| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 66 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||

| 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. » 46 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 19690 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 19690 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 19690 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
A principal intenção da Dell com o XPS 13 Kaby Lake-R de 8va geração foi impulsionar o desempenho da CPU através de um melhor monitoramento de temperatura. Assim, esta última iteração foi projetada para funcionar em temperaturas de núcleo mais altas do que as SKUs anteriores, sem impactar negativamente a experiência do usuário ou aumentar a temperatura da superfície em níveis desconfortáveis. Nossos testes mais ou menos ecoam essas afirmações, pois as temperaturas podem passar mais de 90 C quando está sob carga pesada sem afetar a necessidade de aumentar as velocidades máximas da ventoinha As temperaturas da superfície serão ligeiramente mais quentes em certas partes do teclado, mas o pousa palmas e o trackpad nunca ficam desconfortáveis.
Além do salto significativo no desempenho da CPU e uma leve melhoria no desempenho da GPU, não há surpresas para esta geração XPS 13. Os mesmos prós e contras das nossas análises anteriores permanecem. Há um caso para comprar o XPS 13 i7-7560U SKU em vez do i7-8550U SKU dado que os gráficos Iris se desempenham 18% mais rápido que o UHD Graphics 620, mas o desempenho da CPU é muito mais lento em cerca de 40%. Aplicativos exigentes que aproveitam a maior contagem do núcleos adorarão a Kaby Lake-R e o novo XPS 13. Ainda há espaço para melhorias, uma vez que a velocidade constante de 2,5 GHz está muito longe dos 3,7 GHz. Assim, será interessante ver como outros Ultrabooks ostentando essa mesma CPU funcionarão nas próximas semanas.
O XPS 13 é mais uma vez um concorrente muito forte no espaço dos subportáteis para esta temporada de férias. O impulso de desempenho é como anunciado, embora tenhamos esperado uma melhor sustentabilidade do Turbo Boost por longos períodos.
