Test: Dell Latitude 5491 (8750H, MX130, FHD) Laptop (Sammanfattning)

Bernie Pechlaner (översatt av Daniel Eriksson), 07/31/2018

Sex kärnor för företagsbruk. Dells mittenskikts-serie Latitude 5000 får en Coffee Lake H-behandling och dedikerad grafik. Den nya modellen på 14 tum med en processor på 45 W och GeForce-grafik presterar bättre än sitt syskon med ULV-processor, men det ökade energiuttaget resulterar i mer värme och kortare batteritid. Skärmen imponerar fortfarande inte.

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
28.4 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 12 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. » 66 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 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 0.9 (minimum) to 636 (maximum) ms. » 39 % of all devices are better.
This means that the measured response time is similar to 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8677 (minimum: 43 - maximum: 142900) Hz was measured.

Latitude 5491, Recensionsex från Dell USA

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

Latitude 5491 med en sexkärnig i7-8550H CPU och Nvidia GeForce MX130-grafik presterar bättre än Latitude 5490-modellerna med ULV CPU:er och integrerad grafik - ibland med stor marginal. Det förstås, för att kunna dra nytta av dom två extra CPU-kärnorna behöver program vara designade för att använda de extra trådarna. Utöver en rejäl ökning i prestanda så bockar Latitude 5491 av alla korrekta rutor då den fortfarande är samma väldesignade och säkra företagslaptop med utmärkta inmatningsenheter och god ergonomi.

Med det sagt så finns det fortfarande rum för förbättring: nya Latitude blir väldigt varm vid belastning och på grund av det är den sämre på att upprätthålla turbo boost. Fläktarna behöver jobba hårdare så systemet låter mer än tidigare. Dell har också valt att använda samma blanka tryckkänsliga FHD-skärm som Latitude 5490 är utrustad med. Panelen lämnar mycket att önska, då ljusstyrkan är alldeles för låg för att den ska kunna användas utomhus och både färgomfång och färgnoggrannhet misslyckas med att imponera. Dessutom kommer den här modellen med en större och mycket tyngre nätadapter och den håller inte lika länge på en laddning.

Vägkrigare som i huvudsak fokuserar på ordbehandling, kalkylblad och webbsurfande kommer troligen klara sig bättre med Latitude 5490, som har längre batteritid och inte blir i närheten lika varm och högljudd. Den som är nöjd med prestandan en ULV CPU kan erbjuda borde även överväga Lenovos utmärkta ThinkPad T480 eller T480s.
