Business Kaby Lake Windows Laptop / Notebook Ultrabook

Okosabb üzleti? Az egyik legjobb üzleti ultrabook még erősebb lett egy 8. generációs Core i7-8650U CPU és egy NVMe SSD beépítésével—valamint egy elég jó tükröződésmentes érintőkijelzővel. Megérik ezek az extrák a magasabb árat? Cikkünkből kiderül.

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
30.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 11.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (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 (25.7 ms).
       Response Time 50% Grey to 80% Grey
36.8 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 18.8 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. » 30 % 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9152 (minimum: 43 - maximum: 142900) Hz was measured.

Pro

+ hibátlan magnézium kivitel
+ könnyű és viszonylag kis méretű
+ tényleg tükröződésmentes érintőkijelző
+ átgondolt biztonsági funkciók
+ remek csatlakozókínálat, Thunderbolt 3 is
+ könnyű karbantartás az alsó burkolat eltávolításával
+ kitűnő billentyűzet

Kontra

- nem nyitható egy kézzel
- a Core i7 frissítés haszna megkérdőjelezhető
- az ujjlenyomat olvasó kissé bizonytalanabb egyes modellekénél
- a zsanér design miatt nagy nyitási szögnél a fedél felemeli az alapot
- az alapjárati felületi hőmérséklet kényelmetlen lehet a gépet ölben tartva

In review: Dell Latitude 7390. Test model provided by Dell US

A Latitude 7390 múlt havi értékeléséhez képest most rövidebb lett a panaszlistánk, részben a mostani gép eltérő konfigurációjának köszönhetően, és részben azért, mert egyes problémák valószínűleg az adott példány egyedi hibái voltak. A Core i7 frissítés határozott teljesítménytöbbletet jelent, elsősorban tartós terhelés esetén, nem csak nagyobb, de egyenletesebb sebességet produkálva. A legtöbb felhasználó számára azonban a Core i5 több mint elegendő, és az ára is feléje billentheti a mérleget. Az NVMe SSD esetében is nagyrészt ugyanez a helyzet (a múlt havi Latitude 7390 M.2 SATA SSD-jével összevetve) amely gyorsabb, de jobban melegszik és drágább. A legnagyobb meglepetés azonban a tükröződésmentes érintőkijelző: ez esetben  valóban tükröződésmentes; negatívuma pedig gyakorlatilag nincs a korábban tesztelt hagyományos (nem érintős) panelhez képest.

Valóban drága, de kevés annyira sok téren lenyűgöző laptop van ebben a kategóriában, mint a Latitude 7390.

Az előnyök korábbi listája itt is megállja helyét. A 7390 kivitelezése hibátlan, a felépítése strapabíró, miközben meglehetősen kis méretű és könnyű. A karbantartása könnyű, ehhez az alsó fedelet kell leszerelni. A csatlakozókínálata és biztonsági funkcióival a sokat utazó üzleti ügyfelek, és a céges IT-részlegek is elégedettek lesznek. A billentyűzet és touchpad összességében nagyon jó, a kijelzőpanel pedig kifejezetten vonzó, amelyet az érintőképesség miatti változások sem rontottak le. Végül, a készülék legtöbbször szinte néma, az üzemideje pedig kellően hosszú. A 3 éves onsite garanciával megfejelve ez egy nagyon erős versenyző az üzleti szegmensben.

A 2197 dolláros ár határozottan sok,  de kevés annyira sok téren lenyűgöző laptop van ebben a kategóriában, mint a Latitude 7390. A Lenovo X1 Carbon és a HP EliteBook Folio 1040 G4 lehetnek a fő riválisai, de ezek közül a gépek közül tulajdonképpen egyikkel sem járhatunk rosszul.
