The short answer

Apple Mac Studio M4 Max comes out ahead by a narrow margin (4.4 vs 4.3). Apple Mac Studio M4 Max is best for: Apple users who want the fastest local-LLM inference and 100B-class model headroom. Read the strengths below before deciding.

Ranked #2 in Best AI Mini PCs for Local LLM
Mac mini M4 Pro 64 GB
2 sources

The Mac mini M4 Pro is a five-inch-square box with a 12-core CPU, a 16-core GPU and 64 GB of unified memory, and it runs near-silently on very little power. PCMag rated it 4.5 out of 5 and Macworld 4 out of 5, landing on the same split verdict: the machine is excellent and the configuration pricing is not. For local-LLM work the 273 GB/s of memory bandwidth is the number that matters, and 64 GB is the hard ceiling that comes with it. Nothing inside is upgradable, so the configuration you buy is the one you keep.

Strengths
  • — Super fast and efficient M4 Pro SoC with 12 CPU cores and 16-core GPU
  • — Silent operation under average load with efficient cooling system
  • — Support for up to three external displays with Thunderbolt 5 and Wi-Fi 6E
Watch-outs
  • — 64 GB ceiling caps the largest local model — 70B Q4 fits, 120B does not

Bandwidth is what actually governs token speed, and the Mac Studio M4 Max has more of it than anything else in this group. At up to 546 GB/s it more than doubles the Mac mini M4 Pro's 273 GB/s and the Strix Halo boxes' 256 GB/s, and community testing puts 70B models at roughly 22-25 tokens/sec, far ahead of the rest of the field here. Macworld (4.5/5) and AppleInsider (4.5/5) both praised its performance and composure, with AppleInsider noting it is 'faster than the Apple Silicon Mac Pro, for half, and sometimes a quarter, of the price.' Its 128 GB unified memory ceiling fits 100B-class quants, and it stays cool and quiet doing it. The catch is the cost of the 128 GB configuration, and it is macOS-only, so Linux and CUDA tooling are out.

Strengths
  • — Highest memory bandwidth here at 546 GB/s, the single most important spec for token generation speed
  • — Thunderbolt 5 (120 Gb/s) and 10Gb Ethernet for fast external storage and networking
  • — Apple-silicon LLM toolchain is mature: MLX, Ollama, and llama.cpp's Metal backend all run natively
Watch-outs
  • — Expensive once configured with 128 GB of memory, and upgrades must be chosen at purchase
  • — Unified memory is soldered and configured at purchase, with steep Apple upgrade pricing

How they stack up

Mac mini M4 Pro 64 GB

The Mac mini M4 Pro 64 GB has 273 GB/s of memory bandwidth and a 64 GB memory ceiling, where the Apple Mac Studio M4 Max reaches 546 GB/s and up to 128 GB. Its 64 GB fits a 70B Q4 model but not a 120B one, which the GMKtec EVO-X2 loads in 128 GB at 256 GB/s.

Apple Mac Studio M4 Max

The Apple Mac Studio M4 Max matches the GMKtec EVO-X2 and the Framework Desktop (Ryzen AI Max+ 395) on a 128 GB memory ceiling, at 546 GB/s of memory bandwidth against their 256 GB/s. It has twice the Mac mini M4 Pro 64 GB's 273 GB/s bandwidth and twice its 64 GB of memory. The Framework Desktop runs Windows or Linux, which the macOS-only Mac Studio does not, and it costs less.
