Can I Run Codestral on NVIDIA GeForce RTX 4070 Ti?
Written by Jakub Rusinowski · Last updated September 29, 2026
No — Codestral 22B at Q4_K_M needs 16.1 GB at 8K context (13.4 GB weights + 2.7 GB KV cache/overhead), and the NVIDIA GeForce RTX 4070 Ti's 12 GB leaves it ~4.1 GB short. The cheapest card that runs it is the AMD Radeon RX 7900 XT (20 GB).

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 12 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 4070 Ti: 8K 16.1 GB ✗ · 32K 21.7 GB ✗. Past 8K it no longer fits 12 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 NVIDIA GeForce RTX 4070 Ti provides (12 GB).
Nearest GPU That Fits
