LG Gram 16 (2022) 笔记本电脑评论。具有稳定性问题的轻量级设备
我们测试的模型（16Z900）价格为1300欧元，当然不是你在办公室领域找到的最便宜的交易。该设备配备了一个酷睿i7-1260P英特尔桤木湖一代的Core i7-1260P，16GB焊接的DDR5内存（5200MHz）和M.2格式的1TB NVMe SSD。图像显示在一个16英寸16:10的IPS屏幕上，像素为1560 x 1600，据说覆盖了P3色彩空间的100%以下（与15英寸的MACD不同）。 15英寸的模型模型，我们最近测试过）。操作系统是Windows 11 Home 64位。
LG Gram 16的竞争对手（大部分都比较重）包括其他配备酷睿i7-1260P的16英寸笔记本，如 联想瑜伽7 16IAP7和戴尔 Inspiron 16 7620，尽管这些设备实际上是可转换/二合一笔记本。我们还包括 联想ThinkPad T16 G1配有酷睿i5-1240P的联想ThinkPad T16 G1也在比较之列。这个设备的iGPU只有80个而不是96个EU。

案例
除了一些小的细节（摄像头的形状，关键的标签），这个箱子看起来和去年的版本完全一样。据LG称，它是由镁合金制成的，这在纸面上听起来不错。在实践中，我们对这种材料没有留下特别深刻的印象。它给我们的感觉和声音更像是塑料，而且--这是一个更大的问题--不是非常坚硬和稳定。特别是底座的中心对压力非常敏感，显示屏的盖子很容易变形。笔记本电脑可能会受益于稍厚（这也意味着更重）的材料。
没有任何设备能与Gram 16的低重量竞争。它只有1.2公斤，非常容易随身携带。竞争对手的重量要大得多，约为2.0公斤，尽管这也使他们更加稳定。我们对这款16英寸设备的外观非常满意。由于其窄边框和优雅而谨慎的设计（根据型号，Grams有白色、灰色或黑色可供选择），该笔记本在任何情况下都会很好看。做工令人满意，铰链也做得很好，尽管盖子在受到振动时往往会很快滑落。
连接性
端口选择
端口的选择与老款Gram 16相似。左侧有一个HDMI端口（没有进一步的规格）、一个音频插孔和两个支持Tunderbolt 4、DisplayPort和Power Delivery的现代USB 4端口，右侧有一个microSD读卡器、一个Kensington锁和两个经典的USB A端口（3.2 Gen2）。所有的端口都位于设备的背面，这使得用户在使用外部鼠标时有足够的空间。与其他Grams不同，该设备没有配备USB-to-LAN适配器。
SD卡阅读器
该读卡器的性能一般。它在连续读取时达到87MB/s的速度，用我们的参考SD卡传输照片时达到76MB/s。这些结果与联想Yoga 7的结果非常相似。

沟通
新款Gram在Wi-Fi速度方面有别于其前辈。LG已将该设备从英特尔Wi-FI AX201升级到Wi-Fi AX 211。在距离我们目前的参考路由器（华硕ROG Rapture AXE11000）1米处，这台16英寸的笔记本电脑在发送和接收时达到了约1600 Mbit/s。这是一个很好的结果。

网络摄像头
虽然网络摄像头的分辨率略高（全高清），颜色也比大多数办公笔记本更准确，但你一定不要对Gram 16的网络摄像头期望太高。
辅料
除了一个很好的轻巧的65瓦USB C电源适配器外，该设备只配备了一些小册子。
维护
Gram 16的任何维护工作都会相当复杂，因为所有的螺丝都隐藏在橡胶盖下面。因为我们的测试设备是从网上商店而不是从制造商那里收到的，所以我们选择不打开机箱。
担保
该设备有24个月的保修期。
输入设备
键盘
除了微不足道的稳定性之外，这款键盘给我们留下了良好的印象。虽然布局（德国版的小单排回车键、小方向键、三栏数字键盘......）和反馈/打字并不完美，但我们相信大多数买家应该对该键盘非常满意。正如预期的那样，该设备具有两级亮度的白色背光灯。
触摸板
触摸板大得令人满意，为13 x 8厘米。相对光滑的表面确保了良好的滑行性能，精确度和手势支持也令人满意。可点击的底部部分使用起来很舒适，但有些摇晃，这影响了感知质量。
显示
虽然新的屏幕由于黑值略高（0.32而不是0.22cd/²），对比度较低（1144:1而不是1505:1），但我们对哑光屏幕比前代的反射面板更满意。

光度略微提高了40cd/m²（347而不是309cd/m²），这使得Gram 16在明亮的环境中更容易工作，特别是在户外工作时（尽管仍有很大的改进余地）。与前一年的机型相比，色彩准确性也有所提高。即使在出厂时，Delta 2000的值也在3以下的理想范围内。
在响应率（仍然平平）和色彩空间覆盖率方面没有任何改进。后者在去年已经非常好，几乎100%覆盖了sRGB/P3色彩空间，85%覆盖了AdobeRGB。视角是你对IPS显示屏的期望。
我们希望下一个版本将配备更加明亮的显示屏，达到400甚至500尼特，并有更快的刷新率（144+而不是60赫兹）。

业绩
Gram 16的性能在办公笔记本中属于中等水平。16GB的内存和1TB的固态硬盘应该足以满足大多数用户未来一年的需要。
测试条件
易于使用的LG智能助手让你从各种选项中选择冷却模式。除非另有说明，我们的测试都是在标准的 "正常 "设置下进行的。
处理器
酷睿i7-1260P拥有四个支持超线程的性能核心和八个无超线程的效率核心。这意味着，该芯片总共可以并行工作16个线程。Gram 16在Cinebench循环中的表现不是特别好，Cinebench循环测量的是一段较长时期的性能。首先，因为它的性能从第二轮开始明显下降，其次，因为在整个测试过程中，结果波动很大。这对冷却或能源管理来说不是一个特别好的迹象。冷却模式 "高"（见图）避免了这个问题，但也使设备的声音明显增大。

图形
目前英特尔的大多数笔记本CPU都配备了 Iris Xe Graphics G7.其性能不仅取决于TDP和冷却系统，也取决于计算单元的数量。例如，酷睿i7-1260P的iGPU配备了96个EUs，而同样受欢迎的酷睿i5-1240P只配备了80个EUs。不幸的是，Gram 16不能充分利用其96个EUs。3DMarks将LG笔记本定位在比较领域的中心，尽管明显高于80EU的版本。我们将在游戏基准测试部分看到3D性能是否保持稳定。

游戏性能
Iris Xe Graphics G7 GPU往往更适合于中等分辨率和设置的老游戏。正如你可以在我们的 GPU页面在玩新的或要求更高的游戏时，iGPU往往无法与之竞争，通常甚至无法在全高清的低细节下流畅地显示游戏（更不用说在2560 x 1600的原始分辨率下）。

排放
系统噪音
虽然新的Gram 16没有更好的GPU性能，但该设备在负载下的噪音比其前辈要大得多，尽管在3D操作中37-38而不是31 dB(A)仍然是非常可以接受的，比联想Yoga 7低。 在空转时，LG笔记本的噪音为26至28 dB(A)，令人舒适。并不是说风扇不能完全关闭。这需要使用静音模式，不幸的是，由于性能的极度下降（例如，YouTube视频和其他在线流变得生硬），这不是一个选项。

压力测试
由于组件即使在正常条件下也开始节流，我们并不感到惊讶，在最大负荷下，性能非常不稳定，而且受到限制。非常清楚的是，LG在制造Gram 16时考虑到了最大的移动性，而性能所起的作用则不那么重要。
发言人
考虑到这台笔记本的尺寸和重量，考虑到低音较弱，扬声器的表现出乎意料的好。在质量和最大音量（84 dB(A)）方面，声音可以轻松地跟上其竞争对手。

判决书
LG Gram 16Z90Q配备了一台酷睿i7-1260P是在考虑到便携性的情况下制作的，对性能有高要求的用户不太关注。
紧凑而轻巧的机身在你外出时特别实用。
该设备不仅舒适小巧，重量轻，而且还拥有出色的电池寿命。另一方面，当连接到主电源时，这台16英寸设备相当令人失望。标准的冷却模式导致CPU、SSD和iGPU性能的极端不稳定。机箱的微弱稳定性也可能使一些潜在的买家望而却步。
除此以外，我们真的找不到关于16英寸LG Gram 16的批评。它有一套现代的端口（2x USB 4），良好的输入设备和标准排放。声音和图像质量都很好，由于其2560 x 1600像素，哑光IPS屏幕具有良好的色彩和出色的分辨率。
的联想ThinkPad T16是一个很好的选择，尽管它有一个（甚至）更高的价格标签。
