华硕 AsusPro B9440UA (Core i5, 8 GB) 笔记本简短评测

Name: Asus ASUSPRO B9440UA-GV0100T
Brand: Asus

世界上最轻的14寸笔记本。 至少华硕的说法是这样的。因为华硕的广告上说他们最新的1.05kg (2.31lbs)重、15mm (0.59 inches)厚的仅有USB-C的商务本是如此。我们详尽的评测将会表明为了达到这一极限所带来的限制是否值得，以及B9400A作为高便携度商务本其表现如何。

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
30.8 ms ... rise ↗ and fall ↘ combined	↗ 8 ms rise
30.8 ms ... rise ↗ and fall ↘ combined	↘ 22.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 81 % 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
48.8 ms ... rise ↗ and fall ↘ combined	↗ 18 ms rise
48.8 ms ... rise ↗ and fall ↘ combined	↘ 30.8 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. » 83 % of all devices are better. This means that the measured response time is worse 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.

华硕牺牲了所有能在正常的笔记本上找是的接口，仅仅留下了两个USB-C接口，这将让很多用户放弃它。但是，如果不这么做，那么就做不到仅仅15mm的厚度和1.05kg的重量。

尽管它做出了很多的妥协。但它出色的键盘达到了它高售价的标准。而且附带的接口扩展器及保护壳也很让人喜欢。其安全功能反映了其极高的便携度。它是我们这几个月来测试过的最安静的笔记本之一，且其电池续航能力也令人印象深刻。除了接口外，其他在缺点列表上的项目都可以说是微不足道的，如果不是要求太高的话完全可以忽略。

华硕 Pro B9440UA 是一台高便携度的商务本。其注重于无线连接功能而且没有明显的缺点。尽管整体上它给我们留下了很好的印象，它的评分还是和“非常好”失之交臂。

在我们看来，我们所测试的欧洲型号（GV0100T，售价1200美元）是最合理的选择（但如果在大西洋彼岸的话应该多考虑售价为1000美元的配置更好的入门级型号），我们显然很推荐这款笔记本。
