The benchmark performance of HTC Desire 620G is not much different from any other phone with Mediatek 6592 chipset. Although it kind of under performed for some reason as you can see in the Antutu score below. Usually phones with same chipset score around 25,000 points but Desire 620G only managed to get around 23,000 points same as HTC Desire 616 but that one was under clocked to 1.4 GHz while Desire 620G has 1.7 GHz. Maybe just 1GB of RAM is the reason of that. And this lack of performance is kind of visible in the phones UI it sometimes stutter or even slows down or does not respond for a second or so.
