外壳和功能 -Latitude ，带USB 3.2 Gen 2
不显眼的黑色塑料外壳以磨砂、粗糙的表面为主，可以防止指纹。外壳的窄边提供了一些变化。它们有光滑的、有光泽的表面。机箱没有显示出任何工艺上的缺陷。底座单元可以扭动得有点多--它缺乏硬度。电池（用螺丝固定，不是用胶水）和其他内部零件在拆下底座后可以接触到。
3520有三个USB-A端口（2个USB 3.2 Gen 1，1个USB 2.0）和一个USB-C端口（USB 3.2 Gen 2）。后者通过USB-C支持Power Delivery和Displayport。与HDMI端口一起，该笔记本有两个视频输出。SD存储卡读卡器（参考卡：AV Pro SD microSD 128 GB V60）是其中一个较慢的。积极的一面。网络摄像头（0.9MP）提供一个机械盖。
在最佳条件下确定的WLAN传输率（附近没有其他WLAN设备，笔记本和服务器PC之间的距离很小）非常好，与WiFi芯片（英特尔AX201；802.11 ax）的能力相符。戴尔有Latitude ，有集成LTE调制解调器的版本--本测试设备不是其中之一。改装是不可能的，因为插槽、天线和SIM卡座都不见了。

输入设备 - 3520配备了一个背光键盘
Chiclet键盘的光滑按键提供了一个短的行程和一个清晰的压力点。键的阻力还可以。键盘的轻微晃动并没有被证明是令人讨厌的。两段式的按键照明是通过一个功能键来调节的。总的来说，戴尔在这里提供了一个适合日常使用的键盘。
一个具有多点触摸功能的点击板（约11.5 x 8厘米/~4.5 x 3.2英寸）可作为鼠标的替代品。其光滑的表面使手指很容易滑行。触摸板对角落里的输入有反应，行程短，并提供一个清晰的压力点。
显示屏 - FHD面板，色彩空间覆盖率低
哑光的15.6英寸屏幕（1,920 x 1,080像素）在任何亮度设置下都没有显示出PWM闪烁。亮度和对比度没有达到各自的目标（分别为>300 cd/m²和1,000:1）--尽管有时只是勉强达到。一些竞争对手的屏幕有时会提供一个明显更好的对比度。

在交付状态下，屏幕显示的颜色相当好。然而，目标（DeltaE<3）没有达到，偏差约为4.5。校准只提供了微小的改进。
该显示器不能再现AdobeRGB（41%）、sRGB（60%）和DCI-P3（40%）色彩空间。因此，该面板不适合依赖色彩保真度的应用场景。竞争对手在这方面并没有更好的表现。

性能 - 戴尔依靠的是Tiger Lake
戴尔的Inspiron 15 3520是一款15.6英寸的办公笔记本，主要针对商务和私人用户。Tiger Lake 处理器（赛扬到酷睿i7）--英特尔的倒数第二代CPU，在该范围内使用。价格在500到900欧元之间（约合529美元到953美元）--取决于配置。
测试条件
戴尔电源管理器提供配置文件（见表）以影响笔记本的温度和功率发展。这些影响CPU的性能，GPU的性能不受影响。使用了 "超性能"（基准测试）和 "优化"（电池测试）配置文件。
| 超大功率 | 优化 | 冷却 | 静音 | |
|---|---|---|---|---|
| 功率限制1 | 30瓦 | 25瓦 | 14.75瓦 | 14.75瓦 |
| 功率限制2 | 51瓦 | 51瓦 | 51瓦 | 51瓦 |
处理器
芯片 酷睿i5-1135G7四核处理器（Tiger Lake ）的基本时钟为2.4 GHz。通过涡轮增压可以提高到3.8GHz（所有核心），最高4.2GHz（一个核心）。支持超线程。基准测试结果往往低于迄今为止测试的所有1135G7笔记本电脑的平均值。
Cinebench R15基准的多线程测试最初以3.3至3.5GHz处理，然后时钟降至3.1至3.2GHz。单线程测试以1.5至4.2GHz运行。在电池模式下，时钟速率较低。CB15循环测试证实了CPU Turbo在中等水平上的永久使用。

系统性能
运行流畅的系统可以处理办公和互联网应用以及适度的游戏。在单通道模式下运行的工作内存（8GB）妨碍了最大可能的计算能力的释放。安装第二个内存模块（=双通道模式激活）可以弥补这一缺陷，特别是对图形性能有积极影响。对于DDR4-3200内存来说，该内存的传输率处于正常水平。
单通道模式和（低于）平均水平的CPU性能的结合使3520在PCMark 10和Crossmark基准的比较领域中处于落后的位置。

DPC延迟
标准化的延迟监测测试（网上冲浪、4k视频播放、Prime95高负荷）发现了可能与网络适配器有关的异常情况。该系统似乎不适合实时视频和音频编辑。未来的软件更新可能会导致改进，甚至是退化。

大容量存储
戴尔为Latitude ，配备了来自Kioxia的PCI-4-SSD（M.2-2230；M.2-2280型号也适合），提供256GB的存储容量。传输速率很好，但它不是顶级SSD之一。笔记本没有空间容纳额外的存储介质。

图形卡
英特尔的iGPU可以在全功率（1300MHz）下永久工作--测试显示 Witcher 3测试显示了这一点。3520不是一款游戏笔记本。尽管如此，它可以在低设置下流畅地运行适度的游戏。低于平均水平的基准测试结果是由于工作内存在单通道模式下运行。通过安装第二个内存模块（=双通道模式激活），可以实现图形性能的提高。

噪声排放
在日常使用中（办公室、互联网）和空转时，风扇经常是静止的--安静的统治。在高负荷情况下，它的转速会升高。声压级可能达到近41.5 dB(A)。温度曲线 "静音 "通常会减少噪音的发展--以牺牲计算性能为代价。

温度
在日常使用中（办公室、互联网），机箱温度保持在绿色区域内。在负载（压力测试。 Witcher 3测试），笔记本平均仅有轻微发热，但在某些地方明显发热。在一个测量点，温度几乎达到50摄氏度（约122华氏度）。CPU的温度（约77摄氏度/~171华氏度）并没有引起关注。
压力测试（Prime95和FurMark连续运行）是测试全负荷下系统稳定性的一个极端情况。CPU（3.5 GHz）和GPU（1,200至1,300 MHz）以高时钟速率开始测试。虽然GPU的时钟在整个持续时间内基本保持不变，但CPU的时钟在几秒钟后就下降了。
(+) The maximum temperature on the upper side is 37.5 °C / 100 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(-) The bottom heats up to a maximum of 49.7 °C / 121 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25 °C / 77 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 24.8 °C / 76.6 F and are therefore cool to the touch.
(+) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (+2.9 °C / 5.3 F).

能源消耗
对于这里安装的硬件来说，耗电量处于正常水平。在压力测试期间，由于CPU时钟被降低，所以功耗下降了。电源（65瓦）的大小足够了。

电池寿命
Latitude 在实际的WLAN测试中实现了9:07小时的运行时间（通过脚本调用网站时的负载映射）--这是一个不错的速度。它将大多数竞争对手甩在后面，只有 ProBook有更大的耐力。
Pros
Cons
结论 - 一个坚实的，但（太）昂贵的办公笔记本
戴尔的工作笔记本是一个真正的赢家，这得益于 酷睿i5-1135G7CPU、8GB内存（单通道模式）和PCIe-4-SSD（256GB）。不再是全新的Tiger-Lake处理器提供的性能率仅低于迄今为止测试的所有1135G7笔记本的平均水平。
一个电池的电量足以让WLAN运行约9小时--这是一个很好的速率。电源是通过USB-C电源适配器补充的。另外，也可以使用戴尔专有的电源适配器；有一个合适的插槽。然后USB-C端口（USB 3.2 Gen 2）将可用于其他任务。
屏幕变成了Latitude 3520的最大弱点。
哑光FHD屏幕（15.6英寸，IPS）的亮度、对比度和色彩空间覆盖率原来太低--目前价格水平的笔记本电脑必须提供更多。这在其他方面也是如此。一年的保修期和在单通道模式下运行的工作内存都太少了。至少这款笔记本电脑有一个背光键盘。
另一个选择是 联想ThinkBook 15 G4.它的电池运行时间略短，但计算能力有明显提高。装备了1135G7的 Acer Extensa 15 EX215-54这将是一个需要妥协的预算选择：约500欧元（约529美元）的价格将与较短的电池运行时间和视角不稳定的TN屏幕相对立。此外，没有Windows操作系统。
价格和可用性
戴尔Latitude 15 3520在测试配置中的价格为774欧元（约合819美元），在Cyberport.de上有售。.
