嵌入式處理器效能指針聯(lián)盟(Embedded Microprocessor Benchmark Consortium，EEMBC)完成了一個數(shù)據(jù)庫，收集來自1,500款Android手機與平板電腦的處理器效能比較信息，采用在 2012年12月底所釋出的一款新量測工具。而現(xiàn)在EEMBC正準備推出更新版的Android效能指針工具，未來將可展現(xiàn)更多Android移動裝置在系統(tǒng)層級的效能差異細節(jié)。 EEMBC在2012年12月發(fā)表的新1.0版 AndEBench 會自動將Android裝置性能量測結果公布在EEMBC官方網站的一個開放性線上數(shù)據(jù)庫；在主處理器性能方面，華碩(Asus)的PadFone 2 目前是排行榜第一名，分數(shù)達11,558，但該產品事實上并未獲得太高的市場注意度。 三星(Samsung) 的Galaxy系列與LG的Optimus，還有一款夏普(Sharp)的手機以些微差距分別排名第二、第三與第四，分數(shù)在11,367至10,334之 間。而其它來自眾多制造商的不同種類裝置，性能表現(xiàn)分數(shù)則差異較大；如Google的Nexus 7與10，主處理器性能指針分數(shù)分別為8,565與6,650，摩托羅拉(Motorola)的Defy XT手機主處理器性能則敬陪末座，僅96分。 在Java性能表現(xiàn)方面，華為(Huawei)的Ascend D1 Quad拿到458的最高分；其后則為數(shù)款三星Galaxy系列產品與LG的Optimus系列手機，分數(shù)在405~370分之間。Google的 Nexus 7與10的在這個項目得分較高，分別拿到303與378分。 該數(shù)據(jù)庫顯示，高通(Qualcomm)的平臺被眾多供貨商與區(qū)域市場的手機所廣泛應用；此外也顯示在美國，以及中國、印度有許多不知名的手機供貨商。 據(jù)了解，下一版的AndEBench會在處理器性能之外，加入內存、繪圖處理器以及其它系統(tǒng)功能的性能量測指針，包括GUI渲染(rendering)、XML解析(parsing)以及加密法的性能量測。此外該工具還將針對移動裝置如何處理特定任務提出報告，并以分鏡表(story board)來呈現(xiàn)裝置在執(zhí)行任務時是如何各個擊破重點。 目前還不清楚新版本工具何時會發(fā)布，其開發(fā)小組是由來自英特爾 (Intel)的Android專家Ronen Zohar領軍。AndEBench可以透過GooglePlay與亞馬遜(Amazon)的Android應用程序商店免費下載；該工具開發(fā)小組也歡迎 EEMBC成員加入，但要加入該聯(lián)盟，第一年年費需繳交7500美元。 本文授權編譯自EE Times，版權所有，謝絕轉載 編譯：Judith Cheng 參考英文原文：Android benchmark gets update, publishes online，by Rick Merritt

{pagination} Android benchmark gets update, publishes online Rick Merritt SAN JOSE, Calif. -- The Embedded Microprocessor Benchmark Consortium has gathered a database comparing processor performance of some 1,500 Android phones and tablets using a new tool released in late December. Now EEMBC is working on an update of its Android benchmark that will show more nuances of Android mobile device performance at the system level. The December update to version 1.0 of the AndEBench automatically posts results after it is run to an open, online database on the EEMBC Web site. In terms of native processor performance, the Asus PadFone 2 currently tops the list with a score of 11,558, despite the fact it has relatively little market traction. Members of Samsung’s Galaxy family, LG’s Optimus handsets and a Sharp phone are closely packed into second, third and fourth places with scores ranging from 11,367 to 10,334. A wide variety of other devices from many manufactures are scattered out across the performance spectrum. Google’s Nexus 7 and 10 ranked relatively low on the native benchmark at 8,565 and 6,650 respectively. The Motorola Defy XT handset is the dog of the group, scoring just 96 points. In terms of Java performance, the Huawei Ascend D1 Quad tops the list at 458. It is again followed by several Samsung Galaxy and LG Optimus handsets at 405 to 370. Google’s Nexus 7 and 10 fare somewhat better here with scores of 303 and 378 respectively. The database shows Qualcomm’s wide use among phones from many vendors and geographies. It also shows a wide variety of vendors unknown in the U.S., mainly from China and India. The next version of AndEBench will measure memory, graphics and other system features in addition to processor performance, including tasks such as GUI rendering, XML parsing and cryptography. It will also report on how a device handles a specific task, breaking down each major point in processing the job in a story board format. It’s unclear when the new version will be ready. The working group behind it, chaired by Ronen Zohar, an Intel Android specialist, is well attended, said an EEMBC spokesman. AndEBench can be downloaded for free from GooglePlay and the Amazon Appstore for Android. The working group is open to new participants willing to become EEMBC members at a cost of $7,500 for the first year.
