Breve Análise do Lenovo Ideapad 720S-15IKB (i7-7700HQ, GTX 1050 Ti Max-Q, SSD 512 GB)

Oddball multimídia. A Lenovo equipou o primeiro portátil de 15 polegadas de sua série 700 com hardware exótico, incluindo um i7-7700HQ com um TDP reduzido para 35 watts e um 1050 Ti Max-Q. O concorrente tem muito a oferecer - uma ótima tela, bateria de longa duração, mas a proverbial mosca na sopa pode ser um obstáculo para algumas pessoas.

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 0.1 (minimum) to 240 (maximum) ms. » 55 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
34 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 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 ≤ 40 % brightness setting

The display backlight flickers at 25000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

Mesmo depois de algumas semanas na companhia do Lenovo Ideapad 720S-15IKB, ainda achamos sua configuração de hardware um tanto estranha, mesmo que seja totalmente sensata. Um i7-7700HQ reduzido para um TDP de 35 watts tem valor de curiosidade, e considerando os problemas do sistema com a regulação térmica, ficamos imaginando se a Lenovo afogou a CPU por simples necessidade. Apesar dessa estranheza, o poder de desempenho do processador é mais do que suficiente para aplicativos pesados e multitarefa intensiva. A CPU nunca atua como gargalo - a versão Max-Q minimamente afogada da Nvidia GeForce 1050 Ti desempenha esse papel, principalmente na renderização de jogos com alta demanda de hardware.

Para um dispositivo dessa classe, inclusive em comparação direta com outros portáteis que cobrimos nesta análise, a incomum seleção de portas será, sem dúvida, um empecilho para muitos compradores em potencial. Forçar os usuários a carregar adaptadores que precisam ser adquiridos separadamente é uma maneira infalível de perder clientes. Não sabemos explicar a ausência de uma conexão HDMI e/ou DisplayPort separada, já que certamente há muito espaço disponível. As desvantagens muito menos importantes incluem a recepção inferior de WLAN e o bleeding da tela, que só é visível quando o conteúdo da imagem é muito escuro.

Embora o Lenovo Ideapad 720S-15IKB seja um dispositivo atraente na maioria dos outros aspectos, sua regulação térmica problemática e, acima de tudo, sua falta de conexões físicas nos deixam sem vontade de recomendá-lo.

 

No lado positivo, podemos enumerar: A carcaça discreta, porém sólida e ergonômica, os recursos de segurança atualizados, a boa tela e, não menos importante, o modo de economia de energia do sistema e comportamento silencioso - sem esquecer a ampla autonomia da bateria com muitas reservas para o futuro. Embora consideremos o Lenovo Ideapad um sucesso geral - conforme indicado por nossa classificação de 87%, apenas um pouco abaixo de um "muito bom" - mais do que qualquer coisa, a falta de conexões nos impede de fornecer ao dispositivo nosso selo de recomendação. Por outro lado, se você fizer quase tudo sem fio, de alguma forma se antecipar as portas disponíveis, ou não se incomodar com a ideia de carregar adaptadores extras, então o Ideapad ainda pode ser uma boa escolha para você.
