Lenovo Ideapad 720S-13IKB (i5-8250U, UHD 620) Laptop rövid értékelés

Mike Wobker, 👁 Sebastian Jentsch, Tanja Hinum (fordította Tamás Somogyi), 02/08/2018
Laptop / Notebook

Ultramobil irodai erőgép. A Lenovo az új Ideapad 720s-t egy "extrém nagy teljesítményű és stílusos erőgép"-nek nevezi. Ugyan azért ezt nem mondanánk rá, de a teljesítménye egy alig 13 mm (~0.51 in) vastag notebookhoz képest elég komoly. Cikkünkből kiderül, hogy mire számíthatunk a 720s különböző konfigurációitól.

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. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.7 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. » 25 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.1 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 131 Hz ≤ 90 % brightness setting

The display backlight flickers at 131 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 131 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8689 (minimum: 43 - maximum: 142900) Hz was measured.

A Lenovo Ideapad 720s egy nagyon könnyű, ultravékony notebook mindennapi irodai feladatokra. Ezen kívül az Ideapad 720s egyike azon kevés általunk tesztelt készüléknek, amelyek képesek egyenletesen fenntartani a teljesítményüket. A remek hűtés még extrémebb körülmények között is gondoskodik róla, hogy a rendszer használható maradjon. Ugyanakkor a karbantartási lehetőségei korlátozottak, és a Lenovo csak a legszükségesebb csatlakozókkal látta el. Hála a Thunderbolt-nak, egyéb szükséges csatlakozókat a megfelelő perifériával biztosítani tudjuk.

A Lonovo Ideapad 720s megvásárlói egy nagyon vékony és könnyű notebookra tehetnek szert, amely mindig rendelkezésre áll, de soha nem akadályoz a mindennapok során.

Jelenlegi verziói közül az Ideapad 720s 8. generációs Kaby Lake CPU-s változatát gondolkodás nélkül érdemes megvenni. Azt viszont, hogy az AMD Ryzen 5 2500U-s, vagy a 7. generációs Kaby Lake processzoros változata megéri-e az ára miatt, mindenkinek az egyéni igényei döntik el.
