AMD Radeon RX 6900 XT vs NVIDIA GeForce RTX 3090
The AMD Radeon RX 6900 XT and NVIDIA GeForce RTX 3090 sit within a few percent of each other on our index. Treat them as equivalent in raw performance and decide on price, power draw and — for graphics cards — video memory instead.
| Specification | AMD Radeon RX 6900 XT | NVIDIA GeForce RTX 3090 |
|---|---|---|
| Manufacturer | AMD | NVIDIA |
| Architecture | RDNA 2 | Ampere |
| Relative performance index | 170 | 180 (better) |
| Video memory | 16 GB | 24 GB (better) |
| Memory type | GDDR6 | GDDR6X |
| Memory bus | 256-bit | 384-bit (better) |
| Release year | 2020 | 2020 |
| Board power | 300 W (better) | 350 W |
| Suggested PSU | 750 W | 750 W |
| Hardware ray tracing | Yes | Yes |
| Upscaling support | FSR 3 | DLSS 2, FSR 3, XeSS |
| DirectX | 12 Ultimate | 12 Ultimate |
Green marks the stronger figure for that row only — for power draw and PSU requirement, lower is treated as better. Performance indexes are CanMyPcPlay estimates; read how they are derived.
Which should you pick?
- Check video memory, not just speed. A faster card with less VRAM can perform worse in recent titles at high texture settings.
- Check power and clearance. Confirm your PSU and case can take the card — the build checker does this.
- Upscaling support differs. DLSS is NVIDIA-only; FSR and XeSS run more broadly.
