Breve Análise do Portátil Dell XPS 15 9575 (i7-8705G, Vega M GL, 4K UHD)

Allen Ngo (traduzido por Ricardo Soto), 05/11/2018

Preço mais alto, mesmo desempenho da CPU. O Core i5 XPS 15 9575 nos impressionou em termos de desempenho bruto e poder gráfico para um conversível tão fino. O SKU Core i7 se desempenho igual de bem, no entanto, com benefícios muito marginais. Para melhor ou pior, as diferenças entre os SKUs i5 e i7 são menores do que prevíamos.

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
34.8 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 15.6 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. » 89 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.1 ms).
       Response Time 50% Grey to 80% Grey
48.4 ms ... rise ↗ and fall ↘ combined↗ 23.2 ms rise
↘ 25.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.7 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 detected 1000 Hz ≤ 25 % brightness setting

The display backlight flickers at 1000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 25 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10402 (minimum: 43 - maximum: 588200) Hz was measured.

Os SKUs atuais do XPS 15 9560 incluem o Core i5-7300HQ e o Core i7-7700HQ similar a como a atual seleção dos SKUs XPS 15 9575 incluem o Core i5-8305GCore i7-8705G. Considerando que o salto de um i5-7300HQ para i7-7700HQ pode trazer um aumento de 40 por cento no desempenho, o salto de um i5-8305G para i7-8705G é apenas de 5 a 10 por cento. Quando você considera a enorme diferença de custo entre os SKUs i5 e i7 do XPS 15 9575 ($1300 USD vs. $2200 USD), fica claro que os usuários não devem comprar a configuração do Core i7 se o desempenho por dólar for prioridade.

Em vez disso, a Dell está justificando o grande preço delta com a maior RAM e o painel de resolução mais alta que só vem com o Core i7 SKU. Multi-taskers pesados, usuários de stylus de tela táctil e editores de vídeo encontrarão mais valor na opção de 16 GB de RAM e 4K UHD do que a maioria dos usuários domésticos. No entanto, é um pouco decepcionante que os atuais SKUs do Core i5 estejam limitados a apenas 8 GB de RAM.

Além das diferenças acima, nossos comentários existentes sobre o Core i5 XPS 15 9575 ainda se aplicam aqui. O Kaby Lake-G está provando ser uma excelente alternativa para o onipresente Core i7-7700HQ e GTX 1050 ou 1050 Ti comumente encontrados em portáteis concorrentes. O conversível da Dell é ainda mais eficiente em termos de energia e mais frio do que os sistemas mencionados e mais silencioso que o XPS 15 9560. Desde que os usuários estejam cientes de sua lista de inconvenientes (veja à direita), os conversíveis de 15 polegadas concorrentes não chegam perto do que o XPS 15 9575 pode oferecer, com a notável exceção do próximo HP Spectre x360 15 2018.

Você não precisa gastar $2200 USD na opção Core i7-8705G quando o Core i5-8705G estiver apenas um pouco mais lento por quase $1000 USD a menos. Mesmo a configuração mais barata do XPS 15 9575 é quase tão rápida quanto o XPS 15 9575 ou XPS 9560 mais caros. Esperamos ver mais RAM e opções de telas para os futuros SKUs Core i5 para tornar a série ainda mais atraente.
