Veredicto – O AMD ThinkPad oferece uma melhor relação preço-desempenho
Com o ThinkPad T495s, a Lenovo oferece outro portátil de escritório muito bom, depois do ThinkPad T495. Embora devido ao fracos sistema de resfriamento, você não possa aproveitar do desempenho pleno do Ryzen 7 Pro processador, o mesmo acontece com a carcaça para o T490s também com o processador Intel. Ambos os sistemas oferecem desempenho suficiente para a maioria das tarefas no escritório. A duração da bateria também é particularmente encorajadora, pois não há mais desvantagens para o ThinkPad AMD aqui. A carcaça e o teclado são idênticos nos dois modelos de qualquer maneira.
No entanto, há uma grande desvantagem, pois o ventilador produz um ruído de frequência muito alta que é muito irritante em comparação com o ventilador do T490s. Embora o ventilador esteja geralmente desativado durante tarefas menos exigentes, a Lenovo poderia ter evitado esse problema facilmente. Por outro lado, a falta de uma conexão Thunderbolt-3 não deve representar um problema para muitos usuários.
Com o ThinkPad T495s, a Lenovo oferece uma alternativa muito boa e, acima de tudo, mais acessível ao ThinkPad T490s baseado em Intel. Se não fosse pelo problema com o ruído agudo do ventilador, o T495s receberia nossa recomendação incondicional.
No entanto, também está o preço e, nesse sentido, o AMD ThinkPad está claramente à frente. Você pode esperar uma vantagem de preço de pelo menos 300 Euros (~US$ 330), e o modelo Campus que temos aqui é um campeão em preços-desempenho por 1.299 Euros (~US$ 1.429) de qualquer maneira.
Nota: Devido à atualização v7 do nosso sistema de classificação, a classificação do ThinkPad T490s foi reduzida de 92% para 89%. O fato do ThinkPad T495s fica atrás disso em 88% deve-se principalmente ao ventilador de alta frequência.
