A year ago Intel Arc was still a punchline for AI workloads. The Battlemage refresh (B580/B60) is the thing that changed that — and a year of driver, backend, and ecosystem work has made it genuinely good, with caveats. Here's where Arc actually stands for local AI in mid-2026.

We took Qwen3.6-27B at Q4_K_M — byte-identical weights, verified by Ollama digest — and ran it on all four lab machines: dual 12GB NVIDIA, single 20GB AMD, dual 32GB AMD, and a 24GB Intel Arc. The three CUDA/ROCm machines landed within 10% of each other. The honest answer to 'do I need two GPUs?' is: only once the model stops fitting in one.

Running Wan, Hunyuan Video, and CogVideoX locally — what's actually runnable on consumer GPUs, what isn't, and the optimizations that help. The honest version, because video is where local hardware hurts most.

What it actually takes to run Flux and Stable Diffusion on your own GPU — VRAM floors by model, GPU picks by budget tier, and the five optimizations that make marginal cards viable. No 'best GPU' list — the math.

We ran the same two 8B models on both cards with byte-identical weights and identical settings. The RX 7900 XT is ~3.9x faster — consistently across both architectures. Here's the full 2x2, what it actually tells you, and where we got the framing wrong the first time.

We benchmarked OpenVINO Model Server 2026.2.1 against llama.cpp Vulkan on the same Intel Arc Pro B60. OpenVINO is ~1.76x faster on a 30B-A3B model — and it works cleanly, contradicting our own earlier note that Battlemage was Vulkan-only. Here's the data and the correction.

Yes, really. A Q4_K_M 30B coder model fits in 12GB of VRAM and runs at usable speed on a single Intel Arc B580. Here's the recipe — with the numbers to back it.
