Report: PlayStation 4 Rumored to Use AMD Fusion CPU/GPU
Given the transitional state of console gaming, the success of the Xbox 360/Kinect, and Nintendo's experiments with a new controller type, Sony will need something big for the PS4.
The core building block appears to be AMD hardware.
Information about the inner workings of the next PlayStation have been trickling out for some time, with no way to determine how accurate those bits and pieces are. Nevertheless, the reports are interesting and could point to a trend on how console makers are planning to keep today's consoles relevant in their own game as well as in a trend that is leverages general purpose applications that merges active entertainment (gaming, social engagement) with passive entertainment (audio, video, TV). The PlayStation-centric site PSX Sense reports that Sony may be building they next console, code-named Orbis, mainly on AMD hardware.
There will be a Fusion processor codenamed Liverpool. The APU may have four cores and run at 3.2 GHz. the site also lists a "Tahiti" R10XX GPU that is capable of 1,843 Gflops at 800 MHz clock speed, 2 or 4 GB memory, a Blu-ray drive, HDMI 1.4 support, 16 GB Flash memory and at least 320 GB HDD space. The launch date is sometime in 2013.

And everybody will be laughing at you for spending so much to play console ports
Well if Sony expects availability from Nvidia, that is way more of a gamble.
Hasnt been a problem so far, considering they are in several consoles. But then again, they will probably just sell the customized ip off wholesale, like they did with microsoft for the 360.
this being almost 2tflop... its not top of the line, but is far better than most computers have today, i could imagine that if epic gets there way, you may see the gpu side reworked yo push it to 3tflop.
but not only that, but if sony isnt pushing the billions into a custom gpu/cpu combo, than this may become the gold standard that pcs get held to with you have this much power, or possibly that they preform better on an apu than a slightly more power cpu and gpu combo.
i am likeing this.
i have a 5770, that is far less powerful than what is proposed, but i have yet to play a game that cant play with great detail at 1080p, granted i turn down shadow detail in every game regardless of how well it plays just to push the fps a bit higher.
I highly doubt it, consoles use overclocked versions of gpus, and a base clock for a 7850 is a 860mhz clock speed. since this one is 800 mhz, it has the same memory bandwidth as a 7750. a 7750 has 819.2 gflops according to wiki, and the 7770 is 1000 mhz with 1250 gflops. Paper wise, the gpu would be like a modified OC 7750.
Well to be realistic Sony probably couldn't sell massive quantities of consoles with two 680's even though it would be insane. Still nice too know pc gaming will be where the real capabilities are rather than lame consoles.
++ In the past console makers have not depended on the hardware designer for manufacturing capacity too. For example the Cell BE processor in the PS3 (and the RSX from NVidia) are manufactured in Japan by a FAB that Sony themselves own, not by IBM's FAB in New York (who designed the Cell BE) or by TSMC (NVidia's normal manufacturing partner).
That being said, 90nm FABs were a lot cheaper than 32/28nm FABS, so it is very likely that this may be different for upcoming console generations, so SONY/AMD may be using GlobalFoundries for this APU after all!
++ Tahiti is the codename for the 7970/50 architecture. So this looks to be a downclocked version of the 7950 most likely. For this though the 7800 series architecture would be better suited as Tahiti's Compute sections would be completely wasted here in a pure gaming machine!!
to expensive
not fast enough
it will hold back the development of high end games as the PS3 did
Considering the fact that AMD has cut their exclusivity agreement with Global Foundries for 28 nm APUs I doubt that's going to be a problem. TH News Link about it: http://www.tomshardware.com/news/amd-globalfoundries-28nm-radeon-processors,15404.html

That's a next year model, so why should it be impossible?
