A Snapdragon 801, the chip used on some of 2014's flagship devices like the HTC One (M8) and the Samsung Galaxy S5, runs hotter than the new 64-bit Snapdragon 810. The skin temperature of a Snapdragon 801 powering a commercial handset running racing game Asphalt 8 ran up against the high end of that range twenty minutes into game play. On the other hand, a Snapdragon 810 playing the same game for the same amount of time on a non-commercial handset showed a skin temp 5 degrees lower.
The difference is even more pronounced when measuring the temperature of both processors while capturing video on the respective handsets. A cooler running Snapdragon 810 means a better performing smartphone with a longer battery life. The chip will be used in most Android flagships this year including the HTC One (M9) and the LG G4. Despite talk about the chip overheating, other tests have shown it to be a cooler running component. That has been seconded by LG as the manufacturer calls it one of the coolest processors it has tested.
Snapdragon 810 proves to be cooler than the Snapdragon 801
