How much VRAM does Mistral Small 3.2 24B need?

At Q4_K_M with 8K context: 14.7GB weights + 1.3GB KV cache + 1.5GB runtime overhead = 17.5GB total. RTX 5090 offers 32.0GB usable VRAM, so the verdict is: Comfortable.

What is the best quantization for Mistral Small 3.2 24B on RTX 5090?

Q8_0 — the highest tier that still fits within 32.0GB usable VRAM at 8K context. Lower tiers (Q3/Q2) fit too but cost noticeable quality.

How fast does Mistral Small 3.2 24B run on RTX 5090?

About 53 tokens/s at Q8_0 (theoretical estimate, ±30% in real-world use).
