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坚固的外观，扭曲时有轻微的嘎吱声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。

戴尔Latitude 5420

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。

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。

电源键中的指纹传感器辅料除了65瓦的交流适配器外，没有任何额外的东西。

65瓦的AC适配器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。

罕见：没有焊接，2个RAM插槽

简单。松开螺丝，打开盖子

值得称道。便于维护Latitude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。

有两个亮度级别的背光灯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。

清晰的启动点和坚定的反馈触摸板遗漏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，颜色不多子像素阵列AUO5491 / B140HAN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。

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。

Screen Flickering / PWM (Pulse-Width Modulation)ℹTo 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 detectedIn comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8265 (minimum: 5 - maximum: 343500) 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。

舒适地在外面工作，...

...并不总是可能的，因为最大的亮度充其量是平均水平。优秀的可视角度是IPS显示屏的最大优势之一。

IPS-面板AUO5491可视角度

IPS-面板AUO5491可视角度性能。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。

戴尔电源管理器 - 温度设置处理器这款酷睿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。

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。

存储解决方案用于SSD（256GB）的M.2 2280插槽西部数据的小型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。

游戏性能记录最终幻想X的CPU/GPU时钟和功耗游戏性能也遵循类似的趋势。 Iris Xe G7留下了40%到50%的潜力未被开发。这往往是可玩和不可玩之间的区别，如《Far Cry 5》在低速时分别为36和19 FPS。奇怪的旅》在低速时也有类似的情况：62对38FPS。

怎么会这样？ Iris Xe G7为什么戴尔笔记本电脑内的Iris Xe G7比预期的慢得多？时钟频率不可能是原因，因为它在FurMark中处于1200-1300MHz的理论最大值（约1240MHz），即使在65℃（149°F）的长时间压力下也是如此。对于我们用作基准的《最终幻想X》也是如此。iGPU为1200 MHz，CPU为1.6至3.8 GHz。由于GPU处于最大负荷状态，CPU以70%的功率运行，在我们22分钟的测试中，PL1在5分钟左右降至23瓦，在12分钟左右降至32瓦。游戏中的性能缺陷很可能是由于iGPU和CPU不得不分享TDP。具体发生了什么还不确定，但重复几次游戏测试并没有得到更好的结果。

排放。Latitude 可以非常安静系统噪音噪声特性

热管和一个单风扇Latitude 5420有两个方面。非常嘈杂和完全无声。后者的状态可以在空闲时观察到，风扇完全关闭。在浏览网页时，安静运行的机会很好，因为在低度到中度负载下，风扇大多会保持关闭状态。在最安静的状态下运行，在游戏或长时间压缩ZIP时，风扇产生36分贝（A）。虽然在这一点上已经明显可以听到，但由于其单调的性质，它仍然是可控的。在我们用Prime95和FurMark或R15循环和FurMark进行的压力测试中，风扇的音量大大增加。在这里，我们测量到了震耳欲聋的52 dB(A) - 这是游戏笔记本电脑的噪音水平。

竞争对手明显要安静得多，特别是联想ThinkPad L14 G2AMD。华硕ExpertBook B1，以及 Acer Enduro Urban N3.上述机型的平均噪音和最坏情况下的噪音都明显较小。似乎只知道最低的风扇设置，Dynabook Tecra A40也是如此。 Dynabook Tecra A40更加不显眼。幸运的是，我们的戴尔笔记本电脑包括一个风扇控制工具。

对于我们的测量和基准测试，我们默认为 "超性能 "模式。通过选择 "安静 "或 "平衡 "预设，噪音水平可以大大降低，即使在满负荷情况下，系统产生的噪音也不超过36分贝（A）。

温度温度适中，这证明了风扇处理热量排放的能力。排气口位于左侧边缘，而背部和风扇正下方的底板上的通风口则作为进气口发挥作用。在空闲时，顶部保持非常凉爽，热点在空闲风扇的情况下最差也只能达到30℃（86°F）。在负载情况下，温度会上升12度，达到42 °C (107.6 °F)。顶面的平均表面温度受影响较小，从28°C（82.4°F）上升到32°C（89.6°F）。我们测量了 "优化 "戴尔风扇控制模式下的空闲值和 "超性能 "模式下的负载值。

当使用 "安静 "模式时，温度可能会更高。

简而言之，没有什么可抱怨的。根据你的喜好，这款14英寸机型可以保持低温和安静，或者变得温暖，同时充分发挥其性能潜力。

压力测试在我们的压力测试中，我们观察SoC的温度和时钟速度。是否有明显的节流现象？风扇配置文件有多大的区别？在最初的十分钟里，"超性能 "配置文件是激活的，然后我们切换到 "平衡"。第一个模式允许PL1 40瓦的四分钟，然后下降并稳定在32瓦，直到10分钟后。

随后，我们切换配置文件，导致PL1立即下降到15瓦，偶尔在1分钟内提升到23瓦。这些峰值也显示在时钟速率和温度图中。我们的压力测试中最重要的结果。我们的Latitude ，能够无限期地保持2.0GHz。因此，它能够处理计算密集型任务。

为了证实我们的结果，我们专门运行了Prime95，同时记录了时钟速度和PL1值。在40瓦（3.3GHz）的情况下运行两分钟后，降至32瓦（3.0GHz）。

发言人发言人戴尔将两个立体声扬声器放在靠近底边的前角。虽然它们的最大音量还算可以，但声音不是很平衡。低音完全没有，高音也有些欠缺。虽然ThinkPad T14的扬声器更安静，但它们在整体上更加平衡。

麦克风录音没有任何缺陷，即使在0.5或2米远的地方说话也没有静电。

戴尔电源管理器 - 电池延长器。降低电池模式下的CPU性能

Dell Power Manager - Peak Shift。电池和交流电源调度器，例如，用于太阳能优化充电。戴尔在优化电力消耗方面做得很好。它在空闲时的功率很低（3-8瓦），而在负载时允许有高要求。我们测量的67瓦和35瓦的负载下代表了英特尔处理器的良好表现能力。具有相同SoC的竞争者，但负载下的功耗较低，如 ExpertBook B1和宏碁的TravelMate P4从芯片中获得的能量更少。下面的图表 "能源消耗外部监测 "也显示了这一点。在用Prime95进行CPU压力测试时，戴尔达到了迄今为止最高的功耗，甚至维持了整整两分钟。一旦iGPU开始工作，情况就不一样了，这也解释了游戏性能不理想的原因。

虽然67瓦的峰值功率对65瓦的交流适配器来说是个挑战，但我们在压力测试开始时只临时测量了67瓦。

戴尔的电源管理器允许与充电和电源管理有关的有趣选项。例如，太阳能电池阵的操作者可以选择只在白天给笔记本电脑充电，而在晚上严格依赖电池--即使是在连接交流适配器的时候。

电池寿命我们测量了实际的Wi-Fi运行时间，在显示亮度设置为150尼特和电池完全充电的情况下，几乎为13小时。Latitude ，只能用USB Type-C电源适配器充电，如附带的65瓦充电器。电池的容量为63瓦特/小时。我们没有测试电池扩展器（戴尔电源管理器），只依靠Windows 11的节能功能，该功能可禁用后台进程以及Windows电池保护模式。

令人难以置信的超长空闲运行时间（22小时）没有任何实际意义，而且是在显示屏设置为17坎德拉、禁用无线电模块的情况下测得的。

评语。点击率破坏了Latitude戴尔Latitude 5420（D2G5W），由数码港提供戴尔的Latitude 5420将自己表现为一台装备丰富的全能型商务笔记本电脑，在连接性和安全性方面没有任何不足。甚至可以加装一个LTE调制解调器。可升级性非常好，没有一个主要部件是焊接的。

我们很少看到如此善于在性能和低排放之间游刃有余的副笔记本。戴尔将缰绳交到用户手中，用户可以根据自己的愿望使用软件来调整参数。

当涉及到连续性能指标时，Latitude ，与大多数竞争对手相比，它的得分高于平均水平。虽然5420的PL2似乎没有到位，但它能够在两分钟内保持40瓦的高PL1。因此，尽管没有几秒钟的峰值提升性能（PL2），但它能够管理苛刻的日常工作负载。在这里，用户有一个选择。优化最高性能将诱发最高的噪音水平。或者，当设置为适当的配置文件时，笔记本电脑可以非常安静地运行，这将带来性能上的不足。

输入设备的变化并没有得到解决。Latitude ，而不是鼠标按键和Trackpoint，它提供了一个触觉效果很差的点击板，甚至连死忠的评论家都会求助于连接一个USB鼠标。

这是不幸的，因为Latitude 5420是一个伟大的通用型笔记本电脑，价格适中。潜在的买家可能想看一下联想的ThinkPad L142代，它的起价约为1000美元，提供了很好的升级选择，更快的处理器和更好的输入设备。然而，L14没有LTE天线和SIM卡插槽。对这一特殊功能感到兴奋的用户可能想亲自看看5420，自己判断一下点击板，因为这当然涉及到一定程度的个人偏好。

华硕华硕ExpertBook B1具有出色的显示屏和较少的升级选项，但明显缺乏LTE调制解调器。虽然也没有专用的鼠标按键，但点击板可以作为小键盘使用。

专门的鼠标按钮也没有出现在惠普ProBook 440 G8虽然维护和升级选项是相当的（除去LTE插槽）。由于它不仅缺乏Thunderbolt，而且还配备了更暗的显示屏，我们不推荐ProBook 440。

笔记本Acer Enduro Urban N3另一方面，它以非常明亮的显示屏、出色的性能、非常坚固的机箱以及最后但并非最不重要的可升级性而闪耀。甚至还有专用的鼠标按钮--不过，键盘只是消费者级别的。

总的来说，ExpertBook B1、ProBook 440和Enduro N3都是不太可能的选择，这就只剩下了 ThinkPad L14第二代。

价格和可用性类似配置的戴尔Latitude 5420目前可从亚马逊售价约为1000美元。
