Apple's M6 iMac Keeps the Same Shell and Moves Two Chip Generations Ahead
Apple has announced an iMac refresh built on the M6 chip, starting at $1,499. The Verge reported the announcement on October 27, 2026, ahead of Apple's "Pro and Tell" event, which is scheduled for Wednesday.
The enclosure is largely unchanged from the previous model. The changes are inside. The base M6 iMac starts with a 10-core CPU and a 10-core GPU, compared with the 8-core CPU on the M4 iMac Apple introduced in October 2024. This refresh arrives two years after that overhaul. Apple skipped the M5 generation on iMac entirely, so the desktop moves directly from M4 to M6.
The M6 is Apple's first 2nm chip, meaning it is built on a newer manufacturing process with smaller transistor features, which generally improves efficiency and density. It includes a dual 16-core Neural Engine, the dedicated block that handles on-device AI tasks. Apple's August newsroom release introduced the M6 alongside the M5 Ultra and cited a 12-core CPU and 12-core GPU for the chip itself. The iMac's entry configurations are 10-core on both counts, so the top of the M6 range sits above what the base iMac ships with.
The M6 has already appeared in another desktop. In August, Apple launched the M6 with the Mac mini, paired with the M5 Pro. Apple's press release for that machine claimed up to 4x faster AI performance, 2x faster storage and graphics, and 40 percent faster CPU performance. The M6 iMac is the second Mac to adopt the chip.
The rest of the current Mac lineup was set earlier in 2026. In March, Apple introduced MacBook Pro models with M5 Pro and M5 Max chips, which the company said offer up to 24 hours of battery life, and a MacBook Air with M5. Both laptops include the N1 wireless networking chip, which enables Wi-Fi 7 and Bluetooth 6. The 14-inch MacBook Pro with M5 starts at $1,699 in the U.S., includes 1TB of storage as standard, and comes in space black and silver. In October 2025, Reuters reported, citing Bloomberg News, that Apple was preparing a redesigned MacBook Pro with a touch display for late 2026 or early 2027.
The broader context here is the split between chassis and silicon. The iMac's exterior has stayed the same while its processor has moved two generations. That puts the upgrade in the components that determine inference throughput, memory bandwidth and sustained performance under load. Buyers comparing an M4 iMac with an M6 one should look at core counts, Neural Engine capability and the M6 configuration options, not the case. Apple's wider M6 rollout, across the Mac mini and now the iMac, suggests the chip is being positioned as the common base for its desktop line.
In my view, the more useful question for professionals is what the 2nm process and the expanded on-device AI hardware make practical on a desk. Local inference, large local media and code workloads, and multi-app creative pipelines are all areas where a faster Neural Engine and a larger GPU change what can run without a round trip to a remote server. Those gains will show up in real workloads rather than in headline figures, and that is where the refresh will be judged.
