Apple's M6 iMac is no longer a preorder. The $1,499 all-in-one started arriving at customers' doors and in Apple Store locations on Friday, November 6, in 35 countries and regions, ten days after Apple announced it on October 27. The headline is not the seven colors. It is a Dual 16-core Neural Engine, up to 170GB/s of memory bandwidth, and Apple's claim that on-device AI workloads run up to 5x faster than on the M4 iMac. That combination turns a routine spec refresh into Apple's most direct pitch yet for local inference on a consumer desktop.
Pricing splits into two configurations. The 10-core CPU and 10-core GPU model starts at $1,499, or $1,449 for education buyers. The 12-core CPU and 12-core GPU model starts at $1,699, or $1,599 with education savings. Apple is also pushing an Apple Upgrade lease from $28.99 per month in the U.S.
That price band is why the AI claims matter. A $1,499 desktop that can hold a model in unified memory and answer prompts locally is a different sales pitch from a $1,499 desktop that merely runs Excel faster. Apple leans into that framing directly, citing LM Studio prompt processing as its benchmark of choice rather than a synthetic integer score.
The Spec Sheet in One Screen
Apple's own summary of what changed generation over generation is compact enough to read as a checklist:
- Up to a 12-core CPU, two more cores than the M4 iMac, which Apple says delivers the world's fastest single-threaded CPU performance.
- Up to a 12-core GPU with Neural Accelerators in every core, up to 2x faster graphics than M4, and 2x ray tracing performance.
- A Dual 16-core Neural Engine, which Apple describes as up to 2x the AI compute of the previous generation.
- Up to 170GB/s of memory bandwidth, with Wi-Fi 7, Bluetooth 6, and 2.5Gb Ethernet.
- Up to four Thunderbolt 4 ports, support for two 6K external displays, and SSD reads and writes up to 2x faster.
- The same 24-inch 4.5K Retina display at 500 nits, in blue, green, pink, yellow, purple, orange, and silver.
The CPU is the same core complex Apple detailed in August: two super cores, four performance cores, and six efficiency cores, up from ten cores on M5. That is a modest headcount change with an outsized effect on single-thread work, which is where most interactive development and agent tooling still spends its time.
Where the AI Numbers Get Interesting
The on-device AI figure is up to 5x versus M4, and up to 12x for prompt processing in LM Studio versus an M1 iMac. Both are first-party numbers measured on specific workloads, so treat them as direction rather than law. Still, the shape of the claim is instructive: prompt processing is a prefill-bound task, which is why memory bandwidth, not TOPS, is the number to watch when you are stuffing a long context into a local model.
Apple lists up to 170GB/s of bandwidth against 120GB/s on the M4 iMac, and a Dual 16-core Neural Engine that it says doubles AI compute. For anyone running a 7B or 14B parameter model locally, that pairing decides whether the model feels instant or merely usable, and how much of a codebase you can keep resident without falling back to a cloud endpoint.
The upgrade pitch aimed at the installed base is blunter: up to 18x faster than the most popular Intel-based iMac, and up to 2.5x faster than an M1 iMac in apps like Excel. The 18x figure is a retention statistic dressed as a performance statistic, and it tells you exactly who Apple believes is still sitting on a 2019 desktop.
What Apple Did Not Ship
There is no M6 Pro or M6 Max here, and no redesign. The chassis, the panel, the accessories, and the color lineup all carry over. Apple's pro-tier silicon story has moved to the M7 roadmap, which the company has framed around AI rather than raw clocks, leaving the standard M6 to cover the mainstream Mac lineup on its own.
Connectivity is the underrated part of the refresh. Wi-Fi 7, Bluetooth 6, 2.5Gb Ethernet, four Thunderbolt 4 ports, two 6K external displays, and SSDs that read and write twice as fast. None of it is glamorous, but all of it shortens the loop between a downloaded model, its weights, and the screen, which is precisely the workflow Apple is now selling.
Software carries the rest. macOS 27 brings the next generation of Apple Intelligence and Siri AI, including Visual Intelligence on a keyboard shortcut and writing tools that mirror a user's tone. Apple also name-checks LM Studio Bionic and Topaz Studio as optimized AI apps, a quiet admission that the serious local inference crowd does not live inside first-party software.
Who should buy: Intel iMac owners, small studios running local models, and anyone who wants a family machine that doubles as a private inference box. Who should wait: M4 iMac owners, anyone who needs M6 Pro-class GPU throughput, and buyers expecting a new design. Independent benchmarks should land within days, and they will decide whether the 5x claim is a floor or a ceiling. Until then, the takeaway is structural: Apple has stopped selling the iMac on thinness and started selling it on tokens per second.
