Can I Run Mistral NeMo 12B on AMD Radeon RX 7900 XT?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 12 lipca 2026
Yes. Mistral NeMo 12B needs 9.4 GB at 8K context (7.2 GB weights + 2.2 GB KV cache/overhead) at Q4_K_M and the AMD Radeon RX 7900 XT has 20 GB, leaving about 10.6 GB of headroom, at roughly 53 tok/s (estimated) with room for up to 64K of context.

Mistral NeMo 12B on the AMD Radeon RX 7900 XT: 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 20 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 AMD Radeon RX 7900 XT: 8K 9.4 GB · 32K 13.4 GB · 128K 29.5 GB ✗. Past 128K it no longer fits 20 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
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.
