8. The difference between Qualcomm snapdragon 820 and 810

1, GPU

CPU is the computing power of the processor. The new customized kryo architecture (named kryo architecture, which is based on armv8 instruction set, supports 64 bit computing and up to 3GHz main frequency) is adopted by Qualcomm 820, which is different from the arm public architecture of Qualcomm 810. The main frequency reaches 2.2GHz, 14 bit spectrum image processor and heterogeneous signal processor are added for the first time
GPU is the graphics performance, which is equivalent to the independent graphics card of the computer. It is mainly related to playing large-scale games and application display. The stronger the performance, the better the graphics performance. With a new generation of Adreno 530 core built in, the graphics performance of Qualcomm 820 is about 40% higher than that of Adreno 430, and the power consumption is reced by 40%

2. Process comparison

the new Qualcomm 820 adopts the latest 14nm process, which is much higher than that of the 20nm Qualcomm 810. The more accurate the numerical value is, the more precise the internal part is, and the lower the power consumption will be. In terms of technology, the Qualcomm 820 is undoubtedly a more advanced generation

3. Network baseband comparison
in terms of mobile network support, Qualcomm 810 integrates 4G LTE advanced world mode modem and supports LTE FDD, LTE TDD, WCDMA (dc-hsupa), CDMA1X, EV-DO version b, TD-SCDMA and GSM / edge. 4G LTE advanced CAT6 speed up to 300 Mbps, LTE FDD and LTE TDD support carrier aggregation up to 3x20 MHz, generation 4 integrated LTE modem, and support qcomm rf360, LTE broadcast and LTE multi-mode al card al standby (DSDS and dsda)<
