A used M2 Pro Mac mini now costs $9 less than an M4 with the same memory and storage

Secondhand M2 Pro and M4 minis with 16GB of memory and 512GB of storage have median asking prices of $949.99 and $958.87. The $8.88 gap makes the workload, not the price, the deciding factor.

The used M2 Pro Mac mini has lost its Pro price premium. A 2023 model with 16GB of memory and a 512GB SSD now carries a $949.99 median asking price. The equivalent 2024 M4 configuration is $958.87. The difference is $8.88.

That does not make the M2 Pro the automatic bargain. It makes this a nearly price-neutral choice between an older Pro chip and a newer base chip.

You can check the live offer mix for the M2 Pro 16GB/512GB and M4 16GB/512GB configurations. The market figures below remain the fixed Sept. 2 comparison panel.

Mac mini configuration Price n Observed range
M2 Pro, 10-core CPU / 16-core GPU, 16GB / 512GB $949.99 median ask 21 $673.71-$1,254.95
M4, 10-core CPU / 10-core GPU, 16GB / 512GB $958.87 median ask 48 $759-$1,399
M6, 12-core CPU / 12-core GPU, 16GB / 512GB $1,099 list; $1,069.99 at Amazon, Sept. 16 (MacRumors) — New, ships Sept. 22

The new M6 costs $149.01 more than the M2 Pro median and $140.13 more than the M4 median when memory and storage are held constant. Apple’s $899 M6 starting price buys only 256GB of storage. Buyers who need 512GB should not compare that base price with these secondhand machines.

At Amazon’s $1,069.99 preorder price, the gaps narrow to $120.00 over the M2 Pro median and $111.12 over the M4 median.

Which Mac mini fits your job?

Start with storage, then the work you do most. Used prices are the fixed Sept. 2 medians; they are asks, not sales.

Which Mac mini fits your job Five rows, each pairing a buyer’s situation with a Mac mini to start from. If 256GB of storage is enough, start with a new M6 with 16GB and 256GB at its $899 Apple list price announced with a Sept. 22 ship date, or a used M4 with 16GB and 256GB at a $749 median ask across 134 listings; check a listing against the price ladder. For mostly browser, office and code-build work, the highlighted default, start with a used M4 with 16GB and 512GB at a $958.87 median ask across 48 listings; it leads the M2 Pro by 36.4% single-core and 12.5% multi-core. It has no USB-A ports, and the scores are Geekbench chart averages. For GPU-heavy creative work or many ports, start with a used M2 Pro with 16GB and 512GB at a $949.99 median ask across 21 listings; it has a 49.1% Metal lead, four Thunderbolt ports and two USB-A ports. Aim below the median and verify the cores in System Report. For local AI models, compare memory bandwidth, which predicts generation speed: M2 Pro 200GB/s, M6 up to 170GB/s and M4 120GB/s. No M6 has been measured yet. If you want a new machine with warranty, Wi-Fi 7 and 2.5Gb Ethernet, start with a new M6 with 16GB and 512GB at its $1,099 Apple list price, $140 to $149 more than either used median; Apple’s speed claims have not been independently tested. Used prices are median asks observed Sept. 2, 2026; they are asks, not sales. New prices are Apple list prices.

The M4 is the faster general-purpose Mac

The M4’s two-year advantage shows in processor work. Our Aug. 22 Geekbench 7 chart references put the 10-core M4 at 3,276 single-core and 15,349 multi-core. The 10-core M2 Pro scores 2,401 and 13,639. That gives the M4 a 36.4% lead on single-core work and a 12.5% lead across all cores.

Those are synthetic chart averages, not a promise about every application. They still resolve the ordinary desktop decision. At essentially the same asking price, the M4 is the stronger default for browsing, office work, code builds and other CPU-led use. It is also a 2024 machine in Apple’s smaller five-inch enclosure.

The M4 technical specifications add two front USB-C ports and support three displays. Its three rear USB-C ports are Thunderbolt 4. Buyers moving from the 2023 enclosure should notice what disappeared: there are no USB-A ports.

The M2 Pro still has a real graphics and bandwidth case

The M2 Pro reverses the benchmark result on graphics. Its Geekbench 7 Metal reference is 77,331 against 51,880 for M4, a 49.1% lead. Apple specifies 200GB/s of memory bandwidth for M2 Pro, 66.7% more than the M4’s 120GB/s.

In llama.cpp’s community benchmark of LLaMA 7B at Q4_0, as rechecked Sept. 15, the M2 Pro with a 16-core GPU generated 37.87 tokens per second and the M4 generated 24.11, about 57% faster for the older chip. Each is a single community run on a reference quantization, not our test; our Mac speed answer sets those figures beside these prices.

That makes the older machine the more interesting $950 choice for GPU-heavy creative work, bandwidth-sensitive local models and a desk that needs its ports. The M2 Pro mini has four Thunderbolt 4 ports and two USB-A ports. The media engine handles H.264, HEVC, ProRes and ProRes RAW on both machines; M4 adds AV1 decode.

The Metal comparison needs a boundary. Geekbench publishes GPU-family chart averages that can combine core-count variants, and a synthetic GPU lead does not guarantee the same margin in an editor, renderer or game. A buyer with one critical application should check a benchmark from that application before choosing the older Pro chip.

The M6 premium buys certainty before it buys proof

Apple’s 16GB/512GB M6 configuration is $1,099. That extra $140-$149 buys a new machine directly from Apple, standard warranty coverage, eligibility for new AppleCare coverage and the new model’s connectivity. It also buys a processor that has not been independently tested yet.

Apple says the 12-core M6 delivers 40% faster CPU performance and up to twice the graphics performance of M4. It specifies memory bandwidth up to 170GB/s, Wi-Fi 7, Bluetooth 6 and 2.5Gb Ethernet. The machine ships Sept. 22. Until reviewers can measure it, those are manufacturer claims and specifications, not a completed performance test.

If waiting for the M6 is the reason you are hesitating, our Sept. 22 timing page covers what changes for these secondhand asks once the new machines ship.

There is one easy M6 case: a buyer who needs only 256GB can preorder the $899 base model for less than either secondhand median. External storage may erase some of that saving, but the lower entry price changes the comparison. Our Mac mini storage guide prices a larger internal drive against adding an external one.

Which Mac mini should you buy around $1,000?

For the short answer by storage and workload, use the chooser above.

Buy the M4 16GB/512GB for the fastest general-purpose machine in the current secondhand market. There is no reason to accept its $1,399 high-end asks; the median is below $960 and several observed offers were below $850.

Buy the M2 Pro 16GB/512GB when graphics, memory bandwidth, four Thunderbolt ports or built-in USB-A matter more than single-core speed. Aim below its $950 median because the condition mix is broad and 16 of 21 observed offers came from eBay.

Buy the M6 if a new-machine warranty, newer networking or the lower-risk path matters enough to cover a $140-$149 premium. Wait for independent measurements if performance is the reason for paying it.

Shopping the current Pro tier instead? Our M4 versus M4 Pro comparison answers whether the 2024 Pro chip is worth roughly $925 more than the base M4, and prices both against the $1,699 M5 Pro.

Every secondhand figure here is an asking price, not a completed sale. The panels also combine used, open-box and refurbished stock. Nineteen of the 21 M2 Pro configurations were inferred from listing text rather than a verified part number, so confirm 10 CPU cores, 16 GPU cores, 16GB and 512GB in the system report before money changes hands. The used Mac buying checklist covers the rest of the inspection.
