Official Verdict
YES — Runs Smoothly
Executive Hardware Compatibility Summary: Qwen 2.5 Coder 14B Instruct on NVIDIA GeForce RTX 5080
Authoritative verdict, memory allocation, and token generation performance:
Direct Answer: Can Run PerfectlyQwen 2.5 Coder 14B Instruct runs smoothly with 100% dedicated VRAM allocation on NVIDIA GeForce RTX 5080 (16GB). At standard Q4_K_M 4-bit quantization and an 8,192-token context window, total memory demand is 11.94 GB (8.95 GB weights + 1.59 GB dynamic KV cache + 1.15 GB OS & CUDA buffers). Physical GPU memory provides 4.06 GB of free safety buffer, preventing PCIe memory bus throttling. Estimated generation throughput is ~80.1 tokens/sec (~12.5 ms per token) with prompt prefill processing reaching ~3186 tok/s.

Hardware Compatibility Q&A: Qwen 2.5 Coder 14B Instruct on NVIDIA GeForce RTX 5080
Technical answers for memory allocation, CUDA overhead, and execution parameters.
Can NVIDIA GeForce RTX 5080 run Qwen 2.5 Coder 14B Instruct?
Can Run Perfectly. Entire model & KV cache fit fully into VRAM with pure GPU acceleration. At an 8k context window, total VRAM demand is 11.94 GB compared to NVIDIA GeForce RTX 5080's 16 GB frame buffer.
How much VRAM does Qwen 2.5 Coder 14B Instruct require?
At standard Q4_K_M quantization and 8k context, Qwen 2.5 Coder 14B Instruct requires approximately 11.94 GB of VRAM. This includes 8.95 GB for model weights, 1.59 GB for dynamic KV cache (Grouped-Query Attention (GQA)), 0.25 GB for activation buffers, and 1.15 GB for OS display and CUDA runtime overhead.
What generation speed (tokens/sec) can I expect on NVIDIA GeForce RTX 5080?
Estimated autoregressive token generation speed is ~80.1 tokens per second with a per-token latency of ~12.5 ms, powered by 1024 GB/s memory bandwidth. Prompt prefill processing reaches ~3186 tok/s (TTFT ~2571 ms).
What causes CUDA Out-of-Memory (OOM) when running Qwen 2.5 Coder 14B Instruct?
CUDA OOM occurs when total memory consumption exceeds NVIDIA GeForce RTX 5080'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 Qwen 2.5 Coder 14B Instruct locally on NVIDIA GeForce RTX 5080?
You can run Qwen 2.5 Coder 14B Instruct directly with Ollama using "ollama run qwen-2-5-coder-14b". 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.
