Breve análisis del portátil convertible Lenovo IdeaPad Miix 720 (7500U, QHD)

Surface con pantalla en formato 3:2. Con su pantalla QHD+ y SoC Kaby Lake de 15 watt, el IdeaPad Miix 720 compite cara a cara con el Microsoft Surface. Pero los ventiladores y los micrófonos de mala calidad arruinan un poco la experiencia con este dispositivo de 12 pulgadas.

Tiempos de respuesta del display

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.
       Tiempo de respuesta de Negro a Blanco
24 ms ... subida ↗ y bajada ↘ combinada↗ 14 ms subida
↘ 10 ms bajada
La pantalla mostró buenos tiempos de respuesta en nuestros tests pero podría ser demasiado lenta para los jugones competitivos.
En comparación, todos los dispositivos de prueba van de ##min### (mínimo) a 240 (máximo) ms. » 48 % de todos los dispositivos son mejores.
Eso quiere decir que el tiempo de respuesta es peor que la media (21.6 ms) de todos los dispositivos testados.
       Tiempo de respuesta 50% Gris a 80% Gris
45 ms ... subida ↗ y bajada ↘ combinada↗ 22 ms subida
↘ 23 ms bajada
La pantalla mostró tiempos de respuesta lentos en nuestros tests y podría ser demasiado lenta para los jugones.
En comparación, todos los dispositivos de prueba van de ##min### (mínimo) a 636 (máximo) ms. » 73 % de todos los dispositivos son mejores.
Eso quiere decir que el tiempo de respuesta es peor que la media (33.9 ms) de todos los dispositivos testados.

Parpadeo de Pantalla / PWM (Pulse-Width Modulation)

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 no detectado

Comparación: 53 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 18110 (mínimo: 5 - máxmo: 3846000) Hz.

Análisis: Lenovo IdeaPad Miix 720-12IKB. Modelo de prueba cedido por Notebooksbilliger

Con el IdeaPad Miix 720 Lenovo lanza una respuesta al Surface Pro 4, la similitud de las pantallas con el mismo ratio 3:2 y la alta resolución (2736x1.824 en el surface, 2880x1920 en el Miix 720) hace que sean casi intercambiables. Respecto a la pantalla no hay nada que criticar excepto, quizás, que la cobertura del espacio de color es mejorable.

La ventaja del Miix es que está equipado con más puertos: 2x  USB 3.0 Type-A, USB Type-C Gen2 con Thunderbolt 3 y una cámara IR para usar Windows Hello. En el aspecto técnico, se incluye un procesador Kaby Lake además de un RAID-SSD muy rápido.

Desafortunadamente, el mix 720 no puede utilizar toda la potencia del SoC, se pierde un 10% de rendimiento durante el funcionamiento continuo de aplicaciones cotidianas. Esto lo pone al mismo nivel que el el Surface Pro 4 i7. Incluso modelos más asequibles como el Aspire Switch Alpha 12 (i5) llevan su SoC Skylake SoCs a rendimientos iguales o superiores.

El Switch Alpha 12 con i5 está disponible desde 750 Euros, el Microsoft Surface Pro 4 + Type Cover (i5-6300U) por 1200 Euros. La pregunta entonces es: ¿Por que comprar el Miix 720 cuando el rendimiento del procesador está por debajo de lo deseado?

El Miix 720 no resulta barato: La versión con 7500U, 16 GB SSD de 1 TB cuesta 1700 Euros. Para la mayor parte de los usuarios, sin embargo, la versión con 256 o 128 GB y Core i3 o i5 7200U debería ser suficiente. Están disponibles por 1070 Euros.

La variante más pequeña es suficiente para disfrutar de las ventajas del Thunderbolt 3 al funcionar conectado a la base, la duración de batería, la gran pantalla, la cámara IR compatible con Windows Hello y el versátil teclado retroiluminado. En algún momento el precio bajará, un precio de unos 900 euros por la versión i3 sería un precio competitivo.
