LG Gram 14 (2022)笔记本电脑回顾。时尚、轻巧、经济
去年的 2021年模型基于 酷睿i7-1165G7在我们的审查中获得了88%的优秀分数。现在,LG已经发布了它有希望的继任者。主要的区别和改进是哑光显示屏,仍然使用16:10的长宽比,分辨率为1920 x 1200像素(仍然只有60赫兹)。至少在纸面上,CPU的升级看起来也是巨大的。2022年的机型没有使用四核英特尔Tiger Lake 芯片,而是使用12核英特尔Alder Lake 酷睿i5-1240P.Gram 14Z90Q的其余规格则不那么有趣。16GB内存和512GB NVMe固态硬盘在1000美元的价位上同样是标准配置(该设备起价约1080美元)。最后,Windows 11 Home是首选的操作系统。
Gram 14的竞争者包括其他重量低于1.5公斤(约3.3磅)的14英寸笔记本电脑,如 戴尔Latitude 7420或联想 Yoga Slim 7i Pro 14和 IdeaPad 5 Pro 14.我们还包括去年的型号,以便进行比较。

案例
从外观上看,外壳没有什么变化。然而,LG现在使用更精致的字体来显示按键图例,并在机箱背面使用橡胶条而不是圆形橡胶脚,以提高稳定性。新机箱的制造质量很好。虽然根据制造商的说法,其表面由镁合金组成,感觉更像是塑料而不是金属,但Gram 14看起来相当高档。
也就是说,用户不应期望在刚性方面有太多的表现。在适度的压力下,键盘中心和触摸板区域都会有明显的弯曲。同样,盖子对来自角落的扭曲尝试的抵抗力也不是很强。不管怎么说,大多数用户还是应该认为对于这么薄的笔记本电脑来说,其刚性还是可以接受的。Gram 14的设计不值得批评。薄的外观(高度只有16.8毫米或约0.62英寸)、小边框、果断的设计语言和白色的配色方案使这款14英寸的设备非常有吸引力。
低重量是LG Gram的最大优势。980克(约2.16磅)使得设备非常轻便,这使得其竞争对手在1.3-1.4公斤(约2.87-3.09磅)时显得过时和沉重。几乎没有任何笔记本电脑能像Gram 14那样便携。
连接性
端口
端口的选择与前一型号的类似。虽然一个音频插孔、一个HDMI输出(未指定版本)和两个带Power Delivery和DisplayPort或Thunderbolt 4的USB 4 type-C端口占据了左侧,但一个microSD读卡器、两个传统USB 3.2 type-A端口和一个Kensington锁位于右侧。由于两侧的端口都靠近背部,在使用外部鼠标时应该不会有干扰性电缆。
SD卡阅读器
读卡器的性能相当平均。在传输照片时,几乎是70MB/s,人们可能会将我们的测试设备与联想IdeaPad 5 Pro 14混淆。只有戴尔Latitude 7420能够明显超过其同行(近200MB/s)。

沟通
一个英特尔模块处理无线网络。结合我们新的华硕参考路由器(我们没有竞争对手的结果),Wi-Fi 6E AX211达到了一个很好的范围。从1米(约3.28英尺)的距离接收数据时,1700Mb/s的传输率不值得批评。

网络摄像头
不幸的是,该网络摄像头并不像全高清分辨率所显示的那样好。虽然较高的分辨率导致与许多竞争对手相比清晰度稍好,但就图像质量而言,它总体上是不够的(例如,由于色彩准确性差)。
辅料
除了一些文件之外,笔记本电脑还配备了一个65瓦的充电器,它不仅非常紧凑(~9.5 x 6 x 2.5厘米/~3.74 x 2.36 x 0.98英寸),重量轻(~230克/~0.51磅),而且圆润漂亮,与白色机箱相匹配。
维护
由于底板上的螺丝隐藏在(胶合)橡胶部件下面,我们决定不打开设备(设备由商店提供)。YouTube上有拆解视频,其中显示了Gram 14的内部结构。
输入设备
键盘
鉴于其薄的结构,键盘的感觉出奇地好。与其他14英寸笔记本电脑相比,反馈和启动点分别清晰明了,而按键的响声可能相对较大。在正常的打字过程中,键盘几乎不产生变化。不一定要在图书馆等安静环境中打字的人,应该会对Gram 14感到满意。然而,在布局方面还有改进的余地。即使在ISO地区的机型上也有ANSI布局的回车键,而ISO地区的机型也有一个分体式的左移键。此外,将插入/删除和电源键合并在一起作为主键行的一部分是不太理想的。同时,狭窄的方向键不幸出现在许多其他笔记本电脑上。
当然,Gram 14的键盘还包括一个有两个亮度级别的背光。根据一天中的时间、观察角度和环境光线条件,白色按键和白色背光的组合会使按键的图例更难看。在这里,黑键或不同的背光颜色可能会更好。
触摸板
谈到触摸板,没有真正的惊喜--这是件好事。约11 x 7厘米(约4.33 x 2.76英寸),对于14英寸笔记本电脑来说,它足够大了。由于表面光滑,它提供了良好的滑行性能,同时使用起来也很舒适。键盘下半部分的集成按钮提供了适度的触觉反馈。与键盘类似,按键的咔哒声绝对是明显的。此外,点击板在四角附近可以更硬一些,在那里它可以被相对地推入机箱。支持的多点触摸手势在大多数时候都能可靠地工作。我们也没有发现输入的精确性问题。
显示
在显示屏方面,LG再次使用了自己的一个型号。无论是专业用户还是户外爱好者,都应该对LG用哑光版取代老款机型的光面面板的决定感到满意。

虽然305尼特的平均亮度与前代产品(332尼特)相比略低,但在许多情况下,屏幕内容明显更容易辨别,眼睛疲劳也减少了。同样,稍低的对比度(1312:1对1600:1)和稍差的黑值(0.26对0.22尼特)可能会被大多数用户看作是对非光面的值得的权衡。
在其他方面,这两块面板的表现相当相似,考虑到它们相似的ID(LP140WU1),这可能不是一个巧合。100%的DCI-P3色彩空间覆盖率和色彩准确度在出厂时都非常好,只有微弱的蓝色调(我们校准的ICC文件可在照度图的右边下载)。
该显示器的响应时间不太令人印象深刻。差不多25到48毫秒代表了一个相对较差的数值,对于游戏来说并不理想。在这里,一些竞争性的14英寸笔记本电脑(如联想的设备)表现更好。我们还希望下一代的显示屏能有略高的最大亮度,达到400尼特或更高,因为一些竞争对手已经能够达到这个数值。由于采用了底层IPS技术,LG Gram 14的可视角度很好。我们没有发现PWM闪烁或类似问题。

业绩
就性能而言,LG Gram 14是一款中档设备。制造商使用了均衡的组件组合,这--在游戏和其他3D应用之外--使超极本相当灵活。
测试条件
预装的、组织良好的智能助手包含各种系统设置。大多数重要的设置都可以直接在第一个菜单中找到。散热曲线在很大程度上影响了性能和噪音特性。除非另有说明,我们使用默认设置正常进行了以下所有的基准测试。
散热情况 | 静音 | 低 | 正常 | 高 |
CPU PL1 (HWiNFO) | 8瓦 | 12瓦 | 24瓦 | 28瓦 |
CPU PL2 (HWiNFO) | 43 watts | 43 watts | 43 watts | 43 watts |
处理器
在使用正常模式时,CPU的性能令人失望。即使酷睿i5-1240P在名义上比老款的酷睿i5-1165G7快得多,其基准测试结果也只是略高。这非常令人惊讶,因为Alder Lake模型将第11代CPU的8个线程增加了一倍(4个性能核心支持超线程)。
为了获得明显更好的结果,必须将Gram 14设置为热配置文件 "高",这将极大地提高性能。在Cinebench R15多线程中,1500分而不是950分代表了几乎60%的改进。然而,这仍然使Gram 14落后于配备相同CPU的联想Yoga Slim 7i Pro。看来Gram 14的冷却解决方案在Core i5-1240P上已经达到极限。

DPC延时
竞争对手和LG Gram 14都存在不理想的延迟。根据LatencyMon,该系统似乎不大适合实时音频和视频编辑。

存储解决方案
只要固态硬盘不持续受压(在长时间的测试中出现了较大的波动),安装的512-GB三星硬盘表现良好。在这个类别中,根据我们的性能评级,LG Gram 14是我们比较中最快的设备。在DiskSpd基准测试中,去年型号的SK海力士SSD明显落后。

GPU性能
这款14英寸的笔记本电脑必须在没有dGPU的情况下进行。由于 Iris Xe Graphics G7的Iris Xe Graphics G7只有80个EUs,而老款的Core i5-1165G7则没有。 Iris Xe的96个EUs,因此GPU基准测试得分略低。在3DMark基准测试中,前者的GPU性能平均快40%左右。尽管被限制在相同的EU数,联想Yoga Slim 7i Pro也更快(约15%),这反映出Gram 14的冷却解决方案和性能管理不佳。

游戏性能
游戏基准测试描绘了类似的画面。我们的14英寸笔记本电脑不仅与它的前辈和联想设备相比有差距,3D性能也有波动,因为我们的我们的Witcher 3循环测试显示(见图)。总的来说,80-EU版本的Iris Xe Graphics G7只适合在较低的设置和分辨率下用于旧的和/或要求不高的游戏。即使在最低或中等细节下,现代游戏也很少能在1920 x 1200的原始分辨率下播放。

排放
系统噪音
系统噪音的结果是好坏参半。尽管Gram 14在使用 "低 "散热模式时保持相当安静,但在使用 "正常 "模式时,即使在简单的任务中,如视频流或网络浏览,风扇偶尔也会变得很明显(以下数值是在这种模式下测量的)。在35至36 dB(A)的情况下,风扇在负载下明显引人注目(尤其是风扇的噪音相当高),并超过了前代产品的31 dB(A)峰值。
对于对噪音敏感的用户来说,静音模式是最理想的,因为其描述非常准确。不幸的是,性能上的缺陷是如此之大(处理器在一段时间后会节流到400MHz),以至于系统每次都会挂掉几秒钟,视频也会出现卡顿或冻结。在这里,LG仍有一些工作要做。无法使用的静音模式是我们对该设备的最大问题之一。如果没有这个问题,Gram 14本可以成为静音系统爱好者的一个好选择。

压力测试
虽然在我们用FurMark和Prime95进行的60分钟压力测试中,CPU和iGPU都不得不大幅降低其时钟速度,但Core i5-1240P在70°C(158°F)左右时并没有变得非常热。
发言人
2.0设置听起来很好,甚至比其他大多数笔记本电脑更好--不管是什么类别和外形因素。像往常一样,在涉及到低音的时候,也有弱点。这台14英寸笔记本电脑的最大音量为85 dB(A),很扎实。

电池寿命
除了重量低之外,长的电池寿命是Gram的最大优势之一。尽管最新的Gram 14不能像其前辈那样持续很长时间,但在理想条件下(最低亮度,禁用Wi-Fi,空闲)长达29小时仍是一个出色的结果。即使在中等亮度下浏览网页,这款14英寸超极本也能持续12个小时,非常值得称赞。

判决书
Gram 14的2022年型号再次成为一款伟大的14英寸笔记本电脑。
这款轻巧的设备在大多数类别中都取得了良好到优秀的成绩,如外壳、输入设备、声音或排放。特别是哑光显示屏是一个改进,尽管其特性在其他方面与去年的型号的面板相似。
相比之下,GPU性能和噪音排放则是一种退步。尽管Gram 14几乎没有任何速度,有时甚至比它的前辈更慢(因为 酷睿i5-1240P的性能潜力是有限的),风扇噪音在较新的模型上更明显。不幸的是,由于极度的性能缺陷,静音模式无法使用。
虽然这听起来像是很多批评,但与竞争对手相比,Gram 14的表现非常好。几乎没有任何设备能够将这么长的电池寿命与高度便携的机箱结合起来。
这款笔记本电脑适合重视体力而非性能的用户。
的 瑜伽瘦身7i Pro 14是一个潜在的替代品。
