"Durango is 1.23 TF, HSA + Large Cache's + DSPs, 8 GB DDR3 + ES RAM. Add in some special 'sauce' to get it to work better if you code to metal.
Orbis is 1.84 TF, 4 GB GDDR5, and an unknown as of now 4 Steamroller or 8 Jaguar Core unit."
Pulled that data from a thread in GAF. Its a basic summary of the latest info in GAF from all rumors and of course data give by people in the know who are in GAF. However, the PS4 one is a theoretical limit and more than likely won't approach 1.84TF... probably closer to the 1 to 1.2TF area I've considered all along.
EDIT... same info in better detail
PS4 "Orbis"
- AMD x86 3.2GHz APU Solution (Jaguar/Steamroller), 4 cores (2 core pairs), [Higher Clock than X720/Durango]
- Maybe AMD 8000 series GPU solution [Customised Solution Possibly utilising GPU + APU combo]
- 2-4GB GDDR5
- Launch Fall 2013/Early 2014
Explanation: PS4 has a higher clock, but less cores and is using an APU solution (CPU & GPU elements combined onto a single chip). The PS4 has less RAM but is using faster GDDR ram, so the overall performance should be a wash.
Xbox 720 "Durango"
- AMD x86 Jaguar 1.6GHZ 8-Core [Targeting one core being dedicated for OS tasks]
- AMD 8000 series GPU
- ESRAM on the GPU (unknown amount)
- 8GB Ram DDR3, [1.5GB of RAM likely reserved for the operating system]
- Launch 2013
