外置显卡藏身光驱索尼旗舰新VAIO Z解密

下面终于要讲到最特别的Power Media Dock扩展坞。从外观上来看，它就像是普通的轻薄笔记本外置光驱（可选DVD刻录或蓝光Combo）。但实际上，其内部还包含了AMD Radeon HD 6650M独立显卡，与主机间的沟通则是通过Light Peak光纤接口。

没错，就是由Intel、苹果合作开发的Light Peak，在苹果Mac机身上叫做Thunderbolt。索尼VAIO Z是首款使用该接口的非苹果机型，没有使用苹果的Thunderbolt名称，而是直接以研发代号“Light Peak”称呼。

在实现上，索尼和苹果对待Light Peak也有明显区别。苹果是将该接口集成在Mini DisplayPort接口中，使用铜线连接，可兼顾视频信号、数据信号和供电。而索尼则是将将该接口集成在VAIO Z机身右侧的USB 3.0接口内，并使用光纤连接。
