Kort testrapport Dell Latitude 7390 (Core i7-8650U, Touchscreen) Laptop

Slimmer zaken doen? Een van de beste zakelijke ultrabooks wordt met het gebruik van een 8e-generatie Core i7-8650 CPU en NVMe SSD nog krachtiger - en ook is er gelukkig een anti-glans touchscherm. Maar zijn deze wijzigingen de prijs waard? Zoals altijd onderzoeken we dit tot in detail in ons testrapport.

Responstijd Scherm

De responstijden van het scherm tonen hoe snel het scherm in staat is om van één kleur naar de andere te veranderen. Trage responstijden kunnen aanleiding geven tot 'nabeelden' rond bewegende objecten of het scherm wazig maken (blur). Vooral spelers van snelle 3D-games hebben baat bij een scherm met snelle responstijden.
       Responstijd Zwart naar Wit
30.4 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18.8 ms stijging
↘ 11.6 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 240 (maximum) ms. » 76 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (24.4 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
36.8 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18 ms stijging
↘ 18.8 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 636 (maximum) ms. » 35 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (38.7 ms) van alle geteste toestellen.

Screen Flickering / PWM (Pulse-Width Modulation)

Om de schermhelderheid te verlagen schakelen sommige laptops het backlight erg snel aan en uit. Dit gebeurt aan een dergelijk hoge frequentie dat het niet zichtbaar is voor het menselijk oog. Als de frequentie te laag is kunnen personen met gevoelige ogen geïrriteerd geraken, hoofdpijn krijgen en zelfs flickering waarnemen.
Screen flickering / PWM niet waargenomen

Ter vergelijking: 51 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 9599 (minimum: 5 - maximum: 142900) Hz waargenomen.

Contra

- onmogelijk met een hand te openen
- toegevoegde waarde van Core i7 upgrade dubieus
- vingerafdrukscanner lijkt kieskeuriger dan andere modellen
- scharnier ontwerp staat deksel toe de basiseenheid bij grote hoeken op te tillen
- oppervlaktetemperaturen bij geen belasting zijn soms te warm voor de schoot

Dit is de verkorte versie van het originele artikel. Het volledige, Engelse testrapport vind je hier.

Onze lijst van minpunten is kleiner geworden sinds ons testrapport vorige maand van de Latitude 7390, deels dankzij configuratieverschillen in het testmodel van vandaag, en deels omdat enkele minpunten wellicht eigenaardigheden waren van het specifieke testmodel. De upgrade naar een Core i7 brengt zeker een prestatiesprong met zich mee - vooral merkbaar bij langere belasting, waar de prestaties niet alleen beter zijn, maar ook consistenter. Voor de meeste gebruikers is de Core i5 meer dan krachtig genoeg en zal de lagere kostprijs mogelijk doorslaggevend zijn. Dezelfde logica geld voor de NVMe SSD (versus de conventionele M.2 SATA optie die we zagen in het Latitude 7390 testmodel van vorige maand) die sneller is, maar ook warmer wordt en voor een hogere prijs zorgt. Het meest verrassende is echter dat het anti-glans touchscherm in dit deze configuratie ook echt anti-glans is; er zijn geen negatieve verschillen in vergelijking met het conventionele (non-touch) paneel van vorige maand.

De prijs mag er dan zijn, maar er zijn maar weinig andere laptops in deze klasse die zo'n gedegen indruk maken als de Latitude 7390.

De waslijst van pluspunten zijn nog steeds van toepassing. De 7390 heeft een foutloze afwerking en stevige bouw, maar weet toch bescheiden afmetingen en een laag gewicht te houden. Onderhoud is makkelijk dankzij de verwijderbare klep aan de onderzijde. De uitgekiende selectie van poorten en robuuste beveiligingsmogelijkheden zullen door zakelijke gebruikers en IT-afdelingen gewaardeerd worden. Het toetsenbord en het touchpad in het testmodel zijn beide erg goed en het beeldscherm blijft aantrekkelijk ondanks dat dit nu een ander onderdeel is met touchfunctionaliteit. Tot slot blijft het notebook bij het meeste gebruik stil en is de batterijduur lang. Rond dit af met een 3-jaar on-site garantie en je ziet een erg sterk aanbod in het zakelijke segment.

Met $ 2.197 is deze zeker aan de prijzige kant, maar er zijn maar weinig andere laptops in zijn klasse die zo'n degelijk indruk maken als de Latitude 7390. Lenovo's X1 Carbon en HP's EliteBook Folio 1040 G4 komen waarschijnlijk het dichtst in de buurt - maar eerlijk gezicht zijn geen van deze apparaten een slechte keuze.
