联想 IdeaPad Slim 3 CB 14M868 评测--联发科 Kompanio 520 简介Chromebook
我们的新测试设备是在 "黑色星期五 "期间在亚马逊上购买的，价格令人难以置信，仅为 110 美元。目前，这款笔记本电脑的价格从 200 美元到 230 美元不等，是 2023 年 12 月最便宜的笔记本电脑。为了达到如此低的价格，联想不出所料地节省了不少开支。Chromebook ，你可以找到智能手机上常见的硬件，即联发科 ARM SoC、4 GB 内存和 64 GB 的慢速 eMMC 闪存。得益于其节俭的 ChromeOS 系统，这些硬件并不会让人望而却步。
你还可以选择配备 128GB eMMC 和 IPS 触摸屏的联想 IdeaPad Slim 3Chromebook （14 英寸联发科）。IPS 面板具有更好的可视角度，这可能会成为从我们测试设备的 TN 触摸屏升级的一个特别重要的原因。不过，在测试这款笔记本电脑的地区（DACH 地区），目前还没有这种笔记本电脑。取而代之的是基于 Alder Lake-N 的 14IAN8 型号，配备酷睿 i3-N305、8 GB 内存和 256 GB 闪存。售价超过 700 美元，完全是另一个价格区间。值得庆幸的是，你可以在美国找到配备 IPS 面板的机型。在美国，这个版本的售价约为 270 美元。
在支持区，联想还将这款设备列为 "IP Slim 3 Chrome 14M868 - Type 82XJ"。

案例
从外观上看，联发科技Chromebook 的塑料外壳比它的价格让人觉得质量更好。由于它也用于更昂贵的设备，你将从中受益匪浅。该机的设计灵感明显来自Apple 的 MacBook Air，其流畅的外形使其看起来非常漂亮。由于其边缘呈锥形，外壳看起来比实际要纤薄。遗憾的是，这款设备使用的塑料很容易造成划痕。尽管我们非常小心，但还是在测试设备的外壳上部发现了一些明显的划痕。与Apple 的铝制外壳相比，IdeaPad 在触感和稳定性方面可能无法与之相提并论，但考虑到其低廉的价格，我们对测试样品的外壳还是非常满意的。一个小缺点是，当你拿起笔记本电脑的一个角时，以及使用触摸板时（虽然它似乎没有使用实际的按键点击），你可以听到咔嗒咔嗒的声音。此外，我们的测试设备并没有完全均匀地放置在两只脚上。
与它的视觉灵感来源Apple MacBook Air 相比，IdeaPad Slim 3 厚了不少，尺寸介于 13 英寸和 15 英寸机型之间。与价格同样低廉的华硕Chromebook CM14 相比，IdeaPad Slim 3 的尺寸略小。
连接性
除了设备右侧的 Kensington 端口外，其他所有端口都位于左侧，这对惯用右手的人来说非常实用。USB-C 端口还用于为笔记本电脑供电，这意味着您有时可能需要依赖扩展坞才能使用它。不过，与另一个 USB-A 端口一样，Chromebook 只支持 USB 3.2 Gen 1（以前是 USB 3.0，因此 5 Gbps = 400 MB/s）。有了耳机接口和 microSD 插槽，实际上只缺少一个 HDMI 接口。由于联发科芯片的视频输出仅限于全高清，因此如果要连接外接显示器，也会受到同样的限制。
SD 读卡器
安装的 microSD 读卡器在我们的基准测试中成绩低于平均水平。与华硕的入门机型相比，联想的表现差强人意--不过，偶尔传输照片和文件时，它的性能还算可以。如果用作固定存储介质，其数据传输速率就会受到很大限制。

交流
在我们的测试中，集成的 WiFi 6 调制解调器（插入式 M.2 2230 2x2 模块联想 5W11H85391）工作完美，但也没有达到创纪录的速度。
网络摄像头
安装的网络摄像头可使用 ChromeOS 以 1280 x 960 像素拍摄中等质量的图像。如果光线充足，该摄像头足以满足视频会议的需要。网络摄像头上方的机械盖可以手动遮挡镜头。
配件
IdeaPad Slim 3 CB 只配备了一个小型的 45 瓦 USB-C 充电器，包装盒由回收纸板制成。不过，笔记本电脑是用聚苯乙烯固定的。
维护
Chromebook 可以比较容易地从底部打开。盖子由 9 颗 Torqx 螺钉和一些塑料夹固定。在内部，你可以更换 WLAN 卡、旋入式电池以及扬声器。
保修
IP Slim 3 Chrome 14M868 属于联想有限保修范围。您可以通过Lenovo 网站使用序列号查询个别产品的保修信息。.可提供保修升级。
输入设备
键盘 - Chiclet 键盘，采用典型的 ChromeOS 布局
IdeaPad 的键盘采用 ChromeOS 笔记本电脑的标准布局。单个 Chiclet 键的尺寸为 15.5 x 15.2 毫米，抬升高度为 1.4 毫米。如果你不习惯使用Chromebook ，那么你可能需要适应回车键和 "#"键之间的短距离。除此之外，按键布局也很舒适。从触感上来说，单个按键感觉有点廉价，而且容易发出轻微的响声。本文作者在这款键盘上打字速度很快（每分钟 92 个字），而且没有出现任何错误。
按键上的白色标签清晰易读，但没有背光。
触摸板 - 相当大
安装的触摸板相当大（对角线长 12 厘米），尽管表面是塑料的，但手感很好，而且很光滑。此外，触摸板底部五分之四的面积可以向下按压 0.7 毫米，从而产生令人满意的视觉点击效果。
显示屏 - 只能以良好的分辨率而自豪
在入门机型中，显示屏唯一值得称道的是它的分辨率。其 1920 x 1080 像素提供了不错的清晰度，尤其是因为 ChromeOS 可以很好地缩放用户界面并很好地描绘文本。屏幕中间的最大亮度为 281 cd/m²，在室内使用足够明亮，但在阳光下，即使是磨砂显示屏表面也无济于事。此外，它的亮度也不是最均匀的；底部三分之一的亮度要比其他地方暗一些。其黑色值尚可，对比度为 624:1。在色彩描绘方面，友达 208D 面板没有达到最佳数值。它的色彩偏差为 12.4（平均 DeltaE），有待改进。TN 面板的另一大缺点是视角稳定性差。即使你稍微移动头部，也会发现屏幕的亮度在变化。因此，我们拍摄的笔记本电脑视角照片显示出显示屏上的图案。我们很高兴地注意到，联想没有使用 PWM 来调暗屏幕。遗憾的是，这似乎是一块廉价的 6 位面板，因为我们在慢动作视频中看到灰度值时 出现了一些时态抖动 。

性能 - SoC 仅适用于要求不高的用户
其独特之处在于，联想Chromebook 采用了价格低廉、相对较新的联发科 Kompanio 520 SoC。它基于 ARM 技术，集成了 ARM 的 CPU 和 GPU。该 SoC 可访问 4GB 焊接式 LPDDR4X-3600 内存，采用 7nm 工艺制造。
测试条件
按照 ChromeOS 的惯例，没有控制 CPU/GPU 性能的选项。有关 SoC 的详细信息也几乎没有。由于Android 和 Linux 使用虚拟机运行，因此也没有提供太多细节。
处理器 - 小型、老式 ARM 内核
联发科 Kompanio 520 的处理器部分由两个集群组成，共有八个基于 ARM 的 CPU 内核。性能集群包含两个较大的 ARM Cortex-A76 内核，这两个内核来自于较早的智能手机处理器，如 高通骁龙 855.效率集群中有六个小型 ARM Cortex-A55 内核。所有内核的最高时钟频率均为 2 GHz。
在 CPU 性能方面，小型 ARM 内核只能赶上老式英特尔奔腾 N5030（双子湖四核，最高主频 3.1 GHz） 。新的 Alder Lake N 处理器，如英特尔 N100 ，速度要快得多。遗憾的是，我们的比较仅限于旧版 Geekbench 5.5，因为较新的 6.2 会导致重复性死机。

系统性能 - 入门级
联发科系统的系统性能也仅限于绝对的入门级水平。Kompanio 520 的 CrossMark 总分只能追上缓慢的 赛扬 J4125，远远落后于较新的 CPU。赛扬 赛扬 N4020经常被用于较旧的入门级笔记本电脑，却被甩在了后面。其 CrXPRT 2 性能也显示了类似的情况。Kompanio 仅落后于赛扬 N4500，但领先于 AMD 3015Ce。
在日常使用中，我们也能感受到这些较弱的基准测试结果。加载网站时有点卡顿，网页加载速度比速度更快的系统慢很多。此外，在观看 1080p 以上的 YouTube 视频时，会出现掉帧和播放滞后的现象。不过，由于Chromebook 不支持 1080p 以上的输出，这一点并不重要。

存储设备 - 慢速 eMMC 芯片
作为存储设备，联想Chromebook 依靠的是速度较慢的 eMMC 5.1 芯片焊接而成。入门机型有 64 GB，其中只有 46 GB 可以自由使用。Crostini 还需要 10 GB，这对于Android 、Linux 应用程序或自己的照片和视频来说，确实没有留下多少空间。

图形卡 - 智能手机的 Mali GPU
联发科 Kompanio 520 的图形卡是小型 ARM Mali-G52MP2 iGPU。用户只能使用六个内核中的两个，这种 iGPU 通常用于较旧的智能手机 SoC。它的性能（如在 GFXBench Aztec ruins Normal Offscreen 中）与智能手机变体相当，速度与赛扬 N4000 内的UHD Graphics 600 相似（如在 GFXBench Aztec ruins Normal Offscreen 中）。 联想Chromebook S340).在 DMark Wild Life 压力测试中，我们没有发现 GPU 有任何节流的迹象。另一方面，压力测试应用程序显示 CPU 略有节流，而在 NPU 负载较长的情况下，节流更为严重。

3DMark Wild Life Stress Test
游戏性能--不值一提
薄弱的图形处理器仅适用于一些简单的Android 游戏。例如，在我们的测试中，《PUBG》即使在最低的细节设置下也无法流畅运行，而《Asphalt 8》却可以玩得很好。Roblox的速度在 20 到 40fps 之间，具体视游戏而定。我们的测试设备无法使用最新版本的 Steam。
排放量
噪音排放 - 不存在
由于小型联发科处理器采用被动散热方式，因此联想Chromebook 即使在满载情况下也能保持静音。
温度 - 凉爽舒适
尽管 SoC 采用了被动散热，但笔记本电脑的表面温度仍然很低。在长时间 3D 图形负载后，我们在设备底部测得的热点温度仅为 33°C。
(+) The maximum temperature on the upper side is 32 °C / 90 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 33 °C / 91 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 24.9 °C / 77 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 26 °C / 78.8 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (+1.6 °C / 2.9 F).

扬声器--不适合音乐爱好者
笔记本电脑的两个 2 瓦立体声扬声器只适合简单的使用，如收听播客或 YouTube 视频。听音乐并不十分惬意。我们建议使用集成的耳机端口（遗憾的是，它也不能提供最好的音质，但至少不会产生任何可听到的背景噪音）。

运行时间 - 令人印象深刻
在续航时间方面，Kompanio 也是一个好伙伴。在我们的测试中，46 瓦时的电池在 150 尼特亮度下可使用 14.5 小时，在全亮度下可使用 11 小时多一点。这意味着在没有电源供应的情况下，一整天的工作时间都不成问题。这也比 华硕Chromebook CM14相同的 SoC，但电池容量只有 42 瓦时。
Chromebook 需要大约 2 个小时才能完全充满电池。它的充电功率为 50 瓦，在最初的 45 分钟内充电速度很快，然后迅速降至 30 瓦，从 1 小时 10 分钟开始逐渐接近零。
Pros
Cons
结论--物美还是价廉？
在我们的测试中，联想 IdeaPad Slim 3Chromebook 被证明是目前市场上最便宜的笔记本电脑之一。从外观上看，该设备给我们留下了高品质的印象。与它的价格相比，这款笔记本的做工和选材都很不错，但顶盖对划痕非常敏感。由于硬件配置较弱，你不得不在操作方式上做出一些妥协。对于要求不高的任务，如网上冲浪和办公用途，它的性能已经足够。另一方面，在玩从 Play Store 下载的要求较高的游戏时，SoC 很快就会接近极限。其较小和较慢的 eMMC 存储空间也限制了你的使用。此外，这款笔记本的扬声器只能算入门级，勉强适合听音乐。
值得庆幸的是，联想 IdeaPad Slim 3Chromebook 超长的运行时间，加上静音和低温运行，为这款设备代言。即使在负载情况下，它也能胜任。
遗憾的是，由于采用了 TN 技术，其全高清面板的可视角度非常差。色彩表现也不尽如人意。不过，对于简单的办公任务来说，这已经足够好了，而且由于采用了 1920x1080 像素的分辨率，其显示效果也非常清晰。
该笔记本电脑的一大优势是保证更新支持到 2033 年 6 月，而且 ChromeOS 还提供安全功能。
