Brand: Lenovo

Svagt bröst. Trots att dom nya Intel-processorerna representerar den största prestandaökningen på åratal så är Lenovo Yoga 520-14IKB fortfarande utrustad med äldre Kaby Lake-processorer. I detta utförliga test kan du få reda på varför denna omvandlingsbara inte fick vår slutgiltiga rekommendation.

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

347 Hz

≤ 90 % brightness setting

The display backlight flickers at 347 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 347 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

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
34 ms ... rise ↗ and fall ↘ combined	↗ 20 ms rise
34 ms ... rise ↗ and fall ↘ combined	↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 90 % 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
47 ms ... rise ↗ and fall ↘ combined	↗ 24 ms rise

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. » 79 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms).

För

+ funktionellt hölje i aluminium och plast

+ väldigt bra styrplatta

+ lämpligt tangentbord

+ aktiv penna inkluderad

+ håller sig alltid sval och nästan alltid tyst

+ bättre batteritid tack vare större batteri

Emot

- CPU:n använder inte sin fulla kapacitet

- skärmen: låg ljusstyrka och färgrymdstäckning, konstig krusningseffekt, PWM

- USB-C utan DisplayPort eller energileverans

- gångjärnen är för lösa

- 1x1 WLAN

- utdaterade GPU- och CPU-alternativ

Som vi redan har nämnt i sektionen om höljet så ser Yoga 520-14IKB väldigt mycket ut som IdeaPad 520s-14IKB. Detta gäller inte bara designen utan också hårdvaran i allmänhet. Lenovo Yoga 520-14IKB är nästan en omvandlingsbar version av IdeaPad.

På grund av det är listan över för och nackdelar också väldigt lik. Precis som med IdeaPad är höljet, tangentbordet och styrplattan på en bra nivå. Även om dyrare enheter till viss del kan vara betydligt bättre här så går det, med tanke på priset, knappast att begära mer av Yoga, som inte har några egentliga svagheter i dessa kategorier. Detsamma kan sägas om ljudnivån och temperaturutvecklingen. Yoga 520-14IKB håller sig alltid sval och tyst. Vidare, tack vare ett större batteri, har batteritiden förbättrats drastiskt jämfört med föregångaren.

Vi finner den första skillnaden jämfört med IdeaPad 520s-14IKB i temperaturutvecklingen. Medans IdeaPad blir en aning varmare (också på grund av Nvidia GPU:n, förstås) så håller sig Yoga 520 alltid sval. Detta beror också på dess första stora nackdel: CPU-prestandan är kraftigt begränsad och förblir långt ifrån den teoretiska maxnivån hos Core i5-7200U. Denna prestandabegränsning är på grund av tillverkarens TDP-begränsning av 8 watt till CPU:n. Så det är på så sätt knappast konstigt att höljet knappt blir varmt. En annan negativ punkt är skärmen. Även om den erbjuder tryckkänslighet och en aktiv penna så är kvaliteten på färgerna dålig tack vare den begränsade färgrymden. Ljusstyrkan är också för låg för att kompensera för den skinande ytan vid utomhusbruk. Men vi irriterades särskilt av den konstiga vågeffekten som kan ses när man tittar närmare på skärmen samt av den låga PWM-frekvensen. Utöver dessa svagheter, precis som med IdeaPad, så saknade vi här en USB-C anslutning som hanterar mer än USB. Vidare är gångjärnen för svajiga för vår smak. Tillslut, som med IdeaPad 520s-14IKB, så måste vi klaga på dess 1x1 WLAN.

Skärmens svagheter och den dåliga CPU-prestandan kombinerad med åldrande komponenter gör Yoga 520-14IKB en omvandlingsbar som knappast kan rekommenderas.

På grund av dessa svagheter är det svårt för oss att rekommendera Yoga 520-14IKB. Det är särskilt svagheterna hos skärmen och CPU-prestandan som väger tungt. Till det kommer faktum att Yoga 520-14IKB helt enkelt är föråldrad, då GPU-tillvalet samt dess CPU redan har efterföljare. Därför är vår rekommendation att antingen välja en annan omvandlingsbar eller vänta på en uppdatering av Yoga med Kaby Lake Refresh och MX150. Kanske blir den då också bättre i fråga om skärm och CPU-prestanda.
