On an RTX 5070 Ti (16 GB), SmolLM3 3B in Q4_K_M needs about 3,3 Go of video memory: it should fit. Estimated generation speed: ≈ 307 tokens/s.

Electricity / M tokens · 0,25 €/kWh
Calculation: Qwen2.5 3B measured at 305 tok/s on this card, 1,8 Go read per token → × 1,8 Go ÷ 1,8 Go ≈ 307 tok/s (generation is memory-bound: speed follows the amount of weights read).

Estimated VRAM = file + KV cache (full-attention layers, f16) + ~0,5 Go of buffers, excluding memory used by the system — hence the slightly higher “recommended VRAM”, which keeps that margin. Speed ≈ estimated speed × weights read ÷ (weights read + added KV cache).
Estimates based on real measurements of other models on this card and on the model's public data (Petits modèles). As soon as a measurement exists, this page shows the real figures.
