Apple’s M1 Ultra is two M1 Max chips stitched together

Apple announced the new M1 Ultra chip during the Apple Spring Event 2022, building on top of the M1 Pro and M1 Max introduced in the MacBook Pro late last year.

The chip essentially combines multiple M1 dies to create a more powerful processor, and Apple says it’s built for “extreme levels of performance.” Apple says that the M1 Max has a secret interconnect and that the M1 Ultra utilizes this interconnect to link two processors together.

The chip supports up to 128GB of memory, and it features a 20-core CPU and 64-core GPU. Apple says the chip is nearly eight times as fast as the base M1, and it has twice the number of processing units as the M1 Max.

Like previous M1 chips, the M1 Ultra is targeted at power efficiency. Apple says the GPU uses only a third of the power of a common GPU and is up to 90% more efficient than a leading 16-core desktop CPU.

We were massively impressed by the M1 Max inside the MacBook Pro, and Apple looks to be furthering that with the M1 Ultra. It’s still built on the 5nm process and with the same architecture as the M1; however, it seems to offer significantly more processing power.

Based on Apple’s renders (pictured below), the M1 Ultra looks like two M1 Max chips connected together. The specs back that up, too. The M1 Ultra doubles the CPU cores to 20 and GPU cores to 64, and it comes with twice as much memory bandwidth.

Apple is introducing the M1 Ultra with the new Mac Studio, which is essentially a souped-up version of the Mac Mini. The new machine is 3.8x faster than an iMac and 90% faster than a Mac Pro with an Intel Xeon processor, according to Apple.

Short of the 24-inch iMac and the M1 Mac Mini, this is the first proper desktop with Apple silicon. And it’s the first desktop to offer a high-end Apple chip for creative professionals and peak performance seekers.

Like previous M1 chips, the M1 Ultra comes with a combination of performance and efficiency cores. There’s a greater focus on performance cores, with 16 of the 20 CPU cores dedicated to performance and only four dedicated to efficiency. This is a far cry from Intel’s Alder Lake processors with their hybrid architecture, which focus more on the efficiency cores.

For the GPU, Apple says the M1 Ultra can match the performance of the “most powerful” discrete GPU while only using one-third of the power. Apple didn’t name the GPU during the event, so we’ll need to wait to see how the M1 Ultra stacks up once it’s here.

In addition to the M1 Ultra, Apple announced the iPhone SE and Studio Display during its spring event.

Apple’s M3 Max appears to keep up with Intel’s top desktop CPU
Apple revealing the M3 Max processor.

The first benchmarks of Apple's M3 Max processor just leaked, and it looks like it's going to be one speedy chip. Found in the new 16-inch MacBook Pro, the M3 Max pushes the capabilities of Apple silicon to new heights -- so much so that it can keep up with Intel's best desktop processor, all the while consuming far less power.

The exciting results come from a Geekbench 6 test. The chip listed under Apple M3 Max scored 2,943 in single-core and 21,084 in multi-core tests, respectively. Those are numbers that used to be pretty unreachable for a thin and light laptop just a couple of years ago, but they're comparable to Apple's M2 Ultra found in the latest Mac Pro (21,182 multi-core) and Mac Studio (21.316 multi-core).

Apple has everything it needs to dominate gaming — except games

Apple is finally hitting its stride with gaming. The company today announced the new M3 family of chips during its "Scary Fast" event, and they pack a redesigned GPU that adds some much-needed features for gaming in 2023. There's just one problem -- you can't play a ton of games on Mac.

There are some great games available on Mac -- just check out our list of the best Mac games -- but the big hurdle for Apple has always been broad game support. With the release of M3, along with some recent developments to porting games from Windows to Mac, Apple has a chance to make its gaming ambitions a reality. But all of that effort won't matter until we see games releasing on the platform alongside PC and consoles.

The M3 is the most important chip Apple has ever made
Apple's M3 chip family.

Macs with Apple silicon were a revelation when they launched three years ago, but we haven't seen Apple demonstrate how it will carry that idea forward since then. We saw the M2 release and the middling performance improvements that came with it, but the M3, announced during Apple's "Scary Fast" event, is the most important chip Apple has ever designed for Macs.

Although it carries the branding of the third generation of Apple silicon, it's really the second true generation. There's a lot riding on this release for Apple to prove that it can sustain its own silicon in Macs, and M3 is arriving at a time when there's fierce competition on all sides.
