戴尔 Latitude 14 E7470 超级本简短评测

Name: Dell Latitude 14 7000 Series E7470
Brand: Dell

新高分。 一台笔记本电脑很少会得到如此的高分。昂贵的WQHD机型可以满足超高的期待吗？不留情地说，它的电池续航让我们有些失望，不过这款14寸设备的其它方面都可以成为旗舰商务便携笔记本的里程碑。

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
27 ms ... rise ↗ and fall ↘ combined	↗ 7 ms rise
27 ms ... rise ↗ and fall ↘ combined	↘ 20 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 0.1 (minimum) to 240 (maximum) ms. » 63 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined	↗ 15 ms rise
48 ms ... rise ↗ and fall ↘ combined	↘ 33 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 80 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 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 17924 (minimum: 5 - maximum: 3846000) Hz was measured.

In review: Dell Latitude E7470. Test model courtesy of Dell Germany

戴尔坚持着它的理念，没有为这台商务超级本的新版本减少任何功能。这台14寸设备工艺上乘，可以满足商务以及通常使用的需要。不过镜面的屏幕则非如此，它在日光下会造成十分影响使用的反光。WQHD屏幕的优秀表现则弥补了这个缺憾，在室内它显得特别养眼。出色的输入设备对于高端的Latitude来说必不可少，E7470也没有让我们失望。安全管理也是如此，一台笔记本电脑很少会支持如此多的（可选）安全功能。它的可维护性也值得赞誉；只需打开底盖你就可以更换升级所有的组件。

它唯一的短板是续航时间，5小时46分钟的无线上网对它来说就是极限了。这很难满足我们对一台售价2300欧元（约16952人民币）的设备的期待。搭配高清或全高清屏幕的型号将会提供相比4K型号稍长的续航时间。

可能它最强的竞争者是惠普的EliteBook Folio 1040 G2，不过它搭配磨砂全高清屏幕的型号售价还高出了200-300欧元（约1474到2211人民币）。它的电池续航稍长，不过接口较少。如果你想节省一些预算，IGP版本的联想 ThinkPad T450s也值得考虑；配置相当的型号起售价约1850欧元（约13635人民币）。如果考虑磨砂全高清屏幕型号的话，E7470和T450s的性价比十分接近。

2016/04/02更新：增加ThinkPad T460s全高清IPS和T460sWQHD屏幕型号到比较列表中。
