Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 3759 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 3759 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 3759 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
Então, o XPS 13 9370 com processador i7 é a melhor opção do que seu irmão mais barato com CPU i5? Neste momento, a resposta só pode ser um retumbante "não". Além da duração da bateria - que surpreendentemente supera a do modelo i5 UHD - o desempenho da nossa unidade de análise XPS 13 é um pouco decepcionante. Isso não quer dizer que o i7-8550U necessariamente se desempenhe muito pior nessa implementação em particular, do que em outros portáteis, mas o fato é que o XPS 13 9370 baseado em i7 não pode realmente se distanciar de nosso modelo de teste anterior com a CPU i5, que custa centenas a menos. É possível que tenhamos uma unidade defeituosa - as telas azuis e o colapso fatal do sistema certamente tornam isso uma explicação plausível. Caso tenhamos a chance de revisar um modelo de substituição posteriormente, atualizaremos esta análise adequadamente.
Dito isso, o XPS 13 9370 é certamente um companheiro agradável para o dia-a-dia com uma grande tela - apesar dos tempos de resposta lentos - e boa ergonomia por toda parte. Especialmente o controle do ventilador é executado com perfeição, já que as temperaturas da superfície sob uso normal e as cargas baixas a médias permanecem agradáveis e o ruído do sistema é muito mais constante e menos intrusivo do que o esperado de um aparelho fino e leve.
O XPS 13 9370 com i7-8550U é apenas uma opção atraente se um SSD maior e a quantidade máxima de RAM forem uma das principais preocupações. Um modelo i5 com 16 GB de RAM e SSD de 512 GB receberia nosso voto sempre, mas neste momento a Dell não oferece essa configuração específica.
