主流笔记本不同模式功耗对比测试节能模式不低能主流笔记本不同模式功耗对比测试笔记本用户越来越多了,很多用户喜欢安装诸如《鲁大师》之类的软件检测笔记本的整机功耗。但是此类测试软件给出的都是估值,和实际测试结果究竟有多大误差很少人知道,不同配置笔记本的功耗差异又有多大?而且面对笔记本内置的多种电源调节模式,那种才是均衡功耗和性能的最佳寺找,影响笔记本功耗的关键有在哪里?多款配置功耗实测为了贴近大家的使用需求,此次功耗测试我们引入了多款配置。如CedarTrail平台的上网本、配备GTM独立显卡的英寸主流本、神舟Ultrabook超极本、配备英特尔HD核心显卡和GTM独显的Optimus双显卡切换笔记本。在测试过程中,我将模拟用户针对不同的应用进行测试,如静置状态、处理器和显卡满负荷状态、视频播放,同时还将测试不同电源模式、不同屏幕亮度下的功耗。此次测试,我将借助专业的功耗仪,计算上述应用下的耗电量戒功耗大小。另外,还会针对《鲁大师》等带有功耗估算功能的软件进行测试,查看此类软件估计出来的功耗和设计测试结果究竟有多大的误差。测试机型及配置如下:软件计算功耗误差惊人首先对软件估算的功耗进行实测。我在神舟优雅APi上安装了《鲁大师》软件,系统根据硬件配置自动列出了清单,给出了每个配件的功耗和整机的功耗,《鲁大师》将每个配件的功耗值简单相加,即得到最终功耗为W。andduediligenceevaluationsarticlendheadoffice,branch(jurisdiction),riskmanagement,marketingmanagementbranchwithintheDepartment'screditbusinesspersonassumedresponsibilityforthesupervisionandinspectionandduediligenceevaluationsArticlerd,HeadOffice,branches(jurisdiction),riskmanagement,MarketingManagementDepartmentthroughonsiteandoffsiteinspection,investigationreport,interviewswithinvestigatorsforpreloaninvestigationworkbywayofconductingsupervisionandinspection,qualityevaluationpreloaninvestigationwork,andbasedontheevaluationresults,theimplementationofdiversitymanagementththecontrolandinspection(a)theimplementationofthecreditsystem:thereisnobreachofcreditpolicyrelatingtothegrantingofcreditandtheheadoffice(B)dualcreditrating:timelinessofratings,whethertheprovisionsoftherating,ratingresultsareaccurate(C)thesurveycontents:datacollectioniscomplete,reportwritingiscomprehensive,indicatorsanalysisisobjective,real,conclusionsandthefactsareconsistentandreasonable(D)doubleimplementationofinvestigationssystem:practicalimplementationofdoublesystem(E)othersupervisionandinspectionofthecontentsthduediligenceevaluationofficesandbranches(jurisdiction),riskmanagement,MarketingManagementDepartmentagreedtocarryoutpreloaninvestigationsupervisionandinspectionwork,evaluatewhetherinvestigatorsduediligencetodeterminewhethertheexemptionshouldbeInvestigatorsshouldbecompatiblewithDuediligenceassessmentshouldbebasedonthefactthat,followingtheprinciplesofobjectivity,impartialityandfairnessArticlethhead为了将系统的功耗调节到最大,我利用软件对处理器和显卡添加满负载,同时将显示屏亮度调节到最大,并开启高性能电源管理模式。此时,用功耗仪测得的整机功耗一直保持在W左右的水平,这个结果和软件检测的W有非常明显的数值差距,误差达到了W。所以,大家面对此类测试软件的功耗估算功能时,必须理性对待。事实上,我们持续在高满负荷状态下运行笔记本,一个小时耗费了度电,按照功耗计算公式,最终的平均功耗为W,和功耗仪实时监控的W基本保持了一致。鲁大师估算的峰值功率为W,和实际测试结果相差较大屏幕亮度对功耗影响很大大家都知道不同的配置和应用会影响最终功耗,但是这个差异有多大呢?如独显笔记本,带有Optimus双显卡切换的笔记本、上网本甚至是超极本。为了体现差别,在测试时将屏幕亮度调节到最大特别说明的例外,并关闭“降低显示亮度”“关闭显示器”“使计算机进入睡眠状态”设置选项。从表的测试结果可以看出,不同机型一个小时耗费的电量差别比较大下文所提到的数字均为每小时的耗电量。在最高性能和静置设置模式下,最耗电的神舟优雅APi一个小时耗费了度电,而最省电的三星NC上网本仅耗费了度电,其中三星NC上网本和神舟飞天U超极本耗电量排在中间位置且耗电量比较接近。接下来我将对不同电源模式和不同屏幕亮度下的笔记本的耗电量进行测试。如在最高性能设置模式下,分别将屏幕亮度调节到最亮和最暗,华硕ASMandduediligenceevaluationsarticlendheadoffice,branch(jurisdiction),riskmanagement,marketingmanagementbranchwithintheDepartment'screditbusinesspersonassumedresponsibilityforthesupervisionandinspectionandduediligenceevaluationsArticlerd,HeadOffice,branches(jurisdiction),riskmanagement,MarketingManagementDepartmentthroughonsiteandoffsiteinspection,investigationreport,interviewswithinvestigatorsforpreloaninvestigationworkbywayofconductingsupervisionandinspection,qualityevaluationpreloaninvestigationwork,andbasedontheevaluationresults,theimplementationofdiversitymanagementththecontrolandinspection(a)theimplementationofthecreditsystem:thereisnobreachofcreditpolicyrelatingtothegrantingofcreditandtheheadoffice(B)dualcreditrating:timelinessofratings,whethertheprovisionsoftherating,ratingresultsareaccurate(C)thesurveycontents:datacollectioniscomplete,reportwritingiscomprehensive,indicatorsanalysisisobjective,real,conclusionsandthefactsareconsistentandreasonable(D)doubleimplementationofinvestigationssystem:practicalimplementationofdoublesystem(E)othersupervisionandinspectionofthecontentsthduediligenceevaluationofficesandbranches(jurisdiction),riskmanagement,MarketingManagementDepartmentagreedtocarryoutpreloaninvestigationsupervisionandinspectionwork,evaluatewhetherinvestigatorsduediligencetodeterminewhethertheexemptionshouldbeInvestigatorsshouldbecompatiblewithDuediligenceassessmentshouldbebasedonthefactthat,followingtheprinciplesofobjectivity,impartialityandfairnessArticlethhead一个小时的耗电量分别为度和度,差别明显。同时对比其他三个平台在最高亮度和最低亮度下的耗电量,也能得到类似的结果,由此可以看出屏幕亮度对功耗的影响还是较大的,其中英寸机型的功耗差异明显要大于英寸的上网本。但是如果我们保持屏幕最大亮度不变,将电源模式调节为节能模式,此时除了带有双显卡切换功能的神舟优雅APi耗电量下降比较明显外,其他三款机型的耗电量和最高性能设置下基本上没有什么变化,如华硕ASM最高性能和节能模式下的耗电量分别为度和度。所以,对于非双显卡切换机型来说,静置模式下不同电源模式的耗电量差异并不大。说明:带有Optimus智能双显卡切换的神舟优雅Ai笔记本,采用“自动选择”模式的显卡全局设置。上述测试笔记本屏幕均采用全亮度设置。双显卡切换机型功耗对比从上面的耗电量测试可以看出,单显卡机型和双显卡切换机型之间还是存在一定的区别,为此我利用神舟优雅APi笔记本对不同显卡模式下的功耗进行测试。从表可以看出,采用“自动选择”的显卡切换模式后,神舟优雅APi最高性能模式下的耗电量为度,但是此时如果保持屏幕最高亮度不变,将电源模式调节为节能模式后,耗电量则有大幅度下降,为度,。通过实时监测的功耗发现,在节能模式下,这款机型的功耗约为W,在最高性能模式下的功耗约为W,两者之间的功耗差别达到了W。另外,从表的测试可以看出,在静置条件下,不管我们使用何种显卡切换模式,在各种模式下实测的电源功耗值基本上都是相同的,最高性能和平衡模式设置的功耗值同样接近,只有在节能模式下整机的功耗最小。andduediligenceevaluationsarticlendheadoffice,branch(jurisdiction),riskmanagement,marketingmanagementbranchwithintheDepartment'screditbusinesspersonassumedresponsibilityforthesupervisionandinspectionand
