M1 Ultra, M1 Pro, M1 Max and M1: Apple Mac Chips Compared

M1 Ultra, M1 Pro, M1 Max and M1: Apple Mac Chips Compared

Announced at Apple‘s “Peek Performance” event in March was another high-powered member of the M1 homegrown chip line, debuting in a shiny new Mac Studio micro desktop system. Along with the rest of the company’s M1 chip line, the M1, M1 Pro and M1 Max, the new M1 Ultra once again raises the performance level. It also hints at how Apple can scale its hybrid chip line to accommodate a Mac Pro-level system — the lone remaining Intel-based model — to complete its two-year plan to transition its system processors completely in-house. Rumors of a new M2 chip line debuting at WWDC 2022 on June 6 have also circulated, though aside from “more cores,” we don’t know anything about potential changes to the GPU or internal architecture.

Intel introduced its own hybrid (Alder Lake) 12th-gen desktop and mobile chips in late 2021. Thanks to the myriad possible combinations of performance and efficiency cores, plus GPU cores (execution units), choosing between those chips is nothing less than confusing.

Since Apple has fewer partners to please — just itself, actually — it doesn’t have Intel’s need to produce an overwhelming number of variations to allow for desktop and laptop systems to be priced differently. Still, Apple can be just as confusing because of the distinct CPU and GPU cores in chips that fall under the same name.

For instance, there are two versions of the M1 Pro, one with eight CPU cores and 14 GPU cores, and another with 10 CPU cores and 16 GPU cores. There are also two versions of the M1 Max. 

The M1 Max and M1 Pro clearly differ in terms of peak performance, with the M1 Max doubling some important contributors to theoretical performance, notably the number of hardware ProRes accelerators, which are extremely important for pro video editing. The M1 Max also doubles the bandwidth for some internal interfaces, like that between memory and the processor. Those won’t necessarily “double” the performance delivered in real-world use, though. 

Apple M1 vs. M1 Pro vs. M1 Max vs. M1 Ultra



Apple M1 Apple M1 Pro Apple M1 Max Apple M1 Ultra
Total CPU cores 8 8 or 10 10 20
Performance cores 4 6 or 8 8 16
Efficiency cores 4 2 2 4
GPU cores 7 or 8 14 or 16 24 or 32 48 or 64
Neural engine cores 16 16 16 32
Maximum memory supported (UMA) 16GB 32GB 64GB 128GB

Apple took a somewhat blunt approach for the M1 Ultra, simply tying together two M1 Max (24 GPU core) processors and chipsets via a 2.5TB/sec direct connection, branded “UltraFusion,” rather than having to traverse the slower system bus. So it has two of everything, such as two Thunderbolt controllers and two memory controllers. That’s why the Mac Studio with the M1 Ultra has more Thunderbolt ports and can accommodate twice the memory of its M1 Max-based counterpart. It’s basically a dual-processor system. There are even two versions for both GPU variations of the M1 Max.

The Ultra is two processors and two chipsets tied together.

And that’s likely to make it bigger and hotter. For instance, the chip is easier to scale to larger numbers of CPU and GPU cores, which will be necessary for whatever Mac Pro refresh is in the cards, but it seems cumbersome to have multiple supporting chipsets as well. The Mac Studio with the M1 Ultra has a huge heatsink and fan system necessary to cool it. Though it likely doesn’t deliver twice the performance of the M1 Max, we still don’t know how performance scales with the number of processors. This will be its first test.

One thing about the M1 implementations thus far is that there is no mention of discrete graphics support. Apple has claimed the Ultra delivers better graphics performance than the AMD cards in the Mac Pro, possibly teeing up a future reveal that it won’t have any — or that it has created a discrete graphics solution based on its GPU technology. Unlike the Mac Studio, which can’t be upgraded, the Mac Pro has to be upgradable. That’s one of the points of it.

Keep in mind that Apple’s unified memory architecture means that memory is shared by the GPU and CPU. That’s definitely better for performance, since it makes both processing and graphics tasks faster at passing data between each other.

Nothing announces official launch date for new Ear (stick) AirPods alternatives

Nothing announces official launch date for new Ear (stick) AirPods alternatives

True to form, Nothing has just announced the full reveal date for its upcoming audio product, Ear (stick). 

So, an announcement about an announcement. You’ve got to hand it to Carl Pei’s marketing department, they never miss a trick.

What we’re saying is that although we still have ‘nothing’ conclusive about the features, pricing or release date for the Ear (stick) except an image of another model holding them (and we’ve seen plenty of those traipsing down the catwalk recently), we do have a date – the day when we’ll be granted official access to this information. 

That day is October 26. Nothing assures us that on this day we’ll be able to find out everything, including pricing and product specifications, during the online Ear (stick) Reveal, at 3PM BST (which is 10AM ET, or 1AM on Wednesday if you’re in Sydney, Australia) on nothing.tech (opens in new tab)

Any further information? A little. Nothing calls the Ear (stick), which is now the product’s official name, “the next generation of Nothing sound technology”, and its “most advanced audio product yet”. 

But that’s not all! Apparently, Ear (stick) are “half in-ear true wireless earbuds that balance supreme comfort with exceptional sound, made not to be felt when in use. They’re feather-light with an ergonomic design that’s moulded to your ears. Delivered in a unique charging case, inspired by classic cosmetic silhouettes, and compactly formed to simply glide into pockets.” 

Opinion: I need more than a lipstick-style case

It’s no secret that I want Nothing’s earbuds to succeed in world dominated by AirPods; who doesn’t love a plucky, eccentric underdog? 

But in order to become some of the best true wireless earbuds on the market, there is room for improvement over the Nothing Ear 1, the company’s inaugural earbuds. 

Aside from this official ‘news’ from Nothing, leaked images and videos of the Ear (stick) have been springing up all over the internet (thank you, developer Kuba Wojciechowski) and they depict earbuds that look largely unchanged, which is a shame. 

For me, the focus needs to shift from gimmicks such as a cylindrical case with a red section at the end which twists up like a lipstick. Don’t get me wrong, I love a bit of theater, but only if the sound coming from the earbuds themselves is top dog. 

As the natural companions for the Nothing Phone 1, it makes sense for the Ear (stick) to take a place similar to that of Apple’s AirPods 3, where the flagship Ear (1) sit alongside the AirPods Pro 2 as a flagship offering. 

See, that lipstick case shape likely will not support wireless charging. That and the rumored lack of ANC means the Ear (stick) is probably arriving as the more affordable option in Nothing’s ouevre. 

For now, we sit tight until October 26.

YouTube could make 4K videos exclusive to Premium subscribers

You might soon have to buy YouTube Premium to watch 4K YouTube videos, a new user test suggests.

According to a Reddit thread (opens in new tab) highlighted on Twitter by leaker Alvin (opens in new tab), several non-Premium YouTube users have reported seeing 4K resolution (and higher) video options limited to YouTube Premium subscribers on their iOS devices. For these individuals, videos are currently only available to stream in up to 1440p (QHD) resolution.

The apparent experiment only seems to be affecting a handful of YouTube users for now, but it suggests owner Google is toying with the idea of implementing a site-wide paywall for access to high-quality video in the future.

So, after testing up to 12 ads on YouTube for non-Premium users, now some users reported that they also have to get a Premium account just to watch videos in 4K. pic.twitter.com/jJodoAxeDpOctober 1, 2022

It’s no secret that Google has been searching for new ways to monetize its YouTube platform in recent months. In September, the company introduced five unskippable ads for some YouTube users as part of a separate test – an unexpected development that, naturally, didn’t go down well with much of the YouTube community. 

A resolution paywall seems a more palatable approach from Google. While annoying, the change isn’t likely to provoke the same level of ire from non-paying YouTube users as excessive ads, given that many smartphones still max out at QHD resolution anyway. 

Of course, if it encourages those who do care about high-resolution viewing to invest in the platform’s Premium subscription package, it may also be more lucrative for Google. After all, YouTube Premium, which offers ad-free viewing, background playback and the ability to download videos for offline use, currently costs $11.99 / £11.99 / AU$14.99 per month.

Suffice to say, the subscription service hasn’t taken off in quite the way Google would’ve hoped since its launch in 2014. Only around 50 million users are currently signed up to YouTube Premium, while something close to 2 billion people actively use YouTube on a monthly basis. 

Might the addition of 4K video into Premium’s perk package bump up that number? Only time will tell. We’ll be keeping an eye on our own YouTube account to see whether this resolution paywall becomes permanent in the coming months.
