Technical analysis of hardware configuration
FantasyTalking's performance needs stem from its advanced technical architecture:
- Wan2.1 model uses 14 billion parameter scales and requires 24GB+ of video memory for full loading
- Dynamic resolution rendering system automatically adjusts computational load based on GPU capabilities
- Memory optimization schemes include: gradient checkpoints, activation value compression and hierarchical computation
Suggested Configuration Options:
| resolution (of a photo) | Minimum GPU | memory utilization |
|---|---|---|
| 256 x 256 | RTX 2080 | 12GB |
| 512 x 512 | RTX 3090 | 20GB |
| 720P | A100 40GB | 38GB |
The project team says that future versions are expected to reduce 720P requirements to 24GB of video memory through distributed inference and model quantization techniques.
