The 64-bit capable Snapdragon 810 chipset has been anything but a positive story for Qualcomm. Rumors dating back from December argued that the Snapdragon 810 is plagued by overheating problems, and although Qualcomm was quick to deny such claims, the company did announce the loss of a major customer for this year. Interestingly, a few Qualcomm tests leaked online today, showing improved thermal efficiency in the upcoming Snapdragon 815 and Snapdragon 620 chips.
The Snapdragon 815, which is a currently unannounced chip, is said to be compared against both the Snapdragon 810 and the Snapdragon 801 on a test smartphone with a 5-inch fullHD display and 3GB of RAM. The source says that the devices ran Asphalt 8 Airborne for 30 minutes, with the surface temperature of the device constantly monitored.
The first documents show the Snapdragon 810 running at lower temperatures overall compared to the Snapdragon 801, but another set of documents published by the same source shows that the Snapdragon 810 is running at slightly higher temperatures. The second set of tests also features the Snapdragon 815, and its temperatures are lower than both the 801 and the 810. Given the inconsistency in these leaked test results, it's probably best to maintain a dose of skepticism regarding their validity.
A third set of leaked test results shows that the Snapdragon 620 has better thermal efficiency compared to the Snapdragon 615. Allegedly, Qualcomm benchmarked the chips on a test platform with a 4.7-inch HD display and 1.5GB of RAM. The test implied 20 minutes of Modern Combat 5, with the surface temperature of the smartphone recorded for the following 10 minutes as well.
