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.' With 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.' It runs Windows or Linux, so the full open-source AI stack is available, unlike on the Mac Studio. Bandwidth and price are the limits.

Strengths
  • 128 GB LPDDR5X-8000 unified memory lets you assign up to 96 GB as VRAM for local models
  • Explicitly built and marketed for local LLM work; runs GPT-OSS 120B at usable speeds
  • Framework's hallmark repairability and documentation, including a customizable front tile panel
Watch-outs
  • Soldered LPDDR5X means no future memory upgrades despite Framework's repairable reputation
  • 256 GB/s bandwidth trails the Mac Studio M4 Max badly, so token speed is mid-pack
  • Expensive versus a gaming PC with discrete graphics if you don't use the full 128 GB

The Mac mini M4 Pro delivers exceptional performance and energy efficiency in a compact form factor, with its M4 Pro processor and 64 GB unified memory handling demanding multitasking tasks effortlessly. PCMag's Joe Osborne praised its silent operation and powerful specs, while Notebookcheck's Sebastian Bade noted its impressive build quality and high price point. However, reviewers consistently criticized the lack of upgradability, expensive configuration options, and limited warranty coverage. For local-LLM use, the 273 GB/s memory bandwidth makes it the fastest 64GB-class mini PC at this price; reviewer benchmarks put 70B Q4 inference at roughly 8–10 tokens/sec, making it ideal for buyers who need 70B-class models on a Mac. Step up to a Mac Studio if you need to run 120B+ models locally.

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
  • No maintenance options due to permanently soldered unified memory
  • High surcharges for RAM and SSD upgrades, especially with proprietary modules
  • Only 1-year warranty compared to industry standards

How they stack up

Framework Desktop (Ryzen AI Max+ 395)

The Framework Desktop runs the same AMD Ryzen AI Max+ 395 silicon and 128GB of unified memory as the GMKtec EVO-X2 and Beelink GTR9 Pro, so it fits the same 120B-class models at the same roughly 256 GB/s bandwidth, well below the Mac Studio M4 Max. 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. Versus the GMKtec EVO-X2 it trades some plug-and-play convenience for Framework's documentation and customizable tile front; versus the Beelink GTR9 Pro it gives up dual 10GbE networking. Choose it for the most open 128 GB local-LLM box.

Mac mini M4 Pro 64 GB

The Mac mini M4 Pro is the value Apple pick: at 273 GB/s it has higher bandwidth than the 256 GB/s Strix Halo boxes (GMKtec EVO-X2, Beelink GTR9 Pro, Framework Desktop) for single-user 70B inference, but it is capped at 64 GB, so it cannot hold the 120B-class models those 128 GB machines fit. The Mac Studio M4 Max doubles both its bandwidth and memory ceiling for roughly the price increase. Pick the Mac mini M4 Pro if your models top out near 70B and you want Mac polish and silence at a lower price than the Mac Studio M4 Max; step up to a 128 GB box if you need more headroom.
