Test: Lenovo Ideapad 720S-13IKB (i5-8250U, UHD 620) Laptop (Sammanfattning)

Mike Wobker (översatt av Daniel Eriksson), 02/09/2018

Ultramobil kontorsprestanda. Lenovo kallar den nya Ideapad 720s ett "extremt högpresterande och tjusigt kraftpaket." Även om vi inte riktigt skulle kalla den för det så är prestandan ändå imponerande för en laptop som bara är 13 mm tunn. Vi fick i vår testrapport reda på exakt vad du kan förvänta dig av 720s i sina olika konfigurationer.

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
25 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 11 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 0.8 (minimum) to 240 (maximum) ms. » 37 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.2 ms).
       Response Time 50% Grey to 80% Grey
35 ms ... rise ↗ and fall ↘ combined↗ 17 ms rise
↘ 18 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. » 24 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.9 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 131000 Hz ≤ 90 % brightness setting

The display backlight flickers at 131000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 131000 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 10322 (minimum: 43 - maximum: 588200) Hz was measured.

Ideapad 720s från Lenovo är en väldigt lätt och ultratunn laptop för vardagligt kontorsarbete. Som en av få enheter i vårt test så kunde Ideapad 720s upprätthålla sin prestanda konsekvent utan tapp. Även under extrema förhållanden så försäkrar den bra kylningen att systemet fortfarande kan användas. Men servicemöjligheterna är begränsade och Lenovo fokuserade också på bara dom mest nödvändiga anslutningarna. Men tack vare Thunderbolt-anslutningarna så kan alla nödvändiga portar tillhandahållas av motsvarande tillbehör.

Med Lenovo Ideapad 720s får köparen en väldigt tunn och lätt laptop, som alltid kommer finnas där men aldrig kommer vara i vägen i vardagen.

Om man ser till aktuella erbjudanden så kan Ideapad 720s köpas med en Kaby Lake CPU från 8:e generationen utan att man behöver tveka. Men köpare får följa sina egna preferenser i frågan om huruvida modellerna med AMD:s Ryzen 5 2500U eller Kaby Lake-processorer från 7:e generationen är värda i fråga om pris.
