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 detected

1064 Hz

≤ 90 % brightness setting

The display backlight flickers at 1064 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1064 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 8715 (minimum: 5 - maximum: 343500) Hz was measured.

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
34.4 ms ... rise ↗ and fall ↘ combined	↗ 17.2 ms rise
34.4 ms ... rise ↗ and fall ↘ combined	↘ 17.2 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. » 91 % 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 ms ... rise ↗ and fall ↘ combined	↗ 24.4 ms rise
48 ms ... rise ↗ and fall ↘ combined	↘ 23.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 81 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms).

Pro

+ Bom complemento de portos físicos

+ Muito boa tela IPS Full HD

+ Chassi projetado para uso diário

+ Bons dispositivos de entrada

+ As durações da bateria são boas, mesmo com a pequena bateria

+ Bom desempenho

Contra

- A CPU chega a um máximo de 35 watts de TDP

- Desempenho não consistente no teste de estresse

- A ventoinha funciona de forma silenciosa e é muito barulhenta

- Ruído da bobina

In Review: Dell Precision 3520, courtesy of cyberport.de

O Precision 3520 definitivamente tem seus pontos positivos. Primeiro, está a tela, que é vívida e brilhante e agradável para trabalhar. A duração da bateria também é muito boa para um workstation e deve ser excelente com uma opção de bateria maior de 92 Wh. O número de portas físicas é suficiente. O chassi e os dispositivos de entrada são suficientemente bons para uma máquina empresarial, mas também não tão perfeitos.

Infelizmente, o Precision vacila quando se trata dos critérios mais importantes para estações de trabalho: desempenho e nível de ruído. A restrição para um TDP de 35 W pode já levantar algumas sobrancelhas - a Dell provavelmente teria que investir em um sistema de resfriamento mais sofisticado, o que, claro, não é tão realista, dado que este é um workstation econômico. Temos que perguntar se uma CPU nominalmente mais fraca não seria a melhor opção. Nosso teste de estresse revelou que o desempenho pode flutuar enormemente sob carga, provavelmente porque o firmware poderia ser melhorado. Infelizmente, isso também é verdade para o controle da ventoinha, porque a ventoinha gira frequentemente gira mesmo quando não há carga de trabalho. Após os benchmarks, demora um longo tempo para que a ventoinha pare de girar. Além disso, o 3520 sofre com o ruído de bobina.

O Precision 3520 é um workstation sólido - mas poderia ser ainda melhor.

Em resumo, podemos dizer que o Precision 3520 definitivamente tem potencial. O notebook é bastante poderoso e apresenta uma relação preço-desempenho comparativamente boa. Depois de tudo: os workstations podem ser bastante caros. No entanto, a Dell precisa voltar para a mesa do design e melhorar o controle da ventoinha e otimizar o desempenho. Assim que isso acontecer, o 3520 definitivamente será digno de uma recomendação.
