Snapdragon 8 series and 7 series are the two mobile processor series launched by Qualcomm, and the differences between them mainly include the following aspects:
Process technology: The Snapdragon 8 series uses a 7nm process, while the 7 series uses an 8nm or 11nm process. The improvement of the manufacturing process can improve the performance and energy efficiency of the chip.
Number of CPU and GPU cores: The Snapdragon 8 series uses more CPU and GPU cores and is more powerful than the 7 Series. For example, the high-end models in the Snapdragon 8 Series can carry up to three CPU clusters and one GPU cluster, while the 7 Series has a maximum of two CPU clusters and one GPU cluster.
5G network support: The Snapdragon 8 Series chips integrate more advanced 5G modems to support higher 5G network rates and more 5G frequency bands, while the 7 Series 5G network support is relatively limited.
AI performance: The Snapdragon 8 Series AI performance is more powerful than the 7 series, its Hexagon 780 AI accelerator AI performance can reach 15 TOPS, while the 7 Series AI performance is only 2.7 TOPS.
In general, the Snapdragon 8 series is better in terms of performance and features than the 7 series, but the corresponding price is also higher. Therefore, the choice of which processor needs to be based on their needs and budget to make a comprehensive consideration.
The difference is different positioning.
Snapdragon 8 is Qualcomm's high-end series, and Snapdragon 7 is the mid-range series.

If it is the same generation, the Snapdragon 7 Snapdragon 8 process may be the same, but the material selection must be different. Some of the frequency parameters of Snapdragon 8 are definitely much stronger than Snapdragon 7, otherwise why should he sell it more expensive?
Snapdragon's 7 series chip belongs to the high-end SOC, while the Snapdragon 8 series chip is the flagship standard.
Snapdragon is the name of Qualcomm's processor family platform for mobile devices. Snapdragon mobile platforms, processors, modems and chipsets use a new architecture for artificial intelligence and immersive experiences to meet the intelligence, power, connectivity and other performance required by the next generation of mobile computing.
The 8-series is a high-end chip, and the 7-series is a mid-range chip.
