[XF] 冰魄戰將 Sapphire藍寶 Vapor-X HD 7970 GHz Edition 3GB GDDR5 顯示卡
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。
p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

p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

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

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

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

與GPU的接觸面可不是一般銅底，而是均熱板的腔體

出了均熱板之外還動用了6mm和8mm的熱導管各兩根，其散熱效率可見一斑

p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!
E 插個頭香!!
散熱器外殼好炫~
有隱形戰機的感覺
:good 果真是好卡一張啊~~~ 基本上這種東西看看就好.... 7970又有一個新的選擇了！！ 是我被養壞了?;P..
看到這數字,沒有被嚇到耶:lol
