Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 1000 Hz | ≤ 25 % brightness setting | |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 25 % 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. |

Aktuella SKU:er för XPS 15 9560 inkluderar Core i5-7300HQ och Core i7-7700HQ i likhet med hur det aktuella utbudet av SKU:er för XPS 15 9575 inkluderar Core i5-8305G och Core i7-8705G. Där steget från en i5-7300HQ till i7-7700HQ kan föra med sig en prestandaökning på runt 40% så är steget mellan i5-8305G till i7-8705G bara 5 - 10 procent. Om man väger in den massiva skillnaden i kostnad mellan i5- och i7-modellerna av XPS 15 9575 (11 000 kronor mot 19 000 kronor) så blir det uppenbart att man inte borde köpa Core i7-konfigurationen om prestanda-per-krona är prioriterat.
Istället har Dell rättfärdigat den stora skillnaden i pris med mer RAM och en panel med högre upplösning som i skrivande stund bara kommer tillsammans med Core i7 SKU:n. Den som kör tung multitasking, använder den tryckkänsliga skärmens stylus eller redigerar video kommer uppleva ett större värde av 16 GB RAM och ett alternativ för 4K UHD än vad dom flesta hemmaanvändare kommer göra. Men trots det så är vi besvikna på att dom aktuella Core i5-varianterna är begränsade till bara 8 GB RAM.
Utöver ovan nämnda skillnader så gäller våra existerande kommentarer om Core i5-versionen av XPS 15 9575. Kaby Lake G visar sig vara ett utmärkt alternativ till den allmänt förekommande kombinationen Core i7-7700HQ och GTX 1050 alternativt 1050 Ti som återfinns i dom flesta konkurrerande laptops. Dells omvandlingsbara är mer energieffektiv och håller sig svalare än dom nämnda systemen och är tystare än XPS 15 9560. Så länge man känner till den långa listan över nackdelar (se till höger) så kommer andra omvandlingsbara på 15 tum inte i närheten av vad XPS 15 9575 kan erbjuda, med ett anmärkningsvärt undantag i form av den kommande 2018 HP Spectre x360 15.
Du behöver inte spendera 19 000 kronor för alternativet med Core i7-8705G när modellen med Core i5-8705G bara är en aning långsammare för nästan 10 000 kronor mindre. Till och med den billigaste konfigurationen av XPS 15 9575 är nästan lika snabb som den dyraste XPS 15 9575 eller XPS 9560. Vi hoppas på att få se mer RAM och skärmalternativ för framtida modeller med Core i5 för att göra serien ännu mer tilltalande.
