冰魄戰將好讀版 http://www.xfastest.com/forum.php?mod=viewthread&tid=84399&fromuid=38227 =============================================================================== Sapphire藍寶科技是最率先運用Vapor Chamber(均熱版)在顯示卡散熱的品牌， Vapor-X則是隨之誕生的散熱技術名稱，藉由均熱版能以平面的方式接觸迅速帶走熱量， 配合良好設計的散熱片可以輕鬆壓制顯示卡運作時所產生的高熱。 對應AMD目前最高階的HD 7970 GHz Edition，當然少不了Vapor-X登場的機會， 這回再加上Dual-X雙散熱風扇更是如虎添翼， 以下我們使用3GB的版本進行開箱介紹與效能實測。 包裝與配件 由於Vapor-X產品線在Sapphire的規劃裡定位幾乎算是最高階， 因此外盒採用燙銀色的底層塗裝，看起來格外精緻 http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/01.jpg

http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/04.jpg 外觀與散熱 使用Dual-X雙散熱風扇設計，風扇直徑達90mm，導風罩造型類似層層相疊的閃電/箭頭狀 http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/05.jpg 視訊輸出介面採用和NVIDIA GeForce 600系列高階機種一樣的配置， 有DisplayPort 1.2、HDMI 1.4a、DVI-I和DVI-D各一組，都是標準接頭 http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/06.jpg 顯示卡頂端可見防彎鋼條設計，電源輸入使用6pin與8pin各1組 http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/07.jpg 顯示卡背面可見導風罩寬度略微超過PCB，此空間可讓廢熱風流有明確的導向， 不會堆積在顯示卡週圍 http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/08.jpg 卸下散熱器

http://picx.xfastest.com/elvis/Graphic/Sapphire/VaporX-HD7970-3GB/Power.png 小結 從以上測試數據來看，GHz Edition確實在性能方面有所提升， 而且這張卡還可將時脈超頻至1050MHz。 然而為了超頻勢必得將供電輸出拉高，燒機時的耗電多了不少， 但溫度狀況反而比公版不超頻還低，由此可見Vapor-X散熱技術的威力， 對於想要顯示卡同時擁有絕佳性能與涼爽溫度的玩家來說， Sapphire Vapor-X HD 7970 GHz Edition相當值得推薦選用! -- --
