Snapdragon 860 have Adreno 640 Snapdragon 7s gen 2 have Adreno 710 Adreno 640 have 10-14% higher gpu benchmark score Hovewer in games it depends on game. In one game Adreno 710 will get more FPS in other one Adreno 640 get more FPS. Advantage of Snapdragon 7s gen2 are lower temperatures, lower power consumption, longer support. Performance in both is almost the same. But my sugestion is if someone can pay little more then he should get Snapdragon 7 Plus gen 2 instead of 7s gen 2. Snapdragon 7 Plus gen 2 is more powerfull than Snapdragon 888. And only have little smaller performance than Snapdragon 8 gen 1 and don't have overheating issues like them.
