LG Gram 14T90P敞篷车回顾。联想Yoga和惠普Spectre的挑战者
16:10的LG Gram 14T90P继承了老一代的16:9 Gram 14T90N通过引入更快的英特尔第11代处理器选项和新的机箱设计，成为一个完整的系列更新。与所有其他Gram型号一样，Gram 14T90P旨在最大限度地提高显示质量，同时最大限度地减轻重量，成为其尺寸类别中最轻的Core U系列笔记本电脑之一。
我们的评测单位已经配置了酷睿i5-1135G7处理器，16GB焊接内存，512GB NVMe固态硬盘，以及14英寸1200p IPS触摸屏，零售价约为1000至1100美元。其他SKU可以用酷睿i7-1165G7代替，但都配有相同的1200p面板。
这个领域的直接竞争对手包括其他高端次笔记本转换器，如 华硕Zenbook Flip 14, 惠普Spectre x360 14, 戴尔XPS 13 2合1, 微星峰会E13翻转, 或 联想Yoga 9 14.

案例--从旧的设计中大幅升级
机箱设计基本上是最近的16英寸格拉姆的小型化版本。 16T90P.它可能不像戴尔XPS、惠普Spectre或华硕Zenbook系列那样具有视觉冲击力，但它通过更轻和通过MIL-STD 810G规格认证来弥补这一点。它的底座和盖子也比老式的Gram 14T90N更坚固，扭动最小，没有吱吱作响，不容易弯曲或损坏，比起 三星Galaxy Book Pro 360系列.
尺寸与之前的Gram 14T90N略有不同，但总体体积和重量几乎相同。因此，用户获得了一个更大的16:10触摸屏，而不需要一个更大或更重的机箱。该系统比大多数竞争性敞篷车要轻约100克至200克，这在操作或旅行时是很明显的。

连接性 - 2x Thunderbolt 4
端口选项与较大的格拉姆16T90P相同。格兰14T90P取消了格兰14Z90P或格兰14T90N上的HDMI端口和Kensington锁插槽，同时提供比14Z90P更少的选项。例如，只有一个全尺寸的USB-A端口，而不是两个，这意味着鼓励用户利用USB-C配件或扩展坞来代替。
按下右侧边缘的按钮可以打开或关闭显示器。这是一个奇怪的功能，我们在许多其他转换设备上没有看到，而且不幸的是，它不是用户可定制的。
SD卡阅读器
从弹簧式MicroSD读卡器的传输速率平均在85MB/s左右。将1GB的图片从我们的UHS-II卡上移到桌面上，大约需要15秒，与迄今为止的所有其他克拉克机型相似。

维护
与迄今为止的其他每一台格拉姆笔记本电脑一样，底板被设计成非常难以打开，因为螺丝被隐藏在贴纸和橡胶脚下。这是一个耻辱，因为该系统可以支持多达两个内部M.2 2280固态硬盘，而不是一个额外的存储空间，但LG已经让业主恼火地难以添加自己的驱动器。
内存和WLAN都是焊接的，用户无法升级。
由于我们无法在不损坏的情况下打开我们的测试设备，我们可以参考FCC的官方图片。.
配件和保修
零售盒包括一支Wacom主动式手写笔以及通常的文件和AC适配器。标准的一年有限保修期适用。
输入设备 - 伟大的键盘，糟糕的点击板
键盘
与大多数其他超极本相比，键盘按键的反馈明显更坚硬，更不像海绵状。如果你习惯于在较软的键盘上打字，如华硕Vivobook、惠普Pavilion 、联想IdeaPad，甚至是Razer Blade，那么你会对Gram 14T90P上的按键有多硬感到惊讶。然而，更坚硬的按键带来的后果是比平均水平更响亮的敲击声，使打字体验略显嘈杂。
触摸板
与键盘相比，我们对点击板的印象不深。虽然它比Gram 14T90N上的点击板要大（11.3 x 7厘米，10.5 x 6.5厘米），可以更容易地进行光标控制和多点触摸输入，但点击的反馈太过柔和安静。更有力的反馈会使人感到更满意。
显示屏 - 锐利，颜色出色
LG Gram 14T90P使用相同的高品质的LG飞利浦LP140WU1-SPA1 IPS面板，因为发现在 格兰14Z90P.因此，色彩再现、响应时间和对比度等属性在它们之间基本相同，可以获得非常相似的观看体验。
与Gram 14T90N的显示屏相比，我们的Gram 14T90P提供了更深的色彩和稍快的黑白灰响应时间，而不影响亮度或对比度。即便如此，我们还是希望在未来看到OLED和/或90赫兹面板，因为这样的功能正在成为高端次笔记本的标准，比如竞争者的华硕Zenbook Flip 14.

LG宣传DCI-P3的覆盖率为99%，我们可以用我们自己的X-Rite色度计确认这一点。奇怪的是，计算AdobeRGB的结果是有误差的，但覆盖率应该是非常相似的，约为99%。这是为数不多的14英寸16:10 IPS面板，提供与大多数OLED面板相似的色域。
这款显示器开箱后的校准效果不错。平均灰度和ColorChecker DeltaE值分别为1.9和3.31。
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 | ||

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 78 % of all devices are better.

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 8710 (minimum: 5 - maximum: 343500) Hz was measured. | |||
在300尼特的情况下，显示屏的亮度对于室内条件来说是足够的，但对于户外的舒适观看来说，还没有达到需要的程度。替代产品如戴尔XPS 13 9310二合一或微星Summit E13 Flip的显示屏要亮得多，每个都超过500尼特，在户外更容易观看。
性能 - 第11代英特尔
测试条件
在运行任何性能基准测试之前，我们的设备被设置为性能模式，以获得尽可能高的分数。强烈建议熟悉预装的LG控制中心软件，因为关键设置和功能在这里切换，如下图所示。令人讨厌的是，该软件的用户界面非常小，而且不能被最大化。
请注意，每次重启或关机后，系统会自动重置为平衡模式，即使事先将电源配置文件设置为静音或性能。
处理器
CPU性能在我们数据库中配备相同的笔记本电脑的几个百分点之内。 酷睿i5-1135G7处理器。因此，性能并没有因为要适应超轻的可折叠机箱设计而被扼杀太多。升级到 酷睿i7-1165G7SKU有可能将多线程性能提高25%，但可能会少得多，因为我们配置中的Core i5已经可以达到90℃以上的温度。
Turbo Boost的可持续性很好，但并不完美。当循环运行CineBench R15 xT时，我们最初的796分最终会下降并稳定在大约666分，表示由于热限制，性能随时间下降了16%。这两台 戴尔Latitude 14和Acer Swift 3 SF314都能够持续更快地运行相同的处理器，正如我们下面的对比图所示。

GPU性能
集成的图形性能来自 Iris Xe 80 EUs是优秀的，比配备相同GPU的大多数其他笔记本电脑更快。当与更常见的Core i7 Iris Xe 96 EUs，我们的酷睿i5 Iris Xe 80 EUs可能会慢15%到30%左右。这仍然是一个显著的升级，从 UHD Graphics 620不过，与老式的Gram 14T90N上的620相比，仍然是一个重大的升级。
不幸的是，性能并不像我们希望的那样稳定。当空转时 Witcher 3例如，在低720p设置下，帧率会在75和85FPS之间波动，而不是像大多数其他笔记本电脑那样一直保持稳定。连续两次运行Fire Strike ，也会导致相对较大的物理分数差异（10017分对11226分）。我们建议启用vsync来限制屏幕撕裂和不稳定的帧时间。

系统噪音 - 在大多数情况下都很安静
风扇噪音行为与我们在Gram 14T90N上观察到的类似，后者已经是一台相对安静的机器。我们能够测量到只有28.3 dB(A)，即使在运行3DMark 06的第一个基准场景后，也比戴尔XPS 13更安静。 联想Yoga 9 14和华硕ZenBook Flip 14在类似条件下的噪音。在游戏或CPU处于100%利用率的情况下，风扇噪音似乎达到了35 dB(A)。

温度
在运行低负载时，表面温度比我们在竞争产品联想Yoga 9 14IAP7上观察到的要低，而在运行更高的负载时，它们之间的温度是差不多的。热点是离键盘中心最近的地方，它可以达到40摄氏度，与格力14T90N或上述联想的温度相当。

压力测试
当在Prime95下受压时，CPU会在几秒钟内提升到3.5 GHz和95 C，然后稳步下降，最终稳定在2.1 GHz和73 C。我们怀疑处理器不会稳定在更高的时钟速率，以保持皮肤温度。在测试开始时，CPU的TDP会高达47W，然后再稳定在只有18W的结果。相比之下，在惠普Spectre x360 14上运行这个相同的测试 HP Spectre x360 14进行同样的测试，酷睿i7-1165G7将导致循环的CPU时钟速率和温度分别为2.1 - 3.4 GHz和75 - 95 C，平均性能更高。
在性能模式下运行会导致更高的时钟速率和温度，正如我们的图表和下表所示。
如果在电池电源上运行，性能不会受到限制，因为Fire Strike ，主电源和电池上的得分非常相似。

能源管理
消耗功率
该系统非常省电，在桌面上闲置时仅消耗2瓦至7瓦，这取决于电源配置文件和亮度设置。运行游戏级负载将需要大约45瓦，或比LG Gram 14T90N多出大约36%的功率。然而，GPU的性能至少快了2到3倍，因此，较高的功耗是非常值得的图形收益。
当CPU处于100%的利用率时，我们能够从小型（约9.8 x 6 x 2.7厘米）65瓦的USB-C交流适配器上记录到66瓦的最大临时功耗。

电池寿命 - 全天的浏览量
电池容量与老款Gram 14T90N相同，都是72Wh。也许不是巧合，他们的WLAN运行时间也几乎相同，实际浏览时间刚刚超过12小时。很高兴看到电池寿命没有受到影响，即使与第十代Comet Lake-U相比，处理器的性能已经显著提高。
从空电到满电的充电时间非常慢，为2.5小时，而其他大多数超极本的充电时间为1.5小时或更快。

Verdict — The Gram To Get
比平均水平更轻的重量、清晰的16:10 DCI-P3触摸屏和出色的电池寿命都是Gram 14T90P的亮点。它的新设计在不增加任何重量的情况下更加强大，以保持14英寸Gram系列相对于竞争对手的最大优势之一，如更重的联想Yoga 9 14 ，惠普Spectre x360 14 ，或戴尔XPS 13二合一 。机箱的刚性可能稍差，但对于旅行者或学生来说，节省的重量可能值得一试。
格兰14T90P是14英寸格兰系列需要的全面更新。
不幸的是，有一个体面的清单，我们希望看到改进的隐患。充电速度慢，游戏时帧率不稳定，点击板海绵状，显示屏亮度一般，缺乏对Windows Hello的支持，维修困难，铰链硬度一般，所有这些都使一台本来很好的14英寸可折叠机降级。如果LG能在保持低重量的同时解决这些主要缺点，那么Gram 14将很容易与戴尔、联想或惠普的更受欢迎的替代品相提并论。
