I’ve spent the last week with Apple’s new iMac Pro, and in most ways it’s just a faster Mac. It's the first pro Mac desktop in over three years and the fastest Mac yet made, granted, but still entirely familiar. And yet in many ways—some noticeable, some entirely invisible—this new Mac is completely different from all past Mac models.
The iMac Pro may be an outlier today, but in the future we’ll probably look back on it as the start of a new era for the Mac, all because of the Apple-built T2 chip it carries inside. Here’s how the T2 makes this iMac Pro unlike all other Macs.
The power behind the throne
The T2 processor isn’t doing the heavy lifting in the iMac Pro—that’s the Intel Xeon processor with between 8 and 14 processor cores. The T2 is the brain behind that brain, running the subsystems of the iMac Pro from a single piece of Apple-built silicon. The result is a simplified internal design that doesn’t require multiple components from multiple manufacturers.
