Parpadeo de Pantalla / PWM (Pulse-Width Modulation)

ℹ

Para atenuar el brillo de pantalla algunos portátiles están encendiendo y apagando la retroiluminación muy rápidamente. Esto se hace a una frecuencia que no debiera detectarse a simple vista. Si la frecuencia es demasiado lenta, la gente sensible podría experimentar problemas visuales, dolores de cabeza e incluso ver parpadeos.

Parpadeo de Pantalla / PWM detectado

1064 Hz

≤ 90 % de brillo

La retroiluminación del display parpadea a 1064 Hz (seguramente usa PWM - Pulse-Width Modulation) a un brillo del 90 % e inferior. Sobre este nivel de brillo no debería darse parpadeo / PWM.

La frecuencia de 1064 Hz es bastante alta, por lo que la mayoría de gente sensible al parpadeo no debería ver parpadeo o tener fatiga visual.

Comparación: 53 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 8746 (mínimo: 5 - máxmo: 343500) Hz.

Tiempos de respuesta del display

ℹ

Los tiempos de respuesta del display muestran lo rápido que puede cambiar la pantalla de un color al siguiente. Tiempos lentos de respuesta pueden llevar a imágenes persistentes alrededor de objetos en movimiento o a displays borrosos. Particularmente los aficionados a los juegos 3D frenéticos deberían usar una pantalla con tiempos de respuesta rápidos.

Pro

+ Buena cantidad de puertos

+ Muy buena pantalla Full HD IPS

+ Chasis diseñado para su uso cotidiano

+ Buenos dispositivos de entrada

+ La duración de la batería es decente a pesar de su pequeño tamaño

+ Buen rendimiento

Contra

- La CPU tiene un consumo máximo de 35 watts de TDP

- El rendimiento en los test de estrés no fue consistente

- El ventilador funciona a menudo y es muy ruidoso

- Ruido electrónico

Análisis: Dell Precision 3520, modelo de prueba cedido por cyberport.de

El Precision 3520 definitivamente tiene puntos positivos. En primer lugar la pantalla, que muestra colores vivos y es brillante. La duración de batería es muy buena para una estación de trabajo y debe ser impresionante con la opción de 92 Wh. El número de puertos es suficiente. El chasis y los dispositivos de entrada son suficientemente buenos para una máquina de negocios, pero no perfectos.

Desafortunadamente el Precision falla respecto a lo más importante para una estación de trabajo: rendimiento y nivel de ruido. La restricción a un TDP de 35 W resulta sorprendente - Dell probablemente debería buscar un sistema de refrigeración más sofisticado, aunque no podemos olvidar que estamos ante una estación de trabajo de bajo precio. Nos preguntamos si no habría sido mejor elección una CPU con un consumo más bajo. Nuestro test de estrés revela que el rendimiento puede variar mucho bajo carga, como si el firmware realizase algún tipo de ajustes. Desafortunadamente, esto ocurre también con el control de ventilador, ya que en ocasiones se activa sin motivo aparente. Tras las pruebas, el ventilador tardó mucho en desactivarse de nuevo. Además el 3520 emite un ruido electrónico.

The Precision 3520 es una estación de trabajo solida - pero podría mejorar en varios aspectos.

En resumen podemos decir que el Precision 3520 tiene potencial. El portátil es muy potente y tiene un buen ratio precio-rendimiento. Al fin y al cabo las estaciones de trabajo pueden ser muy caras. De todas formas Dell necesita replantearse el control del ventilador y mejorar el rendimiento. En cuanto eso ocurra, el 3520 será una buena recomendación de compra.
