Apple routes the 64GB Mac mini buyer to last year's chip
The $899 M6 mini doubles the neural engine to 32 cores and stops at 32GB of soldered memory. Anyone who needs 64GB resident pays $2,699 for the M5 Pro and takes a 16-core neural engine instead.

What happened
- Apple's M6 Mac mini starts at $899 with a 12-core CPU, a 12-core GPU, a dual 16-core neural engine, 16GB of unified memory and a 256GB SSD.
- The same enclosure also ships with the year-older M5 Pro from $1,699, where 48GB of memory costs $2,299, 64GB costs $2,699, and a fully loaded 8TB unit reaches $6,799.
- The M5 Pro keeps the standard M5's 16-core neural engine, half the 32 neural engine cores Apple put in the cheaper M6 chip.

Why it matters
- constraint Memory is not upgradeable, so the largest model a team can keep resident is fixed on the day the purchase order goes in and cannot be repaired later with a $200 stick of RAM.
- decision Any team that needs more than 32GB resident must buy the older M5 Pro, trading half the neural engine cores for memory capacity.
- cost The upgrade path lands hardest on the always-on buyer: $400 of memory and $200 of storage turn an $899 desktop into a $1,499 one, before a display or keyboard is added.
- contradiction ZDNET's reviewer steers most buyers to the M5 Pro, while the doubled neural engine exists only in the cheaper M6, so the two recommendations answer different questions about the same box.
Unified memory decides how big a model an always-on box can hold, and on the M6 Mac mini it stops at 32GB [12]. ZDNET's review notes the memory is not upgradeable [9], so that ceiling is picked at checkout. Each 8GB step costs $200 [10], which works out at $25 a gigabyte [1]. An M6 with 32GB and a 512GB SSD comes to $1,499: the $899 base, $400 of memory, $200 of storage [2].
The other route is the older chip. The M5 Pro mini starts at $1,699 with a 15-core CPU, 24GB and a 512GB SSD, and ZDNET prices 64GB at $2,699 [13]. Per gigabyte of unified memory the expensive box is the cheaper one at its ceiling: about $42 a gigabyte against roughly $47 for the maxed M6 [3]. ZDNET said the effects of Ramageddon are most noticeable at the high end [16].
The M5 Pro buyer gives up the part Apple upgraded. CNET reports the M5 Pro carries the same 16-core neural engine as the standard M5, not the M6's dual 16-core design [14]. Both chips do have the GPU neural accelerators Apple introduced with the M5 [15].
So the split in the line sends the local-model buyer away from the newer silicon. A model that fits in 16GB or 24GB runs on the box with twice the neural engine cores, at $899 or $1,099 [1][6]. Anything that needs more than 32GB resident sends you to a chip a generation behind. PCMag describes the M5 Pro as considerably more powerful than the M6, especially in multi-core work [19], and ZDNET's reviewer wrote: "I'd recommend opting for the M5 Pro unless you explicitly don't need the memory and higher-end hardware in the Pro" [17].
"In the year of the AI agent, Apple's Mac Mini has enjoyed a surge in popularity to the point of dwindling supplies and long wait times," CNET wrote [7], adding that it has become a popular pick for people running OpenClaw and other local AI agents around the clock, and that older M4 minis have been increasingly difficult to find in recent months [8]. Only CNET reports this. None of the four reviews includes a sales figure or an Apple statement about who is buying, and none published a local-model benchmark.
The base price has risen since 2024. The mini launched with the M4 at $599 in 2024 and went to $799 earlier this year before the M6 took it to $899 [4], a $300 increase, or 50% [4]. It is no longer the cheapest Mac, since the $699 MacBook Neo took that slot this spring on an A18 Pro, but it is still the cheapest Mac with an M-series chip [6].
How many gigabytes the thing you run needs resident comes first. Then whether that work leans on the neural engine or on the GPU cores. Under 24GB, PCMag's $1,299 configuration with 24GB and a 512GB SSD is the buy, and PCMag wrote that it "outperforms mini PCs powered by the latest silicon from AMD and Intel, some of them costing more than twice as much as our $1,299 review configuration" [18]. Above 32GB there is no M6 configuration to buy, and the bill is $2,699 for 64GB on a 16-core neural engine [13][14].
What to watch
- Whether Apple later offers 48GB or 64GB on an M6-class mini, which would close the gap between NPU cores and memory capacity.
- Whether M6 mini stock repeats the M4 shortage CNET describes, or Apple has built for the new demand.
- Whether any reviewer publishes local-model throughput comparing the M6's 32 neural engine cores with the M5 Pro's 16.
