I think that Sony/MS will go with one chip with multiple cores(integrated CPU and GPU and in near future CPU,GPU and HDD-that thing exist now with 1TB HDD).Something like Larebo maybe but a little diferent.Major plus is MUCH fuster data transmission and lower power consumption.I can see PS4 with integrated CPU and GPU in one chip with,let's say 60 cores.This will gonna happen.It's only a matter of time.

Haven't they already done that? They've basically spent the money and proven that you can get excellent (for a console) graphics performance with a relatively weak GPU. Devs are now familiar enough with t3h C3ll that it's not going to be a barrier to game development for PS4 to keep going along the same path, and given the main development work has been done it's not going to be billions in R&D to beef up the horsepower enough to rid themselves entirely of 3rd party GPUs. PS4 could figuritively be 2 PS3s duct taped together, only with the GPU removed couldn't it? I bet Sony could beef up the Cell (is 2 x Cell1.5 a possibility?) into a console cheaper than what MS would have to pay for a current gen CPU/GPU combination.

With 360 having a superior GPU but developers struggling to match PS3 graphics, and unable to surpass PS3 graphics (at present), Sony is basically showing the world that GPUs can be a thing of the past, therefore why would Sony turn around and pursue a dual GPU route in any way shape or form?

Perhaps Sony has a bigger picture in mind with diminishing the importance of GPUs, or eventually making them entirely irrelevant, in its console. If you can eliminate as much reliance on 3rd party hardware as possible then it means the profits are going to you, not them. Or rather your losses are diminished.

My personal guess is Llano, AMD's 32nm CPU+GPU+Northbridge chip due 2011.

In theory a second gpu can actually give a boost of over 100%. If the load is divided right, it could take away certain ristrictions or bottlenecks that you have when trying to have one gpu do a lot of things at the same time.

The thing is no PC game can be fully optimized for multi gpu systems, since most PC's don't have such a setup. But if a console would use it they could fully optimize the games for it.

Also it could actually be a cheaper solution, since you could use gpu's that are just a bit lower in power but have proven fabrication processes and much higher yields. This opposed to trying to get the maximum out of a (unkown) chip.

Also with every die shrink you save twice as much since you're using two chips(and two slower chips would use a smaller die anyway).

As pointed out already. Cell Is dead.

Sony sold Cell completely to IBM. The whole rights. IBM decided t stop production of Cell in full. No more R&D.

Why? Again as pointed out in this thread. GPU's on PC eat Cell alive. They now have GPU's doing Multiprocesses of what Cell was supposed to be designed for much much more efficently. And CPU manufactorers have CPU's doing the rest of the tasks much much better than Cell can do those.

The future is clearly GPU's being made more into CPU's and helping with those tasks.

If PS4 is to have a Cell, Sony need to front up alot of money to do R&D without IBM funding at all this time to make Cell advancements. Yet it's pointless, considering GPU multi processing is clearly the way forward.

actually, i thought i saw an article about GT5 prologue where you could do that and get a 1440p resolution.

If the cost benefit is positive and worth it then it will happen. Imo, it is a great idea would allow for a very long timeframe between releases and from a purely biz standpoint you want to avoid that if you can.

Sometimes it helps when you read the whole thread... I did see that and i mentioned it in 2 different posts. That was something a little different than GPU scalling though.

That involved 4 PS3s rendering a different quarter of the screen at 1080p each...and compining the image in to 1 giant screen.  And I'd love to see this tech available for purchase as well...lol

Then the developpers would get an inferior looking game to 90% of the people playing it. I doubt more than 10% of the console users would buy 2 systems and 2 copies of the game for some visual benefits...
