Display Response Times

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
27.2 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 11.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 55 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
35.6 ms ... rise ↗ and fall ↘ combined↗ 18.4 ms rise
↘ 17.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 25 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 19690 Hz100 % brightness setting

The display backlight flickers at 19690 Hz (Likely 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 19690 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8568 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Dell XPS 13 i7-8550U

戴尔的这台配备第八代Kaby Lake-R处理器的XPS 13,性能增加的同时,温度也在增加。因而,该机被设计成可以在更高的核心温度下运行的机器。而且尽量避免对用户的使用造成负面影响,或是使得表面温度达到让人不舒服的程度。我们的测试或多或少地支持了这个观点,因为在强负载的下,核心温度停止在90℃,同时不需要风扇达到更高的转速。键盘某些部分的表面温度会略微升高,但掌托和触控板的温度不会不舒服。

除了CPU性能的显着飞跃和GPU性能的小幅提升之外,这款XPS 13没有给我们带来更多的惊喜。我们之前的评价现在依然有效。有一个理由,去购买XPS 13 i7-7560U 机型而不是i7-8550U。那就是Iris graphics比UHD Graphics 620运行速度快出18%,但是CPU性能却要低40%左右。对于需要高内核数量来运行应用程序的人,应该会喜欢这款新的Kaby Lake-R XPS 13。由于稳定状态下的2.5 GHz时钟速率与3.7 GHz的频率相差甚远,所以仍有改进空间。那么,看看其他具有相同CPU的超极本在未来几周的表现,将会变得很有趣。

XPS 13这台小型笔记本再次成为非常有竞争力的产品。 而我们希望酷睿超频功能有更好的可持续性,而且性能提升也能与广告一致。
