Test: Teclast F7 Air (Sammanfattning)

Gemini Lake med snygg look.

Teclast F7 Air är en smidig och välgjord laptop som definitivt drar blicken till sig. Men en svag processor, ett mediokert tangentbord och en tråkig styrplatta gör att det finns rum för förbättring.

Display Response Times

ℹ
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
28.4 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 12.4 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 73 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
   ↔    Response Time 50% Grey to 80% Grey
32.4 ms ... rise ↗ and fall ↘ combined↗ 14.8 ms rise
↘ 17.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
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 detected 1000 Hz ≤ 99 % brightness setting

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured.

Teclast F7 Air är ett utmärkt exempel på form framför funktion. Datorn är väldesignad och ser riktigt tjusig ut, särskilt med tanke på priset (ca 4.000 kr). De flesta bärbara datorerna i det här prisskiktet ser ut som billiga plaststycken, men F7 Air påminner snarare om en 12-tums MacBook.

Men skönheten sitter bara på ytan. En Intel Celeron N4120 är för långsam och svag för något annat än enkelt kontorsarbete, epost eller lätt webbsurfande. Maskinen kan hantera en del mediaströmning, inklusive video i 4K, men det kräver tålamod och är långt ifrån perfekt.

Lägg därtill dålig batteritid, ett osmakligt tangentbord samt en tråkig skärm (innan kalibrering) och kompromisserna blir väldigt tydliga. Det finns en del bra saker här, i huvudsak estetiken och konstruktionskvaliteten. Men det finns också alldeles för många brister för att vi ska kunna rekommendera den.

I slutändan möter Teclast F7 Air samma öde som andra billiga budgetlaptops. Den är inte tillräckligt kraftfull för annat än enkla uppgifter. Om du vill ha en vacker laptop och inte bryr dig om eller behöver kraftfull hårdvara kan Teclast F7 Air vara prisvärd. Men en enkel maskin till liknande pris med en Intel Core i3- eller AMD Ryzen 3 CPU kommer vida överträffa F7 Air.
