今年2月初AMD发布中低端DX11显卡Radeon HD 5570时，曾预告还有另一款姊妹产品Radeon HD 5550。不过当时仅有迪兰恒进一家宣布了HD 5550，并且没有公布有关流处理器数量等详细的规格信息，我们对其还存有些许疑问。

今天，蓝宝的两款Radeon HD 5550终于正式发布，也揭开了这款新核心的神秘面纱。Radeon HD 5550同样属于AMD 40nm工艺DX11阵营，拥有320个流处理器，核心频率550MHz，比Radeon HD 5570的400SP/650MHz略低。整卡最大功耗40W，显存位宽128bit，可搭配1333MHz DDR3或800MHz DDR2显存。

蓝宝的两款HD 5550型号分别为HD55501G DDR3 PCI-E HDMI/DVI-I/VGA和HD55501G DDR2 PCI-E HDMI/DVI-I/VGA，分别提供1GB DDR3或DDR2显存，提供HDMI、DVI-I和VGA接口。前者为Low-profile刀板卡，尺寸168x96x20mm，后者DDR2版则为168x110x18mm。

事实上，国内昂达今天也已经发布了Radeon HD 5550，DDR3版售价定于499元人民币，预计蓝宝产品价格会略高一些。
