联想ThinkPad E14 G4 AMD笔记本电脑评论：经济实惠，没有大的弱点

Name: Lenovo ThinkPad E14 G4 21EB0041GE
Brand: Lenovo

全能型选手？

ThinkPad E14 G4 AMD以较低的价格提供了非常高的性能，几乎在每一个方面都很耀眼：坚固、具有1.8毫米行程的伟大键盘、低排放、一个内存插槽以及两个固态硬盘插槽和一个RJ45端口。最重要的是，它拥有相当明亮的哑光IPS显示屏。从总分中扣除的分数来自小的批评点。

虽然联想之前推出了更明亮的显示选项，包括100% sRGB，但在的直接前辈在ThinkPad E14的直接前身中，第四代商务笔记本的进步主要围绕着性能，这甚至比更昂贵的T系列略高，而且你还得到了一个更好的键盘。除了良好的硬件外，这两点都是非常具有决定性的，这取决于笔记本电脑的使用方式。与其他流行的ThinkPad系列的进一步差异将在本评论中揭示。

只有处理器选项是新的，但这些也只是AMD的Zen 2架构的刷新（Barcelo-U），在E14 Gen 3中已经发现。我们的测试实验室仔细研究了885欧元（约950美元）的 "21EB0041GE "型号，其八核的AMD Ryzen 7 5825U16GB DDR4内存（可扩展），512GB PCIe 3.0 SSD和全高清IPS显示屏（宣传的峰值亮度为300 cd/m²）。作为校园版，这款移动商务笔记本的价格并不便宜，为869欧元（约合935美元），但六核CPU和无操作系统也可能是649欧元（约合700美元）。

外壳：坚固的黑色ThinkPad E14 G4

联想ThinkPad典型的黑色外壳自第二代以来一直没有改变。第2代、但也有银色的选择。低价反映了材料的选择，即塑料（掌托和显示屏边缘）和黑色阳极氧化铝（盖子和底部）的组合。尽管如此，稳定性还是非常好。底部装置可以抵御扭转压力，盖子可以抵御对背部的目标压力。铰链也令人愉快地牢固，但用一只手打开是不可能的。

光滑的表面看起来并不像ThinkPad T14那样高质量。 ThinkPad T14或 T14s而且非常容易沾染指纹。总的来说，这个箱子给人留下了良好的印象，尤其是考虑到价格低廉。

ThinkPad E14是我们的对比组中最重的14英寸产品，重量为1.6公斤，但比大多数对手要薄。虽然屏幕的侧边非常窄，但这并不适用于顶部和底部的边缘。因此，该设备的构建深度也明显大于对比设备的深度。

设备：千兆位网络，1,080p凸轮和两个SSD插槽

两年来，在端口方面也没有什么变化。过时的USB-A 2.0和HDMI 1.4b仍然在船上。至少有千兆位网络（可选）和一个带有DisplayPort 1.2和充电功能的USB-C 3.2 Gen 1。然而，充电时如果没有适配器或对接方案，就不能使用USB-C外围设备。

沟通

几乎使用了与前代ThinkPad相同的Realtek WiFi 6适配器，这也反映在平庸的WLAN速度上，最高为~1 Gbps。一个英特尔AX201或AX211，如在戴尔Latitude 14 5420或惠普 ProBook 440 G9显著更快，与两年前的ThinkPad E14 G2的英特尔AX200相似。不提供WWAN型号。

网络摄像头

一个小但真正的升级是内置的1080p网络摄像头，与前代产品的720p版本相比。它更清晰，噪音更小，但仍然只能用于最简单的视频通话。包括一个物理快门（ThinkShutter），我们的机型还有一个用于Windows Hello的红外摄像头。

ColorChecker Lenovo ThinkPad E14 G4 21EB0041GE: 14.06 ∆E min: 2.01 - max: 23.98 ∆E

安全问题

在安全方面，有红外摄像头、物理摄像头光圈、TPM 2.0、Kensington锁和集成在电源按钮上的可选指纹扫描仪，它们在我们的测试设备上快速而完美地工作。在软件方面，与T系列的ThinkPad相比，你不得不放弃Mirametrix Glance和人类存在检测。

辅料

盒子里只包括65W的USB-C电源。值得称赞的是，包装材料几乎没有使用塑料。

维护

在打开设备之前，应在BIOS中停用内部电池。松开七颗十字螺丝后，机箱托盘和它的夹子可以用铲子相对容易地取出。之后，你可以看到已安装的M.2 2242固态硬盘、一个内存插槽（已占用）、WLAN插槽以及一个用于较长M.2 2280固态硬盘的额外插槽。57Wh的电池只用螺丝固定，风扇可以清洗。

担保

在美国，联想提供12个月的现场支持保修，可以升级到2年、3年、4年或5年，附加费用也相应提高。更多的综合保修服务可以通过Premier Onsite Support 和Premier Support Plus的形式提供，也有1到5年的计划，价格也在增加。总的来说，附加费用从最低的+25.00美元（Premier Onsite Support，1年）到最高的+381.85美元（Premier Support Plus，5年）。详细的概述可以在这里看到https://www.lenovo.com/us/en/pb/index.html?mainCode=21EB0022US&guid=7b27957b-19f0-40d8-8ebd-79baabc42774#step=1.

当然，这些价格在其他国家可能有所不同，所以有兴趣的买家应在购买前仔细检查。

输入设备：在ThinkPad E14上有1.8毫米的行程，仍然很好。

键盘

如果你正在寻找紧凑型商务笔记本电脑中的最佳键盘，你很难避免联想ThinkPad E14。所有较新的ThinkPad的键程为1.5毫米，而E14 G4的键程为1.8毫米，这使得许多用户的打字体验更加愉快，反馈更加丰富。

全宽的6排键盘，其凹陷的16 x 16毫米的按键是防溢出的，所有重要的按键都是专用的。两段式背光键盘在有针对性的压力下根本不会屈服。如果你直接从联想订购，你必须单独选择背光。

触摸板和TrackPoint

10 x 5.6厘米的触摸板比其他一些ThinkPads上的触摸板要小一点。然而，它的Mylar表面提供了一个平滑的滑行体验，但感觉不像玻璃。触摸板。集成的点击按钮提供了丰富的反馈和中等行程。我们非常喜欢TrackPoint按键，特别是因为它们不是完全平坦的，与较新的ThinkPad上的按键相比。

显示：足够的亮度，可选择100%的sRGB

我们的测试设备使用标准的IPS显示屏，分辨率为全高清（1920x1080），指定亮度为300cd/m²。该面板的名称与直接的前辈甚至还更亮一些，测量值为330cd/m²。

此外，ThinkPad E14还提供了一个100% sRGB的显示选项，用于在sRGB范围内进行更强烈的色彩和媒体编辑。另一方面，不推荐提供的TN选项：

1.920x1.080，TN，250 cd/m²，16:9，500:1，45% NTSC
1.920x1.080，IPS，300 cd/m²，16:9，800:1，45% NTSC
1.920x1.080，IPS，300 cd/m²，16：9，1200：1，100% sRGB

实测对比度为1,035:1，略高于平均水平，而主观的画面印象也是平均到良好。响应时间不算太慢，所以重影现象几乎不明显。也没有发现PWM闪烁。然而，黑暗背景上的清晰光晕有时会让人有点烦躁。

由于sRGB色彩空间的覆盖率仅有不到60%，需要精确色彩的图像编辑是不可能的。在这种情况下，你必须选择ThinkPad E14的100% sRGB选项，只要你能找到上市的这种型号。

灰度等级在出厂前就已经很准确了，但在颜色方面情况就不同了，即使经过校准，几乎所有的颜色都与目标值<3有很大的偏差。至少没有发现偏色。我们用X-Rite i1Pro 2校准的色彩配置文件可以在这里下载https://notebookcheck.com/uploads/tx_nbc2/LEN40A9_02.icm.

Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White
20.3 ms ... rise ↗ and fall ↘ combined	↗ 11 ms rise
20.3 ms ... rise ↗ and fall ↘ combined	↘ 9.3 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 42 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
26.1 ms ... rise ↗ and fall ↘ combined	↗ 12.9 ms rise
26.1 ms ... rise ↗ and fall ↘ combined	↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 32 % of all devices are better. This means that the measured response time is better than the average of all tested devices (32.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8702 (minimum: 5 - maximum: 343500) Hz was measured.

额外的亮度与哑光面板相结合，对户外使用很有帮助，但仍建议在阴凉处使用。

性能：尽管Barcelo U，ThinkPad E14提供了很多。

我们评测的是ThinkPad E14第四代，配备八核心的AMD Ryzen 7 5825U、它与六核Ryzen 5 5625U一起提供。 Ryzen 5 5625U和四核 Ryzen 3 5425UCPU。这款 RX Vega 8被用作图形单元。由于底层的Zen 2架构，RDNA 2 GPU和USB 4必须被省略。

16GB DDR4-3200内存（8GB焊接+8GB插槽）可以扩展到40GB，尽管16GB仍将继续以双通道模式运行。在我们的SKU上，512GB PCIe 3.0固态硬盘采用较短的M.2 2242格式。

总的来说，所提供的性能对于纯粹的办公电脑来说是过剩的，所以多媒体使用，如FHD视频编辑或音乐制作，是一个明显的可能性，但这里应该选择100%sRGB的面板。英特尔机型最高配备酷睿i7 1260P和Thunderbolt 4的英特尔型号也是可用的。

测试条件

联想并没有在其ThinkPad笔记本电脑上提供自己的性能配置程序。相反，这些程序被内置到Windows的电源设置中。有三个配置文件影响性能、电池寿命和排放：

最佳节能：11W
平衡：25W（PL2） > 20W
最佳性能：30W

我们在最佳性能 模式下进行了所有的性能测试，但WiFi和视频电池寿命除外，它们是在平衡模式下测量的。

处理器

AMDRyzen 7 5825U 有8个核心，16个线程，属于Barcelo U刷新，因此仍然基于Zen 2架构。与Ryzen 7 PRO 6850U 相比，ThinkPad T14 G3 的多核性能较高，如下面的Cinebench R15图表所示，令人高兴。这主要是由于ThinkPad E14的TDP较高，为31W，而T14则从30W迅速降至25W。E14 G4的性能在电池模式下也保持稳定。

竞争对手也明显被打败了，包括上一代产品，代表作是 ThinkPad E15 G3为代表，配备了八核 Ryzen 7 5700U，在我们的总体评级中，它的表现整整超过了18%。然而，在单核性能方面，惠普ProBook 440 G9的单核性能超过了上一代产品。惠普ProBook 440 G9显著更快，这要归功于其英特尔CPU 酷睿i7 1255U.

排放：在ThinkPad E14 G4 AMD中，风扇基本无声。

噪声

ThinkPad E14 G4的风扇在闲置、浏览网页或执行办公任务时始终保持沉默。只有3D应用程序和CPU密集型任务才会使风扇活跃起来，尽管它的平均音量为34.5 dB(A)，但不会太大，尤其是没有高频声音发出。

除了ProBook 440 G9 ，竞争对手在中高负荷下的风扇行为明显更响亮。在E14中没有检测到电子噪音，如线圈啸叫。

在综合压力测试（Prime95 + FurMark）中，CPU保持在2.7GHz的基础时钟以上。有趣的是，CPU和GPU的时钟在大约30分钟后明显增加，GPU的时钟从1.1GHz增加到1.7GHz以上。

刚超过80℃的温度属于良好范围。在纯粹的GPU压力下，iGPU在一小时后保持2GHz的全时钟。

ThinkPad E14的2个2 W立体声扬声器有一丝低音，而高音是平衡的，中音是线性的，但仍然太安静，只有68 dB(A)，以便能够真正享受音乐。

观看视频和视频通话是可能的，没有问题。对于其他一切，我们建议通过3.5毫米插孔或蓝牙外接耳机。

这款 ProBook 440 G9在这项测试中甚至没有坚持6个小时，而采用英特尔CPU的两个竞争对手，即 Acer Swift 5和戴尔的 Latitude 14 5420，持续时间约为13小时。

对ThinkPad E14 AMD的评价：如果配置正确，是负担得起的全能型产品

一方面，联想ThinkPad E14 G4 AMD是一款优秀的移动工作设备，拥有出色的键盘，低排放，八核CPU带来的非常高的性能水平，可扩展的内存，RJ45和一个FHD网络摄像头。相当明亮的显示屏和坚固的外壳也是加分项。

然而，联想在第四代ThinkPad E系列中连续第三次使用相同的设计，这只会在未来一代中发生变化。一般来说，这个更新周期完全没有问题，并提供了良好的键盘的优势，但USB 2.0标准、相当沉重和笨重的外壳与16:9的显示屏，以及缺乏内部升级的可能性，对于本来是高质量和廉价的设备的14英寸商务笔记本来说，留下了一些苦涩的回味。

ThinkPad E14 G4 AMD提供了足够的马力，即使是简单的多媒体工作，特别是如果你能找到一个100% sRGB的型号。但对于办公室工作来说，不一定非要用Ryzen 7，这对价格有积极影响。

总而言之，我们可以轻松地推荐直接的前辈只要你找到一个相应的更便宜的报价。一个有趣的选择是戴尔Latitude 14 5420尽管它有一个糟糕的触摸板，而且明显较低的CPU性能仅限于纯粹的办公工作和网上冲浪。惠普ProBook 440 G9的显示屏惠普ProBook 440 G9的显示屏太暗，而1公斤重的 Acer Swift 5 SF514有一个光亮的触摸屏，但如果你能适应键盘并愿意多花200美元左右，它是一个非常好的选择。

同样有趣的是 ThinkPad L14 G3 AMD它的价格略高，基本上提供了相同的功能，但提供了更长的电池寿命，长达4小时。然而，它的扁平TrackPoint键只提供1.5毫米的键程。它还有点厚，但有两个内存插槽和一个400 cd/m²的明亮的低功耗显示器选项。
