A maioria dos OEMs normalmente reserva as GPUs GeForce 80 de gama alta para seus modelos carro-chefe entusiastas. Isto costumava ser a família Legion Y900 para a Lenovo, mas o fabricante desde então deixou essa série em espera deixando a série Legion Y700 de gama média como a oferte de maior gama. O resultado é um portátil de jogos de gama média com uma GPU GeForce de gama alta a preços muito mais acessíveis do que "super” portáteis de jogos concorrentes como o Alienware m17, Asus ROG G703, MSI GT75, ou Acer Triton 700. O portátil da Lenovo oferece o mesmo desempenho de jogo que essas alternativas de entusiastas por centenas de dólares a menos, em grande parte porque seu design de chassi é mais simples e menos excêntrico.
O desempenho da CPU é mais rápido do que a média do Core i7-8750H devido à excelente sustentabilidade do Turbo Boost. Tanto as temperaturas do núcleo como o ruído do ventilador são menores do que o esperado, considerando também o formato fino e o alto desempenho.
Como o Legion Y740 carrega um chassi de médio alcance, no entanto, as primeiras impressões não são tão fortes quanto as alternativas de gama alta já mencionadas. O dispositivo da Lenovo é mais propenso a se flexionar e balançar do que o mais rígido (e mais caro) MSI GT75 ou Asus ROG G703. Nossa unidade específica também sofre de bleeding da iluminação de fundo moderada-pesada e cores imprecisas. Suas teclas são mais suaves e geralmente mais fracas para jogos também. Os jogadores não perderão desempenho, mas o chassi e as teclas mais fracos afetarão a experiência geral de jogo.
O Legion Y740 de gama média é vendido por muito menos do que um portátil de jogos de 17,3 polegadas, entusiasta da concorrência, enquanto ostenta a mesma CPU e GPU de gama alta. Ele tem excelente valor em termos de desempenho, desde que você esteja conforme com seu design modesto e chassi mais flexível.
