In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 64 % 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)
Screen flickering / PWM detected | 26040 Hz | ≤ 40 % brightness setting | |
The display backlight flickers at 26040 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 26040 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured. |

Pros
Cons
今年更新的联想 ThinkPad T570 从很多角度来说都是一台很出色的商务本,但仍存存在一些造成不足的缺陷,希望能够尽快被解决。
我们真的很喜欢更加紧凑的机身。联想在T系列的最新型号上回到了黑色的外壳设计,并且使其更加小巧。这点在窄边框上十分明显。稳定性和制造质量并没有为紧凑的机身做出任何妥协。但是,试图接触内部组件是很复杂的,这点已经在同系列更小的T470机型上得到体现。
其他优点包括出色的输入设备,尽管由于新的外壳设计有些按键比原来窄,其输入体验依旧没有什么可以批评的地方。触摸板相对于上代也有所改进。联想在其余方面也没有作出任何的妥协,包括安全特性,无线网络性能,接口多样性,以及电池运行时间。
出色外壳,连接性,以及出色的输入设备,不过有中庸的全高清屏幕及偶然的性能下降。联想 ThinkPad T570 只要经过一些改进就能成为一台极为出色的商务本。
有一个不足之处仍未改变,由于联想仍使用了一个很平庸的全高清面板,它基于IPS并且比起它的上一代ThinkPad T560(约250尼特)亮。但它比起它的其他竞争者来说毫无胜算,色域也受到限制。
我们对偶尔的性能下降及发热情况感到很惊讶。因为性能问题很少发生,我们认为应该是软件问题。理论上来说,ULV处理器应该是能够发挥所有的性能的,但有时它无法全速运行而且将会在短时间后触及温度保护线。电池供电下显著的性能衰减并没有必要,因为处理器本身甚至连基础频率都无法维持。我们希望这个问题很快能够被解决。就像T470s一样,我们因为上述问题在最终评分当中扣去了3分,因此T570在当前状况下并没能达到“十分出色”的评级。
