Rumors have been running rampant for several years regarding the PS4 specs. As we get closer to the PlayStation 4 release date more accurate reports are coming in.

Sources at Kotaku have indicated the PS4 will have an AMD x64 CPU and 28nm AMD Southern Islands graphics power. This report has created quite a stir in the Sony community considering there are more powerful AMD chips that could be used.

A reliable source from IGN believes the console will have AMD’s A8-3850 APU and a Radeon HD 7670 GPU. The HD 7670 would be an upgrade over the rumored HD 6670 card in the Xbox 720. To put into context what the HD 7670 is capable of, a benchmark tests for HD 6670 for Metro 2033 and Crysis set to a resolution of 1920×1080 (1080p) is 30 frames-per-second. The HD 7670 supports HDMI1.4a output, which is required for PS4′s rumored 4k resolution.

The official PlayStation 4 launch specifications are expected to be much better than has been reported by Kotaku and IGN. Based on those specs given the PS4 would not be able to support both the 4K gaming and full HD 1080p 3D gaming, unless a multi-GPU would be used.

Rumors have suggested that there will no backwards compatibility and Sony will focus strictly on next generation. The company has previously said it was too expensive to offer this feature.

There have been talks of removing second hand games from PS4 by having games tied to your SEN account. Michael Pachter has said he spoken with SCEA president Jack Tretton and that he “completely opposes” blocking used games. No official word from Sony yet on PS4 blocking used games.

VGLeaks has released a spec sheet that is rumored to be for the PS4 alpha kits sent to developers.
