Kort testrapport Dell Latitude 7400 2-in-1 (i7-8665U) Convertible

Steve Schardein, 👁 Allen Ngo, 08-06-2019

Vuur aan de schenen. De premium zakelijke modellen van Dell zijn nog nooit zo XPS-achtig geweest, maar met de grote veranderingen komen aanzienlijke uitdagingen. Met zijn Core i7-8665U CPU, 16 GB RAM en NVMe SSD, is de € 2800 Latitude 7400 2-in-1 zeker niet de langzaamste, maar kan deze de hitte wel aan? Je leest het in dit testrapport.

Responstijd Scherm

ℹ
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
38 ms ... stijging ↗ en daling ↘ gecombineerd↗ 22.8 ms stijging
↘ 15.2 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. » 95 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (25.1 ms) van alle geteste toestellen.
   ↔    Responstijd 50% Grijs naar 80% Grijs
56 ms ... stijging ↗ en daling ↘ gecombineerd↗ 31.6 ms stijging
↘ 24.4 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 91 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (40 ms) van alle geteste toestellen.

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
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 waargenomen 1667 Hz ≤ 24 % helderheid instelling

Het backlight van het scherm flikkert aan 1667 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 24 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 1667 Hz is redelijk hoog en de meeste mensen die gevoelig zijn aan flickering zouden dit dus niet mogen waarnemen of geïrriteerde ogen krijgen.

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 9418 (minimum: 43 - maximum: 142900) Hz waargenomen.

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

De Dell Latitude 7400 2-in-1 (€ 2800 in de geteste configuratie) vertegenwoordigd een substantieel andere design-filosofie voor de zakelijke convertibles van de fabrikant. Laten we beginnen met de algemene voordelen: dit is mogelijk de meest aantrekkelijke Latitude tot nu toe, met zijn prachtige geborstelde aluminium behuizing, precieze CNC-gefreezde randen en hoeken en de superslanke beeldschermranden. Het notebook kan makkelijk verward worden met de XPS-familie notebooks.

Maar met deze transitie poogt de Latitude de vele praktische zaken voor zakelijke notebooks te behouden die reeds lang de fundering van het succes van dit merk zijn: makkelijk onderhoudt, duurzame behuizing, lange batterijduur, stille werking en premium invoerapparaten. Het aanbod van poorten is wel wat aangetast, USB Type-C/Thunderbolt 3 oplaadpoorten zijn aanwezig, maar de Ethernetpoort is verdwenen. De gemiddelde zakelijke gebruiker zal meer dan voldoende hebben om hun werk te kunnen doen. De audio is aanzienlijk verbeterd ten opzichte van de vorige Latitude machines. En tot slot is de batterijduur van ons testmodel, dat uitgerust is met een 78 Wh-batterij, makkelijk genoeg voor een volle werkdag zonder oplader.

De Latitude 7400 2-in-1 is een ambitieuze revisie in een markt die typisch erg conservatief is en vooruitgang in kleine stappen de standaard is. In sommige opzichten is het notebook een verfrissende stap, maar het is niet zonder problemen.

Hoewel de behuizing op het oog en haptisch erg fraai is, zijn niet alle beoordelingen van de behuizing zonder meer positief. Het beeldscherm, hoewel binnenshuis aantrekkelijk, heeft last van een zwakke helderheid en is uiterst reflecterend. Gebruik buiten is daarmee oncomfortabel en in vele gevallen simpelweg onmogelijk. De stap naar een glazen touchpad is leuk, maar sommige zakelijke gebruikers zullen de stap van fysieke touchpad knoppen naar een geintegreerd "clickpad" minder plezant vinden. Het RAM is nu compleet gesoldeerd op het toetsenbord en upgraden of vervangen is dus onmogelijk. De M.2 NVMe SSD kan nog wel steeds vervangen worden.

Maar de grootste tekortkoming van ons testmodel is de neiging tot hoge interne temperaturen, die al snel teveel wordt voor het ondermaatse koelsysteem en resulteert in gloeiendhete oppervlakte temperaturen en potentieel de CPU prestaties verminderd. Het doet je overvragen waarom er een hongerige en hete Core i7 Whiskey Lake SoC gebruikt wordt in een dergelijke compacte behuizing met zijn kleine, conservatief afgestelde koelsysteem.

We zouden graag genoegen nemen met een hoger systeemgeluid als dat betekend dat de prestaties beter volgehouden kunnen worden en de behuizing temperaturen lager blijven. Dit kan tot op zekere hoogte bereikt worden door het Ultra Performance profiel te selecteren in de Dell Power Manager software - dit geeft in elk geval iets hogere resultaten in Cinebench R15. Hopelijk zal een toekomstige firmware update dit standaard maken, want de gemiddelde gebruiker zal niet snel bekend zijn met deze optie. Toch denken we dat het logischer zou zijn om de kosten omlaag te brengen en een minder dure Core i5 CPU configuratie te kiezen, waarvan ook de temperaturen lager zijn en je niet een premium betaald voor marginaal hogere prestaties.

De voornaamste concurrentie bestaat uit de HP EliteBook x360 1040 G5 en Lenovo ThinkPad X1 Yoga. De Asus Zenbook Flip 14 is ook een optie, maar die doet het minder goed dan de twee voorgenoemde notebooks in onze tests. En het is het wellicht waard om nog even af te wachten of Dell een firmware update gaat uitbrengen voor de 7400 2-in-1 die de genoemde issues met de koeling oplost. Het is in vele opzichten een fantastisch notebook - maar qua koelsysteem waren de ambities misschien net wat te hoog.
