NVIDIA GeForce GTX 1660 SUPER vs AMD Radeon RX 590
The NVIDIA GeForce GTX 1660 SUPER and AMD Radeon RX 590 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.

| Memory type | GDDR6 | GDDR5 |
| Memory bus | 192-bit | 256-bit (better) |
| Release year | 2019 (better) | 2018 |
| Board power | 125 W (better) | 175 W |
| Suggested PSU | 450 W (better) | 500 W |
| Hardware ray tracing | No | No |
| Upscaling support | FSR 3, XeSS | FSR 3 |
| DirectX | 12 | 12 |
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.
