Kantjes eraf gelopen. Dell heeft de Precision 3000 werkstations voor verassend weinig geld op de markt gebracht. We zijn benieuwd of we grote gebreken kunnen ontdekken.

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

Om de schermhelderheid te verlagen schakelen sommige laptops het backlight erg snel aan en uit. Dit gebeurt aan een dergelijk hoge frequentie dat het niet zichtbaar is voor het menselijk oog. Als de frequentie te laag is kunnen personen met gevoelige ogen geïrriteerd geraken, hoofdpijn krijgen en zelfs flickering waarnemen.

Screen flickering / PWM waargenomen

1064 Hz

90 % helderheid instelling

Het backlight van het scherm flikkert aan 1064 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 90 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 1064 Hz is redelijk hoog en de meeste mensen die gevoelig zijn aan flickering zouden dit dus niet mogen waarnemen of geïrriteerde ogen krijgen.

Ter vergelijking: 59 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 4287 (minimum: 43 - maximum: 142900) Hz waargenomen.

Responstijd Scherm

ℹ

De responstijden van het scherm tonen hoe snel het scherm in staat is om van één kleur naar de andere te veranderen. Trage responstijden kunnen aanleiding geven tot 'nabeelden' rond bewegende objecten of het scherm wazig maken (blur). Vooral spelers van snelle 3D-games hebben baat bij een scherm met snelle responstijden.

↔ Responstijd Zwart naar Wit
34.4 ms ... stijging ↗ en daling ↘ gecombineerd	↗ 17.2 ms stijging
34.4 ms ... stijging ↗ en daling ↘ gecombineerd	↘ 17.2 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games. Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 240 (maximum) ms. » 87 % van alle toestellen zijn beter. Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (27.1 ms) van alle geteste toestellen.
↔ Responstijd 50% Grijs naar 80% Grijs
48 ms ... stijging ↗ en daling ↘ gecombineerd	↗ 24.4 ms stijging
48 ms ... stijging ↗ en daling ↘ gecombineerd	↘ 23.6 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games. Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 74 % van alle toestellen zijn beter. Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (43.7 ms) van alle geteste toestellen.

Getest: Dell Precision 3520, testmodel geleverd door cyberport.de

De Precision 3520 heeft zeker sterke kanten. Ten eerste is er het heldere, levendige beeldscherm. Daarnaast is de batterijlevensduur goed voor een werkstation. De grotere 92 Wh batterij zal het nog langer volhouden. Het aanbod van aansluitingen is ook voldoende. De behuizing en invoerapparaten zijn goed genoeg voor een werkstation, maar ook niet perfect.

Helaas stelt de Precision teleur op het belangrijkste vlak voor werkstations: prestaties en geluidsproductie. De beperking tot een 35 Watt TDP processor is al ongebruikelijk - een sterker koelsysteem voor een krachtigere CPU was waarschijnlijk te duur voor Dell. We vragen ons af of kiezen voor een standaard langzamere CPU wellicht een betere keuze was geweest. Onze tests tonen namelijk aan dat de CPU prestaties nogal fluctueren, hoewel dit met firmware updates verbeterd kan worden. Dit geldt helaas ook voor de ventilator, die regelmatig draait wanneer er weinig belasting is. Na de benchmarks duurde het een lange tijd voordat het apparaat weer stil was. Tenslotte produceert de 3520 een vervelend zoemend geluid.

De Precision 3520 is een degelijk werkstation - maar zou een aantal verbeteringen goed kunnen gebruiken.

Alles bij elkaar kunnen we concluderen dat de Precision 3520 zeker potentie heeft. De notebook is behoorlijk krachtig en biedt een relatief goede prijs/prestaties verhouding. Immers, werkstations zitten meestal in hoge prijsklassen. Dell moet het apparaat heroverwegen en zich buigen over de ventilator en prestaties. Zodra deze inhaalslag is gemaakt kan de 3520 zeker een aanbeveling krijgen van ons.
