RTX 3090 Ti Benchmarks: Full Gaming & Synthetic Performance Overview
The RTX 3090 Ti sits at the pinnacle of Ampere-class GPUs, offering up to 20% faster speeds than the RTX 3090 in 4K scenarios. Let's break down exactly how it performs in games and benchmark suites across resolutions.
🎮 Real-World Gaming Performance
Native Raster & 1440p Focus
-
At 1440p, the RTX 3090 Ti averages around 8% higher FPS than the RTX 3090, delivering ~10% faster 1% low minimums across titles like Horizon Zero Dawn, Death Stranding, and others. Average FPS ranges from ~120 to 140 FPS in modern AAA games.
-
In titles like Rainbow Six Siege, 1440p benchmarks reach up to 360 FPS, highlighting its potential for ultra‑high refresh scenarios.
4K Realism Gaming
-
At 4K Ultra, RTX 3090 Ti delivers average FPS improvements of ~20% over RTX 3090, with results often landing 110–130 FPS in demanding titles such as Horizon Zero Dawn and Death Stranding.
-
Synthetic comparisons confirm 11% uplift over RTX 3090 in long-run FPS suite tests across numerous titles.
🌐 Synthetic & Compute Workloads
-
In 3DMark benchmarks like Fire Strike and Time Spy, RTX 3090 Ti outpaces the RTX 3090 by approximately 11%, positioning it just behind RTX 4090 in Ampere ranking.
-
AI-focused evaluation, like TensorFlow ResNet tests, place it around 20% faster than 2080 Ti and 6900 XT, offering significant compute headroom for creators.
🔧 Ray Tracing & DLSS Upscaling Performance
-
Users on Reddit report that Metro Exodus Enhanced Edition gives a ~17% advantage to the 3090 Ti over the non‑Ti model at 4K with RT enabled.
-
Even so, review commentary emphasizes that performance uplift is often modest, largely due to shared architecture and marginal clock gains over RTX 3090.
🧾 Summary Table
| Scenario | RTX 3090 Ti Performance | Relative Uplift |
|---|---|---|
| 1440p gaming suite average | ~120–140 FPS | ~8–10% faster vs RTX 3090 |
| 4K gaming average | ~110–130 FPS | ~20% faster |
| Rainbow Six Siege (1440p) | ~360 FPS | Highlights top-tier headroom |
| Ray traced 4K w/ DLSS | ~17% better than RTX 3090 | Improved frame pacing |
| Synthetic (3DMark suite) | ~11% faster overall | Leading Ampere-tier results |
| AI / TensorFlow benchmarks | ~20% faster vs RX 6900 XT | Best-in-class compute |
🗣️ Community & Expert Insight
-
From Reddit:
“Still… RTX 3090 Ti is clearly fastest consumer GPU money can buy… Metro Exodus Enhanced Edition puts it ~17% ahead over non‑Ti at 4K.”.
-
PCWorld notes that in benchmarks such as Cyberpunk 2077, 3090 Ti averages near 100 FPS at 1440p, closely matching RTX 4070 Ti in many cases—making purchasers question whether the Ti spend is justified.
🛠️ Efficiency & Platform Considerations
-
With a TGP of ~450W, RTX 3090 Ti demands robust power delivery and cooling, though raw performance justifies the size in most enthusiast setups.
-
Average FPS improvements are diminishing at lower resolution (1080p), where CPU bottlenecks limit scaling—effects seen in Far Cry 6, Horizon Zero Dawn, and others.
🎯 Conclusion
The RTX 3090 Ti remains a powerful GPU for 4K enthusiasts or creative pros needing both raw gaming speed and compute performance. Gains over the RTX 3090 average ~8–11% in raster gaming and reach ~20% in 4K workloads, while synthetic benchmarks and AI tests show meaningful headroom.
However, if you already own a 3090 or equivalent Ampere card and focus mainly on 1440p or DLSS-enhanced titles, the performance uplift may not justify retail pricing in 2025.
