Contra
A Acer criou um portátil multimídia fora do comum com o ConceptD 5 CN515-51.
Ele se vê diferente de outros modelos desta classe e tem um foco forte no peso baixo graças aos materiais do chassi. Isso é algo bom, mas a tampa fraca da tela parece ser um efeito secundário negativa deste foco sob uma iluminação baixa. No que se refere às portas, a Acer não incluiu Thunderbolt 3. Também é utilizado um leitor de cartões SD extremamente lento, que está completamente mal posicionado em um portátil multimídia caro. O mesmo é verdade para o módulo Wi-Fi desatualizado, que nem sequer suporta o mais recente padrão Bluetooth. Louvável e censurável é a capacidade de atualização: Enquanto a RAM é completamente soldada, a capacidade de armazenamento em massa pode ser atualizada facilmente, graças ao slot M.2 2280 disponível.
A tela do portátil Acer possui uma excelente cobertura de cores, seu brilho mais baixo do que o prometido e o bleeding da luz de fundo relativamente forte, nos decepcionam. Em termos de desempenho, o ConceptD oferece aproximadamente o que esperávamos do Kaby Lake G. Um bom desempenho para um portátil multimídia, mas muitos outros portáteis com CPUs Intel mais recentes e GPUs Nvidia dedicadas oferecem melhor desempenho. Infelizmente, isto não resulta em uma melhor duração da bateria, em troca. Em vez disso, a bateria arruina a equação, pois é muito pequena. Além disso, temos que pesar negativamente o ruído da bobina, a limitação de desempenho quando o dispositivo funciona com energia da bateria e os falantes abaixo da média (para um portátil multimídia).
Não sem compromissos: Infelizmente, a Acer decidiu cortar custos em componentes cruciais. Não pode competir com os concorrentes mais caros.
Para nós, não está claro para quem a Acer deseja comercializar o ConceptD 5 CN515-51. A característica positiva mais destacada é o baixo peso e a tela colorida. Com esses dois pontos fortes, parece destinado a ser um sonho dos fotógrafos. Este grupo, no entanto, provavelmente ficará extremamente irritado com o lento leitor de cartões SD Além disso, a baixa duração da bateria é um problema. O ConceptD pode ser usado para jogar, mas também não foi feito para isso.
