联想ThinkPad T14s G4评测：采用 AMD Zen4 的商务笔记本电脑更出色

AMD 和 IPS 战胜英特尔和 OLED。 我们已经评测过目前配备英特尔处理器和高分辨率 OLED 面板的 ThinkPad T14s G4，现在我们又迎来了配备 Ryzen 7 7840U 和低功耗 IPS 显示屏的 AMD 机型。除了性能大幅提升外，良好的电池续航能力也尤其令人印象深刻。
AMD Business Laptop / Notebook ThinkPad Ultrabook Windows

ThinkPad T14s G4 是一款高端商务笔记本，仅次于ThinkPad X1 Carbon超越。与 X1 Carbon 不同的是，联想为 T14s G4 提供了英特尔和 AMD 两种处理器。我们 已经评测过英特尔但该设备在多核性能和电池续航时间方面未能赢得我们的青睐。现在我们来看看 T14s G4 AMD 版，它配备了 Ryzen 7 7840U和 400 cd/m² 的哑光低功耗全高清面板的 AMD T14s G4。

我们的测试设备是 ThinkPad T14s G4 21F8002TGE，它的配置非常出色，因为除了上述 Ryzen 7 处理器外，它还配备了Radeon 780M iGPU32 GB LPDDR5 6400 内存、1 TB SSD、LTE 调制解调器和 400 cd/m² 的低功耗显示屏。

我们对 HP EliteBook 845 G10(同样采用 Ryzen 7 7840U 和低功耗全高清面板）也给我们留下了非常好的印象--它是 T14s G4 最大的竞争对手，因此我们很想看看 AMD ThinkPad 在直接对比中的表现如何。

案例与设备

从外观上看，ThinkPad T14s G4 的 AMD 版可以通过掌托上不同的贴纸辨认出来，除此之外与英特尔版没有任何区别。碳纤维和镁铝合金材质的机身非常稳定，但黑色表面对灰尘也很敏感。另一方面，ThinkPad T14s G4 可选配风暴灰，在这方面的敏感度较低。惠普的 EliteBook 845 G10 采用银色机身，在这方面更具优势，但两款机型在质量方面差别不大。

端口方面存在一些差异，因为只有英特尔机型提供 Thunderbolt 支持。但 AMD 机型则完全不用担心，它有两个快速 USB-C 4.0 端口，而且与英特尔机型一样，还安装了 500 万像素摄像头。

输入设备 - 1.5 毫米行程

我们已经多次报道过当前的 ThinkPad 键盘，目前仍在使用行程为 1.5 毫米的型号。T14s G4 仍是 ThinkPad 系列中打字体验最好的产品之一，手感也比最近评测的ThinkPad P1 G6进行直接比较。与主要竞争对手相比 惠普 EliteBook 845 G10相比，二者在质量上并无太大差别。ThinkPad 键盘以前的优势已不复存在，用户可以在这两款笔记本上顺利输入长文本。白色背光（两个亮度级别）不能通过传感器激活，不过联想已经在（更便宜的）消费者机型上提供了这种功能，如 Yoga Slim 7 14 G8.ClickPad 和 TrackPoint 功能正常，指针控制也没有问题。

只有极小的光晕（此处显示的是强化后的光晕）

我们的 ThinkPad T14s G4 测试设备配备了著名的低功耗 IPS 显示屏，联想的 14 英寸商用笔记本电脑使用这种显示屏已有相当长的时间。我们过去曾多次看到联想使用不同的面板供应商，因此数值会有所不同，但所有型号都应达到指定的 400 cd/m²。我们的面板来自 LG 飞利浦，主观画质不错，虽然无法与高分辨率的 OLED 屏幕媲美，但对于商务设备来说绝对是个不错的选择。所有内容都很清晰，色彩浓郁，尽管表面是磨砂的，但即使是明亮的内容也不会显得有颗粒感。

我们的设备在亮度方面表现非常出色，平均亮度超过 450 cd/m²。同时，0.24 cd/m² 的黑色值对于 IPS 面板来说非常低，因此最大对比度超过 1,800:1。响应时间不是最快的，但也不令人讨厌，全亮度下几乎看不到光晕。在测量值方面，ThinkPad 的得分略高于配备低功耗显示屏的惠普 EliteBook 845 G10。

我们使用专业的 CalMAN 软件（X-Rite i1 Pro 2）对面板进行了测量。开箱即显示出明显的偏蓝和过冷的色温。色彩中还存在一些异常值。我们自己进行的校准控制了所有这些问题，灰度和色彩都低于重要的 DeltaE-2000 临界值 3。校准后，最大亮度降低了约 40 cd/m²，但由于图像质量显著提高，我们仍然推荐使用校准。我们的校准配置文件可在上面免费下载，但您应确保安装了相同的面板（例如，可通过 HWiNFO 确定）。

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
25.1 ms ... rise ↗ and fall ↘ combined↗ 12 ms rise
↘ 13.1 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 0.1 (minimum) to 240 (maximum) ms. » 55 % 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
41.6 ms ... rise ↗ and fall ↘ combined↗ 18.7 ms rise

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. » 62 % 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 17903 (minimum: 5 - maximum: 3846000) Hz was measured.

哑光面板的户外性能非常出色，即使在晴天，只要避免阳光直射，用户也可以将 T14s G4 带到户外。与半亚光 OLED 屏幕相比，该面板具有明显的优势。可视角度的稳定性无可挑剔。对比度会从上方角度降低，但这在实际使用中并不重要。

处理器 - Ryzen 7 7840U

......（英文 Ryzen 7 7840URyzen 7 7840U 属于 AMD 当前的 Phoenix U 代产品，提供 8 个快速 Zen4 内核，最高主频可达 5.1GHz，可同时处理多达 16 个线程。在 ThinkPad T14s 中，该处理器的功耗在短时间内达到 30 瓦，然后稳定在 24 瓦。因此，其性能不如 EliteBook 845 G10在后者中，处理器长时间保持 30 瓦的功耗，然后以 25 瓦的功耗运行。尽管如此，AMD ThinkPad 的性能仍然非常出色，而老式的 Ryzen 7 Pro 6850U在 ThinkPad T14s G3在所有基准测试中平均超出 17%。性能 酷睿 i7-1355U在长时间负载情况下的多核基准测试中毫无胜算，只能归功于开始时大幅提高的功耗限制。当两个 CPU 的功耗都为 24 瓦时，Ryzen 7 7840U 的速度要快 60%。只有在单核测试中，英特尔处理器才会凭借性能内核取得（微弱的）优势。在电池模式下，性能保持稳定。更多 CPU 基准测试请访问https://www.notebookcheck.net/Mobile-Processors-Benchmark-List.2436.0.html.

GPU-Z Radeon 780M

Radeon 780M Radeon 780MRadeon 780M 是一款快速的集成图形处理器，得益于双通道配置的快速 LPDDR5x 6400 内存。图形性能也明显优于英特尔机型，在合成基准测试中，AMD 机型要快 60% 左右。领先于 前代的 Radeon 680M在合成测试中仅领先不到 20%。

与 CPU 性能一样，GPU 性能在最初几秒后略有下降，这也是它未能通过Time Spy 95% 压力测试的原因。从根本上说，性能是稳定的，并且在长时间负载下也能保持稳定，我们的Witcher 3 长期测试也证实了这一点。在游戏测试中，Radeon 780M 明显快于英特尔的 Iris Xe Graphics G7在我们的标准游戏基准测试中，其领先优势约为 50%。这意味着旧版本和要求不高的游戏也能以高分辨率流畅运行。

在电池模式下，GPU 性能不会下降。更多 GPU 基准测试可在我们的技术部分.

温度

ThinkPad T14s G4 的表面温度绝对无害：压力测试结果最高仅为 42 °C。即使在满载情况下，笔记本电脑也可以毫不犹豫地放在大腿上。SoC 温度也稳定在较低的 60 °C，因此联想可以降低风扇转速或提高性能。

在综合 CPU/GPU 负载的压力测试中，处理器首先以 30 瓦的功率短时间运行，然后以 24 瓦的功率运行几分钟，最后稳定在 20 瓦。压力测试后，性能没有立即下降。

耗电量

T14s G4 AMD 的功耗非常低，尽管最大亮度更高，但与惠普 EliteBook 845 G10 相当，低于英特尔机型。全亮度时的功耗为 2.7 瓦至最大 5.6 瓦，设备效率非常高，负载下的功耗也低于英特尔同类产品，后者的短期功耗限制要高得多。因此，随附的 65 瓦电源完全够用。

充电曲线

57 Wh 电池的续航时间非常出色，与 OLED 机型相比，IPS 机型具有巨大优势。在调整亮度为 150 cd/m²（相当于我们测试设备最大亮度的 65%）的情况下，视频测试的运行时间略低于 16.5 小时，WLAN 测试的运行时间超过 13 小时。即使在全亮度状态下，该设备在 WLAN 测试中也能运行近 10 个小时。不过，电池电量可在 1.5 小时内耗尽（最大亮度下），但性能并未受到影响。

在评测了两款 ThinkPad T14s 之后，我们可以直接说，对于商务笔记本电脑来说，AMD 处理器和低功耗 IPS 面板的配置是更好的组合。AMD 处理器以更低的 TDP 提供更高的多核性能，在单核测试中也不落后于 Raptor Lake CPU。此外，图形性能也明显更高。

在显示屏方面，选择也很简单。sRGB 色彩空间完全满足日常办公使用的需要，而且面板比 OLED 屏幕更经济，后者还必须面对 PWM 闪烁的问题。除了大大延长电池寿命外，雾面 IPS 面板在户外也有更好的表现。

更强的性能和更长的电池续航时间：AMD Ryzen 处理器和雾面 IPS 显示屏确保联想 ThinkPad T14s G4 的性能更加出色，是市场上最好的商务笔记本电脑之一。

在 ThinkPad T14s G4 中做出选择非常明显，但如果比较 ThinkPad 和 惠普 EliteBook 845 G10 进行比较时，选择就变得更加困难了。这两款设备在很多方面都非常相似，而且都是目前最好的商务笔记本电脑之一。ThinkPad 的运行时间稍长，而 EliteBook 则凭借不那么敏感的机箱和可升级的内存取胜。此外，在配置相当的情况下，EliteBook 的价格也更便宜。总的来说，EliteBook 仍然是目前最好的商务笔记本电脑，尽管领先优势并不大。

价格和供应情况

作为 "黑色星期五 "优惠活动的一部分，ThinkPad T14s G4 目前在联想美国商店的销售折扣为 45%，起价 956.45 美元。

价格截至 2023 年 11 月 1 日，可能会有变动。
