Intel Arc B580 12GB

Intel Arc (Battlemage)

VRAM: 12 GB
Memory bandwidth: 456 GB/s
Class: Consumer

Figures assume this GPU plus 32 GB of system RAM (a typical desktop pairing). "What runs on it" is judged at a 8,192-token context. Speeds are estimates, not measurements.

Running local LLMs on Intel Arc — read this first

Non-NVIDIA cards run today's models, but the software stack is less mature. The practical picture as of July 2026:

Intel's Vulkan backend is roughly 2× its own SYCL / IPEX-LLM path for llama.cpp-style inference — prefer Vulkan builds unless a workload specifically needs SYCL.
No FlashAttention-3, NVLink, TensorRT-LLM or ExLlamaV2. Those NVIDIA-only accelerations don't exist here, so expect lower prompt-processing throughput and no multi-GPU NVLink pooling.
The estimated generation speeds on this page come from the memory-bandwidth roofline and hold across vendors; the caveats above mostly affect prompt processing and features, not raw decode tok/s.

Guidance reviewed July 2026 — the ROCm/Vulkan gap narrows over time.

"Est. speed" is a modelled range labelled estimate (D8) for generation (decode) throughput. "Community" shows the median of approved user-submitted reports on this GPU class only where enough exist — never an estimate. "pp" is measured prompt-processing (ingestion) throughput from approved community reports; rows without a measurement show none.
