Qwen 2.5 14B needs ~12.0 GB VRAM. RTX 3080 10GB has 10.0 GB. With Q3_K_S quantization, expect ~43 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Offload
30%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 20% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 1.1 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RTX 3080 10GB can run Qwen 2.5 14B at Q3_K_S quantization (Very compromised (needs ~1.1 GB host RAM)). The recommended Q4_K_M requires 13.7 GB which exceeds available memory, but at Q3_K_S it needs only 12.0 GB. Expected decode speed: 43.3 tok/s.
Qwen 2.5 14B (14B parameters) requires approximately 13.7 GB at Q4_K_M quantization. On RTX 3080 10GB, it fits at Q3_K_S using 12.0 GB.
The recommended quantization is Q4_K_M, but on RTX 3080 10GB the best fitting quantization is Q3_K_S, which uses 12.0 GB.
On RTX 3080 10GB, Qwen 2.5 14B achieves approximately 43.3 tokens per second decode speed with a time-to-first-token of 4472ms using Q3_K_S quantization.
For coding workloads, Qwen 2.5 14B on RTX 3080 10GB receives a F grade with 28.4 tok/s and 4K context.
On RTX 3080 10GB, Qwen 2.5 14B can safely use up to 5K tokens of context at Q3_K_S quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.
