Breve Análise do Portátil Lenovo ThinkPad X280 (i5-8250U, FHD)

Benjamin Herzig (traduzido por Ricardo Soto), 03/13/2018

Mini Carbon. Com um novo design e uma carcaça claramente mais fina, a Lenovo está tentando tornar sua série ThinkPad X tradicional de 12 polegadas, mais atraente. Nesta análise, explicaremos por que essa abordagem funciona bem e quais recursos perdemos, apesar das outras melhorias.

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
29.6 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 13.2 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. » 72 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.7 ms).
       Response Time 50% Grey to 80% Grey
40 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 18 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. » 44 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.1 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8801 (minimum: 43 - maximum: 142900) Hz was measured.

O X280 é provavelmente o redesenho mais abrangente da geração atual de ThinkPads, um fator que nos emociona sobre esse dispositivo. É um portátil conceitualmente diferente do que o ThinkPad X270, que pode assustar alguns de seus fãs. No geral, o X280 é um portátil melhor do que o antecessor.

O aspecto mais importante deste novo design é a carcaça, que é significativamente melhor que a do seu antecessor. A mudança do material de plástico de fibra de vidro para magnésio e fibra de carbono funcionou em termos de redução de espessura e peso. O X280 pesa aproximadamente o mesmo que o X1 Carbon. Essa redução de peso mudou o anacronismo do X270, um portátil de 12 polegadas, mais grosso e pesado do que seus irmãos de 14 polegadas. A carcaça não é apenas mais fina e mais leve, mas também mais fácil de usar, pois a Lenovo removeu os grampos irritantes e que quebravam facilmente da parte inferior. Além disso, a Lenovo resolveu a maioria dos outros problemas que experimentamos com o X270. O ventilador funciona menos, o dispositivo funciona mais frio, o consumo de energia melhorou e a tela é mais brilhante. O X280 manteve a tradição ThinkPad de ter excelentes E/S, com o menor ThinkPad finalmente suportando Thunderbolt 3. Melhor ainda e ao contrário de seus antecessores, o X280 se beneficia do potencial máximo do desempenho da GPU, graças à sua RAM de dois canais.

Onde há pontos positivos, também há negativos, e os negativos ocasionalmente superando os positivos. Curiosamente, os pontos fracos do X280 são aqueles que louvamos no X270. O X280 não é tão flexível quanto o antecessor sem a bateria PowerBridge removível extensível, embora a decisão de omitir a porta Ethernet RJ45 em um dispositivo empresarial é difícil de entender. A redução de um slot de cartão SD para microSD para economizar espaço é compreensível, mas seu posicionamento e acessibilidade não são. A RAM também é vítima de economia de espaço, com a Lenovo optando pela RAM soldada à placa-mãe, em vez da RAM removível, que a concorrência continua a oferecer. Uma desvantagem adicional está relacionada à forma como o X280 gerencia o desempenho da CPU. Normalmente, quando uma CPU baixa sua velocidade devido a altas temperaturas, essa velocidade retornará ao seu estado anterior, uma vez que as temperaturas caírem. Este não é o caso com o X280, com a velocidade permanecendo baixa mesmo quando as temperaturas caíram. Isso pode ser corrigido com uma atualização do BIOS, mas ainda não houve notícias sobre se a Lenovo planeja resolver isso. Além disso, a CPU é afogada com a bateria, no entanto, a Lenovo pode ter feito isso intencionalmente. Esperamos mais do que a média de espaço de cores pobre, uma vez que o X280 é um portátil tão caro. Este é um ponto em que criticamos o X270 e o conjunto mais amplo de portáteis da classe executiva também. Por fim, a Lenovo provavelmente poderia ter equipado o X280 com uma tela de 13,3 polegadas, dado os marcos largos que a tela de 12 polegadas possui.

Se você pode sobreviver sem suporte de ethernet dedicado e uma bateria removível, o X280 é um pacote muito melhor do que o modelo do ano passado, e é por isso que o recomendamos.

Recomendamos o X280 apesar das críticas porque, em geral, é simplesmente um subportátil bem sucedido. O X280 é muito mais econômico que o X1 Carbon 2018, tornando  a Versão Campus uma opção atraente para estudantes. A concorrência também possui alguns modelos interessantes, como o Dell Latitude 7290 e o HP EliteBook 830 G5, que ainda estamos para testar. Em algumas áreas, esses competidores superaram o X280, como a inclusão de uma porta Ethernet e RAM expansível. O X280 tem, como é o caso dos ThinkPads, E/S incomparável, e é o mais leve dos três portáteis. Embora recomendamos o Lenovo ThinkPad X280, os potenciais compradores devem fazer sua escolha com base em suas próprias necessidades e preferências.
