Mac Mini M4 Pro for Local AI: The $1,400 Workhorse Reviewed

The Mac Mini M4 Pro starts at $1,399 with 24GB unified memory and Apple's best efficiency in a desktop form factor. For local LLM users, unified memory means no VRAM wall — every gigabyte serves both GPU and CPU. This review covers real inference workloads.

Quick Setup on macOS

brew install ollama
ollama serve &
ollama pull qwen3.6:32b  # 20GB, fits in 24GB config with tight context
ollama run qwen3.6:32b

The key insight: 24GB unified memory is the minimum to run 32B models without swapping. The 48GB config gives you the same bandwidth (273 GB/s) with much more headroom for long contexts. For a full comparison with PC GPUs in this price range, see LLMHardware.io's Mac vs PC comparison.

Verdict: Best $1,400 LLM Machine?

At $1,399, the Mac Mini M4 Pro with 24GB competes directly with a mid-range PC build. It delivers 60-70% of a discrete RTX 4090's token speed on small models, whisper-quiet operation, and macOS software ecosystem. For 7B-14B models, it is genuinely excellent. For 32B+, upgrade to 48GB.

AMD RX 9070 XT for Local LLMs: ROCm Performance Guide (2026)

The AMD RX 9070 XT launched in early 2026 at $599 with 16GB GDDR6 and 648 GB/s memory bandwidth. For local LLM users who want a mid-range GPU without NVIDIA prices, this changes the calculus significantly. Here is what it actually delivers. RX 9070 XT Specs vs Competition GPU VRAM Bandwidth Price LLM Score RX 9070 XT 16 GB 648 GB/s $599 ~60 tok/s RTX 4070 Ti Super 16 GB 672 GB/s $799 ~62 tok/s RTX 4080 Super 16 GB 736 GB/s $999 ~68 tok/s RTX 4090 24 GB 1,008 GB/s ~$1,100 ~90 tok/s At $599 with 16GB VRAM, the RX 9070 XT is the best value GPU for local LLMs in the mid-range tier in 2026.

llama.cpp flash attention: how to enable and benchmark

Image
Flash attention computes attention with far less memory traffic. The math is identical; the memory movement is not. In llama.cpp it matters most in two situations: long context windows and tight video memory (VRAM). With flash attention enabled, the key-value cache shrinks substantially. A 32k-token context window becomes realistic on a 16GB card, and the prompt-processing phase speeds up, so long documents get ingested faster. The catch is compatibility: not every model and quantization combination supports it, and on some setups the speedup is modest. If you run short chats on a strong GPU, you may barely notice. Where it shines is retrieval-augmented generation (RAG) and long-document work on mid-range cards. Enable it, compare your tokens per second, and keep it if your workload benefits. For the common case of pasting a long PDF and asking questions, it is close to free performance. See how context length changes VRAM needs .
