RTX 3090 vs RX 7900 XTX: Which Should You Actually Buy?
Head-to-head: RTX 3090 vs RX 7900 XTX. Side-by-side specs, real-world performance, price-to-performance and a clear buy recommendation for 2026.
RTX 3090 vs RX 7900 XTX: the short version
Two strong options in the same gpu class, aimed at different buyers. Below is a clean side-by-side, the real performance gap, and a no-nonsense recommendation so you stop second-guessing and buy the one that fits your build and budget.
Side-by-side specs
| Spec | RTX 3090 | RX 7900 XTX | | --- | --- | --- | | Vendor | NVIDIA | AMD | | Tier | flagship | flagship | | Released | 2020 | 2022 | | VRAM | 24 GB GDDR6X | 24 GB GDDR6 | | Board power | 350 W | 355 W |
Real-world performance (estimated)
Estimated average FPS from a tuned config — your CPU, resolution and settings shift these, but the gap between the two holds:
| Model | 1080P Low | 1080P Med | 1080P High | 2K Med | 4K Med | | --- | --- | --- | --- | --- | --- | | RTX 3090 | ~246 | ~197 | ~154 | ~110 | ~53 | | RX 7900 XTX | ~303 | ~242 | ~189 | ~136 | ~65 |
Head-to-head: who wins what
- Performance: RTX 3090 and RX 7900 XTX trade blows by workload. RTX 3090 has the edge where its stronger 24 GB GDDR6X and 350 W of headroom matters; RX 7900 XTX wins the rest.
- Efficiency: RTX 3090 draws less power and is easier to cool and power.
- Value: Same-class rivals shift price constantly — check current street pricing and let the cheaper one at your target resolution decide value.
- Our pick: Buy RTX 3090 if you want the outright ceiling and can cool/power it. Buy RX 7900 XTX if you want lower power, lower cost, or a feature the other lacks. (Plan for ~355 W board power plus the rest of the system.)
Confirm headroom before you commit

Real-world verdict
Different generations, same 24 GB class. The RX 7900 XTX is faster in raster, far more efficient, and much cheaper (it launched at $999 versus the 3090's $1,499), making it the better pure gaming value. The RTX 3090's edge is compute: CUDA, and that 24 GB for AI / video / 3D workloads where NVIDIA's software stack dominates. Gaming only — take the XTX. If you actually use the VRAM for creation or local AI, the 3090 still earns its keep second-hand.
