How to read the verdicts

Runs great: Fully on the GPU at 20 tok/s or more
Runs well: Fully on the GPU at 8–20 tok/s; MoE experts in system RAM at 20 tok/s or more; or at least 90% on the GPU at 8 tok/s or more
Runs slowly: 2–8 tok/s; CPU-only; less than 90% on the GPU; or MoE experts in system RAM below 20 tok/s
Won't run: Does not fit, or under 2 tok/s

Every model on the Intel Arc B580

Dense models split between GPU and CPU slow down sharply — the CPU side sets the pace. MoE models that keep only their experts in system RAM degrade far more gently.

Models with a thinking mode spend extra tokens thinking, so their speed thresholds are 1.5× stricter (30 / 12 / 3 tok/s). With thinking turned off, a model may do one grade better.

Frequently asked questions

What is the largest model that runs entirely on the Intel Arc B580?

Kanana 1.5 15.7B-A3B at IQ4_XS (a 8.71 GB file) fits entirely in 12 GB with 8k context, at est. 72.0 tok/s (50.4–93.6, theoretical estimate ±30%).

How many local LLMs run well on the Intel Arc B580?

At Q4_K_M with 8k context, out of 59 tracked models: 24 run great, 11 run well, 14 run slowly and 10 won't run.

Can the Intel Arc B580 run a 70B model like Llama 3.3 70B?

Runs slowly — Partial offload, Q2_K (heavy quality loss): est. 2.1 tok/s (1.7–2.5, calibrated estimate ±20%).

Speeds are estimates from memory bandwidth, calibrated against public benchmarks, and each one comes with an error band and a confidence label. Real results vary with drivers, backend, context length and thermals.
