If you want to know the PS4 specs I suggest the following...
1) Google PS4 specs, and read whatever you want.
2) Take all info with a large grain of salt
3) Go into a coma for about 6 months, or freeze yourself like Cartman http://www.youtube.com/watch?v=fnsq1LWKeVI
4) Wake up to real PS4 specs
From what I have seem th ePS4 & next Xbox will both have 8 core AMD jaguar chips (AMDs answer to atom) not bulldozer or even close and the graphics will be at most half as powerful as a 7970. Its the developer kits that have bulldozer cores as the jaguar ones don't exist yet.
From my understanding, those are the specs of the dev kits. The dev kits will have more powerful hardware when compared to the production models.
It would be interesting if someone was to pull up the specs of the dev kits for the xbox 360 or ps3 and see how those compared to the actual consumer console.
The Apple Power Mac G5 is based upon two of IBM's 64-bit Power PC processors
and features ATi RADEON 9800 Pro (R350) graphics. However the R350 is
believed to be an interim solution and will, in due course, be superseded by
the forthcoming ATI R420."
