Can I Run Codestral on AMD Radeon RX 9070?
Written by Jakub Rusinowski · Last updated July 12, 2026
Only with offload — Codestral 22B at Q4_K_M needs 16.1 GB at 8K context (13.4 GB weights + 2.7 GB KV cache/overhead) against the AMD Radeon RX 9070's 16 GB, so part of it spills onto CPU/system RAM and speed drops sharply.

Codestral 22B on the AMD Radeon RX 9070: 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 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 AMD Radeon RX 9070: 8K 16.1 GB ✗ · 32K 21.7 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? Codestral 22B on 16 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every Codestral variant requires more VRAM than the AMD Radeon RX 9070 provides (16 GB).
Nearest GPU That Fits
AMD Radeon RX 7900 XT (20 GB VRAM).
Codestral needs ~16 GB but this GPU has 16 GB. Rent a RTX 4090 (24 GB)-class GPU by the hour instead of buying one:
