Snapdragon 810 processor: cooler than ever

Whether you’ve been using a Qualcomm Snapdragon powered mobile device since our earliest days and thinking about an upgrade, or wondering what all the commotion is about, I’m pleased to tell you that one of the best has gotten even better. Not only is the Snapdragon 810 processor designed to deliver more performance and better experiences, but it’s also engineered to use less power and remain cooler. 

For months we’ve talked about improved Snapdragon 810 performance, including the new Qualcomm Adreno 430 GPU with 30 percent more performance and 20 percent lower power than previous generation. But now we get to show you that devices with Snapdragon 810 can also be cooler. Don’t take my word for it, let’s take a look at the results.

Bear with me for some background and geek speak to explain.

  • The “skin temperature” is the temperature at the surface of the smartphone.
  • Room temperature is typically 25°C. 
  • Simple tasks and usage, like making phone calls and taking pictures, will result in a skin temperature of about 30-35°C. 
  • The most demanding scenarios, like gaming and 4K video capture, will have a skin temperature range of approximately 35-45°C.
  • Most phones will set a skin temperature limit of ~45°C, and will throttle performance so as not to exceed this temperature.

The charts below show Qualcomm Technologies' test of skin temperature over time of two Snapdragon based smartphones of a comparable size. “Device A” (left) was measured off a commercial smartphone with Snapdragon 801, while Device B” (right) was measured on a pre-commercial smartphone with Snapdragon 810. Each is playing a racing game, Gameloft’s Asphalt 8, smoothly at 30FPS. Notice that after about 20 minutes of gaming, the Snapdragon 801 has hit the thermal ceiling. At over 30 minutes of gaming, the Snapdragon 810 smartphone still has additional headroom.

The story is the same with 4K video capture. After about 5 minutes of continuous recording, the Snapdragon 801 smartphone approaches the skin temperature threshold, while the Snapdragon 810 smartphone is well below the limit.

Why should you care? A cooler smartphone means a better performing smartphone. When a device hits the thermal threshold, it will throttle performance to cool down. If you want the best of both worlds, higher performance with lower power, then you want a Snapdragon 810 powered smartphone. 

Check out the “cool” new Snapdragon 810 smartphones already announced, like the LG G Flex2 and Xiaomi Mi Note Pro, stay tuned for the upcoming products from Motorola, Sony, HTC, OPPO, and Microsoft.
