused potential, which is ALWAYS, it will be able to handle computing tasks.

And GPUs are several orders of magnitude more powerful than CPUs, because they are made out of many, many cores that work in parallel.

If you want to see what that means visually, here's a particle system running on the GPU (instead of the CPU particle systems we're currently used to see) : http://www.youtube.com/watc...

here's another example of the power of the gpu

some benefits of this is that it reduces the load on the CPU, meaning it will have more room for tasks only the CPU can perform.

and also puts less load on the RAM because less data will need to travel between the GPU and CPU thru RAM.

this also leads to less burden on the developers, because they don't need to spend much time writing the pipelines/paths for data running between the GPU and CPU.

in short. more multitasking scenarios...

that's about it

I would like to add that GPGPU can be used to tremendously improve AI in games as well.

And don't foget the fact that the PS4's GPU is 50% more powerful than the xbone's.
so gpgpu, direct compute, OpenCL sh!t?

In short; PS4 is gonna be an amazing machine

Potentially, too bad that those features won't come before 2-3 years. Ray tracing for audio is amazing.
Alexious  +   421d ago
Well, it just depends on developers' skills.

Anyway, PS4 is just teeming with potential. One little turnoff is that Cerny's Knack doesn't look too special, even from a technical point of view.

I guess that depends a lot on the whole development team, though.

Nice article.

Ps4 has a modest CPU but custom GPU with 64 compute huge increse from 4 compute that the normal pc verion would have.

Xbox has 2 or 4 i dunno.
Abriael  +   421d ago
I may be wrong but PC is 2 compute, at least for that kind of card.
a08andan  +   421d ago
Xbox One has 12 CU's and the ps4 has 18 if I'm not mistaken. Each CU capable of 64 operations per cycle :)
GDDR6_2014  +   421d ago
ps4 has 18 compute units

so thats between a 7850 (16) and 7870 (20),

AMD's higher end GPUs, 7950 has 28 CUs, 7990 has 64 CUs

They can all do 64 instructions (SIMD) per second

With nvidia making Volta with around 24 tlops in 2016 imagine how much the PS5 will have if its realesed in 2018-19.
edit : ps3 0.240gflops
ps4 1.2Tflops
ps5 24tflops minimum xD

PS4 1,8 i meant
Sevir  +   421d ago
yep, itll be a graphical beast but im sure theyll partner with AMD
We'll just have to see the market in the next 7 or so years, I'm not sure if consoles will be a profitable thing after this generation... But I'm sure as hell gonna have the next console that follows the PS4.

They'll partner with whomever gives them the best deal :D

It can give me a semi even though I don't know what it means!
Destrania  +   421d ago
Simply put, PS4 will be amazing.
Vip3r  +   421d ago
Hows does the PS4's CPU & GPU compare to the average modern PC's CPU and GPU in terms of processing power?
Hicken  +   421d ago
But specs don't mean anything, right, Microsoft? Not only that, but we don't know anything about the specs or what they'll mean, right?
