Breve Análise do Conversível Lenovo Flex 5 15 (i7-8550U, GeForce MX130)

Allen Ngo, 👁 Allen Ngo (traduzido por Ricardo Soto), 09/11/2018

Não tão flexível. O Flex 5 da Lenovo é um 2-em-1 acessível que parece ótimo pelo preço, com muitas portas integradas. Infelizmente, a tela fraca e o baixo desempenho do Turbo Boost deixam muito a desejar.

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
29.2 ms ... rise ↗ and fall ↘ combined↗ 17.6 ms rise
↘ 11.6 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. » 70 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.8 ms).
       Response Time 50% Grey to 80% Grey
37.6 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 18.4 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. » 36 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.5 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 21190 Hz ≤ 99 % brightness setting

The display backlight flickers at 21190 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 21190 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9331 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Lenovo Flex 5-1570 81CA000RU

O Flex 5 não é para entusiastas ou usuários de desempenho e a Lenovo sabe disso. Em vez disso, o sistema é para o usuário ou estudante de multimídia doméstico que pode simplesmente querer um portátil de 15 polegadas do Windows com recursos de tablet para reprodução de filmes, processamento de texto e jogos casuais ocasionais. Não oferece vatagens significantes sobre o Pavilion 2-em-1Vivobook 2-em-1Envy 2-em-1, ou o mais pesado Inspiron 15 2-em-1 mais que uma opção para a lenta GPU GeForce MX130. Como um conversível familiar, o Flex 5 apenas se encaixa ao preço.

Lamentavelmente, há uma longa lista de cortes de desempenho. A tela muito fraca significa que este é um conversível feito principalmente para uso em interiores e o extremamente limitado Turbo Boost significa que há muitos poucos motivos para comprar o SKU Core i7-8550U quando o mais barato i5-8250U SKU pode se desempenhar quase igual Sua RAM de canal único dificulta ainda mais o desempenho e a solução de resfriamento é embaraçosamente pequena, considerando-se o espaçoso formato de 15 polegadas. Há um amplo espaço vazio ao redor do ventilador, que poderia ter sido utilizado para uma solução de resfriamento maior para reduzir o ruído do ventilador.

O preço inicial de $700 é justo para um sistema sem brilho e honestamente esquecível, enquanto SKUs de ponta podem alcançar mais de $1.000. Recomendamos evitar as opções mais caras, pois seria melhor usar um portátil tradicional bem feito, como o XPS 15 ou gastar um pouco mais no Spectre x360 15. O extremamente fraco Turbo Boost e tela fraca tornam isso uma tarefa difícil.
