Qualcomm Snapdragon 810’s Bad Thermal Rep Put To Rest

February 15, 2015 - Written By Christopher Dal Porto

The latest next generation chip from Qualcomm inbound to power the flagships of 2015 is their fastest mobile processor to date. This 64-bit architecture quad core processor with an updated Adreno 430 GPU promises to be the powerhouse for the incoming phones with 2560×1440 resolution displays and 4K resolution video recording while also featuring up to 20 percent lower power consumption. While this high end processor looks great on paper, there have been recent concerns raised regarding its thermal performance. Comments of poor heat dissipation brought attention onto the manufacturer, shortly before Samsung was rumored to decide on using their own Exynos processor in the Galaxy S6 rather than the Snapdragon 810.

Luckily for us, STJS Gadgets portal was able to run in house tests on the Snapdragon 810 processor and were able to do a thermal comparison with the Snapdragon 801. While both mobile processors are quad core, the newer snapdragon 810 boasts up to 30 percent more performance making it hard to believe it could run at a lower operating temperature. The testers at STJS Gadgets Portal put phones powered by both processors to various tasks involving high performance gaming and 4K resolution video recording. Recorded temperatures were measured from the surface of the phones as skin temperature, so the chips themselves were likely to be slightly warmer. Remarkably, the Snapdragon 810 in both tests proved it was superior with operating skin temperatures of approximately 12 to 15 percent lower than the Snapdragon 801. While powering through the gaming tests the Snapdragon 810 reached peak skin temperatures of 40 degrees Celsius while the older Snapdragon 801 reached a higher temperature of 45 degrees Celsius. During the second test of 4K resolution video recording the Snapdragon 810 hit peak temperatures of 35 degrees Celsius while again the Snapdragon 801 lost hitting a much higher 43 degrees Celsius.

With recent reports of possible heat issues revolving around the Snapdragon 810, these test results certainly raise questions as to where this all began. LG openly supported the Snapdragon 810 stating there were no heat dissipation issues from the start, and still plan to use it to power their upcoming LG G Flex 2 curved smartphone. The fact that the Snapdragon 810 was able to run much cooler also gives it a performance advantage over the Snapdragon 801 on top of its improved specs, because less heat means less thermal throttling. Phones are designed to read their processing temperatures, and at a certain level begin to lower processing performance. All of this indicates that upcoming flagships phones coming this year will be much faster with lower temperatures and better battery life.
