戴尔XPS 15 9570（i9-8950HK, 4K UHD，GTX 1050 Ti Max-Q）笔记本电脑评测

性能太强了？

性能太强了？在评测过酷睿i5和i7版本之后，我们终于对XPS 15 9570的i9版进行了深入的评测。简而言之，结论就是，买家更应该花钱在更大内存，更多存储空间和更好的显卡上，而不是去升级i9的CPU。

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
31.6 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 13.6 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. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (20.5 ms).
   ↔    Response Time 50% Grey to 80% Grey
52.4 ms ... rise ↗ and fall ↘ combined↗ 27.6 ms rise
↘ 24.8 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. » 88 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.1 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 1000 Hz ≤ 25 % brightness setting

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 25 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8350 (minimum: 5 - maximum: 343500) Hz was measured.

同样的i9-8950HK在厚重的微星GT75中性能强了许多不是没有原因的。为了充分发挥它的性能，散热方案必须够给力，以在合理的温度下维持睿频。

i9版XPS 15似乎又是一个在仅仅适合i7的机身中强塞i9处理器的经典例子。我们在ZenBook UX580和i9 Eurocom Q8上认清了这一点，i9 XPS 15也不例外。理论上来说，i9-8950HK性能比i7-8750H要强25%，但在XPS 15上却只有10%的提升，要知道，i7版XPS 15相较i5版提升了50%。

“我们的建议是选择i7版本，然后花钱升级内存，硬盘和显卡，以得到有效的性能提升。”
