[XF] GHz威能 Sapphire藍寶 HD 7970 OC 3GB GDDR5 顯示卡評測
為了不讓NVIDIA GeForce GTX 680專美於前,AMD再度推出GHz版的Radeon HD 7970,但其實各家AIC早已生產出幾款超版的顯示卡,其中不乏核心時脈達到GHz的款式。
AMD顯示卡專業製造商--Sapphire藍寶發表出廠預設即超頻的HD 7970 OC 3GB GDDR5顯示卡,預設核心時脈已超頻至950MHz,透過切換器還可載入時脈達1GHz的BIOS設定值!

p外觀與散熱
看起來相當具有威力的散熱器,使用Dual-X兩顆90mm風扇進行散熱,經過設計的扇葉同時保有散熱力與寧靜度

視訊輸出介面有DVI-I DL、標準HDMI 1.4與2組mini DisplayPort 1.2
https://picx.xfastest.com/elvis/Graphic/Sapphire/HD7970-OC/06.jpg
從這個角度可見整體散熱器的厚度比標準雙槽還略厚一些
顯示卡頂部可見PCI-E 8 pin與6 pin電源輸入端子各1組
https://picx.xfastest.com/elvis/Graphic/Sapphire/HD7970-OC/07.jpg
導風罩的稜線造型相當好看,長度略為超過PCB

卸下散熱器
https://picx.xfastest.com/elvis/Graphic/Sapphire/HD7970-OC/10.jpg
散熱器與GPU接觸面為全銅底,使用5根熱導管與鋁鰭構成
https://picx.xfastest.com/elvis/Graphic/Sapphire/HD7970-OC/11.jpg
可以發現熱導管徑幾乎沒有太大的變形,可以維持完整的散熱效率
靠外側的兩根熱導管直徑更達8mm

p小結
Sapphire藍寶 HD 7970 OC版的時脈相對於公版有所提升,性能表現自然比較好,甚至可以跟當前的GPU之王nVIDIA GeForce GTX 680不相上下。
而Sapphire自家的5根熱導管搭配Dual-X雙風扇散熱設計,讓這張顯示卡燒機時的溫度可以壓得比公版還要低,讓人眼睛為之一亮。
喜愛AMD卡王的朋友可千萬不能錯過Sapphire藍寶這張HD 7970 OC顯示卡!!E 評測效率真快
期待預設GHZ版的評測 MOS 的散熱片上還挺有誠意的
有些都只是用個鋁板 都沒作鰭片
