LG Gram 15（2021年）--1.1公斤（约2.4磅）的超轻笔记本电脑，配备80瓦时电池

LG的Gram系列由世界上最轻的笔记本电脑组成，每一种屏幕尺寸都有。LG提供以下尺寸的Gram笔记本电脑。14英寸，15英寸，16英寸和17英寸。在这里，我们有一个15英寸的模型。我们已经审查了其他型号。

前身。

LG Gram 15 15Z90N(2020)

LG集中所有精力制造世界上最轻的15英寸笔记本电脑，并在此方面取得了成功。三星的Galaxy Book Ion Aura Silver是最接近的竞争者，重量仅为1.3公斤（约2.87磅）。这款微星Summit B15 A11M和 Honor MagicBook 15是普通的15英寸笔记本电脑，重量约为1.5公斤（约3.31磅）。

为了减少400克（约0.88磅），LG牺牲了什么？硬度、电池寿命？2021年的Gram 15在内部和外部都进行了重新设计。与2020年基于Ice Lake 的Gram 15相比，其设计、端口的选择和内部布局都发生了变化。

案例："僵硬 "并不能说明LG笔记本电脑的情况

2021年的克15（1.107公斤/~2.440磅）比2020年的克15（1.093公斤/~2.410磅）重了几克。这并不是由于材料的改变，因为两款笔记本电脑的外壳仍然是由镁制成的。这里只有点缀着钥匙孔的顶盖提供了刚性，因为底盖极薄且可弯曲。铰链和所有部件都连接在顶盖上。

如上所述，底盖非常薄且易碎，但它（在螺丝的帮助下）牢牢地连接在顶盖上。总而言之，当你把它拿在手里时，这台笔记本电脑给人的印象是好坏参半。一方面，对于这样一个轻型设备来说，它感觉相当硬。另一方面，铝制外壳的笔记本电脑感觉更结实、更高档，但重量更大。这并不令人惊讶，毕竟，用镁制造一个感觉僵硬的轻巧设备几乎是不可能的。

有趣的是，LG不得不采用一种框架来固定电池，并确保它不会扭动得太厉害。

显示屏的盖子也真的很灵活。然而，这似乎不会对内置的IPS面板造成任何问题，因为它是直接与显示屏盖子耦合的。在过去，制造商试图避免这样做，因为这曾经导致视觉伪影，有时还会导致损坏。然而，现在除了打开盖子时，没有任何视觉伪影。

LG使设计更有棱角，这在看底盖时也很明显。现在还多了几颗螺丝。

在重量方面，Gram 15远远领先于竞争对手。比如说三星Galaxy Book Ion比它重200克（约0.44磅），但它也是由镁制成的，感觉很松散。更重的15英寸笔记本电脑，如峰会B15，感觉很硬，但其外壳是由铝制成的。

网络摄像机

网络摄像头有一个0.9百万像素（1280x720）的传感器，能产生冲淡和模糊的图像。在弱光环境下，也有一大堆噪音。图像质量处于非常低的水平，这也是当今笔记本电脑摄像头的特点。Gram 15的网络摄像头的色彩表现特别差。在这里，更便宜的Honor MagicBook要好得多。

安全问题

Gram 15有一个Kensignton锁和一个指纹传感器，它被整合到电源按钮中。

辅料

除了常见的保修和安全手册外，Gram 15的包装盒里还有一个65瓦的电源适配器。这次没有以太网适配器。

维护

Gram 15不再有任何内存插槽，这意味着内存是不可扩展/可更换的。Wi-Fi模块也是焊接而成的。在2020年，情况也是如此。但仍然有两个M.2（88毫米）插槽，其中一个是空的，这意味着用户仍然可以轻松地安装另一个固态硬盘。电池可以更换，因为它只是用螺丝固定。

拆卸很简单：只需取下塑料脚，解开螺丝，用吉他挑子或spudger取下底盖。底板可以被卸下，而不会在设备上留下任何划痕或擦痕。

担保

LG Gram 15有24个月的保修期（包括在德国和其他国家）。

输入设备。带数字键盘的Gram 15

Gram 15应该是一个工作设备，这就是为什么它有一个带数字键盘的键盘。布局没有改变，但功能键的颜色从橙色变成了白色。这就是为什么功能键不再那么显眼了。

键盘

按键感觉稳定，并提供良好的触觉反馈。启动点很清晰，而且按键的移动距离也很合适。打字时，键盘面板表现出一些弯曲。

键的间距很好，比通常的笔记本电脑键大一毫米左右。然而，数字键盘的按键很小。此外，数字键盘没有 "加"、"减 "和 "回车 "等键。

触摸板

触摸板的尺寸为11.1x6.9厘米（4.37x2.72英寸）。触摸板运行良好。它对输入的反应迅速而可靠。底部有两个物理按钮，有一个非常清晰的启动点，并提供非常好的触觉反馈。

显示屏。LG面板具有高反射率的表面

Gram 15采用全高清15.6英寸面板，像素密度为144PPI。这块IPS面板是由LG Display制造的。我们测量的峰值亮度为310cd/m²，这是一个相当不错的结果。三星Galaxy Book Ion的显示屏达到了467 cd/m²的亮度。在电池供电时，亮度下降到299 cd/m²。

由于黑值不高（0.46 cd/m²），对比度也相当差（746:1）。前代机型（1307:1）和Gram 16（1505:1）的屏幕对比度明显更好。Gram 15的屏幕不存在屏幕出血和PWM闪烁的问题。

* ... smaller is better

LG宣称，该显示屏可以覆盖99%的sRGB。然而，我们的测量结果显示，IPS面板只能覆盖92%的sRGB。P3（62%）和AdobeRGB（64%）的覆盖率也不完整。Gram 16在这个领域做得更好。这很可能是LG没有将Gram 15的种子提供给评审员的原因之一。

我们使用Calman软件和分光光度计来确定显示器的色彩准确性。刚开箱时，灰度表现不是特别好（这里的DeltaE高于4）。此外，对于训练有素的眼睛来说，颜色看起来并不十分正确。然而，在校准的帮助下，色彩再现可以得到改善。你可以通过包含所有显示器测量值的盒子底部的链接下载我们为LG Display LP156WFC-SPY1设计的色彩配置文件。

我们的校准显著改善了色彩再现。校准后，DeltaE从3.5下降到1.2。

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
18 ms ... rise ↗ and fall ↘ combined	↗ 8 ms rise
18 ms ... rise ↗ and fall ↘ combined	↘ 10 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. » 36 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined	↗ 18 ms rise
36 ms ... rise ↗ and fall ↘ combined	↘ 18 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. » 46 % of all devices are better. This means that the measured response time is similar to 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 not detected

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.

光滑的面板不适合在户外使用，特别是考虑到电池供电时的亮度约为300cd/m²。这限制了Gram 15在旅途中的可用性。

IPS面板的可视角度非常好。亮度只在极端角度下下降。锐角下的色彩准确性也较差。

性能。在短期工作负荷中表现良好

Tiger Lake 基于酷睿i7-1165G7的英特尔Iris Xe图形（96EUs）。

2021年的Gram 15有两种配置：一种是采用酷睿i7-1165G7(4 x 2.8 - 4.7 GHz)，另一个配置为酷睿i5-1135G7(所谓的商务版)。两种型号都有16GB的内存。然而，酷睿i5变体有一个512GB的固态硬盘，而酷睿i7型号则有一个1TB的固态硬盘。这些都是相当高端的配置，这反映在1150欧元（约1280美元）至1600欧元（约1780美元）的价格上。

系统设置

在进行任何基准测试之前，我们下载并安装了最新的BIOS和Windows更新。我们在GPU和CPU基准测试中使用了 "最佳性能 "的电源模式。对于我们的电池测试（Wi-Fi/空闲），我们使用了 "最佳电源效率 "电源模式，该模式现在在Windows 11中可用。新的省电模式禁用了通知并限制了后台任务，这意味着One Drive等应用程序在这种模式下不会不断刷新。

处理器

芯片酷睿i7-1165G7(Tiger Lake, UP3) 是最快的28W CPU之一。它的TDP可以从12到28W不等。LG将功率级别一（PL1）设置为25W，这就是我们在测试中看到的情况。然而，该CPU只能在短时间内保持这一功率水平。总而言之，这些功率水平使应用程序能够快速启动，系统在日常使用中感觉非常灵敏。

不过，Gram 15的GPU并不适合持续负载。在我们的Cinebench 15循环中，功耗在片刻间达到40瓦的峰值，然后降至约20瓦。在全负荷下，功耗在10至20瓦之间波动，罕见的峰值为25瓦。

总而言之，LG Gram 15中的Core i7-1165G7的性能比一般的Core i7-1165G7差28%。这似乎是LG笔记本电脑的普遍特点。Gram 16的CPU性能也不尽如人意，但性能水平并没有偏离常规那么多。

将Gram 15与竞争对手进行比较时，我们看到三星Galaxy Book Ion Aura Silver与较老的酷睿i7-10510U在负载下表现得更好。微星Summit B15，拥有更强大的冷却解决方案和更高的PL1和PL2，显示了Core i7-1165G7的能力。例如，微星Summit B15在负载下比Gram 15快40%。

因此，在Cinebench R20和R23中，Gram 15被配备Core i5-1135G7和Core i7-1165G7的笔记本电脑击败，这并不令人惊讶。Gram 15在AIDA基准测试中也表现不佳。

系统性能

在PCMark 10基准测试中，鉴于Gram 15在CPU基准测试中表现不佳，它的表现比预期要好。我们的LG样品在我们的比较图表的顶部附近占据了一个位置，并成功地超过了MSI Summit B15.AIDA内存基准测试证实，我们的评测设备在复制和写入数据方面领先于竞争对手。事实上，它还击败了Gram 16。不过，在涉及到内存延迟时，竞争对手是领先的。

DPC延迟

说到DPC延迟，Gram 15的表现不是特别好。即使有几个打开的浏览器标签，我们也看到了延迟的峰值。然而，在YouTube的测试中没有问题（只有3个丢帧）。在测试中，我们使用了微软的Edge浏览器的默认设置。我们还使用了 "最佳性能 "的电源模式。这里的主要问题在于ACPI驱动程序。16英寸机型没有这些问题（420对1662微秒）。这有可能只是我们特定评测设备特有的一次性问题。我们的DPC测试是在我们审查时使用最新的可用驱动程序进行的。

存储设备

一块1TB的SK海力士固态硬盘被安装在一个M.2插槽中。另一块SSD可以安装在第二个M.2插槽中，该插槽是空的。用户可以获得815GB的存储空间。固态硬盘的性能优于平均水平，这可能是我们在PCMark 10中获得非常好分数的原因。的LG Gram 16 (2021)没有相同的SK海力士固态硬盘，但在存储基准方面的表现仍然非常相似。

Witcher 3 展示了CPU和GPU是如何争夺非常有限的功率预算的。最后，CPU占了上风，但它只消耗了10到20瓦，并且只在700兆赫下运行。这与CPU的全部潜力相差甚远。简而言之，集成GPU在游戏时非常吃力。英特尔的Iris Xe GPU即使在最好的情况下也不是一个好的执行者，但在这里它的表现特别差。

排放。Gram 15保持安静和凉爽

系统噪音

Gram 15是一台安静的笔记本电脑。风扇很少启动，而风扇的噪音从未超过32 dB(A)。笔记本保持非常安静，因为它在连续负载下会节流。在这里，LG选择了低噪音水平而不是性能。笔记本 Galaxy Book Ion Aura的噪音略大，但它在负载下没有节流。不过，在空闲时，两款笔记本都是绝对安静的。

温度

单一的风扇和小的热管可能是Gram 15在负载下节流的原因。但这是每个LG Gram笔记本电脑的情况。在任何情况下，这样的铜热管通常重约100克（约0.22磅）。

闲置时，目前的英特尔芯片很难被打败。在这里，电力消耗，在大多数情况下，从2.9W到8.7W不等。这就是为什么笔记本电脑感觉很酷。在负载情况下，情况看起来完全不同，但即使在这里，表面温度也不会很严重（在键盘的上部约为40℃/104°F）。底部从未变热（甚至比顶部更凉）。我们看到，LG采用了适度的冷却解决方案。然而，为了防止笔记本过热和产生大量噪音，LG决定设置低功率限制。对于一个超移动设备来说，这并不是一个不合理的妥协。

压力测试

在Prime95和Furmark的帮助下进行的压力测试中，我们记录了SoC的温度、时钟和功率消耗。短暂的55W峰值是值得注意的。在这里，我们看到CPU温度峰值为85℃（185°F），CPU时钟从3.5GHz降至1.6GHz。因为在压力测试期间，系统始终处于负载状态，内部温度保持在80°C（176°F）以上，直到CPU时钟速率下降到1.1GHz。在这之后，CPU温度下降到70 °C（158 °F）以下。但随后，时钟频率又开始上升，直到核心温度达到78℃（172.4°F），时钟速度再次下降。这个周期一再重复，也就是说，只要核心温度降到70℃（158°F）以下，CPU频率就开始上升。然而，只要CPU温度达到78℃（172.4°F），工作频率就会下降。

两个扬声器位于腕托下方（靠近两侧）。当笔记本电脑放置在一个均匀、坚固的表面上时，扬声器的性能最好，从这个表面上可以很容易地反射声音。小驱动器的设计已经改变，但大的腔体仍然保留。

我们并没有期待有什么奇迹。笔记本电脑的扬声器听起来很尖锐，低音也非常小。这里没有任何一代的改进。值得注意的是。即使扬声器格栅被覆盖，也没有真正的音量损失，只有声音特征发生了一些变化。这是由于笔记本内部的谐振室造成的。与其他15英寸笔记本电脑相比，音量在一个合适的水平上。声音在全音量时不会变得失真。

Gram 15配备了讯连科技的音频总监7。它不是最强大的音频编辑程序，但它至少是个东西。双麦克风阵列即使在离设备0.5到2米的地方也能产生无噪音的录音。

能源管理。Gram笔记本电脑的电池寿命为14小时

能源消耗

与前代产品相比，耗电量没有明显变化。LG Gram 15在空闲时的功耗为2.9至11.5瓦。在负载情况下，系统的功耗为29W，比基于Ice Lake 的前代产品低2W。鉴于在我们的压力测试中，耗电量仅在64W徘徊了几秒钟，65W的电源适配器应该不难为设备提供足够的能量。

我们用外部显示器和内置显示器来测量系统功耗。在这里，即使在峰值测量中也没有太大的差别。在压力测试的前三分钟后，功耗从60瓦下降到35-25瓦。其他笔记本电脑没有节流这么多。例如，配备MX250的三星Galaxy Book Ion Aura Silver在我们的压力测试中成功保持了高水平的性能。

电池寿命

LG Gram 15配备了80瓦时的大电池，这是值得注意的，因为较小的电池通常重量较轻。在这里，LG使用了能量密度很高的电池。顺便说一下，所有LG Grams都使用这种电池，甚至17英寸的也是如此。

在我们的Wi-Fi测试中，我们将亮度设置为150cd/m²并启用通信模块，Gram 15持续了近14个小时（比Gram 16少两个小时）。竞争对手的笔记本没有机会对抗Gram 15，因为它们配备的电池较小。

LG Grams持续如此之久的另一个原因是节流。值得再次提及的是，CPU的功耗在负载下在10至20瓦之间波动。

在闲置电池测试中，通信模块被禁用，亮度降低到22cd/m²，笔记本电脑持续了令人印象深刻的26小时。然而，这项测试与日常使用的关系不大。

结论。Gram 15提供了很好的电池寿命，但性能不高

2021年的Gram 15在性能上比2020年的Gram 15有了相当大的提高，后者是基于Ice Lake CPU。此外，2021年的模型得到了视觉上的重新设计。低重量仍然是该笔记本电脑的主要特点。它比所有其他竞争的15英寸笔记本都要轻，而且还提供出色的电池寿命（我们在这里说的是14小时）。

LG未能充分释放酷睿i7处理器的潜力。在这种特殊情况下，我们看到40%的性能不足。尽管如此，由于快速的固态硬盘和40W的突发TDP，系统感觉很灵敏。Gram 15并不适合重度、连续的负载，但它在所有其他情况下运行良好。

非常低的重量是LG Gram 15的与众不同之处。为了启动，LG的笔记本电脑还提供了出色的电池运行时间（14小时）。

我们没有处理过酷睿i5版本的Gram 15，但我们估计它的性能应该不会比酷睿i7模型差很多，这就是为什么我们建议获得酷睿i5变体。它提供的存储空间较少，但内部存储可以通过安装额外的固态硬盘轻松扩展。该设备内部有一个空的M.2-2280插槽。

对那些重量不是很重要的人来说，可以获得三星Galaxy Book Ion Aura Silver它的价格要低50%，重量只多200克（约0.44磅）。然而，使用Galaxy Book Ion，你只能得到一半的电池寿命（7小时）。

价格和可用性

配备酷睿i5-1135G7和512GB固态硬盘的LG Gram 15可以在亚马逊上购买。售价1249.99美元。
