Test: Lenovo ThinkPad T480 (Core i7-8650U, FHD) Laptop (Sammanfattning)

Steve Schardein (översatt av Daniel Eriksson), 07/24/2018

Tänk en gång till. Idag tar vi en titt på vår andra konfiguration av T480, den här gången med en Core i7-8650U, 512 GB NVMe SSD och en tryckkänslig FHD-skärm — till ett lägre pris än tidigare: straxt över 17.000 kronor. Kan denna reviderade konfiguration ta hand om affärerna?

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
30.8 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 12.8 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. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
39.2 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 17.2 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. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.4 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 8895 (minimum: 43 - maximum: 142900) Hz was measured.

För

+ väldigt bra allmän systemprestanda
+ genomtänkt design med smarta tillägg
+ brett portutbud
+ tyst drift
+ inbyggd tryckkänslig skärm med bra kontrast
+ utmärkta inmatningsenheter
+ konfiguration med dubbelt batteri som möjliggör byte under körning

Emot

- underligt låg CPU-prestanda jämfört med T480s och tidigare variant av T480
- väldigt dålig färgtäckning och inexakt färgåtergivning
- vid belastning uppstår varma områden på undersidan
- skärmlocket vrider sig lätt
- hörbara knarrande/poppande ljud från höljet när man trycker mot det nedersta vänstra hörnet (vid smartcard-läsaren)
Recenseras: Lenovo ThinkPad T480
Recenseras: Lenovo ThinkPad T480

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

Likt tidigare förblir Lenovos aktningsvärda ThinkPad T480 en toppmodell på företagsmarknaden. Den är resultatet av många års förfining och noggrann revidering och kan bara matchas av en handfull riktiga topp-maskiner. Som vi påpekade i vår senaste recension är konstruktionen för det mesta riktigt gedigen, designen är som alltid praktisk (och omedelbart igenkännbar) och ett bra utbud av portar finns på plats. Inmatningsenheterna är också väldigt bra, maskinen är tyst vid drift och den är dessutom snabb — åtminstone när det gäller allmän systemprestanda jämfört med den genomsnittliga CPU-prestandan i den här kategorin.

Det som har förbättrats med dagens modell jämfört med den tidigare är främst priset, som för tillfället ligger på runt 17.000 kronor. Utöver det så är temperaturnivåer och energiförbrukning långt under dom värden vi uppmätte hos den tidigare modellen, då den här konfiguration saknar dedikerad grafik — men trots detta finns det vid belastning några problematiska varma områden på maskinens undersida. Skärmen är fortfarande ljusstark och har bra kontrast, men likt tidigare är färgtäckningen sorgligt inexakt, vilket leder till tråkiga urvattnade färger och slapp bildkvalitet.

Även om den vacklar när det kommer till skärmens färgkvalitet och några andra enstaka egenskaper så är Lenovos aktningsvärda ThinkPad T480 fortfarande är av dom bästa modellerna som tävlar på företagsmarknaden. Den är ett resultat av många års förfining och noggrann revidering och kan bara kan matchas av en handfull riktiga topp-maskiner.

Till skillnad från MX150-varianten så kan den här maskinen (förstås) inte riktigt hantera någon form av tungt GPU-arbete, inte ens lätt spelande. Detta hade vi förväntat oss — men vad vi inte hade förväntat oss var att vi skulle få lägre CPU-prestanda från vår testenhets Core i7-8650U jämfört med den billigare Core i7-8550U som satt i modellen i testade i Mars. Kanske märkligast av allt är den veritabla ravin som separerar CPU-prestandan från T480s och dagens T480; även med den senaste BIOS-versionen och alla energi-inställningar korrekt inställda så kunde vi inte uppnå poäng som hamnar i närheten av vad vi fick från vår Core i5-utrustade T480s i förra veckan.

Men även om den vacklar när det kommer till skärmens färgkvalitet och några andra enstaka egenskaper så förblir T480 värd att nämna bland respekterade konkurrenter som Dells Latitude 7490, HP:s Elitebook 840 G5 och Lenovos egna X1 Carbon. Det riktiga valet rör huruvida T480 eller T480s passar dina syften bäst — men bortsett från tidigare nämnda krångel så är det svårt att hitta några större fel på något av dessa alternativ.
