Apple Reveals M6 as First-Ever 2nm Chip

The useful part

Apple today announced the M6 chip, its first built using a 2-nanometer process and featuring a Dual 16-core Neural Engine. Apple says the 2nm process packs greater transistor density into a smaller die, contributing to the chip's overall gains in performance and power efficiency. The M6 chip features a larger, more powerful 12-core CPU, two more cores than the M5, made up of two super cores, four performance cores, and six efficiency cores.

How it works

• Apple says system frameworks can automatically use both engines at once, allowing applications to run AI models faster.
• Apple says the chip delivers the world's fastest single-threaded performance and up to 1.2x faster multithreaded performance than the M5, and up to 2.4x faster than the M1.
• The chip also features a 12-core GPU, with two more cores than the M5, with a Neural Accelerator built into each core.
• Apple says this delivers nearly a 30% increase in peak GPU compute for AI compared to the M5, and more than 8x compared to the ‌M1‌, resulting in faster prompt processing for on-device LLMs.
• The GPU also gains updates to the shader core architecture, Dynamic Caching, and hardware-accelerated ray tracing, along with a 50% increase in geometry rates for more complex graphics.

What to take from it

The chip supports up to 32GB of unified memory and up to 170GB/s of unified memory bandwidth, which is a 10% increase over M5 and 2.5x more than the ‌M1‌. The M6 debuts in the <a href="https://www.macrumors.com/2026/08/25/apple-an...
