Verdict

Yes, but it's tight. Phi-4 14B is a 9.1 GB download (Q4_K_M). The Arc B580 gives the GPU 12 GB, leaving about 2.9 GB, so keep the context short (our estimate).

Does it fit?

Phi-4 14B memory	9.1 GB at Q4_K_M (Ollama: phi4 tags)
Arc B580 GPU memory	12 GB of VRAM (product listing).
Left over	About 2.9 GB (our arithmetic)
Verdict	Tight Under 4 GB to spare (our estimate bands)

Recommended quantization and context

Use the Q4_K_M build that Ollama's tag downloads; the memory figure above is for that build. The model supports up to 16K of context, but longer context uses more memory. Ollama starts at a 4096-token context by default (Ollama FAQ).

With only about 2.9 GB spare, keep the default context. If ollama ps shows part of the model on the CPU, shorten the context or pick a smaller model.

Run it

ollama run phi4:14b

Then check it's on the GPU:

ollama ps

The PROCESSOR column should read 100% GPU. Driver setup for Intel cards on Windows, Linux and macOS, plus common fixes, is in the install and run section.

FAQ

Can the Arc B580 run Phi-4 14B?

Yes, but tight: Phi-4 14B needs 9.1 GB (Q4_K_M, Ollama library) and the Arc B580 gives the GPU 12 GB, leaving about 2.9 GB. Keep the 4096-token default context. The fit bands are our estimate.

How much VRAM does Phi-4 14B need?

9.1 GB for the Q4_K_M build in the Ollama library, plus roughly 1–4 GB for context and runtime (our estimate). See the 12 GB page for other models that fit.

What command runs Phi-4 14B?

ollama run phi4:14b. Then run "ollama ps" and check the PROCESSOR column reads 100% GPU.

How fast is Phi-4 14B on the Arc B580?

We don't list a speed because we have no sourced measurement for this pairing. Speed depends on memory bandwidth, quantization and context length.
