The new Snapdragon 820’s features include new 14-nanometer architecture, an efficient quad-core setup, a brand-new GPU, and 600 Mbps Cat. 13 baseband technology. A Weibo user had shared details on the Snapdragon 820’s actual performance, and it does seem like a credible leak – Samsung’s purported 2016 flagship, the Galaxy S7, is said to come with a Snapdragon chipset under the hood, and the score supposedly matches up with tests done on this upcoming device.
The Snapdragon 820 was compared to the existing Snapdragon 810, but in this comparison, two versions of the newer processor were used – an early prototype and the current version. In the leaked AnTuTu benchmark test, the old Snapdragon 810 was able to reach 63,378 points, the early Snapdragon 820 prototype hit 66,715, while the newer version reached an amazing 70,661 points. That makes it, in theory, 5 percent and 11 percent more powerful than the Snapdragon 820 prototype and the Snapdragon 810 respectively.
Basing on what we’ve learned from the leak, the use of new and independent architecture on the Qualcomm Snapdragon 820 is the driving factor behind its improved performance. By contrast, the Snapdragon 810 was notorious for overheating and, in general, underperforming; this, if you remember, had forced Samsung to go with an Exynos processor for all versions of its Galaxy S6. So in a processor space where eight-cores are becoming more and more prevalent, it seems as if Qualcomm would rather go back to quad-cores for its latest chip.
