Written by Jakub Rusinowski · Last updated September 29, 2026

Yes, comfortably — Mistral NeMo 12B at Q4_K_M needs 9.4 GB at 8K context (7.2 GB weights + 2.2 GB KV cache/overhead), leaving ~6.6 GB of the AMD Radeon RX 7800 XT's 16 GB, at ~43 tok/s (est.), with room for up to 32K context.

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.

Superseded model. Mistral Family has been superseded by Mistral Small 4. This page is kept for reference; the newer family is a better starting point. Mistral Small 4 needs at least 75.5 GB at Q4_K_M with an 8K context, so it does not fit the AMD Radeon RX 7800 XT.

Context costs VRAM too. At Q4_K_M on the AMD Radeon RX 7800 XT: 8K 9.4 GB · 32K 13.4 GB · 128K 29.5 GB ✗. Past 128K 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 NeMo 12B on 8 GB of system RAM, CPU only: runs, but it is tight.
