Képernyő villogása / PWM (impulzusszélesség-moduláció)
Képernyő villogása / PWM észlelve | 1064 Hz | ≤ 90 % fényerő beállítása | |
The display backlight flickers at 1064 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1064 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. |

Kontra
A Precision 3520-nak egyértelműen vannak erényei. Először is a kijelző, amely élénk színekkel és remek fényerővel kényeztet minket. A telep üzemideje is elég jó egy munkaállomáshoz képest, és a nagyobb, 92 Wh-ás opcióval valószínűleg egyenesen kiváló lesz. A fizikai csatlakozók száma elégséges. A ház, és beviteli eszközök ugyan nem tökéletesek, de egy üzleti gépnek megfelelnek.
Sajnos a Precision pont a munkaállomások legfontosabb képességeiben botladozik: teljesítmény és zajszint. A 35 wattra korlátozott TDP már önmagában is furcsa - a Dell egy jobb hűtési rendszert pakolhatott volna a gépbe, bár az már feltornázta volna az árat. Talán egy névleg gyengébb CPU jobb megoldás lehetett volna. Terhelési tesztünkből az is kiderült, hogy a teljesítmény erősen ugrál komolyabb igénybevétel esetén, valószínűleg azért, mert a firmware finomhangolásra szorul. Ez sajnos a ventilátorvezérlésre is igaz: a ventilátor terheletlenül is sokszor felpörög. A benchmarkok után pedig sokáig nem áll le. Emellett a 3520-nál még tekercszajt is tapasztaltunk.
A Precision 3520 elég jó munkaállomás, de lenne mit csiszolni rajta.
Összességében, a Precision 3520-ban látjuk a potenciált. A notebook elég erős, és az ár/érték aránya is jó. Végül is, a munkaállomások általában elég drágák. Ha a Dellnek sikerül a ventilátorvezérlést és a teljesítményt optimalizálni, úgy a 3520 egy határozottan ajánlott vétel lehet majd.
