Test: Dell Latitude 7490 (i7-8650U, FHD Touchscreen) Laptop (Sammanfattning)

Sam Medley (översatt av Daniel Eriksson), 04/15/2018

Samma kropp, ny motor. Dell Latitude 7490 på 14 tum behåller samma design som förra årets Latitude 7480 men har en ny fyrkärnig CPU från U-serien. Core i7-8650U är en betydande uppgradering framför det dualkärnade chip som satt i föregångaren. Berättigar ökningen i prestanda en uppgradering?

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
32.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 13.6 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. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.2 ms).
       Response Time 50% Grey to 80% Grey
48.4 ms ... rise ↗ and fall ↘ combined↗ 27.6 ms rise
↘ 20.8 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. » 80 % of all devices are better.
This means that the measured response time is worse 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 not detected

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10287 (minimum: 43 - maximum: 588200) Hz was measured.

För

+ fyrkärnig CPU ger en rejäl ökning i prestanda framför förra årets modell
+ tilltalande kolfiber-finish på locket (som tillval)
+ robust chassi
+ utmärkt tangentbord
+ massor av portar
+ Windows Precision-drivrutiner förbättrar styrplattan rejält
+ snabb prestanda på lagringen
+ utmärkt SD-kortsprestanda
+ pålitlig WiFi-styrka (tack vare ASA)
+ underhåll är tydligt och enkelt
+ ett utbud av (i huvudsak) pålitliga inloggningsalternativ
+ lågt, enhetligt fläktljud
+ batteri som håller hela dagen

Emot

- microSD-plats istället för fullstorlek
- vänstra sidan av tangentbordet blir varmt vid belastning
- styrplattan är för känslig (men kan ställas in med mjukvaran)
- inkonsekvent långtidsprestanda
- CPU stryps vid belastning

Läs den fullständiga versionen av den här recensionen på engelska här.

Dell har gjort ett utmärkt jobb med Latitude 7490, men i huvudsak på grund av att dom gjorde ett bra jobb med 7480. I princip allt har helt enkelt följt med sen förra årets modell. Den största styrkan Latitude 7490 har framför 7480 är att den inkluderar Intels fyrkärniga 8:e generation av CPU:er. Trots att dom har samma TDP på 15 W som tidigare processorer från U-serien så dubblerar nästan Kaby Lake R-modellerna prestandan jämfört med sina motsvarigheter från den 7:e generationen. Latitude 7490 är ett bra exempel på fördelarna i applikationsprestanda som går att få med en uppgradering till Kaby Lake R, men den är också ett exempel på en del av dom uppoffringar som dom nya chippen gör. Värmestrypning är ett stort problem här. Vid tung belastning så kan CPU:n använda boost fullt ut, men bara under korta stunder.

Vi ska vara uppriktiga: om du redan äger en Latitude 7480 kan du strunta i 7490. Den extra CPU-prestandan kommer bara att märkas i processor-intensiva uppgifter; om ditt arbetsflöde inte inkluderar tung användning av kalkylblad eller annat CPU-tungt arbete så är processoruppgraderingen inte värd kostnaden av en helt ny maskin. Men om du letar efter en ny företagslaptop eller vill byta ut en maskin som vid det här laget är några år gammal så borde Latitude 7490 definitivt övervägas. Dell har skapat en utmärkt maskin som kan stå emot branschens andra kämpar.
