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
Хотя по мне, если останется PS Plus и совместимость со старым поколением, то мой выбор в пользу PS4
