Apple’s M6 pitch leans hard on AI. The company says the chip handles LLM prompt processing up to 13 times faster than the M1 MacBook Pro and 1.3 times faster than the M5, with up to 25% faster AI workloads overall. The Register reports a dual 16-core Neural Engine, and TechCrunch notes Neural Accelerators built into every core. On paper, Apple is building a local-inference machine.

Then you look at the memory, and the paper gets thin.

The spec that matters for local models

The 14-inch MacBook Pro starts at 16GB of unified memory and tops out at 32GB. TechCrunch lists bandwidth as up to 170GB/s, up from 153GB/s on the M5. The Register adds a detail that changes how that number reads: the base 16GB model gets 153GB/s. You only get 170GB/s at 24GB or 32GB.

So the $1,999 entry machine has the same memory bandwidth as the M5 it replaces. Apple’s headline AI figure is about prompt processing, which leans on raw compute and benefits from the extra cores. Generating tokens, the part you actually sit and wait for, depends much more on how fast weights move out of memory. A faster chip feeding from the same pipe won’t make chat replies stream noticeably faster.

The 32GB ceiling is the bigger problem. That’s enough for small and mid-sized open-weight models with aggressive quantization, plus a browser and an IDE if you’re careful. It isn’t enough for the larger models people buy a Pro laptop to run. If local AI is your reason for buying, the 16GB base model is the wrong machine, and even the maxed-out 14-inch is a compromise. Spend for 32GB or skip this refresh.

What you do get

For everyone else, this is a competent mid-cycle refresh. The M6 is built on TSMC’s 2nm process with 12 CPU cores and 12 GPU cores, and Apple claims up to 30% faster graphics than the M5. Battery life stays at 24 hours. Price stays at $1,999, which per The Register buys 16GB of memory and 1TB of storage. Wi-Fi 7 and Bluetooth 6 finally arrive on the 14-inch model.

The chassis is unchanged. Same mini-LED display, same keyboard, same ports: HDMI, MagSafe 3, an SDXC slot, a headphone jack, and three Thunderbolt 4 ports. Fast charging hits 50% in 30 minutes with a high-wattage adapter. The camera is still 12 megapixels. If you own an M5 MacBook Pro, nothing here should make you upgrade.

The iMac is the better upgrade

The iMac skipped the M5 entirely, so its owners get the whole jump at once. Apple claims 1.5x faster productivity performance, 2x faster graphics, and up to 5x faster on-device AI compared with the M4 model. Some configurations add 2.5Gbps Ethernet alongside Wi-Fi 7 and Bluetooth 6. It still starts at $1,499, with a 24-inch 4.5K display, up to four Thunderbolt 4 ports, and seven colors.

That 5x AI figure is measured against a two-generation-old chip, which flatters it. Even so, someone replacing an M4 iMac will feel this upgrade more than someone replacing an M5 MacBook Pro.

Preorders for both open October 28, and they ship November 6. The M6 already showed up in the Mac mini in August, and the M5 is still in the MacBook Air. Apple hasn’t said when a 14-inch configuration with more than 32GB of memory will arrive.
