Famiglia HTC Desire (Z e HD): Processori a confronto

Come abbiamo più volte riportato, nei giorni scorsi HTC ha allargato la famiglia Desire con due nuovi terminali Google Android di fascia alta, stiamo parlando del Desire HD e del Desire Z.

I due nuovi device si presentano con caratteristiche tecniche diverse, la differenza sostanziale, a parte l’estetica e la presenza della tastiera fisica nel Desire Z, riguarda la scelta del processore, Snapdragon MSM8255 da 1GHz per il Desire HD, Snapdragon MSM7230 da 800 MHz per il Desire Z ed infine Snapdragon QSD8250 per il vecchio Desire.
