中階顯卡寂靜新選擇-TurboDuo R9 270 2GB - 3C

好讀網址:http://www.xfastest.com/thread-134439-1-1.html

前言:
AMD推出R9系列後，許多廠商紛紛推出R9 270系列產品，R9 270簡單說就是R9 270X降頻版
，核心部分無閹割為Pitcaim核心，擁有1280個串流處理器，功耗比R9 270X低30W為150W
這次介紹的PowerColor TurboDuo R9 270 2GB OC，在散熱上下了不少功夫，採用
TurboDuo散熱技術，具備兩顆8公分大風扇，展現優於公版之19%散熱效能提升及8%運行噪
音降低之表現
用料方面採用高規格黃金用料，其中包含多相供電設計、高品質亞鐵鹽芯電感和
PowerPAK SO-8封裝MOSFET，可大幅提升整體超頻效能及穩定性，核心時脈為930 MHz，透
過Boost可達955 MHz，並搭配2GB GDDR5記憶體與1400MHz記憶體時脈
強化散熱與用料還有原廠Boost後的R9 270有怎樣的表現就讓我們繼續看下去嚕^^

戲，畫面來說細節還不差，跑起來真的很順暢，沒有半點延遲現象產生

http://www.xfastest.com/images/xftitle.png[b][size=5]總結[/size][/b]
這張撼訊PowerColor TurboDuo R9 270 2GB OC在用料上下了不少工夫，電源方面採用高
規格黃金用料，包含多相供電設計、高品質亞鐵鹽芯電感和PowerPAK SO-8封裝MOSFET，
可大幅提升整體超頻效能及穩定性

散熱方面採用兩顆8公分風扇並搭配大面積鋁製鰭片有效率地降低溫度，展現優於版之19%
散熱效能提升及8%運行噪音降低之表現，使用FurMark燒機最高溫僅69度 且風扇聲音相當
安靜，幾乎感覺不出來顯示卡在全速運轉!!

在測試過程中表現很不錯，效能達到一定的水準，且原廠預設含Boost功能，效能比公版
卡表現更佳，許多遊戲都可以維持不錯的效能水準，已可滿足一般消費者在大部分遊戲的
順暢度，在BF4與Thief實際測試流暢度中，表現還不錯，玩起來非常順暢，場景與畫面細
節表現也相當不錯，這部分可以給需要的玩家做參考

在價格方面PowerColor TurboDuo R9 270 2GB OC這張在系列的價格較為漂亮的一款產品
，與其他廠牌價格相差有500~1000元左右的差價，且為短卡設計，非常適合安裝在HTPC主
機內，原廠出廠提供Boost功能，讓效能表現更加出色，縮短了與R9 270X的效能差距，當
然有興趣的玩家可以透過第三方軟體來做超頻，相信會有更佳的表現，但別忘了散熱方面
還是要注意；有這樣的效能與漂亮的價格大大提升了這款PowerColor TurboDuo R9 270
2GB OC的CP值

整體來說中階卡定位的撼訊PowerColor TurboDuo R9 270 2GB OC表現不錯，除了有良好
的散熱系統與電源用料外，原廠還提供了Boost功能，讓效能更上一層樓，撼訊原廠提供3
年保固，後續維修與保固上有一定的保障

以上感謝賞文^^謝謝大家
