Phi 3 Medium 14B needs ~11.8 GB VRAM. Intel Arc B570 10GB has 10.0 GB. With Q3_K_S quantization, expect ~16 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.
Runtime ecosystem is narrower than CUDA
Intel GPUs can look attractive on memory per dollar, but local AI tooling, kernels, and model coverage are still broader and easier on CUDA today.
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.
Prefer CUDA if you want the path of least resistance
If your goal is maximum runtime coverage, easier troubleshooting, and better support for new local AI releases, CUDA is usually still the safer upgrade path.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Yes, Intel Arc B570 10GB can run Phi 3 Medium 14B at Q3_K_S quantization (Very compromised (needs ~1.1 GB host RAM)). The recommended Q4_K_M requires 13.5 GB which exceeds available memory, but at Q3_K_S it needs only 11.8 GB. Expected decode speed: 16.3 tok/s.
Phi 3 Medium 14B (14B parameters) requires approximately 13.5 GB at Q4_K_M quantization. On Intel Arc B570 10GB, it fits at Q3_K_S using 11.8 GB.
The recommended quantization is Q4_K_M, but on Intel Arc B570 10GB the best fitting quantization is Q3_K_S, which uses 11.8 GB.
On Intel Arc B570 10GB, Phi 3 Medium 14B achieves approximately 16.3 tokens per second decode speed with a time-to-first-token of 11890ms using Q3_K_S quantization.
For coding workloads, Phi 3 Medium 14B on Intel Arc B570 10GB receives a F grade with 10.7 tok/s and 4K context.
On Intel Arc B570 10GB, Phi 3 Medium 14B can safely use up to 7K tokens of context at Q3_K_S quantization. The model's official context limit is 128K, but available memory constrains the safe maximum.
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.
Often yes, if your goal is the easiest setup and the widest runtime support. Intel can offer attractive memory capacity, but CUDA still tends to win on tooling maturity, guides, kernels, and model coverage for local AI.
