Can I Run Llama 3.2 3B Instruct on NVIDIA GeForce RTX 4070?

Autor: Jakub Rusinowski · Ostatnia aktualizacja: 11 września 2026

Yes. Llama 3.2 3B Instruct needs 1.9 GB at Q4_K_M and the NVIDIA GeForce RTX 4070 has 12 GB, leaving about 10.1 GB of headroom, at roughly 135 tok/s (estimated) with room for up to 64K of context.

The numbers

Llama 3.2 3B Instruct on the NVIDIA GeForce RTX 4070: VRAM by quantization

Assumes a 4K-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: 8K 3.7 GB · 32K 6.5 GB · 125K 17.4 GB ✗. Past 125K it no longer fits 12 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.
