Breve Análise do Conversível Dell Inspiron 7390 2-em-1 Black Edition

Steve Schardein, 👁 Allen Ngo (traduzido por Ricardo Soto), 08/29/2019

Toma dois. O Inspiron 2-em-1 7390 pode parecer muito semelhante ao seu antecessor, mas sob o capô, muita coisa mudou. Por US$ 1.250, o conversível inclui uma tela UHD, Core i7-8565U, 16 GB de RAM e um SSD NVMe de 512 GB. Será que este é o seguinte conversível a derrotar?

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
37.6 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms rise
↘ 17.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 94 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25 ms).
       Response Time 50% Grey to 80% Grey
56.4 ms ... rise ↗ and fall ↘ combined↗ 27.6 ms rise
↘ 28.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 92 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9418 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Dell Inspiron 7390 2-in-1 Black Edition

O Dell Inspiron 7390 2-em-1 Black Edition de US$ 1.249 (conforme configurado) pode não parecer muito diferente de seu antecessor, mas na verdade resolve algumas das maiores reclamações que tivemos sobre o Inspiron 7386 2-em-1. A principal delas é o consumo de energia no modo ocioso, que caiu quase para a metade, e a duração da bateria, que é 40% mais longa do que antes. Também não detectamos nenhum ruído da bobina em nossa unidade de teste, e a tela é um pouco mais brilhante do que antes. Até o desempenho da CPU também está um pouco melhor do que era anteriormente, apesar do fato de as duas máquinas serem impulsionadas pelo mesmo chip.

Além disso, a tela UHD é atraente, com boa reprodução e calibração de cores prontas para uso, e o botão liga/desliga redesenhado (com leitor de digitais integrado) e o layout do teclado funcionam bem em nossa opinião. O design da construção e da carcaça é bom para sua classe e parece um pouco mais resistente do que alguns dos concorrentes de metal mais finos. Por fim, o novo design inteligente da dobradiça da Dell, que incorpora uma cavidade magnética para a Dell Active Pen incluída, é uma das melhores soluções de armazenamento que vimos para uma caneta de tamanho normal.

O Inspiron 7390 2-em-1 aprimora seu antecessor de várias maneiras - mais notavelmente, duração da bateria muito melhor e desempenho ainda melhor. Apesar de algumas reclamações sobre os dispositivos de entrada e o valor questionável da CPU Core i7, ele representa uma alternativa séria aos concorrentes de fabricantes como Lenovo e HP.

Ainda assim, algumas das mesmas queixas permanecem. O desempenho ainda é insatisfatório no contexto, com os resultados publicados pelos concorrentes do cTDP Up, como Lenovo’s ThinkBook 13s, que são realmente melhores. A seleção de portas é escassa e a falta de Thunderbolt 3 e uma porta Kensington Lock incomodará alguns usuários. O teclado é razoavelmente bom, mas a resposta e a força de atuação poderiam ser melhores. Da mesma forma, os botões do touchpad integrado exigem muita força para serem accionados e se tornam bastante cansativos para operar depois de um tempo. Por fim, embora a tela seja certamente agradável, teria sido bom ter uma opção de FHD, o que aumentaria bastante a duração da bateria.

Alguns concorrentes diretos que vale a pena considerar incluem o ThinkPad X1 YogaBreve Análise do Conversível HP Envy x360 13:Uma alternativa ThinkPad X390 Yoga, e—no lado mais caro—o Latitude 7400 2-in-1. Além das preocupações sobre os dispositivos de entrada e as lamentações que cercam os chips de preço mais alto, o peso do Inspiron 7390 2-em-1 agora parece uma alternativa razoável aos populares conversíveis da série Yoga e x360 que se elevavam acima do seu antecessor.
