Dell Latitude 7390 2-in-1 (i7-8650U, FHD) Convertible rövid értékelés

Name: Dell Latitude 7390 2-in-1
Brand: Dell

Professzionális átalakítható… Sok dolog tetszhet a Latitude 7390 2-in-1-ben, például a négymagos Core i7-8650U CPU, az NVMe SSD, a kompakt, strapabíró ház, vagy a dupla háttértár lehetősége. Nem mentes viszont a hátrányoktól sem, és elég drága is.

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
30.4 ms ... rise ↗ and fall ↘ combined	↗ 16.4 ms rise
30.4 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 0.8 (minimum) to 240 (maximum) ms. » 76 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (24.6 ms).
↔ Response Time 50% Grey to 80% Grey
48.8 ms ... rise ↗ and fall ↘ combined	↗ 23.6 ms rise
48.8 ms ... rise ↗ and fall ↘ combined	↘ 25.2 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. » 80 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (39.2 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 not detected

In comparison: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18037 (minimum: 5 - maximum: 2500000) Hz was measured.

Pro

+ strapabíró, vonzó kivitel

+ nagyon jó beviteli eszközök

+ gyors rendszer

+ viszonylag kényelmes karbantartás

+ remek csatlakozóválaszték

+ kis méret

+ két háttértár is kerülhet bele (2 x M.2 SSD)

Kontra

- a Core i7 nem sok előnnyel jár az egymagos teljesítményt nem számítva

- a gép a vastagabb kijelzőfedél miatt eléggé fejnehéz

- erősen tükröződő kijelző

- középszerű színlefedettség és -hűség

- méretéhez képest kissé nehéz

- az átalakítható design előnyei kérdésesek az átlagos üzleti munkakörnyezetben

The Dell Latitude 7390 2-in-1. Test model provided by Dell US

A Latitude 7390 2-in-1 egy jól összerakott, strapabíró, vonzó gép, remek beviteli eszközökkel, és gyors rendszerrel. Ezen felül kiváló csatlakozókínálattal, kényelmes karbantartással és kategóriájában kompaktnak számító kivitellel örvendeztetett meg minket. A dupla háttértáröböl különösen lenyűgöző, amelyet az üres WWAN hely tesz lehetővé, ahová egy második M.2/NVMe 2230 SSD-t is be tudunk pakolni. Ugyan a CPU teljesítménye is kicsivel nagyobb, mint az előző generáció hasonló gépeinek, a tesztelésre kapott Core i7-es konfigurációt nem látjuk indokoltnak. Amennyiben nem egyszálas alkalmazások jelentik majd a fő feladatot, úgy az olcsóbb, Core i5-ös konfigurációt ajánljuk.

A Latitude 7390 2-in-1 egy jól összerakott, strapabíró, vonzó gép, remek beviteli eszközökkel, és gyors rendszerrel. Ugyanakkor megvannak a maga hiányosságai, és határozottan nem kis befektetés - ezért azt javasoljuk, hogy mielőtt lecsapnánk rá, mérjük fel alaposan a kínálatot.

Egyébiránt a 7390 2-in-1 mellett több kérdőjel is lebeg. Kizárólag nem matt érintőkijelzőkkel kapható, és egyikük sem túl lenyűgöző színlefedettséggel bír—legalábbis nem a kategória olyan csúcsgépeihez képest, mint a ThinkPad X1 Carbon. Az NVMe SSD nem igazán összemérhető a többi, például a Samsung által gyártott hasonló meghajtókkal. A gép a méretéhez képest nehéznek tűnik, és a vastagabb, és viszonylag súlyos kijelzőfedélnek köszönhetően nem ül annyira stabilan az ember ölében, mint az ideális lenne. Végül pedig még mindig adott a kérdés, hogy vajon az üzleti életben a legtöbbeknek valóban szüksége van-e az átalakítható funkcióra, amelyet ezek a Yoga-stílusú gépek nyújtanak. A Dell-nek már van egy teljesen használható, extrém jól kiegyensúlyozott ajánlata az alap Latitude 7380 képében (és, bár még nem teszteltük, de valószínűleg a 7390 sem lesz rosszabb)—amelyet tükröződésmentes kijelzővel is lehet kapni, könnyebb, és összességében stabilabbnak érződik minden vízszintes felületen.

További gépek, amelyeket érdemes megnézni (a hagyományos Latitude 7380/7390-en kívül): a kitűnő ThinkPad X1 Carbon 2018 és az Asus Zenbook 13 UX331UA. 2109 dolláros (jelen konfiguráció) árával a Latitude 7390 2-in-1 határozottan nem kis befektetés - ezért azt javasoljuk, hogy mielőtt lecsapnánk rá, mérjük fel alaposan a kínálatot.
