Benjamin Herzig, 👁 Sebastian Jentsch (traduzido por Ricardo Soto), 09/11/2019

Profissional para pequenas empresas com duração de bateria excepcional As CPUs Intel Whiskey Lake chegaram à série Dell Latitude. O Latitude 7300 redesenhado também possui um e nos surpreendeu com sua capacidade de atualização decente (RAM) e bateria de longa duração. Infelizmente, nem tudo o que reluz é ouro, e o desempenho da CPU do portátil foi o obstáculo.

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
27 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 13 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. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25 ms).
       Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 21 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. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.8 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9418 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Dell Latitude 7300. Review unit courtesy of Dell.
In review: Dell Latitude 7300. Review unit courtesy of Dell.

A Dell redesenhou seu Latitude de 13,3 polegadas sem mudar muito. Pelo menos no mais escuro dos dois modelos, com sua carcaça de fibra de carbono que tivemos em análise. O SKU de alumínio parece muito diferente do seu antecessor.

A carcaça compacta de alta qualidade é um dos destaques do Latitude, assim como o teclado confortável. A tela está equipada com uma camada de toque que permite entradas adicionais. O leitor de cartões microSD é facilmente acessível e incrivelmente rápido. Além disso, o Latitude possui várias portas e recursos de segurança. Também é facilmente atualizável graças a dois slots de RAM, um slot WWAN livre e um modem Wi-Fi com soquete. Ele vem com 3 anos de garantia no local/em casa e funcionou por quase 11 horas com bateria em nosso teste de Wi-Fi.

Uma de suas principais ressalvas é o touchpad. Se sente barato e não gostamos ou desfrutamos de sua superfície plástica áspera. Dado que o Latitude não possui um TrackPoint, os usuários serão forçados a recorrer a mouses externos. Também não gostamos muito da porta de carregamento proprietária e teríamos preferido uma segunda porta USB-C ou Thunderbolt 3 com fornecimento de energia. A Ethernet está ausente, e a tela supostamente mate acabou sendo sendo semi refletiva. Esperávamos que a Dell fosse mais precisa em suas especificações em relação a esses detalhes.

O desempenho da CPU foi bastante ruim e pior do que no próprio antecessor do Latitude 7300. Aqueles com a CPU i7 não estão obtendo o desempenho esperado. Um problema inaceitável para um portátil desse preço.

O ruído agudo do ventilador foi outra desvantagem, embora o ventilador não tenha sido particularmente alto em geral. E por último, mas não menos importante, teria sido bom ter uma opção de tela mais brilhante disponível.

Um desempenho geral sólido com um ponto crucial: A CPU Whiskey Lake acabou sendo mais lenta que o processador do antecessor.

Se você deve considerar isso como um obstáculo para a compra, depende de você. No lado positivo, o portátil empresarial Dell Latitude 7300 oferece uma excelente duração da bateria e excelente capacidade de atualização.
