经济实惠的黑匣子

联想面向企业客户销售的价格更实惠的 ThinkPad 笔记本电脑是 ThinkPad L 系列。ThinkPad L14 Gen 4 AMD 是一款采用 AMD 技术的经济型机型，不过采用的是 Ryzen 7030。联想没有使用 Ryzen 7040 并不意味着 L14 是一款糟糕的笔记本电脑，但它会带来一些负面影响。

AMD Business Laptop / Notebook ThinkPad Windows Zen Ryzen (Zen)

在 ThinkPad 的世界里，ThinkPad L 系列标志着它进入了商务系列。这意味着它是面向商务用户的笔记本电脑系列，在成本方面进行了大量优化，并提供了较低的入门级价格。联想 THinkPad L14 Gen 4 AMD 就是今天要评测的设备，它是 14 英寸型号 ThinkPad L14 的第四代产品，这次采用的是 AMD Ryzen 7000。

由于设计与第三代 ThinkPad L14 相比没有变化，我们在联想 ThinkPad L14 Gen 3 的综合评测中介绍了连接选项、机箱/设计和输入设备等方面的情况。

显示屏：ThinkPad L 首次采用低功耗屏幕

ThinkPad L 系列的传统弱点是屏幕质量。作为经济型商务系列，屏幕通常是节省成本的领域之一。因此，这些笔记本电脑使用的显示屏往往亮度和色域覆盖率较低。就联想 ThinkPad L14 G4 AMD 而言，四款 14 英寸显示器中有三款符合这一特点。幸运的是，我们有了第四个选项。所有显示器仍然使用 16:9 宽高比，这使得 ThinkPad L14 成为最后几款使用这种宽高比的 ThinkPad 机型之一：

高清（1,366 x 768）、TN、220 cd/m²、45 % NTSC
全高清（1,920 x 1,080），IPS，250 cd/m²，45 % NTSC
全高清（1,920 x 1,080），IPS，300 cd/m²，45 % NTSC，多点触控
全高清（1,920 x 1,080），IPS，400 cd/m²，72 % NTSC，低功耗

我们已经从 T 系列的老款 ThinkPad 上了解到了这款产品所采用的低功耗屏幕，在此我们将首次对 ThinkPad L14 进行评测。显示屏亮度符合预期，整体亮度为 409 cd/m²。与其他经济型商用竞争产品相比，这是一个不错的亮度。但 AUD 面板的响应时间稍逊一筹，因为同类笔记本电脑的响应时间都很慢。对于办公用途来说，这并不是一个非常关键的问题，但用户会面临一些重影现象。

出厂时，屏幕略微偏冷，我们使用 X-Rite i1Pro 2 和 CalMan 进行了测量。在使用 X-Rite i1Profiler 校准后，我们将 deltaE 从 2.4 降到了 1.4--就色彩准确性而言，这是一个不错的值，但不是一个非常好的值。尤其是蓝色的准确度相当低。

由于基本上完全覆盖了 sRGB 色域，该面板的色域覆盖范围足以满足简单的照片编辑需求。DCI P3 和 AdobeRGB 的覆盖范围不足，说明这不是一款高端面板。

联想 ThinkPad L14 Gen 4 AMD 的屏幕亮度大约为 400 cd/m²，屏幕表面为磨砂材质，因此在户外也能使用。但应避免阳光直射。

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
32.7 ms ... rise ↗ and fall ↘ combined	↗ 15.4 ms rise
32.7 ms ... rise ↗ and fall ↘ combined	↘ 17.3 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. » 87 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
58.1 ms ... rise ↗ and fall ↘ combined	↗ 27.2 ms rise
58.1 ms ... rise ↗ and fall ↘ combined	↘ 30.9 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 94 % of all devices are better. This means that the measured response time is worse 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.

性能：只有 AMD Ryzen 7030U 而不是 Ryzen 7040U

联想在 ThinkPad L14 Gen 4 AMD 的规格表中列出了三种不同的 CPU。它们都属于 Ryzen 7030 系列/Barcelo Refresh： AMD Ryzen 3 Pro 7330U, Ryzen 5 Pro 7530U和 Ryzen 7 Pro 7730U.我们认为主要提供 Ryzen 5 和 Ryzen 7。

L14 G4 AMD 仅提供集成显卡，这意味着 Vega GPU 的确切类型取决于所选处理器。无论如何，ThinkPad L14 有两个 SO-DIMM 插槽，最多可支持 64 GB DDR4-3200 内存。在大容量存储方面，联想就没那么慷慨了，ThinkPad L14 G4 只有一个 M.2 2242 SSD 插槽。

测试条件

与联想ThinkPad的一贯做法一样，没有使用OEM软件来调节CPU性能和系统功耗。相反，联想使用的是 Windows 能源配置文件：

最佳性能：PL1 20.5 W / PL2 40 W
平衡：PL1 12 瓦 / PL2 15 瓦
最佳电池寿命PL1 10 瓦 / PL2 10 瓦

功率极限 1 (PL1) 描述的是 CPU 在持续负载下的功耗。而功耗限制 2 (PL2) 则是指短期提升性能时的最大功耗。

处理器

......（英文AMD Ryzen 5 Pro 7530U是 Ryzen 7000 系列的 "Barcelo Refresh "处理器。从该平台的代号就可以看出，它实际上并不是什么新技术，而只是去年 "Barcelo "平台的更新版--它本身已经是 Ryzen 5000 又名 "Cezanne "的更名。因此，这款六核芯片是两年前的处理器。时钟频率在 2 至 4.5 GHz 之间。名称中的 "Pro "表明这是一款具有商业功能的芯片，就像英特尔 vPro 一样。我们的处理器比较列表可用于与其他处理器进行更广泛的比较。

CPU 基准测试结果喜忧参半。在多核性能方面，联想 ThinkPad L14 G4 AMD 表现出色，因为它接近于惠普 EliteBook 645 G9及其 Ryzen 7 的性能相近。在持续负载下，多核性能有所下降，但仍高于英特尔的竞争对手。而在单核基准测试中，英特尔笔记本电脑的优势则恰恰相反。

在电池模式下，我们检测不到 CPU 有任何节流现象。

系统性能

系统性能基准测试的结果可以接受。不过，单通道内存拖慢了 ThinkPad 的运行速度，因此仍有改进的余地。在日常使用中，这一点影响不大。对于使用图形处理器的应用程序来说，它的影响最大。

大容量存储器

ThinkPad 笔记本电脑的存储空间是一块容量为 512 GB 的单面 M.2 2242 固态硬盘。固态硬盘由 Kioxia 制造，是 NVMe PCie 4.0 固态硬盘，不过由于 Ryzen 7030 平台过时，ThinkPad 只能在 PCIe 3.0 模式下使用。这意味着，虽然固态硬盘的速度并不慢，但还是损失了一些速度。与竞争对手相比，ThinkPad L14 第 4 代 AMD 表现出色，固态硬盘在负载情况下没有节流迹象。

GPU

迚ケ谿オ譎る俣 AMD Radeon RX Vega 7是一款过时的 GPU，已在 Ryzen 5000 系列中使用。在 ThinkPad L14 Gen 4 AMD 中，它还受到出厂单通道内存的限制，进一步限制了本已较低的性能。GPU 只能用于最简单的任务和基本游戏。如果安装第二个 SO-DIMM 模块，GPU 性能将得到改善，因为这意味着内存可以在更快的双通道模式下运行。

排放：L14 G4 的风扇比 L14 G3 更活跃

噪音

与前代产品 ThinkPad L14 G3 AMD 相比，ThinkPad L14 G4 AMD 的最大风扇噪音有所降低，目前最高可达 38.3 dB(a)。设备空闲时，风扇基本处于关闭状态。正面：风扇噪音不是特别高，这在戴尔Latitude 3440.

在 ThinkPad L14 G3 AMD 上，我们可以检测到一些线圈啸叫。

热量

说联想 ThinkPad L14 Gen 4 AMD "发热 "并不恰当。我们在键盘左上方的热点测得的最高温度为 46.3 摄氏度/115 华氏度。这个区域通常在高负荷使用时不会被频繁触碰。与笔记本空闲时的情况相比，掌托确实会发热，不过掌托温度始终保持在 30 摄氏度/86 华氏度以下。

压力测试可以用两个词来概括：无节流。即使在一小时后，CPU 功耗仍保持在 20 W。

能源管理：功耗低，电池寿命长

耗电量

与前代产品相比，至少在空转时耗电量较低。在负载情况下，情况则发生了逆转。总体而言，与其他经济型笔记本电脑相比，ThinkPad L14G4 AMD 的能效相当高，但与 ThinkPad T14 G3配备 Ryzen 7 Pro 6850U 的 ThinkPad T14 G3 的效率更高。

在最大功率下，ThinkPad L14G4 AMD 的耗电量为 61.3 W，对于 65 W 的充电器来说并不吃力。

结论联想 ThinkPad L14 G4 AMD 是一款物美价廉的工作利器

评测中：联想 ThinkPad L14 Gen 4 AMD，评测样品由联想提供：

背光键盘、IPS 屏幕，这些功能在联想经济型 ThinkPad L 系列中已经很久没有出现过了。现在，它们成为了可选项，低功耗屏幕也是如此，作为经济型系列的首款产品，联想 ThinkPad L14 第 4 代 AMD 可以对其进行测试。

这就解决了前代产品的一个核心批评点，即屏幕不好，至少对于这个特定的变体来说是这样。不过，低功耗屏幕也并非完美无缺，它所使用的面板响应时间较差，但与低亮度或低色域相比，这对于办公笔记本电脑来说并不是什么大问题。

除了显示屏之外，ThinkPad L14 4 代 AMD 与ThinkPad L14 第 3 代 AMD.机箱、输入设备和连接选项没有变化，这三个方面都非常好（输入设备、连接）到不错（机箱）。与更昂贵的机型相比，机箱在材质和稳定性方面略有下降。ThinkPad L14 G4 AMD 的电池续航时间非常不错。

一个明显的弱点是平台过时。Ryzen 7030U 虽然有了新名字，但基本上还是 Ryzen 5000。这意味着没有 USB4、DDR5 内存和 PCIe 4.0。单通道内存也影响了性能，但用户可以通过添加第二个内存模块轻松解决这个问题。一个小问题是，L14 G4 使用的是 M.2 2242 SSD 尺寸，限制了升级选择。另一方面，两个内存插槽使 ThinkPad L14 默认成为可升级性最强的 14 英寸 ThinkPad。

电池续航时间长，可升级：联想ThinkPad L14 G4 AMD是低价位笔记本电脑中的佼佼者。

总而言之，我们认为联想ThinkPad L14 G4 AMD是一款非常可靠的工作设备，价格也比较实惠。较低的价格意味着它没有采用一些较新的技术，机箱所用材料也不如其他 ThinkPad 那样优质，但它在办公室里的表现还是不错的。

另一种选择是戴尔Latitude 3440.这款基于英特尔的竞争对手拥有更高的单核性能，但如果用户选择戴尔，就必须放弃第二个 USB C 端口和 microSD 插槽。
