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。

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。

DPC 延迟
在我们的 LatencyMon 测试中,联想 ThinkPad L14 G4 AMD 出现了一些 DPC 延迟问题,显然是网络驱动程序造成的。要运行实时视频和音频,应禁用网络模块。当然,这种现状可以通过驱动程序和固件更新来修正。

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。

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。
(+) The maximum temperature on the upper side is 39 °C / 102 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.

(+) In idle usage, the average temperature for the upper side is 25.1 °C / 77 F, compared to the device average of 29.5 °C / 85 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 33.3 °C / 92 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 30.3 °C / 86.5 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (-2.6 °C / -4.6 F).

结论联想 ThinkPad L14 G4 AMD 是一款物美价廉的工作利器
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。
