惠普 ProBook 455 G3 T1B79UT 笔记本电脑简短评测

实惠AMD商务本。 AMD设备比搭载同样配置的英特尔处理器的ProBook 450便宜至少200美元。可惜,当与你的标准型超低电压版酷睿ix 处理器对比时,它的性能和电池续航有着明显的不足。

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
30.8 ms ... rise ↗ and fall ↘ combined↗ 11.2 ms rise
↘ 19.6 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 (21 ms).
       Response Time 50% Grey to 80% Grey
45.2 ms ... rise ↗ and fall ↘ combined↗ 23.2 ms rise
↘ 22 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. » 75 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 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 198.4 Hz ≤ 99 % brightness setting

The display backlight flickers at 198.4 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 198.4 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 8774 (minimum: 5 - maximum: 343500) Hz was measured.

Verdict

In review: HP ProBook 455 G3 T1B79UT
In review: HP ProBook 455 G3 T1B79UT

用于笔电的AMD Carrizo处理器具备可定制热设计功耗,本应算是极具通用性的。然而它的性能表现却比之前的第三代酷睿i5-4200U慢得多。相比较早前在英特尔硬件上搭载的 HD Graphics 520或HD Graphics 5500显卡,集成的Radeon R6显卡也存在着类似的问题。

如果ProBook 455运行时明显地更为安静和持久,那么AMD的性能短板也会变得可以接受。然而事与愿违。机器表面的温度并没有更低,电池续航甚至比预期的更短。

撇开处理器不谈,ProBook 455是良好的低工作负载准系统解决方案。它在概念和设计上都十分平庸,我们希望未来的修订版本至少能为硬件添加一些功能,包括USB-C以及指点杆选项。

当较老的英特尔酷睿ix处理器比最新AMD处理器提供的性能更高且续航更长时,我们很难推荐采用Carrizo平台的机型。
