Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 21550 Hz | ≤ 91 % brightness setting |  |
The display backlight flickers at 21550 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 91 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 21550 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. | |||

Pro
Contra
Até agora, a ideia de um portátil workstation com processadores energeticamente eficientes nunca funcionou. O Lenovo ThinkPad P52s é o primeiro portátil onde este conceito está, finalmente, começando a decolar.
Isso se deve principalmente ao fato de que os processadores Ultra-Low-Voltage da geração Kaby Lake Refresh deram um grande salto quando se trata de desempenho. Embora o desempenho da CPU ainda esteja longe de competir com o dos CPUs de 45-Watt Coffee Lake, ele ainda cumpre os requisitos mínimos para um workstation móvel. Além disso, o desempenho do processador está acima da média no P52s e significativamente melhor que no ZBook 15u G5, que está equipado com o mesmo processador. O P52s também carregou uma série de características positivas do ThinkPad T580, como a carcaça robusta com boas opções de manutenção, os populares dispositivos de entrada ThinkPad, a grande seleção de portas e recursos de segurança e a longa garantia padrão. À diferença do T580, nossa unidade de teste tem bons tempos de duração de bateria e o PowerBridge, que oferece grandes vantagens.
Ironicamente, o Quadro P5000, a única diferença real entre o P52s e o ThinkPad T580, também é a maior fraqueza do dispositivo. O desempenho da GPU Quadro não pode acompanhar o desempenho da GeForce MX150 no T580, devido à quantidade limitada de shaders. Naturalmente, existem também algumas desvantagens do T580 que foram transportadas para o P52, tais como os longos tempos de carga e o forte aquecimento sob uso intenso. A tela do nosso P52s oferece apenas uma resolução Full HD. Algumas das medições estão significativamente acima das especificações da Lenovo - por exemplo, a alta taxa de contraste. No entanto, a cobertura de espaço de cores é tão ruim quanto sempre, o que é uma marca bastante negra para um workstation móvel.
Basicamente, podemos recomendar o Lenovo ThinkPad P52s, mas será realmente interessante para um pequeno grupo de potenciais compradores, pois o Quadro P500 é simplesmente muito fraco.
Podemos dar uma recomendação de compra para o ThinkPad P52s? Basicamene, sim. Ele derrota seu concorrente direto, o HP ZBook 15u em muitas áreas - apenas o gerenciamento de temperatura e a sensação da carcaça são melhores no ZBook. Mas ainda assim, o P52s só será realmente adequado para um pequeno grupo de usuários, dado que o ThinkPad T580 oferece todas as qualidades do P52s e tem uma GPU mais potente. Somente usuários de software CAD podem preferir o P52s - mas novamente a questão é se esses usuários podem preferir comprar um workstation mais grosso e pesado com uma CPU e GPU mais fortes. Isso limita o mercado-alvo a alguns usuários que precisam de longos tempos de duração de bateria e uma GPU otimizada para CAD.
