Display Response Times
ℹ
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 | ||
|---|---|---|
| 32.4 ms ... rise ↗ and fall ↘ combined | ↗ 18.8 ms rise |  |
| ↘ 13.6 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 87 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 48.4 ms ... rise ↗ and fall ↘ combined | ↗ 27.6 ms rise |  |

| 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. » 82 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

- Desempenho inconsistente a longo prazo
- Afogamento da CPU sob carga
A Dell fez um excelente trabalho com o Latitude 7490, mas principalmente porque fez um excelente trabalho com o 7480. Quase tudo é simplesmente uma transferência do modelo do ano passado. A maior fortaleza que o Latitude 7490 tem sobre o 7480 é a inclusão dos processadores de oito núcleos quad-core da Intel. Apesar de manter o mesmo TDP de 15 W dos processadores anteriores da série U, os processadores Kaby Lake R quase dobram o desempenho de suas respectivas contrapartes da 7ª geração. O Latitude 7490 é um bom exemplo dos ganhos em desempenho de aplicativos a serem obtidos pelo aumento de desempenho em Kaby Lake R, mas também é um exemplo de alguns dos sacrifícios que os novos chips fazem. O afogamento térmico é uma questão importante aqui. Sob cargas pesadas, a CPU é capaz de impulsionar todo o seu potencial, mas apenas por breves momentos.
Seremos francos: se você já possui um Latitude 7480, pode ignorar o 7490. O desempenho adicional da CPU só será visto em tarefas que exigem muito do processador; a menos que seu fluxo de trabalho inclua o uso pesado de planilhas ou outro trabalho pesado da CPU, a atualização do processador não vale o custo de uma nova máquina. No entanto, se você deseja comprar um novo portátil corporativo ou precisar substituir uma máquina que já tem alguns anos, o Latitude 7490 deve ser considerado. A Dell criou uma excelente máquina que rivaliza com os outros campeões da indústria.
