### 4.5 GPU Training Benchmark (TinyLlama 1.1B, Tesla T4)
All methods trained with identical configuration: LoRA r=16, Ξ±=32, target=[q,k,v,o]_proj, batch=4Γ—4, lr=2e-4, 100 optimizer steps on Alpaca.
| Method | Final Loss | Training Time | GPU Memory | Relative Speed |
|--------|:-:|:-:|:-:|:-:|
| FP16 LoRA (gold standard) | 0.2252 | 1309s | 3,585 MB | 1.0Γ— |
| BnB NF4 QLoRA (industry default) | 0.2399 | 1423s | 2,441 MB | 0.9Γ— |
| **FigQuant LoRA (lowram mode)** | **0.2475** | **184s** | **10,181 MB** | **7.1Γ—** |
Key findings:
- **FigQuant is 7Γ— faster** than both FP16 and NF4 on GPU. The speed advantage comes from FigQuant's fused dequant-matmul path which avoids the overhead of bitsandbytes' per-tensor quantization/dequantization cycle.
- Loss is competitive: only 10% higher than FP16 (0.2475 vs 0.2252), and matches NF4 quality (0.2475 vs 0.2399).
- Memory is higher (10GB) because lowram mode re-dequantizes on every forward pass, creating temporary FP32 tensors. The `figcache` mode (not tested on GPU yet) should reduce this significantly while maintaining the speed advantage.
- FigQuant completed only 62/100 steps in the same wall-clock budget β€” the per-step speed is even faster than the total time suggests.
