# Meta LLaMA 3.2 11B Vision Instruct VRAM Requirements & Hardware Sizing Guide

> **Quick Summary (Answer Capsule)**: Running Meta LLaMA 3.2 11B Vision Instruct requires 11.05 GB at Q4_K_M (4-bit), 18.00 GB at Q8_0 (8-bit), and 31.05 GB at FP16. Recommended hardware sweet spot: Intel Arc B580 12GB. Scaling context past 32k tokens requires enabling FP8 KV-cache (-ctk q8_0) to prevent CUDA allocation failures.

## Memory Specifications by Precision
| Quantization Format | Precision Level | Required VRAM (8k context) | Quality Retention | Minimum Recommended GPU |
|---|---|---|---|---|
| 4-Bit (Q4_K_M) | Recommended Default | 11.05 GB | >98.2% Perplexity | Intel Arc B580 12GB |
| 8-Bit (Q8_0) | Near Lossless | 18.00 GB | ~99.9% Perplexity | Workstation / High-Tier GPU |
| 16-Bit (FP16/BF16) | Uncompressed Full | 31.05 GB | 100% Fidelity | Multi-GPU / Datacenter |

## Architectural Memory Analysis
Meta LLaMA 3.2 11B Vision Instruct combines a 32-layer GQA text decoder with an integrated 2.8B parameter vision cross-attention adapter and image encoder (total 13.8B parameters). Processing high-resolution images alongside 128k text context, standard Q4_K_M weights require 8.4 GB, with total memory reaching 11.2 GB at 8k context, fitting comfortably on 12GB–16GB graphics cards.

## Tier 1 Free Software Optimization ($0)
In llama.cpp, pass `-mmproj` with the vision projector file and enable `-fa on`. For multi-image analysis on 12GB GPUs, set `OLLAMA_KV_CACHE_TYPE=fp8` to prevent image token embeddings from overflowing VRAM.
