联想 V17 G4 评测：经济实惠的全能笔记本电脑，显示屏带来惊喜
令人兴奋的入门级处理器
如果您正在寻找一款经济实惠的办公和多媒体全能型产品，那么联想的 V17 G4 IRU 可能会是您的首选。这款 17 英寸的设备采用了英特尔 U300 这一相对罕见的 CPU，而且其画质出奇的好。Florian Glaser, 👁 Florian Glaser (translated by DeepL / Ninh Duy) Published 🇺🇸 🇩🇪 ...
评价 - 日常良伴
联想 V17 G4 IRU 的估计售价约为 470 美元，给人的印象还算不错--至少如果不考虑其 iGPU（UHD Graphics Xe G4，48EUs）糟糕的图形性能的话，它的图形性能明显落后于 Iris Xe Graphics G7（80 或 96EUs）。虽然该笔记本电脑的外壳仅由塑料制成，但看起来却像是由金属制成的。此外，它还配备了实用的端口和良好的输入设备（尽管键盘没有背光），这在这个价位的笔记本电脑中并不常见。
其他亮点还包括它的屏幕。是的，它的对比度和黑度等某些方面还可以做得更好，但它的色彩空间覆盖率几乎达到了 90% sRGB，这在预算有限的同类产品中是出类拔萃的。它的电池续航时间（在亮度降低的情况下上网冲浪约 7 小时）也不赖。适中的排放使整套配置更加完美。另一方面，联想将 8GB 内存焊接在机身上（至少还有一个空闲的 SO-DIMM 插槽用于扩展），而且该设备只有一个 M.2 插槽，这有点令人遗憾。此外，制造商还需要解决固态硬盘偶尔出现的节流问题以及笔记本电脑的网络摄像头问题。

请注意：目前市场上有两款名为 V17 G4 IRU 的设备。其中一款搭载了 酷睿 i5-1335U而我们测试的版本则配备了（速度较慢的） 英特尔 U300.
规格
案例
联想选择了更为低调的外壳设计，没有任何装饰或噱头。主观而言，灰色表面比黑色表面的笔记本电脑更不易沾染指纹。机箱的稳定性好坏参半。在某些地方，V17 相当坚固，而在另一些地方，它则会明显屈服和弯曲。由于铰链调整得很紧，所以需要很大的力量才能打开，单手是无法打开设备的。值得庆幸的是，我们对这款笔记本电脑的外观质量没有任何意见。
V17 的重量约为 2.1 千克，并不一定是最轻的笔记本电脑之一，不过它的尺寸自然也是原因之一。同时，2 厘米的高度既不算多，也不算少。
连接性
端口
除了一个 RJ45 端口外，V17 还配备了所有常见的接口。除了音频接口外，买家还可获得一个 SD 读卡器和一个 HDMI 端口（遗憾的是只有 1.4b）。此外，还有两个 USB-A 端口（1 个 2.0、1 个 3.0）和一个带 DisplayPort 和 PowerDelivery 功能的 USB-C 端口。由于端口位于侧板的后半部，因此插入的线缆不会碍事。
SD 读卡器
在我们的测试中，安装的读卡器提供了略低于 90 MB/s 的稳定性能（例如，在顺序读取和传输照片时）。

交流
Realtek 的无线模块（RTL8852BE）未能达到最高性能值，而是排名中游。即便如此，对比设备的性能值也相差无几。
网络摄像头
值得称赞的是，制造商为该机配备了实体网络摄像头快门。网络摄像头本身的图像质量相当差，这一点我们在大多数笔记本电脑上都能看到。其色彩准确度和清晰度也有待提高。
配件
这款笔记本电脑配备了一个相当小巧的 65 瓦电源装置，因此仍然便于运输。
维护
在拆卸底板之前，首先要拧松 10 颗 Torx 螺钉。从照片中可以看到内部结构的设计。例如，空闲的内存插槽就隐藏在一个盖子下面。尽管笔记本有 2280 插槽，但联想只使用了 2242 型号的固态硬盘。
可持续性
它的包装并非完全不含塑料。电源线的袋子和笔记本电脑的保护膜和衬垫都是塑料制成的。至少每种材料都有适当的标签。
保修
笔记本电脑享有 12 个月的标准保修服务。
输入设备
键盘
正如我们在介绍中提到的，该设备的输入设备令人印象深刻。键盘采用典型的联想设计，按键的形状也是如此。该机型的打字性能可与许多更昂贵的笔记本电脑媲美，我们认为它适合经常打字的用户使用。由于空间充足，联想还集成了一个功能齐全的数字键盘，尽管其按键比主键盘窄了一些。不过，在黑暗或光线不足的环境中，一些背光功能会有所帮助。如今，后者确实应该成为标准配置。
触摸板
与所有其他尺寸相比，触摸板感觉相当小。大约 10.5 x 7 厘米的尺寸在 17 英寸的产品中并不罕见。我们认为它的精度和流畅度都不错，但点击区域有些不稳定和不稳定。不过，总的来说，这款鼠标的替代品仍然达到了 "良好 "的评级。
显示屏
基于 IPS 技术的全高清显示屏在许多方面的表现只能说是合格。无论是平均 305 cd/m² 的亮度，还是 0.38 cd/m² 的黑度，都不足以满足户外使用的要求，从而导致 868:1 的对比度表现平平。

另一方面，V17 G4 的色彩空间覆盖率也让我们感到惊喜，因为大多数廉价笔记本电脑在这方面还有很多不足，通常最多只能达到 60% 的 sRGB 覆盖率。而 V17 G4 的 sRGB 覆盖率略低于 90%，可提供相当强的差异化图像，从而使电影等媒体的显示效果达到最佳。
就其响应时间和视角稳定性而言，按照 IPS 标准，没有什么可抱怨的。
只是它的色彩准确度有些令人失望（略微偏蓝），但这可以通过校准屏幕来弥补（像往常一样，我们的 ICC 文件与照明图相链接）。

性能
联想 V17 G4 IRU 显然属于入门级产品。英特尔的 U300-正如我们稍后将展示的那样，它并不具备飞跃性的能力。8 GB RAM 也是边缘配置，尤其是在 iGPU 方面，不过您可以轻松扩展其工作内存。
测试条件
在预装的 Vantage 软件中有三种运行模式可供选择（见截图），我们在测试中使用了默认激活的 "自适应能源模式（自动）"配置文件。
处理器
U300 是英特尔 Raptor Lake U 代处理器中速度最慢的一款。这款 10 纳米机型只能使用一个性能内核（包括超线程），尽管它有 4 个效率内核支持。尽管如此，它的性能还是偏低。尽管 U300 比 酷睿 i3-1115G4 (至少在 CPU 方面）更快，而该芯片直到最近还在经济型电脑中颇受欢迎，但它与 酷睿 5 120U或 酷睿 7 150U(更高性能或更高效率的内核）。

系统性能
V17 G4 在系统性能方面也很吃力。PCMark 10 的 4370 分并不令人印象深刻。从主观上讲，这款笔记本有时会感觉有些迟钝，尤其是在加载时间方面（例如玩游戏时）。多任务处理也不是联想笔记本电脑的强项之一，17 英寸设备很快就达到了极限。

存储设备
笔记本电脑的大容量存储设备已经达到了预期目的，但并没有引起热烈的反响。即便如此，在我们的测试过程中，安装的 512 GB WD 硬盘（型号 PC SN740）在长时间负载后仍会出现性能波动，这与 IdeaPad Slim 3i 的对比设备类似，我们的 DiskSpd 循环也证明了这一点。

游戏性能
除了基本性能较低之外，笔记本电脑有限或缓慢的内存也成为运行游戏时的问题，尤其是其驱动程序支持似乎也不完善。许多在 2023 年和 2024 年发布的游戏，我们其实都想进行测试，但它们要么根本无法启动（错误信息），要么尽管有最新的驱动程序却崩溃了：

排放量
噪音排放
这款笔记本电脑的噪音适中，因此获得了加分。在空闲模式和执行简单任务时，风扇通常会保持安静（要么完全关闭，要么保持在 26 至 28 分贝的低噪音水平）。在负载情况下，你也不必担心风扇的问题：在 3DMark 06 中，我们注意到风扇的噪音仅为 34 分贝（A）。只有在极端条件下，例如我们的压力测试，17 英寸设备的噪音才会达到 41 分贝（A）。

温度
其温度也与此类似。在空闲状态下，整个机箱的温度保持在 30 °C以下，使用起来非常舒适。在负载情况下，我们的测试中有些测量点超过了 40 °C，但总体而言，其数值还算可以。

压力测试
在使用 Furmark 和 Prime95 工具进行的压力测试中，CPU 的发热量并不大：平均温度略高于 60 °C，完全没有问题。
发言人
它的音质既不算好，也不算特别差，完全达到了平均水平。与通常情况一样，2.0 系统在低音方面也有不足之处。它的最大音量为 76 dB(A)，还可以做得更好。

耗电量
考虑到处理器的性能，这款笔记本电脑的功耗要求还是相当合理的。31 至 58 瓦的负载功耗与老款酷睿 i3-1115G4 类似。在空闲模式下，我们的测量设备发出的功率为 4 至 12 瓦--也是合理的值。
