# SCAIL 2 - BF16 vs. FP8

Currently in *Sprute*, SCAIL 2 is the heaviest VRAM user mainly due to 768x768 canvas and the need for diffusing 81-5 frames.

**Comparison**:

|  | BF16 | FP8 |
| --- | --- | --- |
| Peak PyTorch Memory | 44.85GiB | **35.07GiB** |
| Duration (s) | 308s | 330s |

**Results**:

**Discussions**:

*   There was no reduction in time.
    
*   But there was around 10 GiB (22%) saving on VRAM.
    
*   Still not good enough to fit into RTX 5090.
