Performance in games and everyday tasks
One of the biggest questions when choosing a smartphone is its ability to handle gaming and multitasking, so let's take a look at how the Snapdragon 662 in Redmi 9T performs in real-world settings.
In synthetic tests (like AnTuTu 9), the chip scores about 180,000 to 200,000, which is the average for the budget segment. By comparison, the Snapdragon 480 (newer but weaker in games) gives ~250,000, and MediaTek’s Helio G80 scores ~200 thousand.
The game is as follows:
- 🎮 PUBG Mobile: Medium settings (30) FPS), graph can be raised to HD friezy.
- 🏎️ Asphalt 9: Medium graphics, rare slowdowns in dynamic scenes.
- 🗡️ Genshin Impact: Low Settings (20–30) FPS), playable.
- 🃏 Free Fire: High settings (40–50) FPS), no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no-no.
In everyday tasks (social networks, instant messengers, 1080p video), the Redmi 9T shows itself stable. The only caveat is that when you multitask actively (10+ open applications), there can be small delays when switching, this is due not so much to the processor as to the amount of RAM (4 GB in the basic version).
| Test | The result | Comparison with competitors |
|---|---|---|
| AnTuTu 9 | ~190 000 | Below the Helio G85 (~210,000), but above the Snapdragon 460 (~160,000). |
| GeekBench 5 (Single-Core) | ~310 | Comparable to the Kirin 710 (~320), but worse than the Dimensity 700 (~500). |
| GeekBench 5 (Multi-Core) | ~1 350 | Loses the Helio G90T (~1,800), but overtakes the Snapdragon 450 (~1,100). |
| 3DMark Wild Life | ~700 | The Adreno 618 (~900) is inferior, but the Mali-G52 (~600) is better. |
