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
26 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 12 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. » 59 % 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
36 ms ... rise ↗ and fall ↘ combined↗ 18 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 0.165 (minimum) to 636 (maximum) ms. » 46 % of all devices are better.
This means that the measured response time is similar to 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 128000 Hz ≤ 90 % brightness setting

The display backlight flickers at 128000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 128000 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 8774 (minimum: 5 - maximum: 343500) Hz was measured.

Pro

+ Incrivelmente leve
+ Muito fino
+ Marcos muito estreitos

Contra

- Conectividade pobre
- Capacidade de manutenção pobre
- RAM apenas single-channel
- Sistema de resfriamento abaixo do esperado

Nossa análise mostra claramente que, ter um design de portátil existente e trocando a CPU Intel por uma AMD Ryzen 5 2500U não dá certo. Se a Lenovo tivesse gasto algum tempo e esforço para adaptar a solução de resfriamento à nova CPU AMD, o IdeaPad 720s baseado em Ryzen poderia ter se tornado uma verdadeira alternativa aos processadores Core da 8ª geração da Intel.

O IdeaPad 720s baseado em AMD é um portátil sólido e poderoso, frustrado pela solução de resfriamento terrivelmente pobre e inadequada.

Ainda assim, o SKU AMD analisado do IdeaPad 720 da Lenovo continua a ser um portátil de escritório decente com poder suficiente para tarefas diárias de escritório e desafios multimídia básicos. Esperávamos um melhor desempenho do que o oferecido pelo SKU Intel, recentemente revisado; infelizmente, foi vítima da falha da Lenovo em adaptar o dispositivo à CPU da AMD corretamente.
