Can I Run Mistral Small 3 (24B) on NVIDIA GeForce RTX 4070?
Written by Jakub Rusinowski · Last updated July 12, 2026
Not at Q4_K_M — that needs 17.2 GB at 8K context and the NVIDIA GeForce RTX 4070 has 12 GB. Drop to Q2_K and it fits in 10.6 GB, with up to 8K of context.

Mistral Small 3 (24B) on the NVIDIA GeForce RTX 4070: VRAM by quantization

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 12 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 4070: 8K 17.2 GB ✗ · 32K 22.8 GB ✗. Past 8K it no longer fits 12 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Quantize to Q2_K. That is the cheapest fix — it costs some quality but no money.
