Apple’s M6 iMac Claims Fivefold AI Gains, Starting at $1,499

Apple’s new M6 iMac opens for preorder on October 28 at $1,499, with the company claiming up to five times faster on-device AI prompt processing than the iMac M4 and 12 times the speed of M1.

Apple also describes the release as a “huge leap” in AI performance. The claim rests on more cores, higher performance per core and new Neural Accelerators (hardware blocks for neural-network work) in each core. Apple says those additions deliver a “major boost” in general performance and AI capability.

The launch follows the unveiling of a new iPad mini the previous day and continues Apple’s staggered “Pro and Tell” release schedule. The iMac sits at the entry level of Apple’s desktop range, although the M6 first appeared in the Mac mini and Mac Studio.

Apple’s broader product sequence makes the M6 iMac a bridge between its enthusiast desktops and its mainstream all-in-one system. The processor arrives first in the mini and Studio, then reaches the $1,499 model. That rollout extends the same on-device AI pitch across three Mac form factors without changing the iMac’s display.

What changes in Apple’s M6 chip?

The top M6 configuration reaches a 12-core CPU (central processing unit) and 12-core GPU (graphics processing unit). It also carries a Dual 16-core Neural Engine, the hardware subsystem Apple uses for neural-network computations. According to Apple, the chip has more total cores and more performance per core than the M4.

Apple credits new Neural Accelerators in each core, alongside the added core count, for faster AI work. The company’s “major boost” language therefore combines general compute gains with a larger Neural Engine and dedicated hardware inside individual cores.

Apple specifies faster 170GB/s memory bandwidth for the M6 iMac. The company says the processor and bandwidth together make the machine twice as fast for graphics performance as the previous M4 model. Apple links that gain to intensive tasks such as photo editing and gaming.

Models start with 16GB of unified memory, meaning memory shared by the CPU and GPU. Apple also offers 24GB and 32GB options. The announcement gives no separate prices for those higher-memory configurations.

How large are the performance gains?

Apple’s productivity comparison is more modest than its AI headline. The company says the M6 iMac runs Microsoft Excel tasks up to 50 percent faster than the iMac M4. Against the older M1, Apple puts the gain at 2.5 times.

The M4 serves as the direct generation-to-generation benchmark, while the M1 provides the longer-term comparison. The announcement gives no common test settings or results beyond the products and workloads Apple names.

Apple also says the M6 iMac delivers up to double the GPU performance of the M4. The company associates that capability with demanding work such as photo editing and video editing. For gaming, Apple promises up to double the performance for ray tracing, a rendering method for producing illuminated graphics.

Every cited comparison comes from Apple; the announcement provides no independent application-level results. The figures’ practical value depends on whether buyers use Excel, creative applications, games or local AI models heavily. The processor claims cover distinct workloads rather than one aggregate score.

For buyers, the comparison set serves two purposes. M1 marks the performance distance across several hardware generations, while M4 provides the direct purchase comparison. Neither baseline substitutes for a test on the application a buyer actually uses.

Apple makes its most pronounced claim in AI. For on-device, or local, prompt processing in LM Studio, the application used in Apple’s comparison, the company says the M6 iMac runs up to five times faster than the M4. Against the M1, Apple claims 12 times the speed.

The result concerns prompt processing rather than every AI workload. Apple provides no wider benchmark set for the fivefold and 12-times figures. That limits how directly they translate into broader AI performance.

What does the new Siri AI actually do?

Like the Mac mini and Mac Studio, Apple centers the iMac launch on AI rather than a display refresh. The M6 iMac runs macOS 27 and the next generation of Apple Intelligence with Siri AI. Apple calls the assistant “profoundly more capable” than the old Siri.

The listed functions include asking questions and finding information in emails and photos. Apple also embeds Siri AI in Spotlight, its system search feature. According to Apple, users can use Spotlight to find answers on any topic and then ask follow-up questions.

For buyers, the pitch shifts the iMac’s value proposition toward work performed on the machine itself. The strongest supporting number is the local prompt-processing result, not a broader set of independent AI benchmarks. Apple provides no accuracy measures or comparative test results for the new assistant.

Apple also does not define the boundaries of “any topic.” Those omissions leave the practical scope of Siri AI less clear than the fivefold prompt-processing figure. The software promise is substantial, but the announcement supplies more speed data than evidence about output quality.

What stays unchanged on the iMac?

The 24-inch 4.5K Retina display remains unchanged from the preceding iMac. Apple specifies 500 nits of brightness, a measure of light output, and P3 wide color, which covers a broad color gamut. The display therefore provides no visible generational marker for the M6 upgrade.

Apple has not introduced a new 27-inch iMac, and the larger model remains absent from this release. That omission reinforces the product’s role as a performance-led update to the entry-level desktop rather than a redesign of Apple’s all-in-one range.

Which ports and connections come with it?

Apple adds Wi-Fi 7 and Bluetooth 6 to the iMac. Ethernet now supports 2.5Gb, or 2.5 gigabits per second, providing 250 percent more speed than before, according to Apple. Those upgrades modernize the machine’s wired and wireless connections.

The M6 iMac does not receive the latest Mac Studio’s two-times-faster Thunderbolt 5 connections. It supports Thunderbolt 4 instead, a high-speed connection standard that Apple leaves below the Studio’s newest option.

That difference leaves native Thunderbolt 5 exclusive to the Mac Studio in the compared lineup, even though the M6 also serves the Mac mini and Mac Studio. The iMac compensates with faster Ethernet, newer wireless standards and support for up to two external 6K displays.

The port ceiling therefore keeps the entry-level iMac below the Studio for users who need Thunderbolt 5. The M6 closes much of the processor gap, but Apple retains a clear hardware distinction between its desktop tiers.

What do the configurations cost?

Apple retains a 12MP Center Stage camera, offers seven colors and includes color-matched accessories. Touch ID provides fingerprint authentication. Those features remain secondary to the company’s published performance pitch, which centers on processor cores, memory bandwidth and local AI throughput.

Apple publishes two configurations:

• $1,499: 10-core CPU and 16GB of RAM.
• $1,699: 12-core CPU, 12-core GPU and 16GB of memory.

Apple also lists 24GB and 32GB unified-memory options. It does not publish separate prices for those configurations in the announcement. Preorders begin on October 28.

The $200 gap separates the listed 10-core CPU configuration from the 12-core CPU and 12-core GPU option, while memory remains at 16GB. Apple does not quantify how much of its Excel, graphics or LM Studio advantage comes from the higher configuration.

Those figures keep processor specifications separate from measured application performance. Buyers can compare core counts directly, but Apple’s workload claims still require testing on the applications and local models they intend to run.

The near-term test is whether independent tests reproduce Apple’s fivefold M4 prompt-processing claim and twice-as-fast graphics result on ordinary workloads. Until then, the M6 iMac’s strongest case rests on higher core counts, 170GB/s bandwidth and newer connectivity, starting at $1,499. Its clearest concessions are the unchanged display and lack of Thunderbolt 5.
