Embora não muito tenha mudado em termos de design básico, desde o Precision 5510 há cerca de uma ano atrás, o Dell Precision 5520 ainda é um dos workstations mais portáveis e atraentes que existe. O movimento para Kaby Lake vê resultados mistos, com limitações de desempenho da CPU sob carga contínua, impedindo que a máquina atinja seu potencial pleno em desempenho multi-core, mesmo sob condições de teste de estresse realistas. Mas a atualização para o armazenamento NVMe e a adoção da mais recente NVIDIA Quadro M1200 traz benefícios tangíveis para o desempenho do workstation do aparelho: registramos resultados respeitáveis em todos os nossos testes SPECviewperf e, em geral, bem acima dos do 5510, para inicializar.. O desempenho da GPU também parece ser bastante estável sob o nosso teste de estresse Witcher 3.
Alguns sacrifícios são esperados quando se lida com um workstation deste tamanho; afinal, o 5520 pesa pouco mais de 2 kg e tem um formato mais próximo do de uma máquina de 14 polegadas. Além das restrições da CPU, o Precision também esquenta bastante sob carga, e a duração da bateria não é absolutamente nada especial (pelo menos, com a tela UHD que recebemos em nossa unidade de teste). Assim, enquanto o sonho de um Ultrabook/workstation híbrido ainda não é realizado, para aqueles que ficarem contentes com um bom desempenho de GPU/workstation, e não se importam com decepcionantes capacidades da CPU multi-core, o Precision 5520 é um compromisso atraente em troca de maior portabilidade e estética mais agradável.
Para outros, um workstation maior provavelmente seja a única resposta — no entanto, sempre há outras opções ultra portáveis (grau de consumidor) como o XPS 15 e o Razer Blade se esses conseguirem qualificar. Por exemplo, embora a nossa unidade de teste XPS 15 não teve o mesmo poder de CPU que o nosso Precision, as velocidades e o desempenho foram estáveis no teste Cinebench loop — e, no geral, um desempenho contínuo é melhor.
Alguns sacrifícios são esperados quando se lida com um workstation deste tamanho; para aqueles cujas necessidades ele atende, o Precision 5520 é um compromisso atraente em troca de maior portabilidade e estética mais agradável.
Não há mais espaço para melhorias com a próxima revisão, mas para o que é, o Precision 5520 ainda é um dispositivo impressionante com um sólido desempenho de GPU profissional para o seu tamanho. A $ 2.867 (como configurado), não é um investimento pequeno, mas é também (ainda hoje) único em sua classe.
