Can I Run Mistral Small 3.2 on NVIDIA GeForce RTX 5080?
Written by Jakub Rusinowski · Last updated September 29, 2026
Only with offload — Mistral Small 3.2 24B at Q4_K_M needs 16.4 GB at 8K context (14.2 GB weights + 2.2 GB KV cache/overhead) against the NVIDIA GeForce RTX 5080's 16 GB, so part of it spills onto CPU/system RAM and speed drops sharply.

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 16 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 5080: 8K 16.4 GB ✗ · 32K 20.4 GB ✗ · 128K 36.5 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Mistral Small 3.2 24B on 16 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every Mistral Small 3.2 variant requires more VRAM than the NVIDIA GeForce RTX 5080 provides (16 GB).
Nearest GPU That Fits
AMD Radeon RX 7900 XT (20 GB VRAM).
Mistral Small 3.2 needs ~16 GB but this GPU has 16 GB. Rent a RTX 4090 (24 GB)-class GPU by the hour instead of buying one:
