FPS Stability: Average Numbers vs Real Experience
Snapdragon 8 Gen 5 FPS Behavior
- FPS remains consistent during long sessions
- Less fluctuation when the phone heats up
- Better for competitive games where timing matters
Dimensity 9400 FPS Behavior
- Very high FPS at the start
- Minor dips after extended gameplay in poorly cooled phones
- Still smooth, but not always as stable as Snapdragon under stress
Important takeaway:
High peak FPS looks good in benchmarks, but stable FPS feels better in real gameplay.
Thermal Performance: Heat Makes or Breaks Gaming
Snapdragon 8 Gen 5 Thermal Control
- Gradual temperature rise
- Better thermal balancing
- Less aggressive throttling
Phones using this chipset usually stay comfortable to hold during long gaming sessions.
Dimensity 9400 Thermal Control
- Warms up faster under heavy load
