蓝宝今天又推出了一款超频版的“SAPPHIRE HD 7970 OC 3GB GDDR5”，主打强力散热器“Dual-X”，采用了所谓的全新技术“dual-extractor”，配备两个大型风扇、五条纯铜热管、纯铜底座和密集铝质鳍片，还加装散热片专门照顾显存、供电电路，号称可在日常操作环境下提供清凉安静的环境，而在极限负载下又能发挥出色的散热效率。

该卡依然采用了AMD原厂公版方案的PCB，不过和迪兰一样也补足了供电系统，从5+1相增强为6+1相，而在频率方面通过双BIOS提供两个档次，默认情况下核心超到950MHz，显存升至5700MHz，切换后则可进一步达到核心1000MHz、显存5800MHz，分别比公版高出75MHz、300MHz。

显存容量自然还是3GB GDDR5，输出接口也是双链接DVI、HDMI、两个miniDP，转接头提供了DVI/VGA、miniDP/DP、miniDP/SL-DVI、HDMI/SL-DVI。
