At present, foreign media anandtech has obtained the engineering tester for the Snapdragon 820. They have conducted a series of comprehensive performance tests on the Snapdragon 820, which is very close to the production version. However, the performance of Snapdragon 820 is not as strong as everyone expected. In many projects, the performance is even worse than Xiaolong 810.
The Snapdragon 820 adopts the self-developed Kryo architecture and uses the Samsung FF 14nm LPP process. It has two large cores with a 2.15GHz frequency, two 1.593GHz small cores, a large core level 2 cache, and a small core level 2 cache. 512KB, 32-bit dual-channel LPDDR4 1803MHz memory, bandwidth up to 28.8GB/s, GPU Adreno 530, frequency 624MHz.
In the browser running points, the Snapdragon 820 engineering machine and the Android machine all use the Chrome browser. In the browser running score, the Kraken 1.1 project scores worse than the Snapdragon 808 LG G4, and the browser Running in the iPhone 6s Plus was completely suppressed, but here we must explain that the iPhone's browser running points is Safari, there is a running bonus effect, but it is also leading too much.
In addition, the Basemark Snapdragon 820 2381 points also lost to the iPhone 6s Plus ( Apple A9 processor), because anandtech did not get the Huawei Mate 8 machine so there is no Kirin 950 running points, we use Huawei Mate 8 Basemark's running points resulted in more than 1900 points. In addition, PCMark did not log into the Apple Store. Therefore, there was no Apple A9 in the PCMark project. Xiaolong 820 suppressed the second Galaxy Note 5 700 points in this project.
In the GPU segment, GFXBench, under the ES3.1 Manhattan off-screen test, the Snapdragon 820 has 30 frames, which is twice that of the Galaxy Note 5. Since the iPhone does not support ES3.1, Apple does not appear in this project. . In the 3.0 screen in Manhattan, T-Rex 3.0 off screen, Snapdragon 820 took first place, while the second place is iPhone 6s Plus, a difference of 5 to 10 frames. In the non-off screen mode of GFXBench, Snapdragon 820 runs a 2K resolution, and its performance is not ideal.
But in the 3DMark test, Snapdragon 820 lost to iPhone 6s Plus, Galaxy Note 5 in Ice Storm Unlimited's total score, and even Xiaomi Note Pro was ahead of Snapdragon 820, passing 3DMark's CPU score and GPU's score. It can be seen that the Snapdragon 820 is on an equal footing with the iPhone 6s Plus on the GPU score, but the CPU has lost significantly to the Xiaolong Note Pro of the Suilong 810 and the Galaxy Note 5 of the Exynos 7420, resulting in an unsatisfactory total score.
to sum up
From the test results, the GPU Adreno 530 of the Snapdragon 820 is as strong as the rumors, and in the CPU part, Qualcomm’s own Kryo architecture has been dragging the back of the entire Snapdragon 820. The performance is even worse than the Snapdragon 810. Lagging behind Apple A9, simply speaking, the total score of Xiaolong 820 is still not as good as Apple A9.
