冰魄战将好读版 http://www.xfastest.com/forum.php?mod=viewthread&tid=84399&fromuid=38227 =============================================================================== Sapphire蓝宝科技是最率先运用Vapor Chamber(均热版)在显示卡散热的品牌， Vapor-X则是随之诞生的散热技术名称，藉由均热版能以平面的方式接触迅速带走热量， 配合良好设计的散热片可以轻松压制显示卡运作时所产生的高热。 对应AMD目前最高阶的HD 7970 GHz Edition，当然少不了Vapor-X登场的机会， 这回再加上Dual-X双散热风扇更是如虎添翼， 以下我们使用3GB的版本进行开箱介绍与效能实测。 包装与配件 由於Vapor-X产品线在Sapphire的规划里定位几乎算是最高阶， 因此外盒采用烫银色的底层涂装，看起来格外精致 http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/01.jpg

http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/Power.png 小结 从以上测试数据来看，GHz Edition确实在性能方面有所提升， 而且这张卡还可将时脉超频至1050MHz。 然而为了超频势必得将供电输出拉高，烧机时的耗电多了不少， 但温度状况反而比公版不超频还低，由此可见Vapor-X散热技术的威力， 对於想要显示卡同时拥有绝佳性能与凉爽温度的玩家来说， Sapphire Vapor-X HD 7970 GHz Edition相当值得推荐选用! -- --
