Recensione breve del Subnotebook HP EliteBook 820 G2

Aggiornamento a Broadwell.L'EliteBook 820 G2 è un notebook business da 12.5 pollici. Nel complesso ci ha fatto una buona impressione e non si deve nascondere dalla concorrenza. Comunque, non è esattamente economico dato che costa poco meno di 2000 Euro (~$2253).

The HP EliteBook 820 G2. Test model courtesy of HP Germany.

L'HP EliteBook 820 G2 è l'aggiornamento Broadwell del modello 820 G1. Solo i componenti interni sono cambiati dato che l'esterno è rimasto identico. La nuova combinazione CPU-GPU garantisce un discreto aumento delle prestazioni. Inoltre, c'è un case di fascia alta, l'ottima e sofisticata manutenibilità e ottimi dispositivi di input. Il dispositivo non scalda molto e funziona silenziosamente. Sfortunatamente, la ventola genera un rumore di fondo abbastanza fastidioso. Il modem LTE permette l'accesso ad internet anche in mobilità. Ci è piaciuto anche lo schermo IPS, luminoso e contrastato. Nel complesso si applica lo stesso verdetto del predecessore Haswell:

Ha tutte le carte in regola per essere un ottimo dispositivo portatile professionale
