联想ThinkPad E14 G3 AMD笔记本电脑评测--具有Ryzen功能的经济型商务笔记本电脑
联想ThinkPad E14是一款办公笔记本电脑，它不像X系列的设备那样纤细，也没有T系列那样多的功能，但笔记本电脑的价格往往只有其一半，它们提供了你工作所需的所有重要东西。联想还修复了一个主要的抱怨，为新的ThinkPad E14 G3配备了更明亮的显示屏，还有一个可选屏幕，具有100% sRGB覆盖率。
你还得到了来自AMD的全新的Ryzen 5000移动处理器，这保证了一个体面的性能提升。我们对配备Ryzen 5 5500U、16GB内存、512GB PCI-SSD存储以及亮度为300尼特的1080p屏幕的20Y7003SGE型号进行了审查，价格为870欧元。如果你能进入联想的Campus项目，价格会降到790欧元，如果你不需要Windows操作系统，价格甚至会降到640欧元。

机箱--ThinkPad的铝制底盘
联想没有改变底盘，黑色的设计可能显得有点无聊，但它绝对是实用的。你可以注意到在材料方面的低价，因为你得到的是塑料和铝的组合（盖子和底板）。稳定性还是不错的，你不能扭曲或凹陷底板（没有吱吱嘎嘎的声音）。盖子本身也很结实，但我们可以通过对背面的集中压力和扭转尝试来迅速激起图片的变形。铰链调整得很好，只有轻微的弹跳。
光滑的表面触感很好，并不显得廉价，但它们极易受到指纹的影响。如果你不定期清洁，该设备很快就会显得非常难看。没有维修舱口，但你可以拆下整个底板（见维修部分）。总而言之，该机箱给人留下了良好的印象，特别是考虑到价格。
E14 G3是我们对比组中最重和最大的设备；在占地面积方面，它明显更深。USB-C电源适配器的重量约为360克。
连接性 - USB-C和USB 2.0
端口的情况仍然是一样的，尽管我们希望能有一些更新。你得到了一个包括充电功能的USB-C端口，以及DisplayPort和一个全尺寸的HDMI输出，但一个缓慢的USB 2.0端口对于2021年的笔记本电脑来说其实并不合适。更昂贵的ThinkPad型号（如T系列）在这方面肯定有优势。
沟通
联想使用了RealTek公司的Wi-Fi 6模块，但与去年的机型相比，传输速率较低。 去年的型号，它配备了英特尔AX200。它现在是一个1x1模块（160MHz），最大传输速率为866Mbps。在我们审查期间，信号质量一直很好。E14 G3还提供一个千兆以太网端口，但没有WWAN模块可用。

网络摄像头
不出所料，你只得到一个简单的720p网络摄像头（0.9MP），带有机械快门（ThinkShutter），拍摄的照片相当糟糕。还有一个红外摄像头，用于通过Windows Hello进行面部识别。
维护
与以前的ThinkPad E笔记本电脑类似，你可以拆下整个底盖，但这个过程并不简单。在你卸下所有螺丝后，面板仍然非常紧，而且有很多塑料夹子，很容易断裂。其他的ThinkPad型号则更容易打开。
一旦进去，你就可以接触到两个M.2-SSD（2280和2242）以及Wi-Fi模块。你也可以更换内存模块，但单个插槽被隐藏在一个额外的盖子下面。
担保
保修期再次显示了ThinkPad E14的入门级地位，因为我们的测试设备只提供了一年的保修期。你仍然可以以额外的价格延长保修期。E14的一些型号也有两年的保修期。
输入设备 - 目前最好的ThinkPad键盘
ThinkPad E14 G3仍然拥有熟悉而出色的键盘，具有1.8毫米的行程和丰富的反馈。尽管价格低廉，但E14与价格更高的ThinkPad X型号相比有很大的优势，后者现在配备了更浅、更平的键盘。当你大量书写时，你肯定会感到高兴，E14 G3还配备了两级背景照明。
虽然联想为一些新机型配备了更宽的触摸板，但E14仍然配备了较窄的版本（10 x 5.6厘米）。操作起来没有任何问题，点击的声音也给人留下高质量的印象。另一方面，额外的TrackPoint按钮有点摇摆不定。
显示 - E14可提供100%的sRGB值
显示器一直是廉价的ThinkPad E14系列的一个问题。对于一台办公笔记本电脑来说，画质还可以，但亮度在250尼特左右，很难有竞争力。联想现在改善了这种情况，我们的测试装置是默认的IPS屏幕，宣传的亮度为300尼特，我们的测试装置甚至可以达到330尼特。如果你想编辑图片，还有一个可选的面板，完全覆盖sRGB。一些地区还得到一个廉价的TN面板，亮度为250尼特，但我们不推荐这个选项。
哑光面板的主观画面印象很好，明亮的地方看起来没有颗粒感。对比度超过1300:1，我们检测不到PWM闪烁。响应时间不明显，但在黑暗的屏幕上有明显的背光渗漏，特别是在左上角以及右下角的边缘。IPS面板的可视角度稳定性很好。

我们用专业的CalMAN软件对显示器进行了分析，灰度已经非常准确，开箱即用。只有轻微的偏蓝，但用肉眼是看不到的。另一方面，颜色清楚地表明，这是一个廉价的IPS屏幕，色域有限（~60% sRGB），我们可以看到与sRGB参考色彩空间相比的巨大偏差。
我们校准了面板（X-Rite i1 Pro 2），相应的配置文件可以在上面的方框中下载。灰度有了一些改善，但颜色仍然显示出高偏差。
对于一台商务笔记本电脑来说，其画质完全够用，但如果你想用准确的色彩编辑图片，你应该得到可选的100% sRGB的1080p屏幕。

额外的亮度在户外绝对是值得赞赏的，而且你的头部空间更多一点，但你还是应该在阴凉处找一个地方，以获得最舒适的观看体验。
性能 - 配备Ryzen 5000的ThinkPad
处理器 - Ryzen 5 5500U，6个核心
我们的评测设备配备了Ryzen 5 5500U有6个核心（12个线程），最高时钟为4 GHZ。有关该CPU的更多技术信息可在这里.
与采用英特尔CPU的ThinkPad型号相反，功率限制稳定在30W，在持续工作负荷下可以很好地保持这一水平。在Cinebench R15多重循环中的平均时钟是~3.4 GHz，几秒钟后没有性能下降。
Cinebench R15 Multi Loop
新的ThinkPad E14在多核基准测试中击败了对手。基于Tiger Lake 的笔记本电脑要慢得多，甚至45W的处理器也是如此。酷睿i7-10850H中的戴尔Latitude 14也比AMD的芯片慢。然而，如果你只强调一个核心，英特尔芯片则有优势。我们应该提到，英特尔CPU通常受益于短时峰值负载的高功率限制，而E14中的AMD芯片则没有这种情况。在电池供电的情况下，性能不会降低。

系统性能
谈到整体系统性能，新的ThinkPad E14 G3给人留下了深刻印象。合成基准测试的结果证实了我们的主观印象；该设备执行输入的速度非常快，而且系统配置中没有瓶颈。你可以将内存扩展到40GB（8GB板载+1个RAM插槽，最大32GB）。

存储设备
ThinkPad E14 G3有两个SSD插槽。我们的评测单元配备了SK海力士的紧凑型M.2-2242模块（BC711），存储容量为512GB（初始设置后有435GB空闲）。两个驱动器都是通过PCIe-3.0 x4连接的，传输速率很好。由于有空的M.2-2280插槽，如果有必要，升级存储容量是非常容易的。更多的SSD基准测试可以在 这里.

GPU性能--RX Vega 7有小幅改进
Ryzen 5 5500U配备了集成的Radeon RX Vega 7，这基本上是旧的Vega 7我们已经从Ryzen 4000芯片中知道。关于iGPU的更多技术信息可参见这里.性能方面也是如此，这得益于双通道内存配置，但总体上处于预期水平。英特尔的集成Xe Graphics G7，这也是英特尔型号中的ThinkPad E14 G2例如，在合成基准测试中要快一些。
还是有变化的，因为AMD已经提高了集成视频解码器的效率。旧的Vega 7 iGPU在4K视频播放期间的GPU负载约为60%，但新版本低于10%。这也改善了视频播放期间的电池运行时间。英特尔的Xe Graphics G7（约30%的GPU负载）也被打败了。
在较长的工作负荷中，图形性能也很稳定。更多的GPU基准测试可在我们的技术部分 。

排放 - 带有AMD-CPU的E14 G3保持安静
系统噪音
新的E14 G3仍然使用单风扇，它是一个整体上非常安静的设备。与许多基于英特尔的笔记本电脑相比，没有高功率限制，因此在短时峰值负载情况下，风扇通常不会开始旋转。当你同时给CPU和iGPU施加压力时，噪音水平还是很方便的，没有恼人的频率。在我们的测试设备上，我们也没有注意到任何其他电子声音，如线圈啸叫。

温度
尽管有安静的风扇，ThinkPad E14 G3的温度也不会让人感到不舒服。在压力测试中，我们可以确定底部有近50℃的温度，在这种情况下，你不应该把设备放在腿上，但在日常情况下没有限制。当你玩像Witcher 3 这样的游戏时，风扇的速度会低一些，所以机箱的温度甚至会高一些。
我们可以再次看到，在压力测试期间，消耗量平息在30瓦特。大约10分钟后有一些波动，但总的来说，性能非常稳定，没有大的下降。处理器以6倍2.6-2.8GHz的速度运行，iGPU以450MHz的速度运行。在压力测试后没有立即出现性能下降。
(-) The maximum temperature on the upper side is 45.1 °C / 113 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.

(-) Playing The Witcher 3, the average temperature for the upper side is 39.8 °C / 104 F, compared to the device average of 29.5 °C / 85 F.
(±) The palmrests and touchpad can get very hot to the touch with a maximum of 38.8 °C / 101.8 F.

能源管理
耗电量--AMD-ThinkPad的电池运行时间长
我们的消耗测量结果显示有轻微的改进，因为与ThinkPad E14 G2（包括英特尔以及AMD）相比，空闲值相当甚至略好，尽管显示屏更亮。AMD系统在负载下的表现不同，因为短期内没有增加功率限制，所以消耗量很稳定。我们在压力测试中确定高达55W，所以紧凑的65W电源适配器（USB-C）是完全足够的。

电池运行时间
联想将电池容量增加到57Wh，这显然对电池运行时间有积极影响。几乎所有的对手，包括ThinkPad E14 G2的两个型号（包括AMD以及英特尔）都被明显击败。我们在调整亮度为150尼特的Wi-Fi测试中，结果是将近11.5小时，在最大亮度下仍然超过8小时。看来，电池运行时间较短的AMD笔记本电脑已经成为过去式了。视频测试得益于更高效的视频解码器，运行时间几乎达到14小时。

Pros
Cons
结论 - E14 G3具有极高的性价比 Preis-Leistungshammer
第三代ThinkPad E14再次成为一款性价比很高的办公笔记本电脑。你没有得到最高端的规格或最好的材料，但是这款笔记本在重要的部分没有让人失望，它再次配备了一个优秀的键盘，这在许多更昂贵的ThinkPad上已经不存在了。与对手相比，键盘也是一个很大的优势。
CPU升级到AMD Ryzen 5000芯片，提高了性能以及效率，结合更大的电池，你可以得到更长的电池运行时间。联想仍然使用16:9长宽比的屏幕，但现在的IPS版本更加明亮，如果你想编辑图片，你可以得到一个100%sRGB的面板。与戴尔或惠普等其他入门级商务笔记本相比，增加的亮度也是一个优势。
如果你想买一台价格合理的办公笔记本电脑，并拥有一个体面的IPS屏幕、较长的电池运行时间和出色的键盘，ThinkPad E14 G3是一个不错的选择。
你可以在一些地方注意到低价，首先是一年的有限保修以及过时的端口选择，因为2021年的新设备都不应该配备USB 2.0。竞争对手要更轻巧一些，但ThinkPad E14 G3仍然得到我们的推荐。
