FantasyTalking's System Requirements Reflect Hardware Needs for High Quality Video Generation

2025-08-24 1.0 K

硬件配置的技术解析

FantasyTalking的性能需求源于其先进的技术架构:

  • Wan2.1模型采用140亿参数规模,需要24GB+显存完整加载
  • 动态分辨率渲染系统根据GPU能力自动调整计算负载
  • 内存优化方案包括:梯度检查点、激活值压缩和分层计算

建议配置方案:

resolution (of a photo) 最低GPU memory utilization
256×256 RTX 2080 12GB
512×512 RTX 3090 20GB
720P A100 40GB 38GB

项目组表示,通过分布式推理和模型量化技术,未来版本有望将720P需求降低到24GB显存。
