戴尔G7 17 7790 (i7-8750H, RTX 2070 Max-Q) 笔记本电脑评测

现已装配蓝色热管。

戴尔推出的最新中档游戏笔记本电脑定位于入门级G3系列和高端Alienware之间。 即便如此，该系统相对较重，甚至比17.3英寸的Alienware m17还要重几百克。

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
12 ms ... rise ↗ and fall ↘ combined↗ 6.8 ms rise
↘ 5.2 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 28 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (20.9 ms).
   ↔    Response Time 50% Grey to 80% Grey
17.2 ms ... rise ↗ and fall ↘ combined↗ 7.6 ms rise
↘ 9.6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 28 % of all devices are better.
This means that the measured response time is better 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured.

戴尔G7 17 7790笔记本电脑评测
戴尔G7 17 7790笔记本电脑评测

戴尔G7 17 7790与Alienware m15和m17具有许多相同的优点和缺点。性能非常出色，特别是在长时间保持可靠的Turbo Boost水平时，尽管这是以CPU的高温为代价的。大个的的风扇与较轻且通常更安静的联想Y740相比就没那么讨喜了，后者配备了与戴尔相同的CPU和GPU选项。重型游戏笔记本电脑是可以理解的，但它们应该更安静，以弥补重量上的缺陷，不幸的是G7 17在两个方面都没做好。

尽管如此，这台电脑还是有许多讨喜的地方的。标配的144 Hz面板，易于维修，扬声器和多种接口选项给人留下了坚实的第一印象，即使机身看起来不像许多竞争对手那样帅气。但是，如果您打算经常在旅途中使用17.3英寸游戏笔记本电脑，那么较轻的MSI GS75或Acer Predator Helios可能是更明智的选择。

虽然缺点列表很短，但它们非常关键。强大的性能需要吵闹的风扇和重型机身做靠山，比起经常出差的游戏玩家这更适合家庭游戏玩家。
