LG Gram 15 (2022)笔记本电脑回顾。专注于便携性
由于我们已经审查了2022年版本的 LG Gram 17和 LG Gram 14，刷新的15英寸版本是该阵容中唯一仍然缺少的设备。
我们对15Z90Q的配置包括一个 酷睿i5-1240P英特尔桤木湖一代的酷睿i5-1240P，16GB（焊接的）DDR5-RAM，以及1TB M.2 SSD。显示屏采用了哑光IPS面板，长宽比为16:9，分辨率为1920 x 1080像素，相对于sRGB参考，色彩空间覆盖率达到100%，亮度为350尼特。我们将很快验证这些规格的准确性。该系统的配置成本约为1,200美元，就所安装的硬件而言，这有点儿高了。
LG Gram 15的竞争者包括其他15英寸办公笔记本电脑，其80-EU版本的英特尔 Iris Xe Graphics G7诸如 联想ThinkBook 15 Gen2 ITL, Acer Aspire 5 A515-56-511A和 Honor 魔法书15.除了上述的笔记本电脑，我们还包括了 老款Gram 15在我们的比较表中。

案例
据LG称，机箱由镁合金组成，很容易让人联想到去年的模型，尽管仔细检查后会发现一些差异（如网络摄像头的形式和键盘的字体）。
就像之前的Gram 15一样，我们对机箱的感受不一。虽然该系统重量极轻，只有1.1公斤，并且由于其适度的尺寸（只有17.4毫米厚）而高度便携，但由于其非常薄的表面（触觉更类似于塑料而不是金属），该设备的硬度还有待提高，特别是在施加压力时。
在一些地方，外壳会明显变形。摇摇晃晃的显示屏盖子很容易从角落里扭动。在这里，LG可能在轻薄的兔子洞里走得太远了。同样，在铰链方面也有改进的余地。当笔记本电脑受到震荡时，显示屏往往会摇晃。从审美角度看，机箱看起来非常光滑和有吸引力。建造质量也不值得批评。
连接性
接口
端口的选择与去年的型号相同。除了以太网端口（盒子里有适当的USB-LAN电缆），大多数重要的端口都可用。虽然有两个传统的USB type-A 3.2 Gen 2端口位于右侧，但两个现代的USB4 type-C端口，除了支持Thunderbolt 4，还支持DisplayPort和Power Delivery，占据了左侧边缘。附带的65瓦的充电器也使用了Type-C形式。HDMI输出、音频插孔、microSD读卡器和一个Kensington锁端口完成了端口列表。
由于所有的端口都位于两侧的后半部分，对于选择连接外部指点设备的用户来说，有足够的空间用于鼠标移动。
SD卡阅读器
结合我们的参考卡，上述microSD读卡器的性能只能算是一般。也就是说，如果适用的话，它可以与竞争对手的解决方案相媲美，连续读取速度为90MB/s，传输图片时约为70MB/s。

沟通
由于我们现代化的测试设置，Wi-Fi的数值不能与我们比较中的其他设备直接比较，所以它们的数值没有被发现。结合我们新的参考路由器华硕ROG Rapture GT-AXE11000，集成的英特尔Wi-Fi 6E AX211在发送和接收数据时分别达到了1514 Mb/s和1640 Mb/s的优异速度。
网络摄像头
用户不应该对集成的网络摄像头期望太高。按照惯例，色彩准确性是该解决方案的一个明显弱点（图像看起来比较苍白）。得益于1080p的分辨率，清晰度还算不错。
维护
由于笔记本电脑底部的螺丝隐藏在（粘上的）橡胶脚或盖子下面，而且我们的模型来自一家商店，我们决定不打开箱子。
担保
LG提供24个月的国际保修。
输入设备
键盘
我们对制造商在输入设备上的做法感到满意。就笔记本电脑的标准而言，键盘提供了相当准确和清脆的反馈，并有明显的按键咔哒声。由于键盘背光灯有两个亮度设置，在黑暗中使用笔记本电脑是一种很好的体验。布局可能会有争议。ISO-区域版本仍然使用单行回车键。同样，三栏式数字键盘和相对狭窄的方向键可能会让一些用户感到失望。
触摸板
LG的触摸板使用起来很舒服。尽管机箱的刚性很低，但靠近触摸板底部边缘的按钮提供了一个令人惊讶的明显的启动点，并允许精确的输入。相对光滑的表面提供了良好的滑行性能。同样，手势也得到了很好的支持。触摸板的尺寸为~11 x 7厘米，足够大了。
显示
与前辈不同的是，目前这一代Gram采用了哑光显示屏，这不仅更容易入眼，而且对户外能见度也明显更好。

显示屏的许多方面都比老款的Gram 15要好。这方面的一个例子是亮度，它已经从大约300尼特增加到大约400尼特。再加上较低的黑值（0.32对0.46尼特），对比度几乎翻了一番。1300:1的对比度和95％的sRGB覆盖率应该让大多数用户感到满意。
同样，色彩准确性也令人印象深刻，尽管我们能够通过自己校准显示器来进一步提高delatE值（我们校准的ICC配置文件可在照明图旁边下载）。
由于响应时间一般，60赫兹显示屏的游戏能力有限。同时，该显示屏以典型的IPS视角闪亮登场。在我们测试机型的16:9长宽比和14英寸、16英寸和17英寸机型的16:10面板之间的选择是一个个人偏好的问题。

业绩
按照配置，LG Gram 15是一款中端办公笔记本电脑。虽然CPU的性能足以满足许多使用情况，但iGPU在3D应用中很快就达到了极限。
测试条件
LG的智能助手现在组织得很好，提供了从静音到高的多种冷却模式。我们使用正常设置运行所有的基准测试，这是出厂默认值，除非另有说明。
处理器
LG使用的是酷睿i5-1240P处理器。Alder Lake型号基于10纳米工艺，提供四个带超线程的性能核心和八个不带超线程的效率核心，总共有16个线程。
LG Gram 15限制了CPU的性能。虽然冷系统的结果看起来相当好，但性能随着时间的推移而大量下降，而且--更糟糕的是--然后波动非常大，偶尔会下降到 酷睿i5-1135G7的水平正如我们的Cinebench循环所示。在我们对去年的Gram 15的审查中，Core i7-1165G7 酷睿i7-1165G7也没有发挥出它的全部潜力。
更新：我们运行了第二个 Cinebench循环，冷却曲线为高。在这种情况下，性能下降的幅度要小得多，波动也不那么严重。

系统性能
CPU性能的波动几乎不影响系统性能基准。在PCMark 10中得到4992分，我们的测试设备在我们的比较中排名第一。LG Gram的快速DDR5-RAM可能是一个主要的促成因素。从主观上看，Gram 15的反应速度略逊于类似配置的笔记本电脑。

存储解决方案
存储解决方案遭受了与CPU相同的命运。虽然最初的性能符合我们的预期，有很好的速度，但在很短的时间内，性能就会大幅下降，并开始出现严重的波动，其方式与处理器并无不同。我们已经在许多使用最新PCIe4固态硬盘的笔记本电脑上观察到类似的行为（LG使用1TB的三星PM9A1）。

排放
噪声排放
即使新的LG Gram 15在3D应用中往往比其前辈慢，但噪音和热量排放更高。2022版在负载下产生的噪音不是32dB(A)，而是高达37dB(A)，这让人注意到，但仍然不会让人分心。在空闲时，15英寸系统仍然相当安静，为26至28分贝（A），风扇完全关闭，这取决于系统的负载。
对于特别敏感的用户，静音模式可能是一个明显的选择。然而，就像在Gram 14上一样，不幸的是，性能下降得如此严重，甚至只是播放高清视频也会导致卡顿和冻结。这使得这种模式有些无用，这是一种耻辱。

温度
尽管峰值温度为46°C，但表面从未变得不舒服的热，与格拉姆的竞争对手相比，其数值有所增加。同时，在空闲时情况明显好转。平均23°C左右的温度不值得批评。

压力测试
由于硬件已经在正常应用的极端波动中挣扎，全负荷下的极端节流不应该是一个惊喜。在我们用FurMark和Prime95进行的压力测试中，CPU的时钟速度偶尔会降到1GHz以下，而iGPU可以降到低至100MHz。
发言人
对于像LG Gram这样轻薄的设备，其音频质量令人印象深刻，尽管2.0设置的低音再现当然不那么理想。

电池寿命
最新的Gram 15继承了其前辈的80-Wh电池容量。因此，与42瓦时和49瓦时的竞争对手相比，运行时间明显更长，这不应该是一个惊喜。老款机型的持续时间仍然略长。在最低亮度下高达23小时的空闲运行时间和在中等亮度下近12小时的网络浏览时间仍然是一个令人印象深刻的结果。在负载和最大亮度下，我们的测试设备仍能达到略高于3小时的运行时间。

判决书
对2022年版本的LG Gram 15的评判在很大程度上取决于你的要求。
对于那些追求最大性能和刚性的用户来说，这个系统可能是一个次优选择。这款笔记本电脑在压力下明显会出现问题，而且有明显的性能波动--这适用于CPU、iGPU和SSD。
LG Gram 15对于那些正在寻找一个具有轻量级机箱和长电池寿命的系统的用户来说是一个不错的选择，可用于要求不高的工作负荷，如办公任务和视频流或网络浏览。
这款15英寸的系统在这三个方面几乎无可匹敌，使其成为一个非常适合旅行的伙伴，由于其（最终）哑光屏幕和高最大亮度，不必回避户外使用。
这款 Honor 魔法书15是一个潜在的替代品，它的重量稍高，电池寿命较弱，但也有一个更坚固的底盘和更稳定的性能作为交换。
价格和可用性
LG Gram 15Z90Q可从各种在线商店购买，如亚马逊价格约为1,445美元。
