Gigabyte U4 UD 笔记本电脑评测。轻量级,有很大的潜力,但有时会被浪费掉
通过U4 UD,技嘉推出了一款有趣的次笔记本,配备14英寸全高清显示屏和Windows 11,价格低于1,000欧元(约1,120美元)。它的独特品质之一是仍然比较新的 英特尔酷睿i7-1195G7,到目前为止,我们只在一个评测样本中看到过它。没有专门的图形解决方案,而板载的Intel Iris Xe Graphics G7 96EUsGPU被用来代替。此外,制造商还为该设备配备了16GB的DDR4内存和大量的端口选择。
我们将技嘉U4 UD与稍微昂贵的微星 Prestige 14 Evo A11MO-026US有相同的CPU/GPU组合。此外,HP Envy 13-ba1475ng搭配稍弱的i7-1165G7和专用的GeForce MX450显卡,以及戴尔 Inspiron 13 5301-0D0XN配有更弱的i5-1135G7/Iris Xe G7 80EUs组合,这两款产品属于同一价格区间,也被加入到组合中。在电池寿命方面,LG Gram 14Z90P-G.AA79G拥有i7-1165G7和Iris Xe G7 96EUs的耐力神童是最艰难的竞争对手。

非常轻的副笔记本,装在一个简洁而坚固的铝制外壳中
技嘉U4 UD被安置在一个设计适中的铝制外壳中,给人留下了可敬和高质量的印象。该设备提供了足够的抗扭能力,即使只从一个角落抱着它,也可以随身携带。它还符合MIL-STD 810G军事标准,这意味着该设备可以防止振动、极端温度和湿度。
铰链非常坚硬,打开后的显示屏几乎没有任何晃动或摇摆的感觉。然而,该设备只能用一只手用很多技巧打开,这也是由于重量低。
在不到一公斤的时候,技嘉U4 UD是这个比较领域中最轻的笔记本电脑,仅次于LG Gram 14Z90P。这是相当了不起的,因为也有一些13.3英寸的型号。这款14英寸的设备在宽度上是最大的,只有几毫米,但在深度和厚度方面,它可以很好地跟上其他副笔记本。总的来说,它是一个相当紧凑的,最重要的是,它是一个特别轻的旅行伴侣。
连接性。Thunderbolt 4和高数据速率
毫无疑问,技嘉U4 UD首先是一个紧凑的办公和多媒体笔记本电脑,除了在旅行时,在桌子或沙发上也很好看。分布在设备左右两边的端口配置也与此相符。
外部显示器可以使用Thunderbolt 4或HDMI 2.0端口连接。每侧都有一个USB-A端口(一个USB 3.2 Gen 1端口和一个Gen 2端口),但不幸的是,左侧只有一个USB-C端口。此外,这些端口的位置相对较近,因此,在左侧连接的稍厚的USB Type-A棒很可能挡住Thunderbolt/USB-C端口。
SD卡阅读器
这款读卡器,不幸的是只支持microSD而不支持SD卡,在我们对技嘉U4 UD的测试中表现得很好。当用128GB AV PRO microSD V60测试卡复制JPG格式的照片时,它显示了最好的性能。在使用1GB文件的阅读测试中,该读卡器的速度仍足以排在第二位,仅次于LG Gram,但也高于副笔记本的平均水平。

沟通
该设备在我们的Wi-Fi测试中也有类似的表现。在发送数据时,它取得了明显的领先优势。然而,在接收数据时,它只能排在第三位,但数据速率仍然高于AX201 Wi-Fi模块的平均水平。

网络摄像头
相比之下,高清摄像头,不幸的是不能用机械快门挡住,只显示出平庸的结果。平均DeltaE为20,几乎是惠普Envy 13的两倍,这意味着网络摄像头在捕捉色彩时并不十分准确。图像总体上比较暗淡,但对于视频通话等普通任务来说已经足够--就像双阵列麦克风一样。
安全问题
除了Kensington锁端口,技嘉U4 UD还具有基于固件的TPM,并支持英特尔平台信任技术(Intel PTT)。遗憾的是,没有指纹传感器。
辅料
Gigabyte只包括一个65瓦的电源适配器,重量为200克,与笔记本电脑一起。U4没有包括其他特殊的配件--也没有任何可选配件。
维护
12颗小螺丝挡住了进入内部的道路。一旦这些螺丝被卸下,16GB的DDR4-3200内存中的8个可以被替换,但不能扩展。其他8GB的RAM是焊接的。此外,还有两个M.2 SSD插槽(1个PCIe 4.0,1个PCIe 3.0),因此可以安装另一个M.2 SSD。
担保
Gigabyte本身对电池提供12个月的保修。所有其他情况都由零售商提供保修,在德国是24个月。
输入设备。键盘在 "F1 "和 "F12 "之间提供了许多附加功能
键盘
由于左右两边的边框只有大约2厘米薄,尽管U4的机箱很紧凑,但技嘉还是设法把一个尺寸坚实的键盘装进了U4。单个按键约为1.5 x 1.5厘米,可以用一般大小的男性手轻松地打字。
因此,很快就能建立起熟悉而迅速的打字速度,并伴有令人愉悦的安静背景噪音。只有空格键(和许多其他笔记本电脑一样)在噪音方面比较突出,特别是在快速打字时。
由于背光灯可以在控制中心调节到5个级别,各个按键在黑暗中也很容易看到。亮度也可以用 "F4 "键作为选项来调节。许多其他功能,如管理外部显示器设置、打开或关闭显示器和网络摄像头等,都可以通过使用 "F1 "至 "F12 "键方便地控制。
触摸板
10.5 x 6.5厘米的触摸板位于键盘下方的中央。它有一种舒适、平滑的感觉,底部边界有两个常见的点击区域。在触觉方面,这两个区域并没有分开,使用时也不是特别安静。然而,鼠标光标绝对可以顺利地在屏幕上导航,没有问题。
在我们的笔记本电脑评测中,明亮的显示屏是一个令人愉快的方面。
技嘉公司在U4中安装了奇美公司的14英寸雾面IPS显示屏。它的分辨率为全高清,相当于1920x1080像素。刷新率为非游戏设备的通常做法,即60赫兹。
该显示器在许多测量中都取得了很好的成绩。在其他因素中,它提供了最明亮的图像,平均为426cd/m²。然而,根据测量结果,亮度分布可以更均匀一些。
当涉及到黑色水平时,技嘉U4显示出弱点,而且对比度也略微落后于竞争对手。作为回报,该面板提供了最低的平均响应时间。

该显示器几乎100%覆盖了sRGB色彩空间,但只覆盖了约67%的AdobeRGB和65%的P3色彩空间。这使得该设备不太适合用于专业图形编辑。然而,这通常不属于像这样的副笔记本的常见应用目的。
开箱后的平均色彩偏差很好,但通过校准可以大大减少(DeltaE值分别为2.68和0.81)。
哑光和非常明亮的显示屏,以及IPS技术的高视角稳定性,使技嘉U4 UD非常适合户外使用。即使在阳光明媚的日子里,屏幕的可读性也不会受到影响。

性能。技嘉U4并没有充分利用其强大的CPU
如前所述,我们的评测设备配备了 英特尔酷睿i7-1195G7其Intel Iris Xe Graphics G7 96EUs集成GPU,以及16GB的DDR4-3200双通道模式的内存。除了UD配置,技嘉目前没有提供U4的其他版本。
与其他一些测量不同,我们使用控制中心3.0软件中的性能模式进行了基准测试。如果在这里选择多媒体模式,该设备在许多性能测试中都会有明显的速度损失。
处理器
芯片 酷睿i7-1195G7是今年年中才推出的。尽管它仍然基于现已过时的Tiger Lake 架构,但这是一次刷新。由于采用了10纳米以上的制造工艺,它特别节俭,但在Boost模式下,它的单个内核仍能达到5GHz。
最大的基础时钟速度是3.9GHz(28瓦的TDP)。我们的长期测量显示,技嘉为CPU提供了大约13瓦(PL1)到46瓦(PL2)的功率。与微星为Prestige 14 Evo提供的36至64瓦相比,这要少得多。
这也反映在不同基准测试的性能率上。U4远不能跟上配备相同CPU的竞争对手的步伐。在一些测量中,它甚至没有达到功能较弱的 英特尔酷睿i7-1165G7中发现的HP Envy 13.不过,在大多数情况下,它至少可以在与采用较慢处理器的竞争对手的竞争中占据优势。在Cinebench R15多重耐力测试中,其性能保持不变,尽管不是很高。当电源适配器没有插上时,CPU的性能下降了大约15%到20%。

系统性能
根据CPU基准测试,在系统性能方面,该设备也没有能够完全发挥处理器的性能。然而,由于与副笔记本的平均水平和对比设备相比,CPU本身就很强大,因此,它仍然足以获得中场排名和流畅的系统性能,完全能够满足日常使用。

GPU性能
Gigabyte没有采用专用的图形解决方案,而是选择了英特尔的 Iris Xe Graphics G7.这里安装了最强大的集成图形版本,有96个EUs。它保证了400MHz的最低时钟频率,峰值可达1400MHz。
技嘉在这里也把GPU放在一个很短的时间内,导致平均图形性能低于该图形解决方案在各种基准测试中的平均性能。此外,U4被其他大多数对比型号打败了,其中一些型号只配备了英特尔Iris Xe Graphics G7的80EUs。尽管如此,性能仍然足以满足日常任务,如流式传输高分辨率视频。电池供电时,性能下降了约15%。

游戏性能
由于技嘉U4没有利用最大的GPU性能潜力,游戏性能也仍然低于可能的水平,即GPU的平均值。该设备在《Witcher 3
》中与戴尔Inspiron 13在帧率方面进行了最后的对决。不过,这听起来比实际情况要糟糕。几乎所有测试的游戏都至少在最低的图形水平上顺利运行,许多甚至在中等水平上。技嘉U4足以应付偶尔的游戏环节,这对一台次笔记本来说应该是足够了。然而,更好的性能是可能的。
在《Witcher 3》中,使用Ultra图形级别的帧率不仅低得令人难以玩味,而且波动很大。虽然在CPU和GPU方面与同样装备的微星Prestige 14 Evo的差距 "只有 "大约5帧,但这是一个相当大的增长,即50%。

排放。意外的风扇噪音,但令人愉悦的低温度
风扇噪音
技嘉U4 UD在空闲使用时实际上是无声的。然而,在负载情况下,它的声音比其他对比设备要大一些,因为它达到了45分贝。
在测试中,我们发现更重要的是,即使设备没有被实际使用,而只是闲置在桌子上,风扇也经常转起来。这有点让人讨厌。它可以通过在控制中心3.0中选择静音模式来减少,但这将导致性能损失。另一方面,我们没有遇到任何其他噪音,如线圈啸叫,这是一件好事。

温度
在闲置的情况下,设备的温度一直保持在30℃(约86°F)以下。手掌休息区的温度几乎不高于室温。在负载情况下,该值最多增加10°C,因此达到的峰值只有37°C(约98.6°F)。简而言之:技嘉U4 UD保持着令人愉快的凉爽。
压力测试
在我们的标准化压力测试中,U4表现出随时间推移而节流的现象。在一个短暂的峰值之后,特别是时钟速率下降到一个非常低的水平。从长远来看,CPU稳定在800MHz左右(低于基本的时钟速度),GPU稳定在450MHz(约为最低时钟速度)。然而,这仍然导致温度适中,约为55℃(约131°F)。这也解释了为什么该设备的外部温度很低。

电池寿命
由于上述的消耗和36.7瓦特的电池,这是我们比较领域中最小的电池,电池寿命不会让任何人震惊。该设备在负载情况下持续了不到2个小时,在降低亮度的情况下浏览时约为4:30小时,在一次充电后观看视频时约为5:30小时。这还不足以吓倒竞争对手,而且它也落后于副笔记本的平均水平。
用低重量作为借口在这种情况下并不适用。LG Gram的重量和它一样轻,但它的电池是它的两倍大,而且它能从电池中获得更多。也就是说,它的价格也高得多。

Pros
Cons
结论:技嘉U4 UD在测试中浪费了潜力
通过U4 UD,技嘉公司提供了一个紧凑的副笔记本,其不到1公斤的重量特别吸引人。它的做工质量很高,设计也很简洁。
内置的CPU保证了开箱即用的性能,但技嘉并没有完全利用它。因此,该设备通常可以在具有较慢CPU的对比型号中保持其地位,但它没有达到预期。
这也适用于GPU,因此也适用于游戏性能。尽管如此,在两个较低的图形水平下,它足以满足一轮游戏的需要--无论如何,你不能对大多数副笔记本抱有更多期望。
虽然端口配置还不错,但在其他重要方面,如电池寿命方面,技嘉U4 UD不得不忍受批评。一方面,这是由于相对较高的消耗率,另一方面,由于该设备拥有测试领域中最小的电池这一事实。
总的来说,技嘉U4 UD在我们的测试中提供了坚实的表现,但由于一些批评意见,它也错过了一个更好的评级和绝对的购买建议。因此,该设备主要适用于那些正在寻找价格低廉、特别轻巧的副笔记本,但在续航能力方面没有特别高期望的潜在买家。
如果平均约4小时的运行时间还不够,用户应该考虑LG Gram 14Z90P-G.AA79G而那些寻求更多性能的人将会满足于 MSI Prestige 14 Evo A11MO-026US它采用了相同的CPU/GPU组合。
