耐力跑

华硕 CM 14Chromebook 是一种低成本的选择。不过，它也有一些优点，如 12 小时电池续航时间和 10 年更新保证。我们的测试揭示了华硕在哪些方面做出了妥协，以及Chromebook 在常规情况下的表现如何。

Chromebook Laptop / Notebook ARM

Chromebook 越来越受欢迎。华硕现在提供高性能的 Chrome OS 硬件，如 Chromebook Flip CX5配备英特尔 i7 处理器。另一方面，由于系统所需资源极少，Chromebook 在低预算市场尤其受欢迎。

我们所评测的设备就属于这类经济实惠型产品。售价为 299.99 美元的华硕 CM14（CM1402C）在知名零售商处的售价通常低至 200 美元左右。这使 CM14 成为最经济实惠的笔记本电脑之一，其性能也应得到相应的评估。

Chromebook 配有 4GB 或 8GB 内存，我们测试的是内存容量较小的版本。颜色只有烟灰色。华硕强调 CM14 结构坚固，称其符合 MIL-STD 810H 的特定要求。

外壳和连接性 - 华硕可折叠 180 度

与这个价位的产品一样，华硕为 CM14 选择了塑料外壳。磨砂的机身露出了个别闪亮的颗粒，提供了一个视觉上吸引人的外观，并且由于其表面略微粗糙而具有良好的握持感。相比之下，盖子则完全光滑，形成了视觉对比。

合上盖子时，显示屏会受到略微凸起的边缘和单独的橡胶部分的保护，以防损坏。当Chromebook 在桌面上打开时，显示屏会滑到机身下方，稍稍抬起，小橡胶脚垫会保护显示屏免受可能的损坏。

制造质量尚可，但盖子和机身都容易出现明显的凹痕。盖子也容易被划伤。CM14 的一个有趣功能是可以将显示屏打开 180 度。华硕默认内置了网络摄像头快门。

端口分布在两侧，但并不均匀。右侧只有一个 USB-C 端口和一个 LED。在左侧，华硕为 USB-C 版本配备了另一个 USB-C 端口、一个 USB-A 端口、符合 USB 3.2 Gen 1 标准的 USB 端口（提供电源传输）和 DisplayPort。此外，还有一个防盗装置（Kensington Lock 插槽）、一个 3.5 毫米插孔连接和一个 microSD 卡插槽。正面和背面没有连接。

两个扬声器位于设备底部，声音很容易通过外壳上的插槽从侧面传出。

交流

虽然华硕Chromebook CM14 支持 Wi-Fi 6，但我们测得的传输速率仍然不高。最大上传和下载传输速率分别为 444 MBit/s 和 248 MBit/s，这在目前的硬件中并不罕见。

在正常使用中，我们没有遇到任何网络连接问题，即使较大的文件也能快速简单地下载。这很可能是因为 WiFi 的传输速度仍可媲美快速的 100 MBit/s DSL。除了我们的测试设置外，设备中的天线位置和 WLAN 卡与散热器的距离也可能是造成高波动的原因。

在评估过程中，CM14 支持蓝牙 5.2，并能顺利连接控制器和耳机。华硕没有提供带 LTE 调制解调器的版本。

网络摄像头

华硕 CM14 配备了 720p 网络摄像头和便捷的机械快门。虽然华硕加入这一隐私保护功能值得称赞，但其图像质量却很一般。偶尔进行视频会议时可以使用，但照片和视频可能不太吸引人。

华硕提倡自动面部曝光，目的是在视频通话时增强面部亮度。不过，在测试过程中，我们没有观察到这方面有任何明显改善。

保修和维护 - CM14 的长期更新保修

使用底部附带的螺丝，可以很容易地接触到华硕Chromebook CM14 的结构。一颗螺丝上有密封圈。不过，内存和 RAM 是焊接到位的，而且没有风扇，这限制了维护选项。华硕提供为期 12 个月的保修服务。

，值得注意的是延长了更新保证期，因为Chromebook 在 2033 年 7 月之前都会收到系统更新。

输入设备 -Chromebook CM14，带大型触控板

华硕Chromebook CM14 的键盘采用了 Chrome OS 设备的标准布局。没有 F 键，而是音量、亮度等专用键，也没有数字键盘。按键宽度为 15 毫米，键程为 1.5 毫米。在Chromebook 上打字非常舒适，无需调整。CM14 没有背光键盘，按键听起来有点摇晃。

触控板是一大亮点。它的对角线长达 15 厘米，空间宽敞，受力点清晰，贴合度高，不会产生摩擦。滑动性能也值得称赞，而且触控板能可靠地识别手势。

显示屏 - CM14 上的深色 TN 面板

显示屏的质量明显反映了其价格范围。华硕选择了 CMN 的哑光 TN 面板。一个明显的缺点是最大亮度较低；我们测得的最大亮度为 230 cd/m²。此外，亮度也不是特别均匀，边角亮度明显下降。

显示屏的可读性在很大程度上受视角的影响。如果不直视面板，色彩还原和整体内容显示都会大打折扣，从锐利的角度几乎无法辨认内容。在测量过程中，我们观察到屏幕闪烁，尽管 24 800 Hz 的高频率表明其负面影响微乎其微。

虽然显示效果还有很大的提升空间，但仍符合同价位产品的预期标准。在惠普Chromebook 15a 上可以看到类似的数值，其屏幕中心的亮度为 260 尼特，略高于华硕 CM14，但华硕 CM14 的显示屏提供了更准确的色彩还原。

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
22.4 ms ... rise ↗ and fall ↘ combined	↗ 18.6 ms rise
22.4 ms ... rise ↗ and fall ↘ combined	↘ 3.8 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. » 46 % 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
37 ms ... rise ↗ and fall ↘ combined	↗ 18.9 ms rise
37 ms ... rise ↗ and fall ↘ combined	↘ 18.1 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. » 49 % of all devices are better. This means that the measured response time is worse 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 detected

24800 Hz

≤ 50 % brightness setting

The display backlight flickers at 24800 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 24800 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

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.

由于最大亮度较低，华硕 CM14 在户外使用时面临挑战。虽然磨砂面板有助于提高可读性，但即使在阴天，显示屏也很难正常工作。可视角度稳定性差进一步影响了可读性。

性能 - CM14 足以满足办公和网上冲浪的需求

廉价 Chromebook 的典型用途包括文字处理和浏览。因此，我们主要通过日常使用和浏览器基准测试来评估华硕Chromebook CM14 的性能。

处理器

华硕Chromebook CM14 配备了联发科 Kompanio 520(MT8186) 作为 SoC。芯片采用被动冷却方式，无需风扇。我们的测试设备配备了 4GB 焊接内存。

系统性能

华硕Chromebook CM14 的整体性能令人满意。它能为文档撰写和互联网浏览等任务提供足够的动力。不过，当打开六个或更多 Chrome 浏览器标签页时，性能开始下降，可能会出现轻微卡顿。

在常见的基准测试中，与其他设备相比，Chromebook CM14 通常处于中下游。HP HPChromebook 15a配备英特尔赛扬 N4500在这方面表现更好。

存储设备

华硕Chromebook CM14 的内置内存为 128 GB。而生产商使用的是 eMMC 内存。

我们测得的数值甚至低于 SD 读卡器的传输速度。由于 Chromebook 非常重视云计算，因此大多数 Chromebook 的存储速度都较慢，这也是可以忍受的。不过，即使对于Chromebook 来说，华硕 CM14 的速度也很差。

图形卡

华硕为Chromebook CM14 配备了集成的 ARM Mali-G52 MP2图形处理器。虽然该图形处理器完全可以胜任日常任务，但由于有谷歌 PlayStore 等平台或 Xbox Cloud Gaming 等云服务，Chromebook ，也可以玩当前的游戏。值得注意的是，由于设置的限制，某些游戏（如《PUBG Mobile》）只能以高清分辨率和高帧率运行。虽然可以玩，但偶尔可能会出现卡顿。

在我们的常用基准测试中，华硕 CM14 在对比设备中一直处于较低水平。在运行要求较高的程序时，小工具会出现明显的卡顿。

电池寿命 - CM14 可使用 12 小时

通过标准的 WLAN 测试，我们评估了华硕 CM14 的电池续航时间。Chromebook 的电池续航时间约为 12 小时，显示屏亮度为 150 cd/m2。因此，这款笔记本可以轻松地维持一天的工作或学习时间。只有采用相同芯片组的联想 IdeaPad Slim 3Chromebook 在电池续航时间方面超过了 CM14。

尽管配备了 45 瓦的电源，华硕 CM14 仍需要 100 多分钟才能充满电。充电进度如下：前 30 分钟达到 22%，1 小时后达到 58%，90 分钟后达到 93%。

+ 软件支持

+ 超大触控板

Cons

- 显示屏暗

- 视角稳定性差

结论 - 华硕 CM14 静音耐用，但速度较慢

华硕认为，CM14 是适合所有人的理想笔记本电脑。虽然不是，但它在很多方面都做得很好。它的性能足以满足办公应用、互联网浏览和一些游戏的需求。PlayStore 和 Linux 容器大大拓宽了应用程序的选择范围。

处理器的低性能也有其优势。尽管采用了被动散热，但温度并不高，功耗也很低。因此，在我们的测试中，Chromebook CM14 的运行时间达到了 12 小时。

如果能忍受显示屏暗淡和内存缓慢的问题，华硕 CM14 将是一款经久耐用、经济实惠、支持广泛更新的Chromebook 。

低廉的价格在 TN 面板上体现得尤为明显。显示屏的亮度并不特别高，平均亮度为 204 cd/m²。可视角度的稳定性也很差。华硕至少安装了哑光面板。内置内存的值也是可扩展的。读写速度较低。一线希望Chromebook 可以在云端存储大量数据。遗憾的是，无线局域网的传输速率同样不高。

我们很欣赏华硕 CM14 的输入设备。键盘的键程令人满意，触摸板大小适中。此外，我们对Chromebook 广泛的更新支持表示赞赏。

联想的 IdeaPad Slim 3 CB与联想的 IdeaPad Slim 3 CB 处于同一价格区间，采用了类似的处理器，但 WLAN 性能有所提高。惠普 HPChromebook 15a配备英特尔芯片，性能略胜一筹，但电池续航时间稍短。

价格和供应情况

华硕Chromebook CM14 的配置版本在华硕官方网站上的零售价为 299.99 美元。官方网站上的零售价为 299.99 美元。包括亚马逊在内的多家零售商也有销售。
