Windows Tiger Lake Thunderbolt Laptop / Notebook

我们已经评测过采用AMD处理器的联想ThinkPad L14 G2.我们喜欢它的设计、输入设备和其他功能。然而，我们批评了Wi-Fi速度、电池寿命和显示屏。

我们目前的审查设备被称为联想ThinkPad L14 G2-20X1003WGE。它的特点是英特尔酷睿i5-1135G7，8GB内存和256GB固态硬盘。这就是为什么，它应该适用于许多办公任务。它还提供了相当数量的GPU性能。

机箱和连接性 - 带有Thunderbolt 4的廉价ThinkPad

联想ThinkPad L14 G2的外壳是由坚固的塑料制成。制造质量处于高水平。任何地方都没有缝隙或缺口。显示器的开启角度为180度。显示屏的盖子相当坚硬。

与其他现代笔记本电脑相比，显示屏的边框看起来有点厚。ThinkPad L14 G2的重量约为1.7公斤，比我们为这次审查选择的所有其他竞争设备的重量都大。联想的笔记本电脑也比其他商务笔记本电脑更深、更厚一些。

两个USB-C端口中的一个可用于充电。另一个USB-C端口支持Thunderbolt 4，还集成了联想的对接端口。可选的是，L14 G2有一个智能卡读卡器和LTE，为此有相应的卡槽。

联想笔记本电脑中的microSD读卡器使用我们的参考级存储卡AV Pro V60，实现了73.91MB/s（写）和84.92MB/s（读）的体面数据传输率。

在用我们的参考级路由器Netgear Nighthawk AX12进行的Wi-Fi测试中，联想ThinkPad L14 G2在传输数据时只达到了907 MBit/s的平庸速度，在接收数据时则为662 MBit/s。

L14 G2的网络摄像头和目前大多数笔记本一样，只提供0.9MP的分辨率。因此，图像质量很差。一切看起来都很模糊，即使在良好的照明条件下，颜色也不清晰。

输入设备 - 带有背光键盘的联想笔记本电脑

ThinkPad L14 G2的键盘提供了一个清晰的启动点，适合长时间打字使用。键盘的布局是经过深思熟虑的。在这里，即使是方向键也不承担双重任务。两级背光允许用户在弱光环境下工作，并能均匀地照亮按键，没有任何眩光。

一个塑料ClickPad和一个TrackPoint作为鼠标的替代品。这两种输入设备都很适合导航鼠标指针。点击可以通过机械和触摸方式可靠地触发。在我们审查期间，联想笔记本的指纹传感器也能可靠地识别存储的指纹。

显示屏 - ThinkPad L14 G2的对比度良好

联想ThinkPad L14 G2有一个14英寸IPS屏幕，原始分辨率为1920x1080像素。由于最大亮度为294cd/m²，联想笔记本电脑在我们的对比表中占据了一个位置。90%的亮度分布是非常好的。

此外，没有 PWM闪烁，这意味着眼睛敏感的人不必担心任何问题。

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
36 ms ... rise ↗ and fall ↘ combined	↗ 21 ms rise
36 ms ... rise ↗ and fall ↘ combined	↘ 15 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 93 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
52 ms ... rise ↗ and fall ↘ combined	↗ 25 ms rise
52 ms ... rise ↗ and fall ↘ combined	↘ 27 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 87 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

根据我们的测量，该显示器提供了1400:1的良好对比度和0.21cd/m²的同样良好的黑值。然而，59.2%（sRGB）的色彩空间覆盖率是非常低的。

CalMAN分析表明，直接开箱显示的颜色相对准确。然而，色彩准确性可以通过校准来提高。我们的ICC配置文件的下载链接在包含所有显示测量值的盒子底部（这个盒子位于显示亮度分布的图形左侧）。

性能 - Tiger-Lake的CPU在负载下不会出现节流现象。

根据规格表，ThinkPad L14 G2配备了不同的CPU，其中有英特尔酷睿i7-1165G7是顶级选项。内存配置也不尽相同，而且没有配备专用GPU的型号--至少在欧洲是这样。在其他地方，L14 G2可以使用 GeForce MX450.我们的评测模型配备了一个英特尔酷睿i5-1135G7，8GB内存和256GB固态硬盘，因此很适合各种办公应用。

处理器

该英特尔酷睿i5-1135G7是一个4核/8线程的CPU。时钟频率在2.4和4.2GHz之间，据此，最大性能取决于冷却系统以及TDP。在这里，联想配置的短期值为60W（PLA2），长期值为28W（PL1）。

在我们的Cinebench R15压力测试中，ThinkPad L14 G2成功地将其性能保持在一个较高的水平。

在某些基准测试中，联想的笔记本电脑实现了高水平的多核性能，只有拥有AMD Ryzen 7 5850 Pro的竞争对手能够击败它。单核性能足以在我们的比较图表中占据一个位置。Geekbench的低分是引人注目的，即使在第二次基准测试运行后也没有明显改善。

在电池电量方面，启用电池效率模式时，Cinebench R15的多核得分下降到248分。在性能模式下，即使拔掉插头也能达到872分。

图形卡

这款 Intel Iris Xe Graphics G7 80EUs负责图像渲染。iGPU受益于在双通道模式下运行的快速RAM，而这里的情况并非如此。

由于在我们的评测设备中，RAM以单通道模式运行，因此在3DMark基准测试中的性能低于其他配备该GPU的笔记本。通过安装第二个RAM模块可以提高性能。

在电池供电的情况下，3DMark 11的得分在性能模式下为3787分，在效率模式下为2494分。你可以了解iGPU与其他图形卡的比较，在我们的 GPU基准测试页面上了解iGPU与其他显卡的比较。

Emissions & Energy - Lenovo ThinkPad with mediocre battery life

系统噪音

在日常使用中，当使用办公应用程序和浏览互联网时，ThinkPad L14 G2的风扇是听不到的，这导致了安静的操作。即使在我们的压力测试中，主动冷却系统也只是在很晚的时候才启动，在风扇稳定旋转的情况下，最大声压级为41.1 dB(A)。

温度

根据我们的测量，ThinkPad L14 G2的表面温度在非常大的负荷下达到51.3°C（124.34°F）。最热的地方在右上角；腕部休息区总是感觉相对凉爽。

在我们的长期压力测试中，L14 G2内部的温度很快就达到了100℃（212°F）。冷却系统最终能够将其降低到93℃（199.4℉）。时钟频率在短时间内明显低于基本频率，但随后稳定在3.8GHz左右。尽管负载很重，系统仍然可以使用。由于冷却解决方案工作良好，而且在我们的压力测试方案中看到的负载在实践中极不可能发生，我们预计在日常使用中不会看到任何热节流。

联想笔记本电脑的扬声器很安静，听起来很尖锐。因此，在非常安静的环境中偶尔播放媒体内容是可能的。不过，我们建议使用耳机或外部扬声器。

能源消耗

闲置时，我们测得的耗电量为7W。在压力测试中，能耗峰值为59W。因此，耗电量与其他具有这种硬件的笔记本相当。

附带的65瓦电源适配器即使在负载情况下，为联想笔记本电脑提供足够的电力应该没有问题。

结论 - 好的笔记本，有一些改进的空间

对联想ThinkPad L14 G2的评论。评测设备由campuspoint提供。

联想的ThinkPad过去和现在都是不错的办公笔记本电脑。L系列是如此，因此ThinkPad L14 G2也是如此。性能处于良好水平，系统和应用程序都感觉反应灵敏。升级内存的选项弥补了相对较低的图形性能。

联想ThinkPad L14 G2是一个很好的日常伴侣，即使使用的是英特尔CPU，但更长的电池运行时间也是非常值得赞赏的。

然而，在一些领域，竞争对手正在变得更好。最重要的是，这里必须提到重量和尺寸。在直接比较中，L14 G2看起来比其他14英寸笔记本更大更重。显示屏和电池寿命在未来肯定能得到改善。

总而言之，ThinkPad L14 G2是值得购买的。与竞争对手如申克威盛14，以及华硕ExpertBook B1 B1400或 Acer Swift 5 SF514不过，也有很好的替代品可以选择。

价格和可用性

采用英特尔CPU的联想ThinkPad L14 G2目前在亚马逊上销售。.
