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 | ||
|---|---|---|
| 40 ms ... rise ↗ and fall ↘ combined | ↗ 13 ms rise |  |
| ↘ 27 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 97 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 62 ms ... rise ↗ and fall ↘ combined | ↗ 25 ms rise |  |
| ↘ 37 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 96 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 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 | 362 Hz | ≤ 10 % brightness setting |     |
The display backlight flickers at 362 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 362 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 8706 (minimum: 5 - maximum: 343500) Hz was measured. | |||

如果你期待XPS 15是一款无论何时何地都能提供高端性能的话，大概会以失望告终。XPS 15不仅在使用电池时处理器频率会降低到1.6 GHz，同时有些卡顿，这显然难以让需要性能的用户满意。在多项测试软件中系统无法及时识别连接上了电源适配器，因而处理器无法运行在2.8 GHz的频率，让人十分郁闷。我们因此在它的总分里减去了一分。遗憾的是，i5-6300HQ无法完全利用它的性能，至少是在单线程的模式下。
我们测试机型的磨砂全高清屏幕在亮度和对比度方面表现优秀。对sRGB色域近100%的覆盖也是一大优势。不过我们并不太喜欢它出场状态（对于专业用户）不太准确的色彩。这让我们感到十分遗憾，因为只需校对一下它就可以得到改观。屏幕闪烁只会在最低亮度下出现，因此不会造成太大问题。
我们之前提到了它的电池续航时间。9小时的续航——在最低亮度待机状态下——也并不算特别惊艳。这款笔记本电脑在上网浏览测试中实现了5.5小时的续航，属于中规中矩，可以满足大部分情况的需要。相比之下，Apple的MacBook Pro 15 Retina在（Mac OS）同样的测试中可以多坚持约两个小时。
如果你想要更长的电池续航时间，那么或者是必须购买售价更高、采用固态硬盘并搭配84 Wh电池的机型，或者单独购买一块84 Wh的电池。售价相对“较低”的非传统硬盘型号（例如全高清＋i5＋128 GB固态硬盘）很遗憾无法在戴尔网站购买；而高容量的机型则搭配了4K触控屏幕和酷睿i7处理器。
它的散热噪音控制不算是优势，因为XPS 15需要大幅降低显卡和处理器频率来控制压力测试时产生的热量，不过它的机身仍然变得很热。我们的测试接近于极限情况，并不代表实际使用状态，不过对于需要高性能的用户有一点是很明确的：在处理器和显卡的同时高负载下，它们都会降频，而我们所说的不是在使用电池的情况下。这个问题不是来自电源适配器而是95度的温度限制。不过我们可以让游戏玩家稍微安心：GTX 960M的性能在游戏测试中与其它采用同型号显卡的笔记本电脑区别不大。
是的，戴尔XPS 15(9550)是一台精致的多媒体笔记本电脑。不过，对它一些技术细节的仔细审视影响了这台XPS给我们的整体印象。
我们喜欢它十分平衡的扬声器，不过它的麦克风很难满足我们的期待。录音的效果受到或强或弱的噪音的影响。
混合式的硬盘是在性能和存储容量之间的成功取舍。他的读取速度无法和真正的固态硬盘相比，不过明显高于迟缓的传统硬盘。戴尔的“Raid array”技术在应用程序性能上十分出色，甚至可以和真正的固态硬盘系统相媲美。普通的缓冲式混合硬盘还无法做到这一点。
