Display Response Times
ℹ
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 | ||
|---|---|---|
| 25.6 ms ... rise ↗ and fall ↘ combined | ↗ 15.6 ms rise |  |
| ↘ 10 ms fall | ||
| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 58 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 34.4 ms ... rise ↗ and fall ↘ combined | ↗ 18.8 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 0.165 (minimum) to 636 (maximum) ms. » 44 % 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)
ℹ
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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8706 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Quanto mais rápido é o SKU Yoga C930 Core i7 em comparação com o SKU Core i5? Espere um aumento de 20% na potência bruta da CPU, quando ambos os sistemas estiverem sob forte estresse. O SKU Core i7 é melhor para manter as velocidades Turbo Boost mais rápidas por mais tempo, sem necessariamente afetar a duração da bateria para tarefas do dia-a-dia, como navegação, streaming ou processamento de texto. Os usuários que sabem que podem aproveitar a potência adicional serão os que mais se beneficiarão da configuração mais cara.
Para todos os demais, o delta de desempenho entre os SKUs Core i5 e Core i7 é imperceptível. O Core i5-8250U é mais que suficiente para navegação, streaming e cargas multitarefa. Em vez disso, o aspecto mais fraco do Yoga C930 são seus gráficos, já que a série continua sem opções dedicadas da Nvidia ou até da Iris. É mais provável que os proprietários percebam o desempenho gráfico limitado do portátil na edição de imagem ou vídeo, em comparação com as diferenças comparativamente mínimas entre o Core i5 e o Core i7.
O Yoga C930 está cada vez mais perto de ser um conversível híbrido de consumo-empresarial com seu design portátil e caneta ativa indiscutivelmente útil. As tarefas básicas de escritório ou de entretenimento doméstico serão executadas tão bem quanto no SKU Core i5 quando comparado ao Core i7. Os usuários que desejam mais potência gráfica, no entanto, devem considerar o MateBook X Pro, MSI PS42, ou o XPS 13 com gráficos Iris.
