Test: Lenovo Yoga C930-13IKB (i7-8550U, FHD) Omvandlingsbar (Sammanfattning)

Allen Ngo, 👁 Allen Ngo (översatt av Daniel Eriksson), 10/29/2018

Mångsidigare än någonsin. Vi undersöker den dyrare Core i7 SKU:n för att se hur den står sig gentemot den billigare Core i5 SKU:n. Är det värt att lägga pengarna på det snabbare alternativet? Och hur mycket bättre är det snabbare alternativet egentligen?

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
25.6 ms ... rise ↗ and fall ↘ combined↗ 15.6 ms rise
↘ 10 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 0.8 (minimum) to 240 (maximum) ms. » 44 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
34.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 15.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 24 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8929 (minimum: 43 - maximum: 142900) Hz was measured.

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

Hur mycket snabbare är Core i7 SKU:n av Yoga C930 jämfört med Core i5 SKU:n? Förvänta dig en prestandaökning på 20% ren CPU-styrka när båda systemet jämförs vid tung belastning. Core i7 SKU:n är bättre på att upprätthålla Turbo Boost-klockfrekvenser i längre perioder utan att det behöver påverka batteritiden för vardagsuppgifter såsom surfande, strömning och ordbehandling. Vet man att man kan utnyttja de extra hästkrafterna kan man dra nytta av den dyrare konfigurationen.

För alla andra är skillnaden i prestanda mellan Core i5- och Core i7-varianterna omärkbar. Core i5-8250U är fullt tillräcklig för surfande, strömning och multitasking. Det är istället grafiken som är den svagaste aspekten av Yoga C930 då serien fortsatt saknar alternativ för Iris eller dedikerad Nvidia-grafik. Det är troligen den begränsade grafikprestandan vid bild eller videoredigering som kommer att märkas, snarare än den minimala skillnaden mellan Core i5 och Core i7.

Yoga C930 närmar sig sakta att bli en konsument/företags-hybrid med sin portabla design och onekligen användbara aktiva stylus. Grundläggande kontorsarbete eller hemunderhållning kommer fungera utmärkt på Core i5 SKU:n, även jämfört med Core i7. Den som behöver mer grafikhästkrafter bör dock istället överväga MateBook X ProMSI PS42 eller XPS 13 med Iris-grafik.
