雷蛇 Blade Stealth (i7-7500U) 笔记本电脑简短评测

成功新品。 这台在CES正式发布的为游戏玩家设计的亚笔记本电脑得到了英特尔Kaby Lake处理器更新。略高的性能当然总是好事,特别是再能够搭配雷蛇Core外置显卡。最好的消息是,雷蛇目前在德国和其他许多欧洲国家正式发布了新的Blade Stealth和雷蛇Core。

Display Response Times

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
33.4 ms ... rise ↗ and fall ↘ combined↗ 13.2 ms rise
↘ 20.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.1 ms).
       Response Time 50% Grey to 80% Grey
37 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (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 (38.2 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 200 Hz ≤ 30 % brightness setting

The display backlight flickers at 200 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9716 (minimum: 5 - maximum: 151500) Hz was measured.

In Review: Razer Blade Stealth with Intel Kaby Lake
In Review: Razer Blade Stealth with Intel Kaby Lake

雷蛇的最新Blade Stealth几乎克服了前代机型最大的缺点:一般的电池续航。这台新设备的8到13小时续航表现完全可以让用户在一整天的时间内(根据使用需要)远离插座。它的机身没有变化,高端设计加上工艺品质和质感完全可以和Apple的MacBook系列抗衡。遗憾的是它的黑色磨砂表面比较容易沾染指纹,同时十分难以清除。

得力于Kaby Lake处理器和更大容量的电池,Blade Stealth现在不用再在其他亚笔记本电脑面前抬不起头了。雷蛇Core外置显卡也是个让人期待的搭配选项,不过即使没有它,Blade Stealth自身也是一台十分成功的笔记本电脑。

这次我们得到的测试机搭配了QHD+屏幕。这块面板在各方面的表现都十分优秀,完全可以媲美4K屏幕。特别是考虑到较小的12.5寸大小,这块屏幕的在大部分情况下可能都是更好的选择。这个搭配较低分辨率屏幕的配置型号价位也低200欧元(约1505人民币),同时可能也对降低功耗做出了贡献。

它的性能也让我们十分惊喜。这颗处理器的表现十分优秀,即使是在系统负载较高的情况下也十分稳定。Blade Stealth十分适合与雷蛇Core搭配,构建一个强劲的游戏系统。我们将在接下来的评测中提供更多的相关信息。
