Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 25000 Hz | ≤ 40 % brightness setting |  |
The display backlight flickers at 25000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 25000 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 8706 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
O Lenovo ThinkPad E495 é um portátil de escritório sólido por pouco dinheiro. Por menos de 700 Euros (~US$ 770), você recebe uma carcaça estável, ótimos dispositivos de entrada, muita energia e uma bateria decente. A comparação com o modelo Intel também mostra que a Lenovo limita um pouco artificialmente o E495. O plástico na superfície da unidade base parece muito mais barato com seu revestimento áspero e não entendemos por que não há iluminação no teclado ou um leitor de digitais nem mesmo a um custo extra.
O desempenho do SoC Ryzen é muito bom e a CPU e a GPU obtêm uma pontuação melhor que a do Intel Core i5. No entanto, a Radeon RX 550X (opcional) dedicada no ThinkPad E490 oferece visivelmente mais potência gráfica e, portanto, é recomendada se você também quiser usar o ThinkPad para jogos. Nem o E490 nem o E495 oferecem Thunderbolt 3, portanto, a conexão de uma eGPU não é possível. Para explorar todo o potencial do SoC AMD, você também precisa de outro módulo de RAM.
Bom valor pelo dinheiro: O ThinkPad E495 oferece mais energia do que o modelo Intel um pouco mais caro e não possui mais desvantagens em termos de duração da bateria. No entanto, deve-se aceitar a falta de recursos (especialmente a iluminação do teclado) e o plástico mais barato.
Atenção: Desde a análise do ThinkPad E490, atualizamos nosso sistema de pontuação para a versão 7 (veja Aqui). Isso reduz a classificação do E490 de 89% para 86%. O ThinkPad E485 atinge 84%. A discrepância, conforme listamos neste artigo, resulta das diferenças no equipamento e do material da carcaça.
