Episode #55 — Path B topdown. Тема о hardware floor — на каком минимуме GPU стек собирается.
→ alpha_d13_episode55.mp4 — hardware floor
Что в эпизоде
Voice (~32 sec): «Mini-server economics — может ли проект работать на меньшем GPU. RTX 3090 24 GB — Wan turbo помещается, 4DGaussians training работает, LatentSync OK. RTX 3060 12 GB — Wan tight, talking-head стек требует offload. RTX 2080 Ti 11 GB — большинство frontier models не fit. Floor для frontier-AI на single GPU — это около 24 GB. Below — components drop one by one. Project current 32 GB — comfortable middle. 48 GB upcoming — strategic headroom. Это hardware reality, не choice.»
VRAM tier breakdown
| GPU | VRAM | Wan 5B Turbo | Wan 14B | 4DGS train | LatentSync | Sharp | Verdict |
|---|---|---|---|---|---|---|---|
| RTX 5090 | 32 GB | ✓ | tight + offload | ✓ | ✓ | ✓ | current, comfortable |
| RTX 4090 48 GB | 48 GB | ✓ | ✓ | ✓ + longer scenes | ✓ | ✓ | upcoming, headroom |
| RTX 4090 | 24 GB | ✓ | offload | ✓ | ✓ | ✓ | floor |
| RTX 3090 | 24 GB | ✓ | offload | ✓ | ✓ | ✓ | floor (older arch) |
| RTX 4080 Super | 16 GB | ✓ tight | ✗ | ✓ | tight | ✓ | basic stack only |
| RTX 4070 Ti Super | 16 GB | ✓ tight | ✗ | ✓ | tight | ✓ | basic stack only |
| RTX 3060 | 12 GB | tight | ✗ | ✓ | offload | ✓ | minimal |
| RTX 2080 Ti | 11 GB | ✗ | ✗ | tight | ✗ | tight | below floor |
24 GB — пороговое значение. Below — frontier components drop progressively.
What 32 GB current enables
Все frontier components fit без offload (kроме Wan 14B):
- Wan 2.2 5B Turbo I2V — peak ~14 GB
- 4DGaussians training с 10-frame scene — ~8 GB
- LatentSync 1.6 — peak ~16 GB
- Apple SHARP — ~3 GB
- Hunyuan3D 2.1 + paint — peak ~15 GB
- Hunyuan-Foley — ~10 GB (isolated venv)
- Fish Speech 1.5 — ~5 GB
Single-GPU constraint означает не все simultaneously. Но any one component fits comfortably с remaining headroom для other concurrent task.
48 GB upcoming benefit
Wan 14B без offload (better quality / longer context) + multi-character scene (multiple 4DGS scenes loadable) + future CAP4D inference (predicted >32 GB peak).
Pipeline
