In a bit of a late-August surprise while the world awaits word on the next generation of iPhones, on Tuesday Apple announced two new processors, the M5 Ultra and M6, which help power new iterations of its Mac Studio and Mac mini desktop computers. Both models are available to pre-order now and will ship on September 22 and will run macOS 27 Golden Gate.
Bridging the generations
The M6 chip kicks off Apple’s next chip generation, and is its first based on a 2-nanometer production process. It’s also got the first 12-core CPU in Apple’s base M-series chip line, up from 10 cores in the M4 and M5 generations.
Those CPU cores are in an interesting configuration: The M6 is the first Apple chip to mix all three of its CPU core types. The chip has six efficiency cores, four performance cores, and two super cores. According to Apple, each core design is focused on a different primary task: efficiency cores are meant to sip power (useful when running simple background tasks); performance cores are optimized for complex, multi-threaded jobs; and super cores were created to offer the highest possible single-threaded performance.
Apple claims that this design results in record-setting single-threaded performance and up to 1.2x speed improvements over the M5 chip. The M6 also offers a dual 16-core Neural Engine, for on-device AI performance. Memory bandwidth peaks at 170GB/s, 10 percent faster than the M5.
