The short answer

Mac mini M4 Pro 64 GB comes out ahead by a narrow margin (4.6 vs 4.5). The gap is mostly about Best for Mac users — highest bandwidth in 64 GB tier — read the strengths below before deciding.

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
  • — 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

Apple Mac Studio M4 Max
Ranked #2 in Best AI Mini PCs for Local LLM

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 price: 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

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.

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.
