At about the same temperature, somewhere between 20 and 25 degrees Celsius, the Snapdragon 810 and the Helio X20 began. Both chips warmed up to approximately 30 degrees Celsius at the 10 minute mark, but the Snapdragon 810 seemed to be a little cooler.
The Snapdragon 810 is assumed to have been using its four 1.5GHz clocked ARM Cortex-A53 while browsing the internet. The Helio X20 depended on its four ARM Cortex-A53 cores clocked at 1.4GHz, as per the leaked slides, while also shifting to its four Cortex-A53 cores clocked at 2GHz when heavier sites needed more processing power.
In comparison, depending on the load on the processor and the heat produced in the process, the MediaTek X20 can continuously switch from low-powered to medium, medium to high-powered processor cores, and inversely.
A high-end graphics video game, for example, could cause the processor chipset to overheat as it reaches 38 degrees Celsius, which is the temperature threshold for mid-power cores. The chipset distributes the energy right at this point to high-power cores that use only two cores to mitigate the excess heat produced.
It’d have been nice to have an aspect ratio chart to go along with the dissipated heat chart, since if the Helio X20 held a lower temperature by reducing processing power, it would not be much of an improvement.
At peak load, Qualcomm’s Snapdragon 810 crosses the temperature level of 45 degrees Celsius, before dropping to 40 degrees Celsius shortly after the transition from low-powered to high-powered processor cores.
