Breve Análise do Portátil Guru Mars K (Clevo P775DM3-G)

Florian Glaser (traduzido por Ricardo Soto), 10/27/2017

Pico de energia. Embora haja uma tendência para portáteis de jogos mais leves e mais finos (mas muitas vezes também muito barulhento e quente), a Gaming Guru agora apresenta um sério substituto de desktop com o Mars K, que oferece todas as virtudes de um PC de desktop. Será que o portátil de 17 polegadas tem alguma chance em contra dos rivais estabelecidos da Acer, MSI, e Asus?

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
26.4 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 12.4 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. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
37.6 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 18.8 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. » 32 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.5 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 133300 Hz95 % brightness setting

The display backlight flickers at 133300 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 95 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 133300 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 8586 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Guru Mars K. Test model courtesy of Gaming Guru.

O Guru Mars K é a escolha certa se você estiver procurando um substituto de desktop poderoso com excelente capacidade de manutenção/atualização e se o chassi volumoso e pesado não for um problema.

O portátil de jogos de 17 polegadas está cheio de hardware de gama alta. Uma combinação de Core i7-7700GeForce GTX 1080, e SSD PCIe lida com qualquer aplicativo convencional com facilidade. Você também recebe bons dispositivos de entrada (teclado de três zonas com iluminação RGB!), sistema de som poderoso e muitas portas.

A tela IPS também é convincente, pelo menos se você pode viver com a resolução e a frequência (apenas 1080p @75 Hz). Não encontramos problemas com os ângulos de visão, precisão de cores, luminância ou contraste.

Os inconvenientes incluem o enorme consumo de energia e a limitada duração da bateria, mas estes não são pontos tão negativos para um substituto de desktop. O controle da ventoinha e o alto ruído do sistema sob as cargas de trabalho 3D são muito mais irritantes.

O Mars K ainda assegurará uma boa posição em nossa próxima atualização do Ranking dos Top 10.
