BENCHMARK REPORT
Can I Run DeepSeek-V3 (671B Base/Chat) on Intel Arc A770 (16GB)?
Comprehensive technical verdict based on static weights, dynamic KV Cache (8k baseline context window), and CUDA runtime overhead.
Official Verdict
NO — CUDA OOM
Executive Hardware Compatibility Summary: DeepSeek-V3 (671B Base/Chat) on Intel Arc A770 (16GB)
Authoritative verdict, memory allocation, and token generation performance:
Direct Answer: CUDA OOM — Deficit of 395.2 GBDeepSeek-V3 (671B Base/Chat) exceeds dedicated physical VRAM and triggers PCIe layer offloading on Intel Arc A770 (16GB) (16GB). At standard Q4_K_M 4-bit quantization and an 8,192-token context window, total memory demand is 411.16 GB (408.64 GB weights + 0.57 GB dynamic KV cache + 1.15 GB OS & CUDA buffers). Physical VRAM is exceeded by 395.16 GB, forcing 59 transformer layers to offload across the PCIe bus to host DDR RAM. Estimated generation throughput is ~0.6 tokens/sec (~1666.7 ms per token) with prompt prefill processing reaching ~783 tok/s.

Hardware Compatibility Q&A: DeepSeek-V3 (671B Base/Chat) on Intel Arc A770 (16GB)
Technical answers for memory allocation, CUDA overhead, and execution parameters.
Can Intel Arc A770 (16GB) run DeepSeek-V3 (671B Base/Chat)?
CUDA OOM — Deficit of 395.2 GB. 59/61 layers will spill to CPU RAM, causing severe PCIe bandwidth throttling (est. 0.6 tok/s). At an 8k context window, total VRAM demand is 411.16 GB compared to Intel Arc A770 (16GB)'s 16 GB frame buffer.
How much VRAM does DeepSeek-V3 (671B Base/Chat) require?
At standard Q4_K_M quantization and 8k context, DeepSeek-V3 (671B Base/Chat) requires approximately 411.16 GB of VRAM. This includes 408.64 GB for model weights, 0.57 GB for dynamic KV cache (compressed using DeepSeek MLA), 0.8 GB for activation buffers, and 1.15 GB for OS display and CUDA runtime overhead.
What generation speed (tokens/sec) can I expect on Intel Arc A770 (16GB)?
Estimated autoregressive token generation speed is ~0.6 tokens per second with a per-token latency of ~1666.7 ms, powered by 560 GB/s memory bandwidth. Prompt prefill processing reaches ~783 tok/s (TTFT ~10462 ms).
What causes CUDA Out-of-Memory (OOM) when running DeepSeek-V3 (671B Base/Chat)?
CUDA OOM occurs when total memory consumption exceeds Intel Arc A770 (16GB)'s 16 GB physical VRAM. While model weights stay static, the KV cache grows with every conversation token. When VRAM fills up, inference engines (like Ollama or llama.cpp) must offload remaining layers across the PCIe bus (31.5 GB/s) to host system RAM, causing generation speed to drop sharply.
How do I run DeepSeek-V3 (671B Base/Chat) locally on Intel Arc A770 (16GB)?
You can run DeepSeek-V3 (671B Base/Chat) directly with Ollama using "ollama run deepseek-v3-671b". For advanced serving with vLLM or llama.cpp, copy the ready-to-run CLI commands in the CLI Commands section above with optimal context, quantization, and GPU layer offload parameters.

Frequently Asked Questions (FAQ)
Model weights are only one part of total VRAM consumption. When you prompt a model, the KV Cache (Key-Value Cache) stores all historical tokens. At 32k or 64k context, standard GQA attention can demand an additional 4GB to 12GB of VRAM! Combined with activation buffers and OS background consumption (0.8GB on Windows), total memory spikes beyond hardware capacity.
