Breve Análise do Portátil Dell Latitude 5280 (7200U, HD)

Allen Ngo (traduzido por Ricardo Soto), 06/09/2017

Pequeno e potente. A Dell criou um chassi significantemente mais leve agora, e a porta E-Port esta se tornando uma coisa do passado. No entanto, a falta do Thunderbolt 3, limita muito as capacidades deste amis recente design Latitude.

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
23.2 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 6 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. » 27 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 20.8 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. » 52 % of all devices are better.
This means that the measured response time is similar to 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 not detected

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: Dell Latitude 5280
In review: Dell Latitude 5280

Um ponto de venda importante da maioria dos portáteis de negócios é a capacidade de conectar facilmente estações docking ou baterias externas. Agora que a série Latitude 5280/5480/5580 deixou de lado o E-Port, o Thunderbolt 3 está se tornando ainda mais crucial para suportar recursos adicionais. Infelizmente o Latitude 5280 carece de ambos e, consequentemente, é menos versátil do que o 5480 e o 5580, embora seja menor e mais portátil. Além disso, a ventoinha do sistema está sempre ativa, o qual achamos desnecessário para um portátil que ostenta apenas processadores classe U. 

Se as desvantagens acima não forem um obstáculo, no entanto, então o 5280 se destaca na maioria das outras categorias. Sua porta USB Type-C ainda será uma saída para DisplayPort de monitores externos e o novo chassi é muito mais leve que o E5270 sem ser notavelmente mais frágil. As durações da bateria já são excelentes na opção de bateria de gama média e preservar as saídas VGA e HDMI deve ser útil em lugares como universidades e da salas de conferência. O desempenho da CPU em particular é impressionante, pois o processador é capaz de manter velocidades máximas do Turbo Boost, mesmo durante cargas de trabalho muito altas.

Recomendamos que evite a muito pobre tela 768p e opte pela opção 1080p mais brilhante, com SSD primários mais rápidos. A melhoria na resolução e no brilho tornará o portátil mais confortável de usar e o investimento vale totalmente se o sistema for usado com frequência sem monitores externos. 

Pode levar algum tempo se acostumar ao teclado um pouco esponjoso, e os usuários com mãos maiores podem querer evitar essa categoria de tamanho especial para digitação pesada. O 5280 é mais para usuários em constante movimento do que algo para estar em um lugar fixo em casa ou no escritório.
