HTC Desire comes with Mediatek 6752 which consists of octa-core Cortex A53 processors clocked at 1.7GHz and the reason why it is currently the king in lower mid-range chip-sets in terms of performance, Mali T760 GPU. So obviously it’s benchmark performance would be good too.
Gaming on this phone is blissful. There’s no game in the Google Play Store that this phone currently can not play. It’s HD resolution also helps. Mediatek 6752 combined with HD display always produces good gaming performance. And it doesn’t even get that much hot. During my gameplay of games like Asphalt 8 and GTA San Andreas on high and maximum settings, it not even once touched 40° celsius mark.
