AMD Radeon RX 6900 XT vs AMD Radeon RX 6800 XT
The AMD Radeon RX 6900 XT and AMD Radeon RX 6800 XT 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.

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.
