Apple's M5 Pro Mac mini upgrade prices don't scale evenly -- memory and storage costs balloon at higher tiers
PCMag's $2,899 test unit took its Editors' Choice award, and the review credits the result to memory speed over raw capacity while memory is in short supply. The upgrade ladder tops out at 64GB.

What happened
- PCMag's test unit, with the faster M5 Pro chip, 48GB of memory, a 1TB SSD and 10Gbps Ethernet, cost $2,899, and the review gave it Editors' Choice among high-end mini desktops.
- The $1,699 entry configuration has a 15-core CPU, a 16-core GPU, 24GB of unified memory and a 512GB SSD, with a 2.5Gbps Ethernet jack as standard.
- Unified memory stops at 64GB while SSD options run to 8TB, and the fully loaded machine comes to $6,799, of which $3,800 is the largest drive.
- The same chassis now ships with either the base M6 or the M5 Pro, and PCMag rates the older Pro part considerably more powerful than the newer base one.

Why it matters
- cost Memory headroom is the most expensive thing on the order form relative to the machine: the 64GB option adds 59% of the base price, paid by the buyer who cannot predict their working set.
- constraint Above 64GB the chassis is out of the running at any price, and the route Apple offers is Thunderbolt 5 chaining. That means buying a second machine.
- contradiction PCMag's description of upgrade prices ballooning sits against a per-gigabyte rate that holds steady across tiers, so the sticker shock comes from capacity doubling and not from a worsening rate.
- decision With an M6 and an M5 Pro sold in the same box, the model number no longer ranks the machines, so buyers have to compare core counts at checkout instead of generation labels.
The row that decides this purchase is memory. Apple charges $600 to go from the base 24GB to 48GB and $1,000 to reach 64GB [5]. The last 16GB therefore costs $400 [1], which is $25 per gigabyte, the same rate as the first step [2]. PCMag wrote that the memory and storage bumps "no longer increase in even increments" and "rapidly balloon in cost" [10]. The totals climb because each rung roughly doubles capacity.
Storage prices the same way. Above the 512GB base, 1TB is $300, 2TB is $800, 4TB is $1,800 and 8TB is $3,800 [6]. Per terabyte added, that is $600, then $533, $514 and $507 [3].
The $2,899 review unit is the $1,699 base plus $600 of memory, $300 of SSD, $200 for the 18-core CPU and 20-core GPU, and $100 for 10Gbps Ethernet [9][7][4][4]. The $6,799 top configuration is that same list with 64GB and the 8TB drive [5].
The capacity-for-bandwidth story is PCMag's reading. The review credits the results to "Apple's prioritizing memory speed versus raw memory capacity" and calls capacity "a tough game to play amid ongoing shortages of memory" [11]. It does not state a memory bandwidth figure for the M5 Pro [12]. Anyone weighing this box against a higher-capacity Windows mini PC has a benchmark result plus an explanation of it, and the second part is the reviewer's inference.
Apple is also letting M5 Pro minis be chained over Thunderbolt 5 to share computational resources for larger AI models, which PCMag ties to the mini's growing popularity for AI work [15]. For a model that does not fit under the ceiling, that chain is the route on offer, and it means buying a second machine.
"The M5 Pro flavor of the Mac mini is for Mac-loyal professionals or Mac-curious ones," the review said [16]. For the Mac-curious, the first spec to compare is capacity: many similarly priced Windows mini-PCs ship 16GB, against 24GB here [14][3].
The first question is whether the working set fits under 64GB. If it does not, more budget does not help, because a $6,799 mini has the same memory ceiling as a $2,699 one [8]. If it does, buy memory before storage. The 8TB step is $3,800, which is $801 more than the base machine plus every other upgrade on the page combined [6].
What to watch
- Whether Apple publishes an M5 Pro memory bandwidth figure that would test PCMag's shortage explanation.
- Whether the next Mac mini revision raises the 64GB ceiling or holds it while memory supply stays tight.
- Whether the $25-per-gigabyte rate on Apple's configurator moves with DRAM contract pricing.
