+# DGX Spark LLM Benchmarks
+
+First comprehensive benchmark suite for NVIDIA DGX Spark (GB10 Blackwell).
+
+## Hardware
+- **GPU:** NVIDIA GB10 Blackwell (1 PFLOP FP4)
+- **Memory:** 128GB unified LPDDR5x (273 GB/s)
+- **CPU:** 20-core ARM (10x Cortex-X925 + 10x Cortex-A725)
+- **Storage:** 4TB NVMe
+- **Framework:** Ollama 0.18.3
+- **CUDA:** 13.0 | Driver: 580.142
+
+## Benchmark Results
+
+### Run 1 — General Inference (11 models)
+
+| Model | Size | Prompt tok/s | Gen tok/s | Load Time |
+|-------|------|-------------|-----------|-----------|
+| Llama 3.1 8B | 4.9 GB | 574.79 | 42.86 | 4.73s |
+| Gemma3 27B | 17 GB | 164.64 | 11.71 | 9.83s |
+| Qwen2.5-Coder 32B | 19 GB | 288.96 | 10.36 | 15.13s |
+| Qwen3 32B | 20 GB | 141.91 | 9.88 | 4.08s |
+| CodeLlama 70B | 38 GB | 133.35 | 5.73 | 28.81s |

+| Mistral Large 123B | 73 GB | 10.43 | 2.28 | 86.14s |
+
+### Run 2 — Coding Benchmark
+
+| Model | Gen tok/s | Tokens Generated |
+|-------|-----------|-----------------|
+| Llama 3.1 8B | 42.51 | 369 |
+| Qwen2.5-Coder 32B | 10.33 | 552 |
+| Qwen3 32B | 9.38 | 8,180 |
+| CodeLlama 70B | 5.69 | 752 |
+| Gemma3 27B | 11.61 | 329 |
+| DeepSeek-R1 70B | 4.51 | 10,710 |
+| Llama 3.3 70B | 4.67 | 507 |
+
+### Run 3 — Context Scaling
+
+| Model | Short Prompt tok/s | Long Prompt tok/s | Scale | Gen tok/s |
+|-------|-------------------|-------------------|-------|-----------|
+| Llama 3.1 8B | 574 | 2,090 | 3.6x | 41.82 |
+| Gemma3 27B | 164 | 616 | 3.8x | 11.70 |
+| Qwen3 32B | 141 | 491 | 3.5x | 10.10 |
+| Llama 3.1 70B | 67 | 212 | 3.2x | 4.69 |
+| Qwen 2.5 72B | 122 | 225 | 1.8x | 4.33 |
+| Nemotron 70B | 87 | 164 | 1.9x | 4.62 |
+
+### Run 4 — Vision
+
+| Model | Size | Prompt tok/s | Gen tok/s | Load Time |
+|-------|------|-------------|-----------|-----------|
+| Llama3.2-Vision 90B | 54 GB | 6.02 | 3.47 | 16.86s |
+
+## Key Findings
+
+1. **27-32B is the sweet spot** — 10-12 tok/s, genuinely interactive
+2. **Prompt eval scales 3-4x** with longer prompts on unified memory
+3. **DeepSeek-R1 generates 10,710 tokens** of reasoning for one coding question
+4. **90B vision model runs** on a desktop at 3.47 tok/s
+5. **123B is the ceiling** — Mistral Large at 2.28 tok/s barely interactive
+6. **Generation speed is constant** regardless of prompt length
