LG Ultra PC 14回顾。耐力与性能的结合
在回顾了16英寸Ultra PC之后,我们现在来看看它的小麻烦。14英寸的设备是一个克的替代品,它有很好的电池寿命,但并不是要尽可能的轻?我们现在已经可以告诉你,答案是肯定的。在启用Wi-Fi的情况下,Ultra PC 14可持续使用约17小时,在耐力方面超过了克14。
那么这就是关于该产品的全部内容了,对吗?当然不是。我们毕竟是在测试一个更昂贵的模型,它有一个 AMD Ryzen 7 5825U(25瓦)和16GB的内存。这款笔记本电脑不仅超过了英特尔的同类产品,而且在持续负载下与配备名义上更强大的最新一代45瓦处理器的设备处于同一水平。
根据规格的不同,Ultra PC的价格在800至1350欧元(870至1470美元)之间。在这个价格范围内,你会发现有一大堆采用AMD或英特尔处理器的轻薄便携式笔记本电脑。联想IdeaPad 5 Pro 14ITL6具有高清晰的显示屏,是一个高档的选择,你应该看一下。与Acer Swift 3 SF314和 惠普Pavilion Plus 14,提供更多性能(单核)的45瓦处理器已经进入14英寸笔记本电脑。

外壳和规格
克和超PC系列之间有什么区别吗?是的。例如,它们在重量(980克对1.29公斤,或2.16磅对2.84磅)和铰链设计方面有所不同(Ultra PC使用金属铰链,而gram上的铰链是隐藏的)。Ultra PC是由塑料而不是镁制成的,由于内部有强大的垂直和水平加固装置,它的底盘更硬。除材料外,Ultra PC有一个72Wh的电池,比LG gram中使用的特殊轻质电池更重。
底座部分和显示屏表现出一些适度的弯曲。与16英寸Ultra PC一样,轻轻扭转显示屏会立即导致TFT面板上出现明显的变色--这次不是在下边缘,而是在整个屏幕的上半部分。这种现象在某种程度上也出现在移动显示器时。也就是说,它不会对使用产生负面影响,而且当设备放在腿上或摇晃时也不明显。
说到端口,我们对Ultra PC 16的评价也适用于此:你可以使用USB-C充电器,而不是带桶形插头的65瓦适配器为设备供电(我们测试了45瓦和65瓦充电器)。
Ultra PC 14配备了一个英特尔Wi-Fi 6 AX200(带蓝牙5.1)。该模块的性能不如Ultra PC 16中的模块 ,在发射和接收率方面都不尽如人意。这两款Ultra PC上的读卡器提供了相同的速度。
14英寸的笔记本电脑与其16英寸的大哥共享相同的内部设计。唯一不同的是,这些部件被更紧密地排列在一起。看来这两款笔记本电脑使用了相同的主板;扬声器、电池和I/O板似乎也是相同的。有第二个SSD插槽可用于存储扩展,但内存是焊接的,无法升级。要打开这个设备,你只需要一把小的十字头螺丝刀。一旦螺丝被解开,底板实际上就会自己抬起来。
在德国,LG为LG Ultra PC 14提供两年的保修期,并可选择以50欧元(54美元)延长至三年。保修条款和条件可能因国家而异。例如,美国的标准保修期只有一年。

输入设备
Ultra PC 14的键盘没有背光,而且缺乏数字键盘。我们不能向那些经常打字的人全心全意地推荐这个键盘。尽管按键提供了很好的、清晰的阻力,但键盘在中间会弯曲。这使用户无法快速打字,并降低了笔记本电脑的质量感。触摸板的尺寸与16英寸超极本上的触摸板相同(13.2 x 8.2厘米,或5.2 x 3.2英寸)。它有一个明显的行程,一个明显的启动点和一个适度响亮的点击。
显示
不同于 Ultra PC 16采用的是LG面板,14英寸机型配备的是京东方的显示屏(NV140WUM-N44)。宽屏面板(1,920 x 1,200,16:10)同样存在黑屏的背光渗漏问题--这次主要是在下边缘。
Ultra PC的显示屏是哑光的,不反光,但LG gram笔记本电脑的屏幕分辨率更高(2,560 x 1,600)。我们的评测模型支持AMD Vari-Bright,它可以根据显示的内容来调整屏幕亮度。这个功能可以根据需要禁用。在331cd/m²,Ultra PC 14的峰值亮度高于Gram 14和Ultra PC 16。 Ultra PC 16.
我们测量了9和16毫秒的响应时间,这对于IPS面板来说是很好的、相当标准的数值。另一个积极的方面是,该显示器没有表现出任何PWM闪烁的现象。

在我们比较的设备中,Ultra PC 14的sRGB覆盖率最差。这可能与色彩准确性至关重要的应用有关。屏幕的1,600:1的对比度比竞争对手的能力要高一些,甚至超过了Gram 14。我们设法通过校准提高了色彩准确性,特别是灰度(Delta E从2.3降至0.7)。你可以在上面的方框中下载我们创建的颜色配置文件。

业绩
我们的评测设备配备了一个八核处理器-- AMD Ryzen 7 5825U(2.0 GHz,提升时钟可达4.5 GHz,L3缓存16 MB)。也有配备六核CPU(Ryzen 5625U)的低价型号。采用Ryzen 5或7的机型标配16GB内存(双通道)。
测试条件
LG智能助手现在可用于电源管理。在软件中,我们为基准测试将冷却模式设置为高,为电池寿命测试设置为低。我们将Radeon软件留在其默认设置中,这意味着省电的fps限制器被禁用。同样地,我们关闭了AMD Vari-Bright。在Windows中,所有省电模式被禁用,电源计划被设置为 "最佳性能"。对于电池寿命测试,我们允许Windows电池保护程序在平衡模式下运行。
处理器
凭借其8个内核和16个线程,... AMD Ryzen 7 5825U(TDP: 25 watts)将笔记本电脑变成了一个真正的工作机器。在我们的比较中,Ryzen CPU提供了出色的性能。它能够在持续负载下与英特尔酷睿i7-12500H(45瓦)保持同步,并且单核性能略高于酷睿i5-1135G7(28瓦)。但正如预期的那样,AMD Ryzen 7 5825U在多线程测试中表现更好,能够充分发挥其潜力。
当循环运行Cinebench R15 Multi时,Ryzen最初的得分是1800分,随后稳定在1600分的平均分。这款 酷睿i5-1240P在LG gram 14中的Core i5-1240P落后了相当多的分数,Ryzen的性能要好80-90%。

大容量存储
我们的Ultra PC在存储性能方面排在最后。三星PM991a硬盘在任何一项分项测试中都不是一个高分选手。考虑到这一点,这台笔记本电脑在PCMark 10中的分项得分高得令人吃惊。然而,CrossMark能够发现缓慢的固态硬盘,并且大多将评测单元置于最底层。正如你在DiskSpd图表中所看到的,固态硬盘在负载下的性能有适度的下降,但这并不奇怪。

图形卡
由于搭载了AMD Radeon RX Vega 8,Ultra PC提供了高于平均水平的图形性能,在我们的比较中超过了所有英特尔iGPU--至少在整体结果方面。Radeon iGPU在涉及子分数时处于中间位置,如Fire Strike 和Time Spy 。在任何情况下,LG gram 14(英特尔Xe Graphics G7 80EUs)在合成基准测试中大约慢15至20%。
在真正的游戏中,Vega 8对iGPU有相当好的表现,尽管其性能水平较低,在超便携产品中相当平均。这款笔记本电脑可以在最低或中等设置下流畅地运行旧游戏。在我们的测试中,Witcher 3 ,在设置为Ultra的情况下只运行了大约15帧,但至少帧率没有随着时间推移而下降。根据WiFiNFO的日志,CPU以恒定的3,900 MHz运行,而iGPU以2,000 MHz开始,在达到90°C(194°F)时节流到1,700 MHz。

从我们的测量结果来看,LG超便携笔记本电脑在办公室使用时(如基于浏览器的应用程序)是完全安静的,但在有活动时,风扇从未停止运行。在负载情况下,不管是运行压力测试还是游戏,单个风扇都会大幅旋转--我们从设备上测得的噪音约为45dB(A)。基于英特尔的LG gram 14在这方面明显更安静,但这是可以预期的,因为gram的性能更低。

温度
笔记本电脑在闲置时几乎不产生任何热量。我们测量时,其表面仅比室温高2-3℃(3.6-5℉)。在压力测试期间,机箱上的温度在某些位置上升到44-45℃(111-113℉)。这在大腿上是可以容忍的,因为较热的地方在设备的后面。
在压力测试期间,CPU和GPU的频率有大幅下降。在这种情况下,SoC的两个部分都在同时工作,同时不得不分享适度的TDP。CPU和iGPU开始时分别为30瓦和25瓦,然后随着测试的进行下降到20瓦和18瓦。在此期间,核心温度保持在大约90°C(194°F)。
(±) The maximum temperature on the upper side is 44.1 °C / 111 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(-) The bottom heats up to a maximum of 45.1 °C / 113 F, compared to the average of 39.4 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 24.5 °C / 76 F, compared to the device average of 30.7 °C / 87 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 33 °C / 91 F, compared to the device average of 30.7 °C / 87 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 30.7 °C / 87.3 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 28.3 °C / 82.9 F (-2.4 °C / -4.4 F).

这两个扬声器的声音相当体面,但缺乏低音。为了获得更好的听觉体验,我们建议使用一副耳机或外部扬声器。内置的双阵列麦克风最能产生无噪音的录音。

消耗功率
相对于其竞争对手,LG笔记本电脑的功耗相当不错。在我们的测试中,它在空闲状态下需要大约3.6到7.8瓦,在负载状态下平均需要46瓦,尽管它的用电量确实达到51瓦的峰值。这比我们比较中的基于英特尔的设备的功耗要高得多。紧凑的65瓦适配器能够轻松地处理这一水平的使用。

电池寿命
LG Ultra PC 14配备了72Wh的电池,是我们比较中最大的一个。在我们的Wi-Fi测试中,我们的评测设备在近17小时后才关闭。我们将屏幕亮度降低了四级,使其保持在150cd/m²的标准水平。在电池运行时,系统并没有节流,这导致了Battery Eater仅在令人失望的137分钟后就停止了。

Pros
Cons
结论--更有耐力
这是我们早在评测时的结论。 超强PC 16:对于预算紧张的人来说,Ultra PC系列不是LG gram的替代品。这是因为gram系列的主要亮点(即尽可能保持轻盈)并不适用于Ultra PC。14英寸的Ultra PC比其14英寸的gram对应产品重了高达360克(0.8磅)。不过除此之外,Ultra PC给人的感觉就像是克的复制品,电池寿命明显更长,设计也更简单。
以预算价格获得最大的电池寿命?如果你想要一台拥有明亮的亚光显示屏的笔记本电脑,而且一次可以使用17个小时,你应该看看LG Ultra PC 14。没有其他竞争对手甚至接近于提供这么多的外出耐力。
基于Ryzen 7的系统有很好的性能,即使在持续负荷下也能利用。然而,这也伴随着相当多的噪音。这款笔记本电脑的另一个优势是它的空M.2插槽,可以添加一个固态硬盘。太糟糕了,内存不能扩展(板载)。
在缺点方面,我们注意到显示屏在显示黑色图像时出现了变色和轻微的屏幕出血。底线是显示屏很亮,有很好的对比度,但你不应该期望它能再现宽广的色域。
在我们看来,这款笔记本电脑正在与联想IdeaPad 5 Pro 14ITL6等产品竞争。 惠普Pavilion Plus 14和 Acer Swift 3 SF314.这三款设备都有一个同样是亚光的高清晰显示屏,其中一些设备配备了强大的45瓦的SoC(惠普和宏碁的特点是i5-12500H)。但联想、惠普和宏基的笔记本电脑大约重100至200克(0.22至0.44磅)。
价格和可用性
目前在数码港已经没有评测模型,但你可以从LG德国直接获得它,1,350欧元(约1,465美元)。.另外,具有相同规格的16英寸版本可以以€1,099/1,299美元从LG的网上商店或Cyberport.
