Parpadeo de Pantalla / PWM (Pulse-Width Modulation)
| Parpadeo de Pantalla / PWM detectado | 19690 Hz | ≤ 100 % de brillo |  |
La retroiluminación del display parpadea a 19690 Hz (seguramente usa PWM - Pulse-Width Modulation) a un brillo del 100 % e inferior. Sobre este nivel de brillo no debería darse parpadeo / PWM. La frecuencia de 19690 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 8706 (mínimo: 5 - máxmo: 343500) Hz. | |||

Contra
La intención principal de Dell con el Kaby Lake-R XPS 13 de octava generación era aumentar el rendimiento de la CPU a través de un mejor control de la temperatura. Por lo tanto, esta última iteración fue diseñada para funcionar a temperaturas de núcleo más altas que las SKU anteriores sin afectar negativamente la experiencia del usuario o elevar las temperaturas de la superficie a niveles incómodos. Nuestras pruebas reflejan más o menos estas afirmaciones, ya que las temperaturas centrales pueden sobrepasar los 90 ° C cuando están sometidas a una carga pesada sin afectar la necesidad de aumentar las velocidades máximas del ventilador. Las temperaturas de la superficie serán ligeramente más cálidas en ciertas partes del teclado, pero los reposamanos y el trackpad nunca se resultan incómodos.
Aparte del significativo salto en el rendimiento de la CPU y la menor mejora en el rendimiento de la GPU, no hay sorpresas para esta generación de XPS 13. Los mismos pros y contras de nuestras críticas anteriores. Hay un caso para el cual comprar la XPS 13 i7-7560U SKU en lugar de la SKU i7-8550U ya que los gráficos de Iris son un 18 por ciento más rápido que en la gráfica UHD 620, pero el rendimiento de la CPU es mucho más lento en un 40 por ciento. Las aplicaciones exigentes que se aprovechan del recuento de núcleos más alto amarán absolutamente a Kaby Lake-R y al nuevo XPS 13. Todavía hay margen de mejora ya que la velocidad de reloj constante de 2,5 GHz está muy lejos de los 3.7 GHz. Por lo tanto, será interesante ver cómo otros Ultrabooks que se divierten esta misma CPU se llevará a cabo en las próximas semanas.
El XPS 13 es una vez más un competidor muy fuerte en el espacio del subportátiles para esta temporada de vacaciones. El impulso de rendimiento es tal como se anunciaba a pesar de que esperábamos una mejor sostenibilidad de Turbo Boost durante periodos más largos.
