结论 - 相对较小的更新
戴尔 14 Premium 是对去年的 XPS 14.除了将 Core Ultra 7 155H 替换为 Core Ultra 7 255H，用户体验基本保持不变，因为两款机型之间没有任何外部差异，甚至包括它们的三星 OLED 触摸屏。备受争议的键盘依然存在，可选的GeForce RTX 4050 显卡也是如此。
值得注意的是，与 XPS 14 中的 Meteor Lake-H CPU 相比，Core Ultra 7 255H 能够在更长时间内保持更快的 Turbo Boost 时钟速率。使用 Arc 140T 的图形性能仅比 Arc 8 略快，因此强力用户可能还是要考虑 RTX 4050 配置。除此之外，去年的 XPS 14 在基本多媒体和多任务处理场景下的性能基本相同，而价格却更低。
我们的测试配置要价 2000 美元，值得仔细研究，因为替代品如 华硕 Zephyrus G14或 雷蛇刀锋 14价格完全相同或更低，但图形处理性能更快，外形尺寸也类似于 14 英寸。在这方面，休闲游戏玩家或性能猎手可能会从某些替代产品中发现更多价值。
Pros
+ 14 英寸外形尺寸的 Core Ultra H
+ 所有 SKU 均标配 120 Hz
+ 3 个雷电 4 端口
+ 电池寿命长
Cons
- CPU 在长期压力下可能会节流
- 没有GeForce RTX 5050 选项
- 在长时间压力下声音较大
- 无摄像头隐私快门

2025 Dell XPS 14 9440 Laptop (14.5" FHD+, Intel 16-Core Ultra 7 155H (> i9-10885H), 16GB RAM, 1TB SSD) AI PC for Creator, Business, Engineers, Backlit KB, Fingerprint, RGB IR Webcam, Win 11 Pro
戴尔 14 Premium 直接接替了去年的 XPS 14。此次更名是戴尔更大计划的一部分，即逐步淘汰产品系列中的 "XPS"、"Latitude"和 "Precision"等专有名词，转而使用 "Premium"、"Plus "或 "Pro "等更直观的词语。除此之外，机身并无其他重大变化，因此我们建议您查看我们的 XPS 14 的评测了解戴尔 14 Premium 的更多物理特性。
我们的测试机属于中等配置，配备 32 GB 内存和 3.2K 120 Hz OLED 触摸屏，售价略低于 2000 美元。低端型号的内存和存储空间只有一半，配备 2K IPS 显示屏，而高端型号则配备 30 W 独立GeForce RTX 4050 GPU。酷睿至尊 7 255H 处理器保持不变。

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 | ||
|---|---|---|
| 0.96 ms ... rise ↗ and fall ↘ combined | ↗ 0.45 ms rise |  |
| ↘ 0.51 ms fall | ||
| The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 2 % of all devices are better. This means that the measured response time is better than the average of all tested devices (20.4 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 0.72 ms ... rise ↗ and fall ↘ combined | ↗ 0.37 ms rise |  |

| The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 2 % of all devices are better. This means that the measured response time is better than the average of all tested devices (31.9 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 detected | 475 Hz Amplitude: 23 % |  | |
The display backlight flickers at 475 Hz (worst case, e.g., utilizing PWM) . The frequency of 475 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8276 (minimum: 5 - maximum: 343500) Hz was measured. | |||

处理器
酷睿至尊 7 255H 酷睿至尊 7 255H在戴尔 14 Premium 上表现出色，至少对于 14 英寸的小型超极本而言是如此。大多数采用相同 CPU 的笔记本电脑往往比我们的戴尔 14 Premium 更大和/或更厚，因此戴尔 14 Premium 的尺寸更小，自然导致温度控制更严格，Turbo Boost 的优势也更有限。下面的 CineBench R15 xT 循环图显示，前几个循环的性能比较稳定，之后性能下降了 35%。好的一面是，性能的持续性至少比 XPS 14 好。

系统噪音
双风扇几乎始终处于活动状态，尽管转速很低，以至于在浏览网页或视频流时不易察觉。不过，当负载较高时，由于 H 系列 CPU 的 TDP 要求较高，双风扇的转速会比其他 U 系列或 V 系列 14 英寸超极本更快。当系统运行压力较大时，整体风扇噪音会明显变大。

压力测试
在运行 Prime95 对 CPU 施加压力时，平均时钟频率会在 60 瓦和 104 摄氏度的条件下升至 3 GHz。当然，这样的温度长时间持续会让人不舒服，因此在测试开始一分钟左右后，处理器就会迅速降至 2.5 GHz、42 瓦和 85 摄氏度。
如下表和截图所示，在运行《赛博朋克 2077》时也会出现类似的时钟频率节流现象。时钟频率的波动与 GPU 性能部分的帧速率低于预期的结果一致。
| CPU 平均时钟 (GHz) | GPU 时钟 (MHz) | CPU 平均温度 (°C) | |

耗电量
平均功耗高于大多数 14 英寸超极本，这主要归功于 H 系列 CPU。不过，当系统受到压力时，功耗会出现波动，这与上文提到的 Turbo Boost 时钟频率波动是一致的。
