Researchers from North Carolina State University have developed a new technique that allows graphics processing units (GPUs) and central processing units (CPUs) on a single chip to collaborate – boosting processor performance by an average of more than 20 percent.

“Chip manufacturers are now creating processors that have a ‘fused architecture,’ meaning that they include CPUs and GPUs on a single chip,” says Dr. Huiyang Zhou, an associate professor of electrical and computer engineering who co-authored a paper on the research. “This approach decreases manufacturing costs and makes computers more energy efficient. However, the CPU cores and GPU cores still work almost exclusively on separate functions. They rarely collaborate to execute any given program, so they aren’t as efficient as they could be. That’s the issue we’re trying to resolve.”

Saw this coming/predicted it even before APUs came out. When NV showcased using GPUs for CPU tasks years ago...it was like just one massive hint of where future tech was going. But can AMD capitalize it? Curious to see. Intel can utilize the same idea but their GPU tech is so far behind that I could see them leveraging the CPU side even more to compensate. So then it is a matter of how far AMD can take it to offset their weakness on the x86.

Either way, forces both companies to innovate. Innovation is good!!

Ha! Wait a second! Didn't they say -and we believe...- that we are having this feature since we installed our first Physix enabled videocard? hohoho! HOHOHOHO!

+1:) but arm and nvidia imho make this more then a two horse race from here on so i am likeing AMD's open standards policy regarding HSA as hopefully most Inovators will at least try and get them standards working across platforms ,but ive a fiver says nvidia make up some more stuff only they can use.

This stuff would probably remain as an abstract unless AMD took the aggressive stance.

hopefully , I prefer open standards that everybody works to, that way the devs have to work harder to make their chip better than others rather then trying to differentiate with under used additional features that need to be tailored for specificaly

and just when you start to think your pc might last a while an all, tutt be next year im looking at mine with that hmmmm upgrade time eye:)

this looks very good for amd in the coming years.

Keep in mind, they didn't actually physically accomplish anything yet. With the help of AMD Engineers they modeled how a supposed performance gain could potentially occur, but have yet to get it functioning. When APU's were first introduced I figured they would find a way to have the GPU and CPU simultaneously process when a Discrete GPU Solution was present, but apparently they didn't care much for developing that idea. This entire study should be taken with a truckload of grains of salt.

well they can't use it now since there is no software support for something like this. but in 5-10 years... intel has nothing like this and i bet heterogenous computing is going to gain some serious ground in the near future simply because amd made a chip that that makes it commercially viable.

What happens if the GPU is busy doing video-related work and the CPU throws a calculation request at it? Does the display stutter or freeze? Or does the GPU perform the calculations more slowly? In that case, the CPU might be able to perform the calculations faster just because it isn't bogged down with other work. Definitely an issue to take into consideration.
