In review: Lenovo ThinkPad T480s. Test model courtesy of Campuspoint.

Nossa impressão inicial do novo ThinkPad T480s é muito positiva. A Lenovo agora usa o painel WQHD aparentemente mais eficiente do X1 Carbon e conseguiu melhorar bastante o tempo de duração da bateria.

A utilização do desempenho é uma história interessante agora. O Core i5-8250U oferece excelentes figuras de desempenho sem a limitação de TDP e a solução de resfriamento não está sobrecarregada. As temperaturas da superfície resultantes são certamente muito quentes, mas ainda mais baixas do que no X1 Carbon 2018, por exemplo. O ruído dos ventiladores também está bem. Nós suspeitamos que esta exata unidade de resfriamento também será usada para SKUs com a discreta GPU MX 150 da Nvidia. Nós também testaremos esse modelo em breve.

A análise completa do novo ThinkPad T480s estará disponível na próxima semana.
