Our results: Average time for one (diffusion) step (measured in seconds)
| Hardware | (512, 512) | (768, 768) |
|---|---|---|
| Nvidia RTX 8000 | 0.23s | 0.81 |
| Apple M1 Pro (16‑Core GPU) | 1.30s | 6.67 |
| Apple M1 Pro (10‑Core CPU) | 4.77s | 15.41 |
Average total time to generate one image using 200 diffusion steps:
- Nvidia RTX 8000: ~45s / ~2.5 min
- Apple M1 Pro (16‑Core GPU): ~4.3min / ~22min
- Apple M1 Pro (10‑Core CPU): ~15min / ~51min
Details
- We run the diffusion process for 50, 150 and 200 diffusion steps calculated the average time for one step
- Each run was repeated 5 times and results were again averages
- We did not use half-float precision, since it is not (yet) available for MPS at the moment (should also mainly affect memory allocation)
- Going beyond 768 was not able for the M1 with 32GB shared memory
