Pro
Contra
Embora ainda tenha sua parcela de inadequações, o Y740-15ICHg elimina cerca de metade das queixas originais que apresentamos sobre seu predecessor direto, o Y730-15ICH. O novo painel da tela melhora consideravelmente os tempos de resposta em preto e branco e apresenta uma taxa de atualização de 144 Hz (para o NVIDIA G-Sync). Além disso, a limitação da GPU foi levantada; o RTX 2070 Max-Q é mais de duas vezes mais veloz que o anterior GeForce GTX 1050 Ti. Tudo isto é conseguido sem um aumento substancial no ruído do ventilador do sistema, embora as temperaturas da superfície tenham certamente aumentado notavelmente.
Outras vitórias notáveis para o Legion Y740-15ICHg incluem desempenho de CPU muito potente, tanto de curto prazo quanto sustentado, bem como desempenho geral rápido do sistema graças à combinação com um SSD NVMe Samsung PM981. A máquina se esforça para lidar com o estresse do sistema sintético combinado, mas o estresse da CPU e da GPU, de forma independente, não apresenta problemas, e os jogar jogos normais do mundo real, é tranquilo. É verdade que é improvável que os jogadores alcancem taxas de quadros estáveis de 144 fps+ sem reduzir a qualidade para configurações médias ou baixas na maioria dos jogos, mas ainda é bom ter essa opção.
Embora fique aquém das áreas de portabilidade e dispositivos de entrada, o Lenovo Legion Y740-15ICHg é uma melhoria significativa em relação ao seu antecessor, lidando facilmente com a maioria dos jogos com calma e sem criar um buraco na carteira.
O design, embora não convencional, tem sucesso estético e ao mesmo tempo, embora, do ponto de vista da durabilidade, deixa algo a desejar. A tampa da tela, em particular, é mais flexível do que gostaríamos e o dispositivo se flexiona sob uma pressão moderada no centro da unidade base. Os dispositivos de entrada são meramente decentes; o deslocamento curto das teclas e a resposta esponjosa do teclado e a força de atuação cansativa dos botões do touchpad são facilmente superados pelos principais concorrentes (como o XPS 15 e MSI GS60). A manutenção é relativamente simples.
O Legion Y740-15ICH tem um bom preço, com um preço recomendado pelo fabricante de $1990 para nossa configuração (com um desconto que baixa até aproximadamente $1.752 até o momento da redação deste texto). Ele é poderoso o suficiente para rodar praticamente todos os jogos modernos em configurações altas, resolução nativa FHD com mais de 60 fps. A concorrência inclui o Alienware m15, Razer Blade 15, Acer Predator Triton 500, e MSI GE75, todos os quais carregam seus próprios prós e contras. Tudo somado, no entanto, o Y740 representa uma melhoria substancial em relação ao seu antecessor, e uma consideração séria para aqueles que procuram um portátil de jogos capaz que lida com os principais desafios sem criar um buraco em sua carteira.
