AMD Business Laptop / Notebook Ryzen (Zen) ThinkPad Windows

ThinkPad L 系列以合理的价格提供入门级和中端商务笔记本。这款 15.6 英寸笔记本最便宜的型号约为 900 美元。联想同时销售采用 AMD 和英特尔内核的机型，而这款机型采用的是 AMD 内核。 ThinkPad L14 Gen 4是我们刚刚评估过的一款 14 英寸机型。

宏碁 Aspire Vero AV15-53P、申克 VIA 15 Pro M22, 惠普 ProBook 445 G10, 富士通 LifeBook E5412A和戴尔Latitude 3440都是竞争对手。后三款笔记本电脑各自的 15.6 英寸姊妹版更具有这种相似性。

外壳 - L15 的技术封装在塑料外壳中

该机箱采用黑色塑料制成，设计简洁实用。更高级的 ThinkPad 系列才采用更精致的外壳材料。机盖背面和掌托上都醒目地印有标志性的 "ThinkPad "字样，表面光滑哑光。值得注意的是，该机没有维护挡板；不过，取下底部外壳后，可以接触到电池（用螺丝固定，而非胶粘）和其他内部元件。

该设备在加工方面没有明显缺陷，缝隙尺寸正确。虽然底座的扭转幅度稍大，但还是希望能有更高的刚性。盖子保持在合理的范围内。向盖子背面施压不会导致图像变化，紧固的铰链能牢牢地将盖子固定在位置上。最大开启角度为 180 度，可单手开启。

在同类产品中，ThinkPad 是最重的笔记本电脑，重约 4.188 磅。就尺寸而言，测试中的 15.6 英寸设备并无太多相似之处。当然，14 英寸的竞争对手要小巧和轻便得多。

连接性 - ThinkPad 没有配备 Thunderbolt

该笔记本配备了两个 USB-A 端口（USB 3.2 Gen 1）和两个 USB-C 端口（USB 3.2 Gen 2）。值得注意的是，USB-C 端口支持 Power Delivery 和 DisplayPort 功能。结合 HDMI 插槽，该笔记本电脑拥有多达三个视频输出端口。此外，它还配备了一个组合音频插座、千兆以太网和一个可选的智能卡读卡器，使其连接选项更加完善。

交流

在最佳条件下，例如附近没有 WiFi 设备，笔记本电脑和服务器 PC 之间的距离很短，就能实现非常好的 WiFi 数据传输速率。L15 配备了 WiFi 6E 芯片（联发科 MT7922）。在有线连接方面，它采用了 Realtek 的控制器（RTL8168/8111；1 GBit/s）。

除 WiFi 外，由于配备了相应的调制解调器（Quectel EM05-G；CAT 4，最大下载速率 150 MBit/s，上传速率 50 MBit/s），还可通过 LTE 网络建立无线连接。SIM 卡读卡器（nano-SIM）位于笔记本电脑背面，还支持 eSIM 卡

网络摄像头

在质量方面，网络摄像头（210 万像素 + 红外，最大像素 1,920 x 1,080）的表现符合标准。不过，色彩偏差约为 12（目标值为 DeltaE < 3），略高于预期。值得肯定的是，该摄像头配有一个机械盖，增强了隐私性和安全性。

ColorChecker Lenovo ThinkPad L15 Gen 4 21H70021GE: 12.11 ∆E min: 2.01 - max: 18.24 ∆E

安全

该笔记本电脑通过指纹识别、Windows Hello 或智能卡身份验证提供访问安全性。此外，它还配备了可信平台模块（2.0），可增强安全性。在物理安全方面，该设备可使用电缆锁进行保护。

配件

除了标准文件（保修信息、快速入门海报）外，TP 不包括其他附件。

维护

拧松下面的螺丝后，可以用扁平刮刀取下底板。这样就可以接触到各种组件，包括固态硬盘（PCIe 3 插槽中的 PCIe 4 固态硬盘，M.2-2242）、WLAN 模块、LTE 调制解调器、内存库、电池、扬声器、风扇和 BIOS 电池。

保修

联想为 ThinkPad 在美国境内提供为期一年的保修服务。

输入设备 - 键盘的稳定性有待提高

键盘

联想为 ThinkPad 配备了背光（两级）chiclet 键盘，其中包括数字键盘。光滑的凹面按键键程短而清晰。虽然按键阻力尚可接受，但有些用户可能更喜欢清脆的手感。值得注意的是，键盘在键入时会有轻微的反弹。一个不便之处是 FN 键和左 CTRL 键的位置对调，需要用户调整练习手部动作。尽管如此，联想还是提供了一个非常出色的键盘，非常适合日常使用。

触摸板

点击垫的尺寸约为 4.52 x 2.20 英寸，是鼠标的主要替代品，具有较短的行程和清晰的压力点。轨迹点也可用于更精确地控制鼠标指针。与之配套的三个运行流畅的鼠标按键提供了一个清晰的压力点。

显示屏 - FHD 面板，色彩空间覆盖率低

联想为 ThinkPad L15 G4 配备了 16:9 格式的 15.6 英寸哑光、视角稳定的显示屏（1920 x 1080 像素）。值得注意的是，显示屏没有 PWM 闪烁，对比度也相当高。亮度略低于目标值（大于 300 cd/m²）。此外，ThinkPad 还提供亮度稍高的全高清触摸屏。没有其他显示屏可供选择。

* ... smaller is better

显示器开箱即可显示可接受的色彩，但偏差约为 6.2，未达到目标（DeltaE < 3）。

该面板无法再现 AdobeRGB（43%）、sRGB（63%）和 DCI-P3 （42%）色彩空间。因此，它可能不适合对色彩保真度要求较高的应用场景，因为一些竞争对手在这方面提供了更好的性能。

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
19.7 ms ... rise ↗ and fall ↘ combined	↗ 10.7 ms rise
19.7 ms ... rise ↗ and fall ↘ combined	↘ 9 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. » 39 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
24.4 ms ... rise ↗ and fall ↘ combined	↗ 11.9 ms rise
24.4 ms ... rise ↗ and fall ↘ combined	↘ 12.5 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 0.165 (minimum) to 636 (maximum) ms. » 31 % of all devices are better. This means that the measured response time is better than the average of all tested devices (32.9 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 8743 (minimum: 5 - maximum: 343500) Hz was measured.

视角稳定的 IPS 面板允许从任何位置进行阅读。此外，只要阳光不太强烈，在户外也可以阅读屏幕。

性能 - Ryzen 火力全开

在 ThinkPad L15 G4 系列中，联想提供了搭载 AMD APU（Ryzen 7000）和英特尔 CPU（Raptor Lake）的机型。在本次评测中，我们将重点介绍基于 AMD 的机型。在测试期间，AMD 机型的价格从 900 美元到 1300 美元不等。

测试条件

联想没有使用自己的能耗配置文件，而是采用了 Windows 配置文件，称为能耗状态（见表）。根据所选状态的不同，所提供的性能水平也不同。对于基准测试和运行时负载，使用了 "最佳性能 "配置文件，而对于其他运行时测试，则使用了 "平衡 "配置文件。

	最佳性能	平衡	最佳节能
功率限制 1 (HWInfo)	31 瓦	25 瓦	15 瓦
功率限制 2 (HWInfo)	40 瓦	30 瓦	20 瓦

处理器

产品 Ryzen 7 PRO 7730U APURyzen 7 PRO 7730U APU 属于 Barcelo 系列，基于 Zen 3 架构，拥有 8 个 CPU 内核，共 16 个线程，单核心最高主频可达 4.55 GHz。正如在 CB15 循环中观察到的那样，在持续的多线程负载下，CPU 始终保持较高的 Turbo 时钟。

虽然性能受使用中的能源配置文件影响，但不同配置文件之间的差异并不大。

基准测试结果与非 "PRO "版本的 Ryzen 7 7730U APU 相比，表明在 "最佳性能 "配置文件下，目前的 APU 值处于平均水平。PRO "表示支持AMD PRO 技术。技术，包括一系列专为商业用途定制的安全功能。

	最佳性能（网络/电池）	平衡	最佳节能
CB 15（多线程）	1.756 pts/1.029 pts	1.543 pts	1.385 pts
CB 15（单线程）	230 分/96 分	226 分	209 分

系统性能

流畅的操作系统经过优化，适用于办公和互联网应用，以及低设置下的节俭型游戏。由于内存（16 GB，DDR4-3200）仅在单通道模式下运行，部分计算能力仍未发挥出来。安装第二个内存模块可以弥补这一缺陷，激活双通道模式以提高性能。

存储设备

系统硬盘是来自 SK Hynix 的 512 GB SSD（PCIe 4，M.2-2242），整体数据传输率良好。由于安装在 PCIe 3 插槽中，它未能充分发挥潜力。值得肯定的是，它没有出现热引起的节流现象。需要强调的是，它只兼容 M.2-2242 格式的固态硬盘，不兼容更常见的 M.2-2280 型号。遗憾的是，L15 没有为额外的固态硬盘提供空间。

系统硬盘是 PCIe 固态硬盘，L15 只能容纳 M.2-2242 格式的固态硬盘，而不是更常见的 M.2-2280 型号。

图形卡

集成的 Vega 8iGPU 在 AMD 目前的产品阵容中处于中端位置，拥有 512 个着色器，支持 DirectX 12，最高时钟频率为 2,000 MHz。令人印象深刻的是，后者可以永久保持，这在Witcher 3 测试中得到了证明。由于工作内存在单通道模式下运行，基准测试结果远远低于平均水平。如果安装第二个内存模块，激活双通道模式（见图），就能大幅提升性能。

游戏性能

虽然内置 APU 的运算能力可以满足许多低设置下的低要求游戏，但必须指出的是，ThinkPad 并不是作为游戏笔记本设计的。所观察到的相对较低的帧速率可归因于在单通道模式下运行的内存。值得注意的是，如果安装第二个内存模块，从而激活双通道模式（见图），性能将得到明显改善。

系统噪音

ThinkPad 在整个负载范围内都能保持极低的噪音水平。风扇经常保持静止或低速运转。在 "最佳性能 "能耗模式下，满载时的最大声压级达到 32.7 dB(A)--许多笔记本电脑在低负载时甚至达不到这个值。

可惜的是：当大量访问固态硬盘时，机壳内会传出电子溅射声。

压力测试

压力测试包括 Prime95 和 Furmark 的连续运行，是测试系统在满负荷情况下稳定性的极端场景。测试开始时，CPU 的时钟频率为 3.4 至 3.6 GHz，随着测试的进行，时钟频率逐渐降至 3 至 3.1 GHz。与此同时，GPU 的时钟频率在短时间内从 2 GHz 降至 1.4 GHz，并保持在这一较低水平。

电池寿命

根据数据表，联想为 ThinkPad 提供了三种电池选择（46.5 Wh、57 Wh 和 63 Wh），本次测试使用的是中间一种。因此，这款 15.6 英寸平板电脑的实际运行时间非常出色，达到了 11:56 小时（WiFi；通过脚本浏览网站）和 9:29 小时（视频；短片 Big Buck Bunny，H.264 编码，FHD）。

评语 - 可靠的商务笔记本

与 Ryzen 7 PRO 7730U和 16GB 内存（单通道模式）的组合，可轻松应对办公、互联网应用和节俭型游戏。我们建议安装第二个内存模块，以充分释放 APU 的潜力，尤其是图形性能。

联想推出的 ThinkPad L15 Gen 4（AMD）是一款性能全面的中端商务笔记本电脑，但也存在一些小缺点。

其紧凑的设计、适中的重量（约 4.18 磅）和出色的运行时间使 L15 成为一款移动性很强的笔记本电脑。两个用于供电的 USB-C 端口（USB 3.2 Gen 2）和与现有工作站设置的无缝集成是其显著特点。此外，低辐射值和内置的 LTE 调制解调器也起到了积极作用。

不过，内置的 FHD 屏幕（IPS，15.6 英寸）在色彩空间覆盖方面存在不足，亮度仍低于目标值（大于 300 cd/m²）。尽管存在这些缺点，但该显示屏仍拥有出色的对比度和哑光表面。

作为 L15 的替代品，Acer Aspire Vero AV15 。它拥有更亮、色彩更丰富（sRGB）的 FHD 显示屏、两个 Thunderbolt 4 端口和一个 QHD 网络摄像头。但它也有不足之处，比如没有千兆以太网插槽和存储卡读卡器。此外，内存是板载的，这意味着无法更换或扩展。

价格和供应情况

联想 ThinkPad L15 Gen 4（AMD）在亚马逊的售价为 1,300 美元。
