联想 ThinkBook 13x G4 笔记本电脑评测：除键盘外最好的笔记本之一
ThinkBook 系列的机型主要面向那些不想花高价为员工购买 ThinkPads 的企业客户。新款 ThinkBook 13x G4 是一款紧凑型子笔记本电脑，个人买家可能也会对它感兴趣，因为它具有不错的性能、大容量电池、高分辨率 3:2 IPS 显示屏、磨砂表面和铝制机身，售价约为 1100 美元。
。
我们测试的 ThinkBook 13x G4 型号为 21KR0008GE，配备了 Core Ultra 5 125H、16 GB 内存、512 GB 固态硬盘存储空间和 2.8K 显示屏（2880 x 1920），售价为 1,106 美元。

机箱 - 采用铝制机箱的 ThinkBook
从根本上说，ThinkBook 13x G4 的设计与其他廉价机型并无不同，银灰色的外壳采用了双色盖子，上面印有大字，第一眼看上去非常朴素。ThinkBook 16 G6 等廉价机型通常只有铝制屏幕盖，其余部分均由塑料制成，而 ThinkBook 13x G4 的底座也使用了铝制材料。底座的侧面经过抛光处理，整体外观非常有质感。底座两侧没有采用锥形设计，这使得该设备看起来比实际要笨重一些。
与其他机型一样，联想也使用了摄像头驼峰，在这里看起来非常大。它看起来并不美观，但至少在打开盖子时有帮助。打开盖子时有两点很明显：屏幕边缘非常窄，而且与 ThinkPad 相比，打开角度明显受限，最大只有 135 度。不过，铰链本身调整得很好，除了在调整角度时会有轻微的摇晃外，它能牢牢地固定盖子。尽管设计很薄，但盖子非常稳定，我们无法看到任何图像错误或失真。底座的稳定性非常好，只有中间的键盘区域在压力下会有轻微晃动。没有发现吱吱作响的声音。做工也无可挑剔。
如前所述，ThinkBook 13x G4 的设计使其看起来更厚一些，但表象具有欺骗性，其高度仅为 12.9 毫米，是我们对比组中最薄的设备之一，仅次于 MacBook Air M3.不过，与 Air M3 相比，联想笔记本电脑在桌面上占用的空间更小，也是整体最紧凑的机型之一，因此可以轻松放入任何包中。不过，1.2 千克的重量也是最重的设备之一，65 瓦的插拔式电源又增加了 191 克。官方数据表还提到了重量约为 1 千克的镁合金机型，但我们未能找到相应的配置。
装备 - 3x 雷电 4
联想为 ThinkBook 13x G4 配备了三个快速 USB-C 端口，其中包括 Thunderbolt 4。这个接口的位置乍看起来有点不寻常，但实际使用起来却非常实用。其中一个端口位于右前方，可以方便地连接 U 盘，设备两侧都可以充电。不过，USB-A 设备需要适配器，而且也没有读卡器。也有采用联想 Magic Bay 连接技术的可选机型，在这种情况下，摄像头驼峰会更厚，并配备 pogo pins。4K 网络摄像头等可选配件就可以连接到这里。
交流
ThinkBook 13x G4 尚未安装 WiFi 7 模块，但安装了著名的英特尔 AX211 模块。它支持 WiFi 6E 和蓝牙 5.3。在使用华硕参考路由器进行的测试中，传输速率非常高且稳定。信号稳定性也没有问题。

网络摄像头
显示屏上部边框中的 1080p 网络摄像头可以正常工作，但你不应该期待它创造奇迹。此外，还有一个红外传感器，可通过 Windows Hello 进行面部识别。
维护
打开机箱后，我们大吃一惊：虽然底板可以轻松拆卸，但维护选项却非常有限。电池连接在底盖上，并通过一根带状电缆与主板相连，电缆也是用螺丝固定的。维护手册中也有说明，但对于没有经验的用户来说，操作过程可能会很麻烦。
输入设备 - 触觉触摸板，但键盘较弱
键盘是 ThinkBook 13x G4 的弱点之一，因为键程很短，输入体验不是很舒适。按键本身很精确，声音也不大，但如果你经常打字，并且习惯于键程较大的键盘，那么在购买前应尽可能测试输入效果。键盘布局简单明了，现在还有一个副驾驶键，不过垂直方向键比较小。键盘提供两段式白色背光，也可通过传感器自动激活。
触觉触摸板可用于指针控制，通过振动电机提供反馈。这种方法效果很好，但 "嗒嗒 "声可能会更小一些。这种解决方案的优点是，你可以点击触摸板上的任何位置，并获得相同的反馈。玻璃表面的滑动性能非常出色。12 x 7.5 厘米的尺寸为移动/手势提供了足够的空间。
显示屏 - 2.8K IPS，120 赫兹
联想在 ThinkBook 13x G4 上放弃了 OLED 屏幕，转而安装了 3:2 格式的高分辨率 IPS 面板。得益于 2880 x 1920 的分辨率，所有内容都非常清晰，色彩鲜艳，即使没有达到 OLED 的水平。总体而言，主观画质非常好，明亮区域不会出现颗粒感，运动也因频率的增加而受益。没有 PWM 闪烁也是一大优势，响应时间也不明显。亮度和色温都是通过传感器自动调节的。
平均亮度为 513 cd/m²，黑阶略高，为 0.38 cd/m²，但对比度仍然很高。光晕问题不大，面板还支持 HDR 内容，但最大亮度仍为 540 cd/m²。

* ... smaller is better
显示器已经调整得很好，使用专业的 CalMAN 软件（X-Rite i1 Pro 2）进行分析，只显示出极小的偏蓝，在实际使用中并不明显。与 sRGB 参考色彩空间相比，所有色彩都已低于 DeltaE-2000 3 的重要临界值，因此校准并非绝对必要。我们通过自己的校准（相应的配置文件可在上面免费下载）在一定程度上改善了显示效果，也消除了最小偏色。sRGB 色彩空间几乎完全覆盖，因此 ThinkBook 适用于视频和图像编辑。

明亮的哑光 IPS 面板在户外表现非常出色，当然应避免阳光直射及其反光（见图）。视角稳定性也没有问题。
性能 - Core Ultra 和最高 32 GB 内存
有趣的是，联想只提供配备了 酷睿 5 125H或 Core Ultra 9 185H但流行的 酷睿至尊 7 155H则无法使用。此外，您还必须选择 Core Ultra 9，才能将内存从 16 GB 升级到 32 GB，而这两种情况都会产生适度的附加费用。
测试条件
像往常一样，联想提供了多种电源模式，与 ThinkPad 机型不同的是，这些模式与 Windows 的电源设置没有直接联系。这些配置文件可以通过预装的 Vantage 软件或 Fn+Q 组合键进行切换。我们在下表列出了相应的 TDP 值。在测试中，我们使用了默认激活的 "自动 "配置文件。
| 电源模式 | TDP | CB R23 Multi | Time Spy 图形 | 最大风扇音量 |
|---|---|---|---|---|
| 电池保护 | 44 -> 18 瓦 | 5,536 点 | 2,471 点 | 33.9 分贝(A) |
| 自动 | 51 -> 28 瓦 | 9,194 分 | 3,248 分 | 40.7 分贝(A) -> 36.8 分贝(A) |
| 性能 | 51 -> 35 瓦 | 12,188 分 | 3,382 分 | 42.5 分贝(A) |
在性能模式下，处理器的运行时间明显更长，为 51 瓦，而在自动模式下仅为几秒钟。如果你需要最大限度地提高 CPU 性能，这种模式是值得的。对于日常生活中要求不高的任务，你可以毫不犹豫地使用省电模式，并从更安静的风扇中获益。
处理器 - Core Ultra 5 125H
核心 酷睿至强5 125H在我们的测试设备中属于英特尔当前的 "流星湖 "一代，比广泛使用的 酷睿至尊 7 155H.现有的四个 P 核心的最高时钟频率也较低，最高为 4.5 GHz。在 ThinkBook 中，处理器的功耗在几秒钟内高达 51 瓦，然后稳定在 28 瓦，这在我们的 Cinebench 循环中可以清楚地看到。这样的性能水平完全可以满足日常任务的需要，但结果并不理想，酷睿 Ultra 5 处理器与 AMD 的 Zen4 处理器相比毫无胜算。Apple被动冷却的 M3在单核和多核测试中也有更好的表现。在电池模式下，该处理器的功耗也可高达 51 瓦，但随后会迅速降至 25 瓦，这也是其性能略低于电源模式（-4%）的原因。更多 CPU 基准测试可在我们的 技术部分.

联想安装了一个带有 PCIe 4.0 连接的紧凑型 M.2-2242 SSD，在我们的测试设备中，它来自三星（PM9C1a），提供 512 GB 的存储容量。首次启动后，剩余容量为 422 GB。传输速率尚可，但在长时间负载情况下性能并不稳定。不过，在日常使用中，这并没有影响，因为性能仍然足够（超过 3.3 GB/s）。更多固态硬盘基准测试 这里.

图形卡 - 配备 7 个 Xe 内核的 Arc Graphics 图形卡
与Core Ultra 5 125H 配合使用的是速度较慢的集成Intel Arc Graphics ，带有 7 个 Xe 内核。得益于快速的内存，图形性能整体上非常出色，与我们迄今测试过的配备更快 8 核变体的笔记本电脑几乎没有差别。这同样适用于Dell XPS 13 9340 和MSI Prestige 13 AI Evo 。ThinkPad Z13 Gen2 采用 AMD 处理器和Radeon 780M ，在合成测试中的表现也优于 AMD 处理器。
在游戏基准测试中，Radeon 780M 仍略胜一筹，但 ThinkBook 13x G4 再次领先于据称速度更快的戴尔 XPS 13 和微星 Prestige 13。在游戏过程中，我们也没有发现任何掉帧问题。一般来说，许多较老或要求不高的游戏都能在 1080p 下以中高细节流畅运行。不过，对于《赛博朋克 2077》等现代游戏，情况就会变得紧张，除了降低分辨率或减少细节外，还应该使用升频技术。
在长时间负载和电池模式下，图形性能保持稳定。更多图形基准测试，请访问我们的技术部分 。

温度
联想很好地控制了 ThinkBook 13x G4 的表面温度。设备在空闲和低负载状态下几乎不会发热，只有一个热点在负载状态下温度超过 40 °C。这是在键盘上方的底座上，反正你也不接触设备。底部的最高温度为 39 °C，因此即使在负载情况下，将设备放在大腿上也不会有问题。在 CPU/GPU 综合负载压力测试中，SoC 很快稳定在 28 瓦，并保持在这一水平。
(±) The maximum temperature on the upper side is 43.1 °C / 110 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.

ThinkBook 13x G4 提供四个扬声器，包括两个高音扬声器和两个低音扬声器，每个扬声器的功率为 2 瓦，因此音质非常出色。在这方面，ThinkBook 甚至可以与 MacBook Air 13.与大型多媒体笔记本电脑相比，低音效果略显有限，但考虑到机身尺寸，效果仍然非常不错。

耗电量
我们的功耗测量结果显示，高分辨率和高亮度面板所需的电量并没有出乎我们的意料，例如，比配备 1080p 屏幕的 XPS 13 稍高一些。闲置模式下的最大功耗为 8.9 瓦，并不算高。在最大负载情况下，设备会短暂达到 65 瓦电源的极限，但几秒钟后就会降至约 45 瓦，然后保持在这一水平。

电池寿命
在我们的 WLAN 测试中，ThinkBook 13x G4 凭借 74 Wh 的大容量电池实现了良好的运行时间，但并不突出。在 150 cd/m²（相当于测试设备最大亮度的 56%）的条件下，我们在 60 Hz 和 120 Hz 条件下分别测得 11.5 小时和 10.5 小时。在全亮度条件下，我们仍能使用 9 小时（60 Hz）和 7.5 小时（120 Hz）。在 150 cd/m² 的视频测试中，ThinkBook 达到了出色的 20.5 小时，明显优于所有竞争对手。在满负荷和最大亮度下，仅用了不到 2 小时就结束了测试。在设备开启的情况下，充满电需要 113 分钟（66 分钟后达到 80%）。此外还有快速充电模式，但对于 65 瓦的电源装置而言，这种模式并不具有任何优势。

评价--如果你能接受键盘，ThinkBook 13x G4 是一款出色的子笔记本电脑
ThinkBook 13x G4 让我们大吃一惊，因为联想推出了一款移动性很强的超极本，采用高品质金属机身和 3:2 雾面屏幕。ThinkBook 13x G4 在做工和稳定性方面没有任何限制，而且你也不会期望在 ThinkBook 上使用金属机箱（通常只有盖子是铝制的）。有三个 Thunderbolt 4 端口，在日常使用中有时需要适配器，但应该足够了。不过，由于电池连接在机箱底部，因此维护选项有限。
性能 酷睿至尊 5 125H的性能足以满足日常使用，但并没有创下任何记录。事实上，考虑到 28 瓦的功率限制，我们更倾向于使用 AMD 处理器。Core Ultra 9 185H 也可以选配，但需要支付高昂的附加费。32 GB 内存也只能与 Core Ultra 9 结合使用。120 Hz 的哑光 IPS 屏幕在各方面都令人印象深刻。主观画质不如 OLED 面板，但没有反光，也不存在 PWM 闪烁。电池续航时间完全可以接受。此外，它还集成了带四个扬声器的出色音频系统。
联想的 ThinkBook 13x G4 凭借高品质的机身、出色的扬声器、出色的 IPS 显示屏和超长的电池续航时间给人留下了深刻印象。不过，键盘也有其局限性。
除了包括焊接内存在内的维护选项少之外，ThinkBook 13x G4 的另一大弱点就是键盘。虽然键盘敲击有力，但键程非常有限，这明显影响了打字的舒适度。当然，你可以适应这种键盘，这也与你以前使用过什么样的键盘有一定关系，但如果键程再大一些，就可以很容易地避免这种情况。戴尔 XPS 13 9340 的键盘 戴尔 XPS 13 9340例如，戴尔 XPS 13 9340 的键盘更加舒适，但用户不得不忍受不寻常的布局和电容式功能键。总的来说，13x G4 的性价比要高得多。MacBook Air M3 Apple MacBook Air M3仍然是一个强劲的竞争对手，它结合被动散热技术提供了更高的性能，但只使用 60 Hz 显示屏。
价格和供应情况
在联想的美国网店上，Thinkbook 13x Gen 4 的基本型号起价为 1106 美元。当然，还可以配置更强大的 CPU、额外的内存和更大的存储空间。
