唉，不得不承认现在的索尼早已不是当初的索尼了

帮楼主补充一个PS4(Orbis)的开发路线图


http://www.vgleaks.com/orbis-roadmap/

VGLeaks has released a product roadmap for ORBIS "PlayStation 4" citing the product lifecycle beginning as early as 2011.

Quote:
2011 June/July – PC with Win7 64-bit and a “jailbroken” ATI r9 graphics card
2011 Sept/Oct – PC with Win7 64-bit and a “jailbroken” ATI r10 graphics card
2012 Q1 – disclosure to more developers
2012 E3 – potential unveiling window start
2012 Jul – devkits for engineers writing OS
2012 Q3 – first true hardware prototype devkits
2013 E3 – potential unveiling window end
2013 Q4 – launch
The full article is at the URL posted at the top.

PS: Any idea what "Jailbroken" means with respect to the article?

EDIT: Thanks to sTeLioSco for finding this!

EDIT 2: Rumour Round Up:

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.

For more information, Jeff Rigby's rumour roundup.

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

Explanation: 720 has a lower clock, but more cores. 720 has more but SLOWER RAM. DDR3 RAM is usually good for things like multitasking etc....It is expected to be based on Windows 8 as well.

Note: GDDR ram is more suitable for Graphics Processing (In PS4), and DDR3 is more suitable for OS Tasks (720). It is expected that the 720 may need some sort of ES/ED Ram to compensate. Basically, don't get caught up in the RAM size but the RAM type.

Note 2: Until OS features etc... are revealed. Nothing concrete can be determined BUT at this point, we can assume both systems would have similar performance.

Update: Added some more info regarding PS4, because apparently my OP makes the PS4 look like shit and has caused confusion hahaha

还是希望骚尼的PS4给力点
