Owners of M4 Macs may feel the temptation to upgrade to the M6 Mac mini, MacBook Pro, or iMac. Here's what to expect with the jump to Apple's newest silicon. In August 2026, Apple introduced the M6 as its new entry-level chip, as well as the M6 generation itself. Brought out with the Mac mini, the M6 was framed by Apple as a way to benefit more from AI, with changes that made it an ideal chip for machine learning workloads. The introduction took place just over two years after Apple launched its first M4 chip in the iPad Pro. The M6 is also a two-generation jump for some models, such as the Mac mini, which skipped the base M5 chip completely.
With Apple bringing out more hardware using M6, more consumers are going to look at the new hardware and seriously consider upgrading from their M4 equivalents. This is the breakdown of what Apple's M6 chip provides, and how it is different from the M4. The M6 and M4 are made by Apple's usual chip foundry partner, TSMC. However, they are made using two different processes. The M4 was made using a 3-nanometer process, while the M6 uses a 2-nanometer version. There are usually quite a few benefits for a so-called die shrink, with the first being density. You can fit more transistors in a smaller process level than a larger one, simply because everything is much smaller. When it comes to transistors, TSMC was able to squeeze 46 billion onto the M6 die. The M4, meanwhile, has just over half that figure at 28 billion transistors.
The more transistors on a chip, the more potential calculations and processes it can perform. The smaller dies can also get advantages in other areas, such as requiring less power for processing. Heat dissipation is also improved on smaller processes. The die shrink means that the M6 can run cooler and with less energy than the M4 on comparable workloads.
