Kort testrapport Lenovo ThinkPad T480 (Core i7-8650U, FHD) Laptop

Steve Schardein (vertaald door Siemon Boes), 21-07-2018

Denk opnieuw. Vandaag nemen we onze tweede configuratie van de T480 onder de loep: deze keer met een Core i7-8650U, 512 GB NVMe-SSD en een FHD-touchscreen. En dit voor iets meer dan 1700 euro - een lagere prijs dan voordien. Is deze herziene configuratie een succes?

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
30.8 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18 ms stijging
↘ 12.8 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 240 (maximum) ms. » 78 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (25.9 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
39.2 ms ... stijging ↗ en daling ↘ gecombineerd↗ 22 ms stijging
↘ 17.2 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 42 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (41.4 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: 54 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 8895 (minimum: 43 - maximum: 142900) Hz waargenomen.

Pro

+ erg goede systeemprestaties
+ slim ontwerp met handige extra's
+ diverse selectie aan poorten
+ stil in gebruik
+ geïntegreerd touchscreen met prima contrast
+ uitstekende invoerapparatuur
+ configuratie met twee batterijen laat hot swapping toe

Contra

- vreemd genoeg lagere CPU-prestaties dan T480s en vorige T480
- erg zwakke kleurdekking en -nauwkeurigheid
- lokaal erg warme punten aan onderzijde bij belasting
- scherm gevoelig voor wringing
- hoorbaar gekraak wanneer je drukt op de linkeronderhoek (vlak naast smartcard-lezer)

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

Net als voorheen blijft de gerespecteerde ThinkPad T480 een topkeuze binnen de zakelijke sector. De laptop is het product van jarenlang verfijning en zorgvuldige revisie en moet zich enkel meten met een handvol machines van de bovenste plank. Zoals reeds vermeld in ons vorig testrapport is de bouwkwaliteit uitstekend, het ontwerp erg handig (en vertrouwd) en zijn er meer dan genoeg poorten. De invoerapparatuur presteert eveneens goed en de machine is stil - en snel - in gebruik, tenminste wat algemene prestaties betreft en binnen de context van een zakelijk toestel.

De verbeteringen van dit model ten opzichte van de vorige versies beginnen bij de prijs, die momenteel rond de 1700 euro hangt. Daarnaast liggen temperatuur en energieverbruik een stuk onder de waarden die we waarnamen bij het vorige model - aangezien deze configuratie een discrete GPU mist - al zijn er bij belasting lokaal toch een aantal problematische warme punten aan de onderkant van het toestel. Het scherm is nog altijd helder en contrastrijk, maar de kleurweergave laat veel te wensen over, wat aanleiding geeft tot vage kleuren en teleurstellende beeldkwaliteit.

Hoewel de Lenovo ThinkPad T480 steken laat vallen op het vlak van schermkwaliteit en een aantal kleinere categorieën, blijft het toestel een topper binnen het zakelijke marktsegment. Het is een product van jarenlang verfijning en zorgvuldige revisie dat zich enkel moet meten met een handvol machines van de bovenste plank.

In tegenstelling tot de configuratie met MX150 kan dit toestel (uiteraard) niet goed om met zware GPU-taken zoals gaming. Dit viel te verwachten - maar wat niet te verwachten viel is de lagere CPU-performance die de Core i7-8650U ons bood ten opzichte van de goedkopere Core i7-8550U in het model van maart. Het vreemdst van al is wellicht de kloof in CPU-prestaties die de T480s scheidt van de T480 van vandaag; zelfs met de nieuwste BIOS en alle prestatie-instellingen juist geconfigureerd, slaagden we er niet in om scores te halen die in de buurt komen van wat we vorige week zagen bij onze T480s met Core i5.

Hoewel de T480 steken laat vallen op het vlak van schermkwaliteit en een aantal kleinere categorieën, is hij zeker het overwegen waard als je hem vergelijkt met respectabele concurrenten als de Dell Latitude 7490, de HP EliteBook 840 G5 en Lenovo's eigen X1 Carbon. In feite komt het erop neer welk toestel heet meest aansluit bij het gewenste gebruiksscenario: de T480 of de T480s - maar afgezien van de vermelde minpunten is het moeilijk om echt ernstige tekortkomingen te vinden in beide opties.
