Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 200 Hz | ≤ 30 % brightness setting |  |
The display backlight flickers at 200 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
Com o seu novo Blade Stealth, a Razer foi capaz de eliminar as desvantagens mais significantes: a medíocre duração da bateria. Com, entre 8 a 13 horas, o novo portátil pode ser utilizado longe das tomadas durante períodos muito mais longos e - dependendo das tarefas - durará o dia todo.
O chassi permanece igual. O design é definitivamente de gama alta e similar ao dos MacBooks da Apple, no que diz respeito à qualidade de construção e sensação táctil. É uma pena que a superfície preta mate seja tão suscetível às digitais, as quais são muito difíceis de remover.
Graças à CPU Kaby Lake e à bateria maior, o Blade Stealth agora consegue competir quando é comparado com outros subportáteis. A eGPU Razer Core é uma opção emocionante, mas mesmo sem ela, o Blade Stealth é um portátil bem-sucedido.
Desta vez o portátil que recebemos estava equipado com um painel QHD+. A tela ganha bons pontos e é quase tão boa quanto a opção 4K. Especialmente quando consideramos o pequeno tamanho de 12,5 polegadas, esta tela, em particular parece ser a melhor opção na maioria dos casos. A configuração com o painel de gama inferior também é 200 Euros (~$220) mais econômica e provavelmente contribui de forma positiva com o (menor) consumo de energia.
Também ficamos impressionados pelo desempenho oferecido. Os resultados do teste da CPU são bastante bons, inclusive quando o sistema está sujeito à carga contínua. O Blade Stealth deve trabalhar muito bem com o Razer Core e deve transformar a combinação em um genuíno sistema de jogos. Mais detalhes virão na seguinte análise
