Como antes, o venerável ThinkPad T480 da Lenovo continua sendo um dos principais concorrentes no mercado corporativo. É um produto de anos de refinamento e revisão cuidadosa, rivalizado apenas por um punhado de máquinas verdadeiramente de alto nível. Como dissemos durante a nossa última análise, a sua construção é na maior parte muito sólida, o design é sempre prático (e imediatamente familiarizar), e há uma boa seleção de portas abordo. Os dispositivos de entrada também são muito bons, a máquina é silenciosa durante a operação e também é rápida - pelo menos, para o desempenho de aplicativos em geral, e no contexto das médias da categoria para o desempenho da CPU.
O que melhorou com o modelo atual em comparação com o anterior, começa com o preço, que atualmente está em torno de $1.712,00 (na Amazon). Além disso, dado que esta configuração não apresenta gráficos dedicados, as temperaturas e o consumo de energia também estão bem abaixo dos valores que medimos do modelo anterior - embora ainda haja alguns pontos quentes no lado inferior, sob carga. A tela permanece brilhante e apresenta um bom contraste, mas, como antes, a cobertura de cores é totalmente inadequada, o que resulta em cores desbotadas e a uma qualidade de imagem absurda.
Apesar de falhar no domínio da qualidade das cores da tela e de algumas outras categorias esparsas, o venerável ThinkPad T480 da Lenovo continua sendo um dos principais concorrentes no mercado corporativo. É um produto de anos de refinamento e revisão cuidadosa, rivalizado apenas por um punhado de máquinas verdadeiramente de alto nível.
Ao contrário da configuração MX150, esta máquina (é claro) não consegue lidar com nenhum tipo de operação pesada de GPU, como jogos leves. Isso é esperado - mas o que foi inesperado é o menor desempenho da CPU que recebemos do Core i7 2670QM em nossa unidade de teste, contra o modelo Core i7 2670QM mais barato, em março. Talvez o mais enigmático de tudo seja a brecha de desempenho da CPU que separa o T480s e o T480 atual; mesmo com o BIOS mais recente e todas as configurações de energia configuradas corretamente, não conseguimos provocar pontuações próximas do que vimos nos nossos T480 equipados com Core i5 na semana passada.
Ainda assim, apesar de falhar no campo da qualidade das cores da tela e de algumas outras categorias esparsas, o T480 continua sendo mencionado entre as respeitadas categorias de concorrentes como a Dell.Dell Latitude 7490, HP Elitebook 840 G5, e o X1 Carbon da própria Lenovo. A escolha real é se o T480 ou o T480s faz mais sentido para a sua aplicação em particular, mas, além dos problemas mencionados, é difícil encontrar uma falha grave em qualquer uma dessas opções.
