The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 38 % of all devices are better. This means that the measured response time is better than the average of all tested devices (20.9 ms). | ||

The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 37 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.8 ms). |
Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 208.3 Hz | ≤ 50 % brightness setting | |
The display backlight flickers at 208.3 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 208.3 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. |

Contra
Você realmente precisa de um iMac Pro ou é suficiente um iMac regular? Bem, se você tem essa pergunta, você provavelmente não precisa da versão Pro, porque os componentes profissionais são para um grupo de usuários especial. Os núcleos adicionais dos processadores Xeon devem ser utilizados, caso contrário não é mais rápido. Ocorre o mesmo com as placas gráficas. Se for esse o caso, você pode optar pelo iMac 5K regular, que é muito mais acessível e oferece a mesma tela.
Mas o iMac Pro não é um workstation realmente convincente. Sim, o desempenho é muito bom, mas a solução de resfriamento já tem problemas com os componentes de nível de entrada sob carga máxima. A tela poderia ser melhor calibrada na fábrica e você precisará de uma tela externa para trabalhos gráficos no espaço de cores AdobeRGB. Outras desvantagens para um sistema profissional incluem as opções de serviço limitado, complicado e limitado. Se você confiar em um sistema para o trabalho, provavelmente comprará serviços adicionais, como reparos no local. Outros fabricantes como a Dell, HP e Lenovo claramente têm uma vantagem a esse respeito.
O preço de nível de entrada é alto, mas certamente não é completamente caro considerando os componentes. O processador Intel Xeon, por si só, custa mais de $1.100, mas não conseguimos entender os preços massivos de RAM e armazenamento adicionais. O iMac Pro definitivamente tem um certo apelo e se desempenha bem, mas não é a escolha certa para todos os usuários profissionais.
