There are some gaps, as follows
1. Different power consumption
Snapdragon 845 is a 10nm core, while 855 is a 7nm core, compared to 7nm power consumption is low, and it is more power-saving to do the same thing.
2. Different performance
中央处理器
Compared with the Snapdragon 845, the Snapdragon 855 not only upgrades the CPU architecture to the latest four generations, but also adds the new A76 large core and middle core, which significantly improves the performance of the A75 large core compared with the Snapdragon 845, while the four A55 small cores remain unchanged, and the CPU performance is expected to increase by 45%.
The big core can deal with tedious things, while the middle core can deal with ordinary information, and the small core is standby, better performance and more power saving. It's not that the bigger the core, the better the frequency. For example, Apple's A-series processor, four cores can top eight cores of the cpu. This kind of core allocation can improve work efficiency.
图形处理器
Snapdragon 855 compared to Snapdragon 450 GPU graphics core from Adreno 630 to Adreno 640, according to Qualcomm, GPU performance improved by 20%, the increase is relatively large.
艾尔
Al is artificial intelligence, the AI performance of the new generation of Snapdragon 855 is 3 times that of Snapdragon 845, and the performance has undoubtedly been greatly improved.
3. The network is different
The Snapdragon 845 only supports 4G networks, while the 855 integrates the X50 5G baseband, which supports 5G networks and is faster. Network this is very important, more than two years to enter the 5G era.
An 855 is better than an 845.
