戴尔 Latitude 5580 (i5-7200U, 高清) 笔记本电脑简短评测

Name: Dell Latitude 5580
Brand: Dell

纵向更新。 Latitude系列已经开始逐步淘汰专有的E-port，转而支持功能更多的雷电3接口。否则，和E5570系列比变化就不大了。

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
29.6 ms ... rise ↗ and fall ↘ combined	↗ 21.2 ms rise
29.6 ms ... rise ↗ and fall ↘ combined	↘ 8.4 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. » 77 % 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
30 ms ... rise ↗ and fall ↘ combined	↗ 19.2 ms rise
30 ms ... rise ↗ and fall ↘ combined	↘ 10.8 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. » 36 % of all devices are better. This means that the measured response time is similar to 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

201.6 Hz

≤ 99 % brightness setting

The display backlight flickers at 201.6 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 201.6 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured.

- 没有E-port

对比我们现有的对于E5550 / E5570的评测，Latitude 5580并没有什么特别之处。其电池续航长，维护方便，配置选择范围广泛，Linux认证且键盘舒适。对于大多数类型的办公工作，该机是一个有吸引力而且多功能的商务笔记本。

价格是5580的主要考虑因素。虽然像我们这样的入门级配置可以在起步价是700美元左右，但诸如智能卡读卡器，雷电3，WWAN，NFC和指纹识别等可贵功能将使起步价格突破1000美元。此外，我们建议避免可怕的高清显示屏配置，而是选购全高清版本，但是全高清版本的底价是1100美元。配置更快的HQ级处理器起价为1000美元，同时只包括4 GB的运行内存，以及上述的高清显示器，甚至不包括固态硬盘。为了充分利用Latitude 5580所提供的功能，用户需准备支付比阉割的入门级配置机更多的费用。

我们可能会在不久的将来查看Latitude 5580的高端配置机，以更好地了解该机型所能提供的一切。一个HQ级处理器的TDP是U级处理器的两倍以上，全高清面板几乎肯定能提供更好的体验。这些要求更高的组件如何影响电池续航，风扇噪音和性能很值得关注。
