Kort testrapport Lenovo Ideapad 720S (Ryzen 2500U, Vega 8) Laptop

Mike Wobker, Felicitas Krohn, 16-03-2018

AMD-update. We hebben Lenovo's IdeaPad 720s eerder al getest en zagen een dunne, lichtgewicht notebook voor alledaagse taken. Het 13-inch notebook is nu ook beschikbaar met een AMD Ryzen 5 2500U processor als alternatief voor de Intel SKU.

Responstijd Scherm

De responstijden van het scherm tonen hoe snel het scherm in staat is om van één kleur naar de andere te veranderen. Trage responstijden kunnen aanleiding geven tot 'nabeelden' rond bewegende objecten of het scherm wazig maken (blur). Vooral spelers van snelle 3D-games hebben baat bij een scherm met snelle responstijden.
       Responstijd Zwart naar Wit
26 ms ... stijging ↗ en daling ↘ gecombineerd↗ 14 ms stijging
↘ 12 ms daling
Het scherm vertoonde relatief trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 240 (maximum) ms. » 46 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (25.6 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
36 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18 ms stijging
↘ 18 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 27 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd beter is dan het gemiddelde (41 ms) van alle geteste toestellen.

Screen Flickering / PWM (Pulse-Width Modulation)

Om de schermhelderheid te verlagen schakelen sommige laptops het backlight erg snel aan en uit. Dit gebeurt aan een dergelijk hoge frequentie dat het niet zichtbaar is voor het menselijk oog. Als de frequentie te laag is kunnen personen met gevoelige ogen geïrriteerd geraken, hoofdpijn krijgen en zelfs flickering waarnemen.
Screen flickering / PWM waargenomen 128000 Hz ≤ 90 % helderheid instelling

Het backlight van het scherm flikkert aan 128000 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 90 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 128000 Hz is redelijk hoog en de meeste mensen die gevoelig zijn aan flickering zouden dit dus niet mogen waarnemen of geïrriteerde ogen krijgen.

Ter vergelijking: 53 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 8964 (minimum: 43 - maximum: 142900) Hz waargenomen.

Dit is de verkorte versie van het originele artikel. Het volledige, Engelse testrapport vind je hier.

Ons testrapport laat duidelijk zijn dat het nemen van een bestaand notebookontwerp en het vervangen van de Intel CPU door een AMD Ryzen 5 2500U niet voldoet. Als Lenovo wat tijd en moeite zou steken in het aanpassen van het koelsysteem aan de gloednieuwe AMD CPU, dan had de Ryzen-gebaseerde IdeaPad 720s daadwerkelijk een goed alternatief kunnen vormen voor Intel's achtste generatie Core processoren.

De AMD-gebaseerde IdeaPad 720s is een solide en krachtige notebook die last heeft van de zeer slechte en onvoldoende koeling.

Toch blijft de geteste AMD SKU van Lenovo's IdeaPad 720s een fatsoenlijke zakelijk notebook met voldoende spierballen voor alledaagse kantoortaken en normale multimedia uitdagingen. We hadden verwacht dat de prestaties beter zouden zijn dan de recent geteste Intel SKU; helaas wordt het notebook slachtoffer van het falen van Lenovo om het apparaat op een juiste manier aan te passen aan AMD's CPU.
