Breve Análise do Portátil Lenovo Ideapad 720S-13IKB (i5-8250U, UHD 620)

Mike Wobker (traduzido por Ricardo Soto), 02/08/2018

Desempenho de escritório ultra móvel. A Lenovo chama o novo Ideapad 720s de um "pacote potente de alto desempenho e elegante". Mesmo que não o chamaríamos exatamente isso, o desempenho ainda é impressionante para um portátil com uma espessura de apenas 13 mm (~0,51 pol.). Descobrimos no nosso relatório de teste o que exatamente você pode esperar do 720 em suas várias configurações.

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
25 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 11 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 0.8 (minimum) to 240 (maximum) ms. » 39 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
35 ms ... rise ↗ and fall ↘ combined↗ 17 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 0.9 (minimum) to 636 (maximum) ms. » 25 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.4 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 131 Hz ≤ 90 % brightness setting

The display backlight flickers at 131 Hz (Likely 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 131 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8882 (minimum: 43 - maximum: 142900) Hz was measured.

O Ideapad 720s da Lenovo é um portátil muito leve e ultra  fino para o trabalho de escritório rotineiro. Como um dos poucos dispositivos em nosso teste, o Ideapad 720s é capaz de manter seu desempenho de forma consistente e sem quedas. Mesmo em condições extremas, o bom resfriamento garante que o sistema possa continuar a ser utilizado. No entanto, as opções de manutenção são limitadas, e a Lenovo também se concentrou apenas nas conexões mais essenciais. Mas graças às conexões Thunderbolt, todas as portas necessárias podem ser fornecidas pelo periférico correspondente.

Com o Lenovo Ideapad 720, os compradores recebem um portátil muito fino e leve, que sempre estará lá, mas nunca no caminho durante a vida cotidiana.

Nas ofertas atuais, o Ideapad 720 pode ser comprado com uma CPU Kaby Lake da 8ª geração, sem hesitação. No entanto, os compradores devem seguir suas próprias preferências ao decidir se os modelos com os processadores Ryzen 5 2500U da AMD ou os processadores Kaby Lake da 7ª geração, valem a pena, em termos de preço.
