Test: Lenovo ThinkPad T490: En företagslaptop med lång batteritid och en iGPU

Benjamin Herzig, 👁 Andreas Osthoff (översatt av Daniel Eriksson), 06/25/2019

Bättre utan NVIDIA? Vi är väl bekanta med ThinkPad T490 eftersom vi recenserade modellen med en GPU från NVIDIA senast förra månaden. Nu är det dags att utsätta modellen med en Intel-GPU för våra tester, men hur kommer datorn att prestera utan en dedikerad GPU? Läs vidare i vår detaljerade recension för att få reda på det.

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
44.8 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 23.6 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. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.2 ms).
       Response Time 50% Grey to 80% Grey
71.2 ms ... rise ↗ and fall ↘ combined↗ 33.2 ms rise
↘ 38 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. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (40.2 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 2427 Hz ≤ 50 % brightness setting

The display backlight flickers at 2427 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 2427 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9439 (minimum: 43 - maximum: 142900) Hz was measured.

Lenovo ThinkPad T490 är en utmärkt företagslaptop med eller utan GPU från NVIDIA. Modellen utan NVIDIA-chippet är på en del områden en aning bättre än den mer tekniskt kapabla varianten av T490, vilket ökar poängsumman till 91% istället för de 90% vi gav dess MX250-utrustade syskon.

Bland annat kan nämnas att vår recensionsenhet hade bättre batteritid än ThinkPad T490-modellen med dedikerad GPU. Den förstnämnda höll sig dessutom svalare och led inte av det irriterande högtalarljudet som plågade vår första recensionsenhet. Lenovo har i princip eliminerat detta helt med en BIOS-uppdatering, så det bör inte längre påverka någon variant av ThinkPad T490.

Vidare stryps inte Intel-versionen av T490 i vårt stresstest, tack vare en till namnet svagare CPU. De övriga höjdpunkterna från vårt första test av T490 gäller också här och inkluderar ett robust och lätt hölje, fantastiska inmatningsenheter och en ljusstark skärm med god färgprecision. Vi uppskattade också det mångsidiga portutbudet samt att CPU-prestandan låg över genomsnittet. 

Båda modellerna lider dock av i stort sett samma brister. Den energieffektiva skärmen har dåliga responstider och det är synd att det är en microSD-kortläsare som ingår istället för en i full storlek. På samma sätt förstår vi inte varför Lenovo bara låter Thunderbolt 3-porten använda två PCIe-banor, även om det är trevligt att en Thunderbolt 3-port ingår. Vidare är det svårt att ta isär och sätta ihop höljet och avsaknaden av Power Bridge-funktionen gör T490 mindre flexibel än sina föregångare.

Svalare och mer uthållig: Intel GPU-varianten av Lenovo ThinkPad T490 är på en del områden bättre än syskonet med en GPU från NVIDIA och är totalt sett en fantastisk företagslaptop.

Sammanfattningsvis bör T490 med en Intel-GPU vara mer än tillräcklig för den som inte behöver den extra grafikkapaciteten som kommer av ett GeForce MX250. Men om du ibland spelar spel efter jobbet eller behöver en laptop som du kan redigera video på är däremot T490 med en NVIDIA-GPU i vårt tycke ett bättre val.
