Summary
Reasons to consider the Radeon RX 6600 XT
- 90 watts lower power draw. This might be a strong point if your current power supply is not enough to handle the Radeon RX Vega 64 Nano .
- This is a much newer product, it might have better long term support.
- Supports Direct3D 12 Async Compute
- Supports FreeSync
- Supports ReLive (allows game streaming/recording with minimum performance penalty)
- Infinity Cache allows to deliver up to 3.25x the effective memory bandwidth
- Supports DirectX Raytracing (DXR)
Reasons to consider the Radeon RX Vega 64 Nano
- Supports Direct3D 12 Async Compute
- Supports FreeSync
- Supports ReLive (allows game streaming/recording with minimum performance penalty)
- Supports TrueAudio
- Based on an outdated architecture (AMD GCN), there may be no performance optimizations for current games and applications
