智慧型手機(Smartphone)、平板電腦(Tablet PC)等行動裝置帶起的行動風潮對個人電腦
(PC)市場造成衝擊,無法像筆記型電腦(NB)一樣可帶著走的桌上型電腦(DT)所受衝擊更是
明顯。或許正因如此,PC晶片龍頭英特爾(Intel)似乎也開始準備棄守DT晶片市場,並積極
搶攻行動晶片市場,好穩住公司江山。
媒體CNET編輯Brooke Crothers近日特地撰文討論英特爾未來發展策略。Crothers引述一名
美國PC通路商的消息,表示英特爾下一代微處理器架構Broadwell 將以行動平台為主,所
以不會針對DT平台推出產品。
對英特爾這樣一家PC晶片龍頭廠來說,不在DT平台上推出晶片的確是前所未見。不過要就
此說DT晶片或甚至DT將死可能還太早。至少在Broadwell繼任微處理器架構Skylake於2015
年推出,並於2016年由Skymont繼任前,英特爾還是會繼續推出DT晶片。
在英特爾逐漸減少供應DT晶片同時,該公司可能於2013年推出的下一代Atom系統單晶片
(SoC)Bay Trail則在效能上離DT等級晶片更進一步,而且還兼具了低耗電特性。半導體新
聞媒體Insight64總分析師Nathan Brookwood曾批評英特爾Atom晶片為了達到低耗電目的,
遂過度犧牲效能,不過英特爾在Bay Trail這一代Atom晶片重新設計,好改善效能不佳問題
。
近日傳出英特爾為平板電腦設計的新一代22奈米製程Atom平台片Bay Trail-T會使用4顆
Silvermont核心,核心時脈達到2.1GHz,效能和能耗表現都較目前的Clover Tail好上不少
,預定上市時間為2014年,但最快可望於2013年底搶市。
英特爾資深院士Mark Bohr近日在國際電子元件大會(International Electron Device
Meeting;IEDM)宣布將把目前僅用於Ivy Bridge處理器的22奈米立體3閘(Tri-Gate)電晶體
技術首度用於旗下系統單晶片產品,也就是Atom晶片上。根據Bohr說法,使用3D電晶體技
術的系統單晶片在效能、耗電上將能大幅勝過對手。雖然Bohr並未指明首批使用3D電晶體
技術的系統單晶片為何,不過他指的應該就是預定於2013年推出、代號為Silvermont的
Atom處理器。
Crothers認為大膽點來說,或許能說英特爾已把未來賭在Bay Trail這個能用於行動裝置、
伺服器上的平台。雖然2016年前DT還不至於成為歷史,不過隨著英特爾焦點逐漸轉移至行
動晶片,恐怕DT晶片和DT離走入歷史也已然不遠。
AMD呢?
有什麼動作嗎?
他們現在在幹嘛
