Helio X20 vs Snapdragon 810 Heat Comparisons Leaked

by Martin 1

MediaTek recently conducted an internal heat test to compare their newly unveiled Helio X20, the company’s first deca-core processor, against the Snapdragon 810 from Qualcomm and the results of those tests have been obtained and published by the folks at STJS Gadgets Portal.

The results revealed that the Snapdragon 810 would start off using its low-powered cores for a certain amount of time (15 minutes in the tests) then it would switch to its high-powered cores which would result in the device heating up. On the other hand, the Helio X20 would dynamically switch between and simultaneously use its low, medium, and high-powered cores depending on the current load and temperature.

The high-powered cores take some of the load off the medium-powered cores to keep the device cooler. Since the high-powered cores use only 2 cores then the overall heat of the device is lower.

Looking at the temperature graphics included in the documents, it’s obvious that the Snapdragon 810 runs significantly hotter than the Helio X20. The Snapdragon 810 runs more than 10 degrees hotter than the Helio X20 with a peak load temperature of 45 degrees before switching to its high-powered cores while the Helio X20 only reaches a peak load temperature of around 33 degrees before it starts cooling down by switching to its high-powered cores.

Notably, the Snapdragon 810 has been recently known to overheat in some devices.

Based on these results, it looks like the Helio X20 has a big advantage over the Snapdragon 810 when it comes to temperature but it also must be noted that the authenticity of these leaked documents are not assured and even if they are authentic, they are internal tests by MediaTek which could possibly be swayed to favor the Helio X20. We’ll have to wait for real world tests conducted on real retail devices to ascertain the temperature performance of the Helio X20.
