Test: Dell Latitude 7390 2-i-1 (i7-8650U, FHD) Omvandlingsbar (Sammanfattning)

Steve Schardein (översatt av Daniel Eriksson), 03/27/2018

Professionell omvandlingsbar… Det finns mycket att gilla med Latitude 7390 2-i-1, som dess fyrkärniga Core i7-8650U CPU, NVMe SSD, robusta hölje med kompakt fotavtryck och möjlighet till dubbel lagring. Men den bär också med sig sin beskärda del av nackdelar — och den är ganska dyr.

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
30.4 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 14 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. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.3 ms).
       Response Time 50% Grey to 80% Grey
48.8 ms ... rise ↗ and fall ↘ combined↗ 23.6 ms rise
↘ 25.2 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. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (42.1 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9953 (minimum: 43 - maximum: 588200) Hz was measured.

För

+ robust, attraktiv konstruktion
+ väldigt bra inmatningsenheter
+ allmänt snabb systemprestanda
+ relativt lätt att underhålla
+ utmärkt portutbud
+ litet fotavtryck
+ kapabel till dubbel lagring (2 st M.2 SSD)

Emot

- Core i7-alternativet ger få fördelar utöver den enkelkärniga prestandan
- maskinen är ganska tung i toppen tack vare tjockare skärmlock
- skärmen är kraftigt reflekterande/blank
- medioker färgtäckning och noggrannhet
- aningen tung för sin storlek
- nyttan av en omvandlingsbar design i en typisk företagsmiljö kan ifrågasättas

Latitude 7390 2-i-1 är en välbyggd, robust och attraktiv maskin med väldigt bra inmatningsenheter och allmänt snabb systemprestanda. Den kommer också med utmärkta anslutningsmöjligheter, är lätt att underhålla och har ett fotavtryck som är mindre än genomsnittet för sin klass. Särskilt imponerande är alternativet för duallagring, vilket möjliggörs av den lediga WWAN-platsen, som också kan inhysa en M.2/NVMe 2230 SSD. Men även om CPU-prestandan är ganska mycket snabbare än jämförbara maskiner från den tidigare generationen så ser vi få saker som rättfärdigar Core i7-konfigurationen som vi har fått som recensionsex. Istället skulle vi, om det inte bara är enkeltrådade applikationer som står på agendan, rekommendera att köra på en billigare Core i5-konfiguration istället.

Latitude 7390 2-i-1 är en välbyggd, robust och attraktiv maskin med väldigt bra inmatningsenheter och allmänt snabb systemprestanda. Men den har ett antal nackdelar och det är verkligen inte en liten investering — så innan du dyker in rekommenderar vi verkligen att du spanar runt lite.

Vidare så hålls 7390 2-i-1 tillbaka av ett antal frågetecken. Det finns bara blanka tryckkänsliga skärmar tillgängliga för konfiguration och ingen av dom är särskilt imponerande när det kommer till färgtäckning — åtminstone inte jämfört med ledarna i denna kategori såsom ThinkPad X1 Carbon. NVMe SSD-enheten vi fick i vår enhet kunde knappast hålla jämna steg med toppskiktsenheter såsom Samsungs motsvarigheter. Maskinen är ganska tung för sin storlek och på grund av dess tjockare och jämförelsevis tunga skärmlock så känns den inte riktigt så stabil i knät som vi hade önskat. Till sist finns alltid frågan om huruvida dom flesta i en företagsmiljö verkligen behöver dom omvandlingsbara funktionerna som erbjuds av dessa Yoga-aktiga maskiner. Dell har redan ett fullt kapabelt och extremt välbalanserat alternativ i sin konventionella Latitude 7380 (och även om vi ännu inte recenserat den, troligen också 7390) — och den kan utrustas med en reflektionsbeständig skärm, är lättare och känns totalt sett mer stabil när den står på något.

Andra maskiner som är värda att överväga (utöver dom konventionella Latitude 7380/7390) är den utomordentliga ThinkPad X1 Carbon 2018 och Asus Zenbook 13 UX331UA. För ca 17 000 kronor (som konfigurerad här) är Latitude 7390 2-i-1 verkligen inte en liten investering — så innan du dyker in rekommenderar vi verkligen att du spanar runt lite.
