苹果在加州库比蒂诺发布了新款Mac mini和Mac Studio桌面电脑，并同步推出M6与M5 Ultra两款全新芯片13。此次发布的时间，有来源记录为2026年8月25日1，另有来源表述为2025年8月25日4。苹果硅工程集团副总裁是Sri Santhanam1。新推出的M6芯片主要搭载于新款Mac mini，而被苹果称为“有史以来最强大”的M5 Ultra芯片则应用于Mac Studio123。
M6是苹果M系列首款采用2纳米制程的芯片1234。该芯片配备12核CPU，具体包含2个超级核心、4个性能核心和6个能效核心，核心数较前代M5的10核有所增加24。同时，M6搭载12核GPU，比M5多出2个核心4。在内存方面，M6支持最高32GB统一内存，提供高达170GB/s的内存带宽，较M5提升10%，较M1提升2.5倍14。性能表现上，M6具备全球领先的单线程性能，多线程性能较M5最高提升1.2倍，较M1最高提升2.4倍4。此外，M6引入双16核神经引擎以处理设备端AI工作负载，其峰值计算能力达到前代产品的2倍24。在AI场景下，其GPU峰值计算性能较M5提升近30%，较M1提升8倍以上；在处理复杂图形时，几何顶点处理率提升了50%，并大幅提升了端侧AI工作流的运行速度4。
面向3D渲染和运行前沿AI模型等任务的M5 Ultra采用了四die架构，是苹果专门针对AI工作负载优化的产品线中最强大的芯片123。该芯片最高支持36核CPU和80核GPU，并支持最高512GB的统一内存1。其统一内存带宽高达1.2TB/s，比M3 Ultra高出50%，从而大幅提升了AI计算和图形性能1。
Apple has unveiled the M6 and M5 Ultra chips, which will power the newly announced Mac mini and Mac Studio desktop computers 13. The announcement took place in Cupertino, California, on August 25 14. The M6 marks Apple's first chip built on a 2-nanometer process 1234.
The M6 features a 12-core CPU, comprising two super cores, four performance cores, and six efficiency cores, representing an increase from the 10 cores in the M5 24. It also includes a 12-core GPU, which has two more cores than its predecessor, and a dual 16-core Neural Engine designed for on-device AI workloads 124. In terms of memory, the M6 supports up to 32GB of unified memory with a bandwidth of 170GB/s, a 10% improvement over the M5 and a 2.5x increase over the M1 14. Performance-wise, the M6 delivers the world's fastest single-thread performance, with multi-thread performance up to 1.2x faster than the M5 and 2.4x faster than the M1 4. Additionally, its GPU peak compute for AI scenarios is nearly 30% higher than the M5 and over 8x higher than the M1, while the Neural Engine's peak compute is up to 2x that of the previous generation 4. The chip also improves complex graphics handling with a 50% increase in geometry vertex processing rate 4.
Alongside the M6, Apple introduced the M5 Ultra, which the company calls its "most powerful chip ever" 2. Utilizing a quad-die architecture, the M5 Ultra supports up to a 36-core CPU and an 80-core GPU 1. It is specifically optimized for demanding tasks such as 3D rendering and running frontier AI models 23. The M5 Ultra can accommodate up to 512GB of unified memory and delivers a 1.2TB/s memory bandwidth, which is 50% higher than that of the M3 Ultra 1. Sri Santhanam, Vice President of the Apple Silicon Engineering Group, was noted in the announcements regarding these new silicon developments 1.
