戴尔Latitude 7340 笔记本电脑评测： 0.减轻 22 磅，对性能的影响微乎其微
查看 14 英寸紧凑型 戴尔Latitude 7440几周前，我们曾评测过 14 英寸的小巧型戴尔 7440。戴尔Latitude 7340 的尺寸为 13.3 英寸，比它小了不到一英寸。尽管尺寸较小，但它拥有基本相同的规格，采用了 英特尔酷睿 i5-1345U
关键的问题是：外形尺寸的缩小是否会影响性能？考虑到散热、电池和其他组件的空间有限，更小的机箱能否保持相同的性能水平？这是我们对戴尔Latitude 7340 进行评测的主要重点。此外，测试对象还与其他小型笔记本电脑竞争，包括价格较低的 戴尔Latitude 3440以及功能更强大但价格更昂贵的 惠普蜻蜓 G4.

外壳和连接性 - 超轻、紧凑的镁合金外壳
戴尔Latitude 7340 采用光滑、优质的镁合金边框，质感舒适，颜色为深灰色。超轻版的重量约为 2.4 磅，与其他 13.3 英寸笔记本电脑的重量相当。有趣的是，尽管显示屏尺寸较小，但与Latitude 7440 相比仅减轻了约 0.22 磅。因此，两者之间的差异并不明显。
Latitude 7340 的左侧有两个 Thunderbolt 4 端口，每个端口都具有 DisplayPort 和 Power Delivery 功能。此外，还有一个 HDMI 端口和一个 USB 3.2 Type-A 端口。该设备提供可选的 LTE 移动连接（WWAN），并支持 Wi-Fi 6E 和蓝牙。 值得注意的是，WLAN 速度在 6 GHz 时表现出色，但与竞争对手相比，在这方面还存在不足。
该笔记本内置 1080p 网络摄像头，可使用滑块手动遮盖。不过，值得注意的是，该摄像头不能准确捕捉色彩（11.8 ∆E），性能明显不如上一代产品 Latitude 7330.
在环保方面，戴尔选择取消塑料包装，体现了对可持续发展的承诺。
输入设备 - 小空间几乎得到最佳利用
由于体积小巧，Latitude 7340 为键盘提供的空间有限。戴尔几乎利用了整个设备的宽度，只在左右两侧留出了 0.79 英寸的空间。除数字键盘外，这样的布局可容纳约 0.63 x 0.63 英寸的按键。
戴尔巧妙地将指纹传感器集成到了电源键的右上角。F1 至 F12 键保留了音量和亮度控制等传统功能。此外，用户还可以通过这些按键调节键盘的三档照明（关闭、昏暗、明亮）。
在下部区域，戴尔放置了一块 4.93 x 2.67 英寸的触摸板，触感舒适，点击声音小。总的来说，触摸板几乎没有什么可挑剔的地方，有助于实现完美的用户体验。
显示屏 - 哑光且足够明亮的 FHD+ 屏幕
IPS 面板的宽高比为 16:10，分辨率为 1,920 x 1,200 像素（FHD+）。这种配置提供了一个略高的屏幕，这对紧凑型 13.3 英寸显示屏的观看体验产生了积极影响。
图像亮度值得称赞，平均超过 400 cd/m²，但略低于Latitude 7440的 1600p 面板值略低。这一特性与哑光显示屏相结合，使该设备能在户外有效使用。对于一款专为移动而设计的笔记本电脑来说，这一功能至关重要，尽管它并不总是有保证。
戴尔Latitude 7340 在测试的所有测量项目中都表现出色，没有出现任何明显的问题。虽然它的色彩空间覆盖率很高，但对于专业图形编辑来说可能还不够。不过，通过适当的校准，色彩还原能力可以得到显著提高。

性能 - Raptor Lake-U 配备 vPro，性能牺牲较小
戴尔Latitude 7340 采用第 13 代英特尔处理器，支持 vPro。具体来说，它采用了英特尔英特尔酷睿 i5-1345U处理器，搭配英特尔 Iris Xe 图形处理器 (80 EUs)、16 GB LPDDR5 内存和 512 GB M.2 PCIe NVMe 固态硬盘。
此外，戴尔还提供其他几种配置，用户可以选择英特尔 酷睿 i5-1335U和 英特尔酷睿 i7-1365U处理器。
测试条件
在性能测试中，我们主要使用了戴尔优化大师（Dell Optimizer）中的 "超性能 "模式，这是戴尔自己的软件。如果需要，该模式可将温度管理设置与 Windows 能源性能首选项同步。用户可以选择 "优化"、"冷却 "和 "安静 "等模式，根据自己的具体使用情况和偏好调整参数。
处理器
集成 英特尔酷睿 i5-1345U属于 Raptor Lake U 系列，共有十个内核（两个性能内核和八个效率内核），主频高达 4.7 GHz。它还支持 vPro 企业管理功能。
这款处理器也用于较大的 Latitude 7440中使用，其性能更佳。在我们的性能测试中，Latitude 7340 一直明显落后于稍大一些的同类产品。看来，更紧凑的尺寸及其相关限制对其整体性能产生了影响。
Latitude 7340 的性能与 13.3 英寸的Latitude 3440 相当，后者使用相同的 CPU，但级别较低。总的来说，这款评测机并没有充分发挥处理器的潜力，因此低于 CPU 的平均水平。

图形卡
戴尔决定不在Latitude 7340 中采用专用图形解决方案，这一决定符合轻型子笔记本电脑的概念。取而代之的是英特尔 Iris Xe 图形处理器（80 EUs），该处理器在 Latitude 7440对比机型中也有配备。
显然，这一设计因素并没有对图形性能产生重大影响。常见的 3DMark 基准测试通常显示，较小的机型仅略微落后于其 14 英寸的表兄弟，有时甚至领先。这些差异微不足道。
在测量游戏帧率方面，差异略微明显。Latitude 7340 每秒输出的帧数通常要少几帧，但这并不会真正影响游戏的可玩性。大多数游戏在最低设置下都能正常运行，这对于该级别的设备来说通常是可以接受的。
在 3DMarkTime Spy 压力测试中，96% 的成绩凸显了该机长期以来相对稳定的性能。基准测试显示，即使在电池模式下，大约 90% 的性能仍然可用。

评语 - 紧凑型笔记本电脑中的佼佼者，在测试中几乎没有弱点
如果将 13.3 英寸的戴尔Latitude 7340 与稍大一些的 14 英寸 Latitude 7440如果我们将 13.3 英寸的戴尔 7340 与稍大一些的 14 英寸 7440 进行比较，这里测试的这款超小型笔记本重量稍轻，体积更小巧，但由于硬件几乎完全相同，因此在许多方面都能跟上其较大系列的兄弟。虽然性能普遍略低，但差距是可控的。
由于采用了相同的电池，但功耗有所降低，因此延长了电池寿命。
最后，戴尔Latitude 7340 在我们的测试中被证明是一个小伙伴，它能够处理典型的办公任务，并凭借足够明亮的哑光显示屏适合户外使用。
如果你觉得 13.3 英寸的产品太小，那么 14 英寸的产品屏幕尺寸稍大，性能也更强一些。另一方面，如果内置处理器的性能无法满足你的需求，你可能会考虑选择同样小巧的 惠普蜻蜓 G4.
价格和供应情况
戴尔提供多种配置的Latitude 7340，起价约为 1589 美元。此次评测的 Ultralight 版本配备了英特尔酷睿 i5-1345U 处理器、16 GB DDR5 内存和 512 GB 固态硬盘，售价约为 1600 美元，可直接从戴尔公司购买，也可在Best Buy 等零售商处找到各种配置的产品。.
