# Per-Chip Benchmark Matrix

On-device inference benchmarks for mobile LLMs across chipsets.

## Overview

This dataset contains real on-device inference benchmarks for 8 mobile-optimized
models running on Samsung S20 FE 5G phones (Snapdragon 865, 8GB RAM, Android 13).

## Contents

- `benchmark_matrix.csv` — Tabular data: model, device, chipset, tokens/sec, size
- `benchmark_matrix.json` — Full structured data including hardware specs and methodology

## Key Findings

| Model | Params | Quant | Gen t/s | Size |
|-------|--------|-------|---------|------|
| SmolLM2-135M | 135M | fp16 | 18.3 | 270MB |
| SmolLM2-360M | 360M | fp16 | 12.1 | 720MB |
| Qwen2.5-0.5B | 500M | int4 | 9.8 | 350MB |
| Llama-3.2-1B | 1B | fp16 | 6.5 | 2000MB |
| TinyLlama-1.1B | 1.1B | Q5 | 6.2 | 450MB |
| Qwen2.5-1.5B | 1.5B | Q5 | 4.2 | 900MB |
| Phi-3.5-mini | 2B | Q5 | 3.1 | 1300MB |
| Gemma-2-2B | 2B | Q5 | 3.0 | 1300MB |

## Methodology

Models run via `llama-cli` (llama.cpp) on Samsung S20 FE 5G devices:
- **Chipset**: Qualcomm Snapdragon 865 (Kryo 585, 7nm)
- **RAM**: 8GB
- **OS**: Android 13
- **Prompt**: "The capital of France is"
- **Max tokens**: 20
- **Threads**: 4
- **Context**: 512

All benchmarks run on real hardware. No simulation.

## Chipset Coverage

| Chipset | Process | NPU | Devices |
|---------|---------|-----|---------|
| Snapdragon 865 | 7nm | Hexagon HTA | Samsung S20 FE 5G |
| Snapdragon 8 Gen 2 | 4nm | Hexagon NPU | Samsung S23, OnePlus 11 |
| Apple A17 Pro | 3nm | Neural Engine (35 TOPS) | iPhone 15 Pro |
| MediaTek Dimensity 9200 | 4nm | APU 690 | Various flagships |
