Breve Análise do Portátil Lenovo ThinkPad E580 (i7-8550U, RX 550)

Benjamin Herzig (traduzido por Ricardo Soto), 03/08/2018

Maior é melhor. Pouco depois de analisar o ThinkPad E480 seu irmão maior, o E580, chegou ao nosso laboratório. Será que o acessível portátil empresarial de 15,6 polegadas sofre dos mesmos problemas de aquecimento que o E480? Vamos descobrir?

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
32 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 14 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. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined↗ 26 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 0.9 (minimum) to 636 (maximum) ms. » 78 % of all devices are better.
This means that the measured response time is worse 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 25000 Hz ≤ 90 % brightness setting

The display backlight flickers at 25000 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 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8895 (minimum: 43 - maximum: 142900) Hz was measured.

E480 com dGPU não conseguiu chamar nossa atenção e garantir uma recomendação, apesar de sua fenomenal relação de preço-desempenho, principalmente porque esquentou muito, um problema que o E580 maior também sofre, porém em um grau um pouco mais baixo.

O E580 compartilha muitas das qualidades de seu irmão menor, como o excelente teclado, a combinação de TrackPoint e touchpad, sua capacidade de atualização exemplar, e sua decente tela IPS (fora a cobertura do espaço de cores). Além disso, a carcaça foi melhorada em ralação à do E570.

No entanto, toda moeda tem dois lados, e o E580 também compartilha muitas de suas desvantagens  com o seu irmão menor. Uma das principais é o SDD bastante lento que conseguiu ser ainda mais lento. Além disso, o E580 possui um leitor microSD em vez de um leitor de cartões SD de tamanho normal, e ainda não entendemos por que a Lenovo tomou essa decisão. O gerenciamento do aquecimento é deficiente, e as temperaturas da superfície de até 60 °C (~140 °F) ainda são altas demais. Pelo menos o ventilador melhorou um pouco, o que já é um grande ponto positivo. Infelizmente, este aparente beneficio paga um preço alto: O desempenho da CPU  é decepcionante, por dizer pouco. O i7-8550U nominalmente mais veloz, resultou ser mais lento que o i5-8250U do  E480. Embora ainda seja muito mais veloz que a CPU dual-core do seu predecessor, atualizar o E580 do i5 para o i7 não faz sentido algum. A duração da bateria é tão medíocre quando a do E480, e a garantia do portátil se limita a 12 meses. E finalmente, descobrimos o desempenho da GPU se afogando fortemente com a bateria.

O E580 certamente esquenta menos que o seu irmão menor. Por isso, considerando a sua mais que decente relação de preço-desempenho, merece nossa recomendação.

Apesar de todos seus pontos negativos, o E580 merece nossa recomendação, no entanto, não sem uma advertência. Somente vale a pena comprar os SKUs i5, e usa-los sobre suas pernas pode se tornar um problema muito quente. Deixando os problemas de lado, o E580 é um portátil de escritório capaz de lidar com jogos, com ambições de multimídia.
