结论--更精简、更高效，并配备 OLED 显示屏
从其暗淡的哑光灰色外观上看不出什么端倪，但戴尔 Pro 14 Premium 隐藏着大量与去年的Latitude 7440 或Latitude 9440 系列相比的升级和变化。它最显著的特点可以说是全新的 OLED 触摸屏，它带来了以前老款Latitude 14 所没有的保真度。同时，Lunar Lake CPU 在图形处理性能和能效方面都有显著提升，尽管整体性能更快，对 OLED 面板的要求更高，但电池续航时间明显长于上一代产品。
虽然没有什么大问题，但有几个小问题值得一提。OLED 面板虽好，但其 60 Hz 的刷新率在 90 Hz 或更高的刷新率已成为普遍现象的今天却显得不合时宜。在存储方面，升级选项非常有限，尤其是摄影师或编辑可能会讨厌没有集成 SD 卡读卡器，无法更好地利用 OLED 色彩和更快的集成图形处理能力。打字体验比 HP EliteBook Ultra G 14 稍微浅一些，也更有弹性。 惠普EliteBook Ultra G1i 14惠普 EliteBook Ultra G1i 14 也比戴尔更薄、更轻（尽管可修复性较差），同时还配备了更快的 120 Hz OLED 选项。戴尔 Pro 14 Premium 仍是戴尔最适合企业使用的子笔记本之一，与Latitude 14 的前代产品相比也有所改进，但它还需要一些额外的动力来进一步超越竞争对手。

规格
案例
骨架主要是镁合金，具有出色的刚性和抗扭曲、抗凹陷能力。我们在Latitude 7440 上观察到的问题在戴尔 Pro 14 Premium 上并不存在，因此总体感觉与Latitude 9440 比较相似。
与惠普 EliteBook Ultra G1i 14 或联想 ThinkPad T14s Gen 6 等竞争机型相比，该系统并没有特别弱或特别强的感觉，但与惠普相比，我们确实更喜欢戴尔更坚硬的铰链。
尺寸和重量与Latitude 7440 几乎完全相同。如果要吹毛求疵的话，戴尔 Pro 14 Premium 的尺寸和重量可能会略微小一些，但在其他方面厚度是一样的。
连接性
与Latitude 7440 相比，少了一个 USB-A 端口。为了弥补这一不足，两个 USB-C 端口中的一个被移到了机身右侧边缘，以便更符合人体工程学原理地进行充电或对接。
交流
标配的英特尔 BE201 支持 Wi-Fi 7 和蓝牙 5.4 连接。广域网和 nanoSIM 插槽为可选配置。

维护
底部面板由七颗十字螺丝固定，便于维修。进入机箱后，只有电池和主 M.2 固态硬盘是可拆卸的，因为 WLAN 和内存模块是焊接的。请注意，双风扇比Latitude 9440 2 合 1 的风扇稍大。
可持续性
这是首批配备模块化 USB-C 端口的商用 PC 之一，其设计便于在需要时进行更换。相比之下，大多数其他笔记本电脑的 USB-C 端口都高度集成在主板上，一旦损坏，维修或更换会更加困难。
按重量计算，该机型本身由 90% 的可回收镁材料制成，而包装则由 100% 的可回收或再生材料制成。
配件和保修
零售包装盒中除了交流适配器和文件外，没有任何其他附件。标准保修期为 3 年，并提供下一个工作日的现场维修服务。
输入设备
键盘
这里的零格键盘与在 Latitude 9440 二合一 相同的键入体验。虽然键盘美观，但回车键的反馈力度可能会更大，键程也可能偏浅。
触摸板
点击板与Latitude 9440 二合一版相比有所改变，显得更加传统。因此，它的尺寸略小（12.5 x 7.5 厘米对 13.5 x 9 厘米），所以感觉比以前更拥挤了一些，但在其他方面的功能没有问题。在按压其表面时，"咔嗒咔嗒 "的声音非常小，可以说偏向于海绵质感。
显示屏 - 美观的 OLED 但只有 60 Hz
1800p OLED 触摸屏是该机型的一项独特功能，是上一代Latitude 14 机型所不具备的。与基本的 IPS 配置相比，它具有通常的优势，如更深的色彩、黑白对比度、HDR 支持、更高的分辨率和更快的黑白响应时间，从而带来更好的观看体验。
该显示屏的主要缺点是基本刷新率为 60 Hz，亮度对于 OLED 面板来说一般。相比之下，XPS 14 的 OLED 选项具有更流畅的 120 Hz 刷新率，而联想 ThinkPad T14s 或 MacBook Pro 14 等竞争机型的显示屏都更亮。根据我们的测量，SDR 模式下的最大亮度限制在 400 尼特，HDR 模式下的最大亮度限制在 512 尼特。

The display backlight flickers at 241.1 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 241.1 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8374 (minimum: 5 - maximum: 343500) Hz was measured. | |||
OLED 触摸屏虽然清晰明亮，但其亮度仍不足以让用户在户外舒适地观看。色彩变得暗淡，眩光也不可避免。
性能--效率就是游戏规则
测试条件
在运行下面的基准测试之前，我们将戴尔优化大师设置为性能模式。优化程序的电源配置文件可以自动与常规的 Windows 电源配置文件同步，而联想或惠普的笔记本电脑并非总是如此。
处理器
酷睿 Ultra 7 268V 酷睿至尊 7 268V仅比 Raptor Lake 酷睿 i5-1345U或 酷睿 i7-1355U在执行传统 CPU 任务时，仅比去年Latitude 14 系列上的 Raptor Lake Core i5-1345U 或 Core i7-1355U 略快。这在很大程度上是有意为之，因为 Lunar Lake-V 专注于 NPU、GPU、RAM 和整体效率的提升，而不是处理器的原始性能。尽管如此，正如下面的 CineBench R15 xT 循环测试结果所示，酷睿至尊 7 268V 在受压时的节流现象较少，因此随着时间的推移性能更加稳定。

系统性能
与去年的Latitude 7440 或 9440 2 合 1 相比，PCMark 结果在数字内容创建子测试中提升最大，这归功于 Lunar Lake 集成 GPU 的显著加速。除此之外，传统的办公任务在戴尔 Pro 14 Premium 上的速度并没有提高多少，上文提到的处理器原始性能的提升相对较小就是例证。
由于 Lunar Lake 采用了独特的片上内存解决方案，因此内存性能几乎是旧版 Raptor Lake 架构的两倍。

系统噪音
风扇噪音曲线和表现与我们在 Latitude 9440 二合一鉴于它们具有许多相似的物理特性，这也许并不奇怪。戴尔 Pro 14 Premium 在进行网页浏览或文字处理等日常办公负载时基本上是静音的，脉动极小。如果风扇提速，当不再需要额外的处理能力时，风扇也会相对较快地降下来。
风扇噪音上限为 44 dB(A)，与我们在Latitude 9440 2 合 1 上记录到的噪音接近，比许多其他商用子笔记本都要大。音调也比较尖锐，因此比我们希望的要明显。

温度
表面温度比我们在Latitude 9440 2 合 1 和Latitude 7440 上记录的温度低得多。键盘表面和底部面板的热点温度分别仅为 33 摄氏度和 28 摄氏度，而上述Latitude 机型则为 40 摄氏度。这些改进主要归功于更高效的 Lunar Lake CPU。
(+) The maximum temperature on the upper side is 33 °C / 91 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 28 °C / 82 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 26 °C / 79 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 25.4 °C / 77.7 F and are therefore cool to the touch.
(+) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (+2.2 °C / 4 F).

压力测试
在启动 Prime95 压力时，CPU 会提升至 3.3 GHz 和 38 W，直到约 40 秒后核心温度达到 96 C。此后，性能会略微下降到 3 GHz 和 31 W，以保持较低的温度，即 80 C。因此，ULV 笔记本电脑的最大 Turbo Boost 受到了限制。
游戏时的核心温度保持在略低于 60 C 的水平，而Latitude 9440 2 合 1 则超过 80 C。毋庸置疑，戴尔 Pro 14 Premium 在运行 GPU 高负载时效率明显更高。

耗电量
与Latitude 7440 相比，该系统在运行 CPU 高负载时的效率提高了约 15%，同时在此过程中性能提高了 15%，从而提高了每瓦性能。与 Raptor Lake 相比，Lunar Lake 在人工智能加速任务或 GPU 繁重工作负载方面的优势更为明显。
当 CPU 的利用率达到 100% 时，我们可以记录到 60 W USB-C AC 适配器（约 6.5 x 5.5 x 2.2 厘米）的最大功耗为 61 W。

电池寿命
尽管电池容量变化不大，但运行时间比上一代Latitude 14 系列有所改进。在自动关机前，我们能够记录下略高于 15 小时的 WLAN 实际浏览时间，比Latitude 7440 在类似条件下至少长两个小时。如果配置的是基本的 IPS 面板，而不是 OLED 面板，电池寿命预计会更长。
从空电到充满电仅需 90 多分钟。
