Apple M5 Ultra and M6 Silicon Explained: 2nm Tech, Quad-Die Chips Promise Macs Massive AI Muscle - PCMag Middle East
Summary
Apple announced the M6 and M5 Ultra chips on August 26, 2026, for the new Mac mini and Mac Studio. The M6 is Apple's first chip built on a 2nm process, featuring a new 12-core CPU with two super cores. The M5 Ultra uses a quad-die architecture to deliver up to a 36-core CPU and an 80-core GPU. These chips prioritize on-device AI with up to four-times faster AI performance than the M1. The new Mac mini starts at $899, while the Mac Studio with the M5 Ultra begins at $5,499.
Key points
- The M6 chip uses a 2nm manufacturing process and a new 12-core CPU with two super cores.
- The M5 Ultra features a quad-die architecture with over 4.4TBps of inter-die bandwidth.
- The M5 Ultra supports up to 512GB of unified memory with 1.2TBps of bandwidth.
- The new Mac mini starts at $899 and the Mac Studio with M5 Ultra at $5,499.
- macOS 27 Golden Gate introduces a new integrated Siri AI assistant and Core AI framework.
