继之前外媒泄漏的PS4硬件配置情报，IGN今日声称已确认了报道，同时获悉了具体的芯片型号，包括采用AMD的A8-3850 APU和HD 7670 GPU芯片。

A8-3850 APU芯片包含四核的2.9GHz频率的CPU，同时集成了一个图形芯片，将与独立显卡共同运作，就是HD 7670。该显卡芯片是一款DirectX 11显卡，时钟频率为1GHz，1GB VRAM存储器。支持HDMI 1.4a版本的输出等。

线人表示，HD 7670是2011年发售的HD 6670的定制版，拥有特定的频率和配置等，据悉微软的新一代主机Xbox720也采用了相同的显卡芯片。

A8-3850 APU集成的图形芯片型号为HD 6550D，也就是说APU可独立运行游戏，只不过图形水准和分辨率较低。当然，和HD 7670共同处理的话，将可实时渲染非常强悍的游戏画质。

此前报道称，PS4代号为“地球”，支持4096x2160的分辨率，将在2013年末上市。

分析：这配置我只能说是坑爹！！极度坑爹！！128bit的HD7670显卡768 GFLOPS的能力跟PS3上的128bit G71比起来也好不了多少，PS3整机单精度浮点超过1T FLOPS，PS4的整机性能可能仅仅比PS3强一点点，甚至不如WIIU！！尼玛这配置不但虚幻4跑不了，CRYTEK的CRY ENGINE 3也够呛，各种缩水+低帧率目指！！更重要的是这种配置还要到2013年年末才能上市！！而且起码会用到2020年！！！绝壁拖累PC图形技术发展10年以上！！这货还是次世代主机么？PS3.5都不算！！顶多PS3.2！！技术的骚尼已经变成了坑爹的骚尼！！
