NVIDIA移動(dòng)業(yè)務(wù)部門總經(jīng)理Mike Rayfield表示:“當(dāng)今的消費(fèi)者希望便攜計(jì)算設(shè)備能夠根據(jù)他們特定的需求進(jìn)行量身定制,同時(shí)還能提供與臺(tái)式個(gè)人電腦同樣生動(dòng)和迷人的體驗(yàn)。融合了高性能和超低功耗的NVIDIA Tegra是世界上最小的、全高清片上電腦,同時(shí)對(duì)于那些希望為一直聯(lián)網(wǎng)的新一代消費(fèi)者設(shè)計(jì)出功能豐富、外形小巧優(yōu)雅的便攜設(shè)備的產(chǎn)品制造商而言,它也是一個(gè)理想的選擇?！?p>
ARM首席執(zhí)行官Warren East表示:“今天,基于ARM處理器技術(shù)的NVIDIA Tegra的發(fā)布,是我們與NVIDIA長(zhǎng)期且富有成果的合作關(guān)系的一個(gè)證明。NVIDIA是第一批授權(quán)使用ARM11 MPCore多核處理器技術(shù)的合作伙伴之一。NVIDIA Tegra的發(fā)布標(biāo)志著在推動(dòng)下一代計(jì)算變革的道路上邁出的重要一步,這場(chǎng)變革是由具有超低功耗、超便攜性的移動(dòng)互聯(lián)網(wǎng)設(shè)備所推動(dòng)的,ARM也為自己能夠身處這一改變未來游戲規(guī)則的技術(shù)核心而深感自豪?！?p>
ARM稱MPCore多核處理器技術(shù)被設(shè)計(jì)用以將靈活性、性能、功耗效率和功能性推向了一個(gè)前所未有的水平,尤其適合智能手機(jī)和MID應(yīng)用。
ARM11 MPCore多核處理器可根據(jù)具體應(yīng)用的需求在單核至四核的范圍內(nèi)進(jìn)行自由配置。ARM11 MPCore處理器這一獨(dú)特的可擴(kuò)展性為設(shè)備OEM廠商提供了最適宜于其應(yīng)用的性能水平,同時(shí)它允許每個(gè)處理器分別進(jìn)入待機(jī)、睡眠或關(guān)機(jī)的能源管理模式,用于幫助控制處理器消耗的動(dòng)態(tài)和靜態(tài)能源。
以下視頻是一段對(duì)比Intel芯片和NVidia Tegra芯片功耗的視頻,由NVidia工程師錄制:(需要安裝Flash播放器)
以下是摘要一些網(wǎng)友對(duì)該視頻的評(píng)論:
1. That looks really awesome. Please provide more videos, more details. Is it an ARM + DSP based system? Can you have an embedded Linux type OS run on it? Are you measuring 1.3W on your Nvidia laptop including the power consumption of an LED backlit screen? What is the power consumption for browsing the Internet and writing documents? Why aren't you working with OLPC to create the next generation HD-capable lower power and lower priced laptop?
2. oh ffs, you wanna compare a motherboard with a video chip? cmon... and i hope you don't expect me (or anyone else) to blindly believe those power measurements without any details. i am a big fan of you guys but this is too much.
3. I don't think he's measuring the display power on either as either of those just the main board power.
The intel board looks like an Atom or A110 from the chip die I guess the GMA must use a fair amount of power when playing video but then a typical north bridge does use about 7 watts or so plus the GMA 950 or what ever.
If the entire tegra system including display driver is using just 1.3 watts that is extremely impressive.
