Contra
Você seria perdoado por pensar que pouco mudou com o novo portátil Precision 7700. A Dell tornou o Precision 7730 mais compacto do que seu antecessor, mas ainda é feito dos mesmos materiais.
O Precision 7730 ainda tem um bom teclado, além de uma carcaça robusta e diversas portas. Além disso, a Dell oferece mais opções de configuração do que seus concorrentes, o que torna o Precision 7730 uma opção mais flexível para as pessoas aos nossos olhos. Nossa unidade de análise também possui excelente desempenho de CPU e GPU, como é frequentemente em workstations, enquanto nós damos boas-vindas à inclusão de opções de telas mate. A Dell também equipou o Precision 7730 com um leitor de cartões SD impressionantemente rápido e inclui uma garantia de 36 meses como padrão, e gostamos dos dois.
O Dell Precision 7730 é um excelente workstation que é prejudicado pela sua decepcionante duração de bateria.
O maior problema com o Precision 7730 é a sua duração de bateria horrível. Enquanto a maioria das pessoas deixará o workstation em carga devido ao seu tamanho, o ThinkPad P72 continua a ser uma opção melhor para aqueles que ocasionalmente precisam usar seu dispositivo longe de uma tomada elétrica. Da mesma forma, nossa unidade de teste tem temperaturas de superfície inaceitavelmente altas, enquanto também afoga fortemente sua CPU e GPU com a bateria.
É uma pena ver um workstation afetado pelo bleeding da luz de fundo. Além disso, não podemos entender por que a Dell removeu o leitor de digitais incluído no Precision 7720.
No final, ainda recomendamos a compra do Precision 7730 se você estiver no mercado procurando um workstation. Deixando a duração da bateria de lado, o Precision 7730 oferece tudo o que você poderia querer de um workstation. Você sempre precisará ter seu carregador com você, se você planeja usar o dispositivo em movimento, mas provavelmente é muito volumoso para usar como um workstation móvel de qualquer maneira, e é por isso que ainda recomendamos considera-lo sobre outros workstations.
