Can I Run Ministral 3B on NVIDIA GeForce RTX 3070?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes. Ministral 3B needs 3.8 GB at 8K context (2.2 GB weights + 1.6 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 3070 has 8 GB, leaving about 4.2 GB of headroom, at roughly 86 tok/s (estimated) with room for up to 32K of context.

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 8 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 3070: 8K 3.8 GB · 32K 6.5 GB. Every window this model publishes still fits 8 GB.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
