The Framework Desktop puts AMD's Strix Halo silicon into an open, repairable chassis aimed squarely at local AI. PCWorld awarded it 4.5/5 and an Editors' Choice, writing that 'it's not just for tinkering, this machine can legitimately run the latest AI models locally, something few desktops this size can do.' Of its 128 GB of LPDDR5X-8000 unified memory, AMD's driver can assign up to 96 GB as VRAM, enough to run GPT-OSS 120B, which AMD says runs about ten times faster than Llama 3 70B on this chip. ServeTheHome called it 'our third-favorite AMD Strix Halo mini PC so far,' and Tom's Hardware noted 'the mix of powerful graphics and plentiful RAM is why Framework is pushing this as an AI system.' Windows and Linux both run on it, so the full open-source AI stack is available in a way it isn't on the Mac Studio. Bandwidth and price are the limits.

Strengths
  • — Framework's hallmark repairability and documentation, including a customizable front tile panel
  • — Runs Windows or Linux, opening up the full open-source AI toolchain the Mac Studio cannot
  • — Compact 4.5-liter chassis that doubles as a capable productivity and 1080p gaming PC
Watch-outs
  • — Soldered LPDDR5X means no future memory upgrades despite Framework's repairable reputation
  • — Expensive versus a gaming PC with discrete graphics if you don't use the full 128 GB
  • — Requires some self-assembly, more involved than the plug-and-play mini PCs here

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

How they stack up

Framework Desktop (Ryzen AI Max+ 395)

It differentiates on platform and ethos: an open, repairable chassis running Windows or Linux, which the macOS-only Mac mini M4 Pro and Mac Studio M4 Max cannot match. Choose it for the most open 128 GB local-LLM box.

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.
