戴尔Latitude 14 5420评论。一台接近夺取商务冠的笔记本电脑

酷睿i5到最大。 我们正在测试戴尔的主流商务笔记本电脑。尽管这款14英寸的设备似乎包括了你所希望的一切，但点击板是巨大的降级。在这次审查中，我们将详细探讨许多方面，如令人印象深刻的处理器性能和不太令人印象深刻的iGPU性能。

Windows Ultrabook Tiger Lake Thunderbolt

近1000美元的入门级商务笔记本电脑。戴尔Latitude 5420，配备酷睿i5-1135G7（D2G5W）。

戴尔的Latitude ，作为一个整体稳固的全能办公设备出现。机箱既不薄也不轻，很可能也不会赢得任何设计奖项。一台灰色的、不显眼的、低调的14英寸笔记本电脑--重点显然是在内部。不幸的是，这里也有一些错误的做法，我们的审查将显示。

不要吸引任何注意力!这是笔记本电脑的一个愿望，如联想ThinkPad L14, 惠普ProBook 440 G8，以及华硕ExpertBook B1.

由于我们的Latitude 是这一类别中最昂贵的之一，这就引出了一个问题，即它为其高价标签提供了哪些优势。1000美元只有8GB的内存和256GB的固态硬盘不可能是它的全部。在这个价位上，连接性、性能、输入设备，当然还有运行时间，都必须要更好。Latitude 5420是否能胜任这项工作？

前身。

案例: 实体戴尔笔记本电脑

碳纤维和镁合金加固的底盘具有很强的抗扭曲性。从主观上讲，它给人的感觉是沉重而坚固。由于铰链很牢固，必须按住底座才能打开盖子。虽然点击板前面的凹陷可以用一个手指抬起盖子，但底座在短短几英寸后就必须被按住。

与2020年的Latitude 5410相比，机箱在视觉上保持一致：下拉式铰链，低调的银灰色外观和黑色键盘。最大的视觉变化与输入设备的改变有关，这反过来也带来了使用性的变化。我们将在输入设备部分更详细地探讨这个问题。

电源按钮被移到了键盘的角落，在那里它以一个黑色按钮的形式存在。它可以作为Windows Hello的指纹传感器。

戴尔Latitude 14 5420的厚实底座在压力下不会屈服，盖子也感觉很牢固。对盖子的背面施加压力不会在LCD上产生颜色失真。只有右侧的键盘区域略微弯曲。

Latitude 14 5420的重量为1.5公斤（约3.31磅），可以说是中等水平，而 ThinkPad L14 G2AMD或 Acer Enduro Urban N3则明显更重。然而，撇开这两个型号不谈，Latitude 是我们比较中最厚的笔记本电脑--20.9毫米（约0.82英寸），没有脚。华硕华硕ExpertBook B1, Dynabook Tecra A40，以及惠普ProBook 440 G8都更薄、更轻。

连接性。具有大量安全功能的笔记本

这就是Latitude ，它能够将自己与其他笔记本电脑区分开来。Thunderbolt 4、一个传统的以太网RJ-45端口、智能卡读卡器、NFC和一个用于在旅途中访问网络的SIM卡插槽，构成了一个非常引人注目的清单。

沟通

除了AX201 Wi-Fi适配器和RJ-45以太网端口外，戴尔笔记本电脑还在显示屏下方配备了一个SIM卡插槽，可以从设备的背面进入。因此，Latitude ，可以加装一个兼容的LTE模块。

英特尔AX201的传输速度不太符合我们的期望，即使考虑到峰值也是如此。相比之下，峰值接收速度几乎达到1700-Mbps大关。

网络摄像头

盖子上的720p摄像头几乎不值得一提。它捕捉到的照片被冲刷掉了，存在着明显的伪影。尽管这对于视频会议来说可能已经足够了，但即使在这种使用情况下，更高质量的解决方案也是可取的。特别是由于宽大的边框可以为一个更高级的相机提供足够的空间。这款相机并不完全面临激烈的竞争，它也提供了一个平庸的体验。色彩的准确性很差，我们的测试图显示了明显的图像噪音。

安全问题

戴尔从谨慎的角度出发，用戴尔安全端口、集成智能卡读卡器和网络摄像头快门补充了指纹传感器。快门的工作原理是机械地密封网络摄像头。在它旁边，有一个红外传感器（红外摄像头），可以通过Windows Hello进行面部识别。如今，TPM 2.0是标准配置，因为Widows 11需要它。

辅料

除了65瓦的交流适配器外，没有任何额外的东西。

维护

这再容易不过了。松开十字螺丝，用塑料铲子在铰链之间撬开，取出底板。方便的是，螺丝不能从底板上掉下来。

在它下面，有两个内存插槽，Wi-Fi模块，一个用于LTE调制解调器的空插槽，以及一个容纳SSD的M.2插槽。尽管它看起来像一个M.2插槽，但LTE模块插槽与M.2 SSD不兼容。

担保

戴尔提供标准的一年制造商保修，其他都是可选升级。第三方供应商提供标准的12个月保修期，并有可选的附加服务。

输入设备。戴尔与点击板的灾难

键盘按键的背光有两个亮度级别，可以照亮按键的图例。与前代产品相比，这些符号并不那么明显。不过，背光在一定程度上弥补了这一点。键盘宽度为15毫米（约0.59英寸），在尺寸和间距方面是平均水平。键盘可以实现快速、舒适的打字。

键盘

由于键盘区域的硬度不均匀，所以它在右侧略微有点屈服。键的反馈总体上是好的。按键的启动点很明显，行程适中，按起来有弹性。与其他型号不同的是，Latitude 的按键上涂有一层橡胶材料。这可以防止手指从按键上滑落，从而获得更可控的打字体验。很难说涂层是否会随着时间的推移而脱落，从而使按键变得斑驳。

触摸板

遗漏Trackpoint和专用的鼠标按钮使5420被阉割到在输入设备方面几乎无法与普通消费类笔记本电脑区分开来。虽然削减Trackpoint可能仍然可以接受，但许多Latitude 的粉丝会非常想念四个鼠标按钮。

许多用户已经习惯并喜欢的触觉反馈，在这里没有了。触摸板是一种完全不同的野兽，处理方式也不同，这总是需要一些时间来适应。我们怀疑许多买家会被戴尔的决定吓跑，转而投向联想。虽然 ThinkPad L14 G2也配备了点击板，但它还包括上面的三个专用鼠标按钮和一个Trackpoint。

点击板也不完全是顶级的，至少如果你期望有触觉反馈的话。它的行程很浅，启动点很短，而且几乎没有任何声音反馈。对于那些试图安静工作的人来说，所有这些都是理想的--包括安静的按键。然而，如果你习惯于触觉反馈，这个触摸板将是一个巨大的失望。

触摸板有11.5厘米（约4.53英寸），对于一个14英寸的设备来说是相当大的，而与我们测试过的许多其他设备相比，其表面明显更钝。在表面上滑行时，有一些可以听到的阻力。由于缺乏行程，即使在触摸板的最底部，按钮也提供了非常不令人满意的点击。

显示。哑光14-Zoll面板，颜色不多

戴尔依靠的是传统的16:9-IPS 14英寸显示屏，1920 x 1080像素。157PPI的像素密度和60Hz的刷新率都不是特别令人印象深刻。亮度也是如此，最佳亮度为311尼特，平均为281尼特。值得庆幸的是，在电池模式下，亮度不会降低，这在一定程度上有助于磨砂面板的户外功能。我们没有检测到PWM。在1115:1的情况下，对比度是比较好的。IPS面板是这次迭代的标准配置，而具有较低分辨率的低成本TN变体已经被削减。

* ... smaller is better

14英寸机型似乎并不关注色彩空间。在最好的情况下，戴尔涵盖了54%的sRGB色彩空间。由于印前需要接近100%的数值，竞争对手往往不会在这个类别中明显领先，即使华硕ExperBook的64%在名义上更接近。竞争对手 Acer Enduro Urban N3是一个例外，它不仅拥有一个更明亮的显示屏，而且还拥有一个更好的显示屏，覆盖了92%的sRGB。

ColorChecker显示DeltaE为4.65，这个值很差，颜色偏差很大，肉眼就能看出来。不幸的是，我们的校准尝试的成功是有限的，对DeltaE 4的改善也是最小的。相比之下，经过我们的校准，灰度有很大的改善。从3.2到0.66的改善使我们分光光度计的使用几乎是值得的。我们的颜色配置文件可以从上面的方框中下载。

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
26 ms ... rise ↗ and fall ↘ combined	↗ 13 ms rise
26 ms ... rise ↗ and fall ↘ combined	↘ 13 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 51 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (23.3 ms).

The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.692 (minimum) to 636 (maximum) ms. » 54 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (36.8 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 21792 (minimum: 5 - maximum: 3846000) Hz was measured.

在户外使用时，Latitude 5420得益于其哑光面板。不幸的是，最大亮度对于非常明亮的环境来说是不够的。

优秀的可视角度是IPS显示屏的最大优势之一。

性能。带2分钟酷睿i5加速的笔记本电脑

我们的变体戴尔Latitude 5420，配有酷睿i5-1135G7，8GB内存和256GB固态硬盘（D2G5W）是该机型的基本配置，其售价略低于1000美元。有各种升级选项，价格在1400美元左右，包括i7-1185G7，16GB内存和512GB SSD。在我们的测试中，256GB的小型固态硬盘已经变成了一个特别的烦恼，因为在升级到Windows 11之后，只有105GB的存储空间可用--对于我们的游戏和应用基准来说远远不够。

测试条件

在测试之前，我们通过制造商的软件和Windows Update更新了所有驱动程序和BIOS。对于性能测试，我们启用了Windows性能模式以及戴尔的 "超性能 "电源配置文件。我们使用节能模式和 "优化"（戴尔温度）配置文件进行Wi-Fi和空闲运行时间测试。此外，我们启用了Windows 11电池保护模式。这项Windows功能限制了通知和后台活动，例如阻止OneDrive和电子邮件同步。

处理器

这款酷睿i5-1135G7是一个基于Tiger Lake 架构的多用途四核SoC，基本时钟为2.4GHz，加速时钟为4.2GHz，制造商可调整的TDP为12-28瓦，取决于可用的冷却能力。人们可能认为，厚实的机箱为良好的冷却解决方案提供了足够的空间，这反过来应该允许一个积极的TDP。然而，情况并非如此。尽管指定了57瓦的PL2（短期爆发），我们只看到了40瓦的PL1（长期）。40瓦将是一个相当保守的选择。

让我们来看看Cinebench R15的循环。前两个循环得益于40瓦的PL1，而系统总功率为50瓦。正如截图所示，短时爆发的57瓦的TDP从未实现。在第三个循环中，CPU处理其95℃（203°F）的SoC温度，通过将PL1降至35瓦和紧接着的31瓦。时钟频率也下降到3.5GHz（之前是3.8GHz；多核）。在这一点上，芯片温度已经下降到85℃（185°F）。由于这显然还是太高了，PL1被降低到23瓦，温度下降到72℃（161.6°F）。30秒后，SoC再次允许高达3.5 GHz的时钟速度，由于温度上升，2-3分钟后再次下降。

Dell Latitude 14 5420-D2G5W Intel Core i5-1135G7: Ø836 (755.62-919.65)

HP ProBook 440 G8-2W1G4EA Intel Core i7-1165G7: Ø670 (654.88-714.13)

Asus ExpertBook B1 B1400CEAE, i5-1135G7 Intel Core i5-1135G7: Ø734 (723.71-860.22)

Acer TravelMate P4 TMP414-51-59MR Intel Core i5-1135G7: Ø680 (614.84-797.19)

Acer Enduro Urban N3 EUN314 Intel Core i7-1165G7: Ø807 (480.95-841.33)

Dynabook Tecra A40-J-12E Intel Core i5-1135G7: Ø847 (840.09-894.41)

简而言之：所有迹象表明，一个精心设计的温度管理系统--尽管缺乏短时爆发--通过冷却关闭和提升阶段的交替，优化了长期峰值性能。

考虑到这一点，根据R15回路的连续性能是绰绰有余的，因为其他的 i5-1135G7其他i5-1135G7型号很难匹配或保持这一水平的性能。在连续压力下，Latitude 5420的性能只产生了9%的赤字。在前七个循环中，持续时间略长于两分钟，其持续的高性能令人印象深刻。看一眼CPU基准测试，就会发现这款Core i5的速度明显快于其同行的平均水平。事实上，它与记录分数只差几个百分点。该 Dynabook Tecra A40和华硕ExpertBook B1能够从SoC中挤出更多性能，很可能是通过使用PL2。

DPC延迟

至少在我们目前的驱动程序设置中（通过戴尔更新和Windows更新），Latitude 似乎是实时应用程序的次优选择。内核模式驱动程序产生了最显著的延迟，ACPI驱动程序是第二糟糕的罪犯。在我们的YouTube测试中，在播放1分钟的4K视频时，有11个帧丢失。

存储解决方案

西部数据的小型M.2-2230固态硬盘占据了一个长长的2280插座，它被一个框架固定在那里。它的速度很平庸，明显比次笔记本的平均速度慢。AS SSD的写入测试似乎特别慢。读取速度很快，尽管一段时间后速度下降，但它们稳定在一个中等水平上，仍然相当稳固。
