Breve Análise do Portátil Microsoft Surface Book 2 (15", i7, GTX 1060)

Andreas Osthoff (traduzido por Ricardo Soto), 02/21/2018

Agora, em um formato de 15 polegadas - Análise ao vivo. Após alguns meses de atraso, a versão maior do Microsoft Surface Book 2 está finalmente disponível na Alemanha. Nós obtivemos nosso dispositivo de teste precisamente no lançamento de vendas e agora o colocamos à prova. Estamos especialmente ansiosos para examinar o gerenciamento de energia dos componentes mais poderosos, porque já vimos estrangulamentos nesta área no modelo mais pequeno.

Size Comparison

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 21930 Hz ≤ 50 % brightness setting

The display backlight flickers at 21930 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 21930 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 8882 (minimum: 43 - maximum: 142900) Hz was measured.

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
22.4 ms ... rise ↗ and fall ↘ combined↗ 11.2 ms rise
↘ 11.2 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 25 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
37.6 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 19.6 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. » 34 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.4 ms).

In review: Microsoft Surface Book 2. Review device provided courtesy of: notebooksbilliger.de

Após as primeiras horas com o novo Surface Book 2 15, conseguimos desenhar muitos paralelos entre ele e seu irmão menor. O novo controle deslizante de desempenho no Windows 10, mais uma vez, tem bastante impacto no ruído do ventilador. O processador no tablet resfriado de forma ativa. No entanto, esperávamos mais da solução de resfriamento melhorada (em comparação com o modelo de 13 polegadas). 

A tela é mais brilhante, mas tem mais problemas com bleeding de tela e utiliza PWM para o controle de brilho. Além disso, a calibração da fábrica não é muito boa. De acordo com nossos primeiros testes, a bateria maior faz um bom trabalho para compensar o aumento do consumo de energia do painel maior e, ao navegar na web, você pode esperar mais de dez horas de duração da bateria.

Vamos realizar os testes e benchmarks restantes nos próximos dias. Ao fazê-lo, nos concentraremos principalmente nos impactos no desempenho e no consumo de energia dos vários perfis de energia.
