Test: Dell XPS 13 9370 (i7-8550U, 4K UHD) Laptop (Sammanfattning)

Bernie Pechlaner (översatt av Daniel Eriksson), 04/28/2018

En bråkdel...bättre? Jämfört med sitt i5-utrustade syskon så har i7-versionen av den attraktiva XPS 13 9370 - den här gången med dubbelt så mycket hårddiskutrymme och dubbelt så mycket RAM - inte en tillräckligt stor ökning i prestanda. Varför det är så är en av frågorna vi ska försöka besvara i vår recension.

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 ms ... rise ↗ and fall ↘ combined↗ 24.4 ms rise
↘ 19.6 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. » 97 % 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
69.6 ms ... rise ↗ and fall ↘ combined↗ 32.4 ms rise
↘ 37.2 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. » 97 % 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 detected 3759 Hz ≤ 20 % brightness setting

The display backlight flickers at 3759 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 3759 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 10287 (minimum: 43 - maximum: 588200) Hz was measured.

Så är XPS 13 9370 med i7-processor ett bättre val än sitt billigare syskon med en i5 CPU? Vid det här laget kan frågan bara besvaras med ett klart "nej". Bortsett från batteritiden - som förvånansvärt nog slår den hos i5 UHD-modellen - så är prestandan hos den specifika XPS 13 som vi recenserat lite av en besvikelse. Med det vill vi inte säga att dess i7-8550U nödvändigtvis presterar särskilt mycket sämre här än på någon annan laptop, men faktum kvarstår att den i7-baserade XPS 13 9370 inte riktigt kan distansiera sig själv från vår tidigare recenserade modell med en i5 CPU, som kostar tusentals kronor mindre. Det är möjligt att vi har fått tag på en defekt enhet - dom blå skärmarna och den olyckliga systemkraschen gör det onekligen till en trolig förklaring. Om vi får chansen att recensera en ersättningsmodell vid senare tillfälle kommer vi följaktligen att uppdatera den här recensionen.

Med det sagt, XPS 13 9370 är definitivt en behaglig vardagskollega med en utmärkt skärm - bortsett från dom långsamma responstiderna - och den har totalt sett bra ergonomi. I synnerhet fläktkontrollen har genomförts med perfektion, då yttemperaturerna vid normal användning samt låg till medelanvändning håller sig bekväma och ljudnivån är mycket stabilare och mindre påfallande än vi brukar vänta oss från tunna och lätta modeller.

XPS 13 9370 med i7-8550U är bara ett tilltalande val om en större SSD-enhet och maximalt med RAM är dom viktigaste faktorerna. En i5-modell med 16 GB RAM och 512 GB SSD hade fått vår röst varje gång, men för tillfället erbjuder inte Dell en sådan konfiguration.
