Qualcomm is all about heat testing lately it seems. The company has decided to show how much cooler their yet unreleased Snapdragon 815 runs compared to the Snapdragon 801 and Snapdragon 810. As you already probably know by now, some manufacturers have said that Qualcomm’s Snapdragon 810 SoC is getting really hot after some intensive use. HTC’s One (M9) device is powered by that chip, and the handset got extremely hot when someone tried to run AnTuTu benchmarks on it during MWC. That device was rockin’ an unfinalized version of the OS, and it’s probably not the issue any longer. One thing is for sure though, the Snapdragon 810 is getting hotter than it should, and Qualcomm obviously acknowledged that considering they decided to showcase how cooler the Snapdragon 815 will be.
That being said, the company decided to compare another pair of chips in this test, the Snapdragon 615 and the yet unreleased Snapdragon 620. The Snapdragon 615 is a well-known 64-bit octa-core processor which is already powering a lot of handsets all around the world. Qualcomm didn’t use Asphalt 8 to compared the two chips this time around though, they decided to go with Mortal Combat 5. This game is even more demanding that the Asphalt 8, so this seems a bit odd. Either way, the game run great on a device which sports a 4.7-inch (1280 x 720) IPS display with 1.5GB of RAM without cellular antenna or radio. The game ran on both chipsets for 20 minutes before Qualcomm decided to measure their temperature.
The Snapdragon 620 performed better in this test, this chip hit 107.6 degrees Fahrenheit (42 degrees celsius), which was cooler than 114.8 degrees Fahrenheit (48 degrees celsius) they measured on the device which is powered by the Snapdragon 615. You can expect somewhat higher temperatures which have a cellular antenna and a radio. The test also showed that the Snapdragon 620 cools down constantly after the gaming is over, while the Snapdragon 615 got cooler for the first 15 minutes and then the temperature started acting up. By doing these tests, the company is obviously trying to prove that they’ve solved the heat issues their mid-range and high-end chips had.
