Head-to-head · Best AI Mini PCs for Local LLM

Framework Desktop (Ryzen AI Max+ 395) vs Apple Mac Studio M4 Max

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Apple Mac Studio M4 Max comes out ahead by a narrow margin (4.4 vs 4.5). The gap is mostly about Apple users who want the fastest local-LLM inference and 100B-class model headroom — read the strengths below before deciding.

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 Studio M4 Max is the highest-performance local-LLM machine in this group, built around the bandwidth that actually governs token speed. 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, dramatically faster than the others 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 while staying cool and quiet. The catch is price: it costs roughly double the 128 GB GMKtec EVO-X2 or Beelink GTR9 Pro, 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
  • Up to 128 GB unified memory runs 70B models at roughly 22-25 tokens/sec and fits 100B-class quants
  • Stays cool and near-silent even under sustained inference, with no thermal throttling reported
Watch-outs
  • By far the most expensive pick here, roughly double the 128 GB Strix Halo boxes
  • Unified memory is soldered and configured at purchase, with steep Apple upgrade pricing
  • macOS only, so Linux/CUDA-native AI tooling is off the table

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.

Apple Mac Studio M4 Max

The Mac Studio M4 Max posts the highest memory bandwidth in this group at 546 GB/s, roughly double the Mac mini M4 Pro (273 GB/s) and the GMKtec EVO-X2 and Beelink GTR9 Pro (256 GB/s), which is why it generates tokens fastest on 70B models. Its memory ceiling of 128 GB matches the Strix Halo boxes for model size but at far higher bandwidth and price. Choose it over the Mac mini M4 Pro when you need both more than 64 GB and the fastest Apple inference; choose a GMKtec EVO-X2 or Framework Desktop instead if you want 128 GB on Linux or Windows at a fraction of the cost.
