Apple Unveils M1 Ultra, the World's Most Powerful Chip For a Personal Computer
Apple today announced M1 Ultra, the next giant leap for Apple silicon and the Mac. Featuring UltraFusion — Apple's innovative packaging architecture that interconnects the die of two M1 Max chips to create a system on a chip (SoC) with unprecedented levels of performance and capabilities — M1 Ultra delivers breathtaking computing power to the new Mac Studio while maintaining industry-leading performance per watt.
The new SoC consists of 114 billion transistors, the most ever in a personal computer chip. M1 Ultra can be configured with up to 128 GB of high-bandwidth, low-latency unified memory that can be accessed by the 20-core CPU, 64-core GPU and 32-core Neural Engine, providing astonishing performance for developers compiling code, artists working in huge 3D environments that were previously impossible to render, and video professionals who can transcode video to ProRes up to 5.6x faster than with a 28-core Mac Pro with Afterburner."M1 Ultra is another game changer for Apple silicon that once again will shock the PC industry. By connecting two M1 Max die with our UltraFusion packaging architecture, we're able to scale Apple silicon to unprecedented new heights," said Johny Srouji, Apple's senior vice president of Hardware Technologies. "With its powerful CPU, massive GPU, incredible Neural Engine, ProRes hardware acceleration and huge amount of unified memory, M1 Ultra completes the M1 family as the world's most powerful and capable chip for a personal computer."
Groundbreaking UltraFusion Architecture
The foundation for M1 Ultra is the extremely powerful and power-efficient M1 Max. To build M1 Ultra, the die of two M1 Max are connected using UltraFusion, Apple's custom-built packaging architecture. The most common way to scale performance is to connect two chips through a motherboard, which typically brings significant trade-offs, including increased latency, reduced bandwidth and increased power consumption. However, Apple's innovative UltraFusion uses a silicon interposer that connects the chips across more than 10,000 signals, providing a massive 2.5 TB/s of low-latency, inter-processor bandwidth — more than 4x the bandwidth of the leading multi-chip interconnect technology. This enables M1 Ultra to behave and be recognised by software as one chip, so developers don't need to rewrite code to take advantage of its performance. There's never been anything like it.
Unprecedented Performance and Power Efficiency
M1 Ultra features an extraordinarily powerful 20-core CPU with 16 high-performance cores and four high-efficiency cores. It delivers 90 per cent higher multithreaded performance than the fastest available 16-core PC desktop chip in the same power envelope. Additionally, M1 Ultra reaches the PC chip's peak performance using 100 fewer watts. That astounding efficiency means less energy is consumed and fans run quietly, even as apps like Logic Pro rip through demanding workflows, such as processing massive amounts of virtual instruments, audio plug-ins and effects.
For the most graphics-intensive needs, like 3D rendering and complex image processing, M1 Ultra has a 64-core GPU — 8x the size of M1 — delivering faster performance than even the highest-end PC GPU available while using 200 fewer watts of power.
Apple's unified memory architecture has also scaled up with M1 Ultra. Memory bandwidth is increased to 800 GB/s, more than 10x the latest PC desktop chip, and M1 Ultra can be configured with 128 GB of unified memory. Compared with the most powerful PC graphics cards that max out at 48 GB, nothing comes close to M1 Ultra for graphics memory to support enormous GPU-intensive workloads like working with extreme 3D geometry and rendering massive scenes.
The 32-core Neural Engine in M1 Ultra runs up to 22 trillion operations per second, speeding through the most challenging machine learning tasks. And, with double the media engine capabilities of M1 Max, M1 Ultra offers unprecedented ProRes video encode and decode throughput. In fact, the new Mac Studio with M1 Ultra can play back up to 18 streams of 8K ProRes 422 video — a feat no other chip can accomplish. M1 Ultra also integrates custom Apple technologies, such as a display engine capable of driving multiple external displays, integrated Thunderbolt 4 controllers and best-in-class security, including Apple's latest Secure Enclave, hardware-verified secure boot and runtime anti-exploitation technologies.
macOS and Apps Scale Up to M1 Ultra
Deep integration between hardware and software has always been at the heart of the Mac experience. macOS Monterey has been designed for Apple silicon, taking advantage of M1 Ultra's huge increases in CPU, GPU and memory bandwidth. Developer technologies like Metal let apps take full advantage of the new chip, and optimisations in Core ML utilise the new 32-core Neural Engine, so machine learning models run faster than ever.
Users have access to the largest collection of apps ever for Mac, including iPhone and iPad apps that can now run on Mac, and Universal apps that unlock the full power of the M1 family of chips. Apps that have not yet been updated to Universal will run seamlessly with Apple's Rosetta 2 technology.
Another Leap Forward in the Transition to Apple Silicon
Apple has introduced Apple silicon to nearly every Mac in the current line-up, and each new chip — M1, M1 Pro, M1 Max and now M1 Ultra — unleashes amazing capabilities for the Mac. M1 Ultra completes the M1 family of chips, powering the all-new Mac Studio, a high-performance desktop system with a re-imagined compact design made possible by the industry-leading performance per watt of Apple silicon.
Apple Silicon and the Environment
The energy efficiency of Apple's custom silicon helps Mac Studio use less power over its lifetime. In fact, while delivering extraordinary performance, Mac Studio consumes up to 1,000 kilowatt-hours less energy than that of a high-end PC desktop over the course of a year.
Today, Apple is carbon-neutral for global corporate operations, and by 2030, plans to have net-zero climate impact across the entire business, which includes manufacturing supply chains and all product life cycles. This means that every chip Apple creates, from design to manufacturing, will be 100 per cent carbon-neutral.

Let me know when you've got something to back up your arguments beyond "I'm right and you're wrong!". What? The Mac Studio starts at $4000 and tops out at ~$9000. The prices were AFAIK in the presentation, were published immediately, and they updated their online storefront just after the announcement. Relatively normal workstation pricing, though of course Apple doesn't want to call it a workstation (it's just "for pros"). Definitely not "normal people" territory, but not much different from the specced-out MBPs they sell droves of.

Just a troll trolling :rolleyes: this is embarrassing Lex, please follow a link. Prices were announced and the ultra was up for pre-order during the presentation…
Of course on top of that you're denying the actual prowess of their current CPUs despite strong evidence to the contrary, all the while refusing to show evidence - or even arguments! - of your own. This is definitely not helping you seem less irrational, to put it mildly. As I said: you're reading what they're implying, not what they're saying. But if you'reso insistent on them lying, maybe bring an argument or two, or a source to the table? Make a point or two about how their performance is sub-par (based on third party reviews), and compare that to their actual statements? Uh... Again, this is just factually untrue. Did you even look? The M1 Max models start at $2000, with the Ultra models starting at $4000. Just another demonstration that you've got some sort of reality distortion filter going on here - the one Jobs is famed for creating, maybe? I don't see anyone here falling for the "Apple is so cool" stuff either, so... Can you please stop arguing against imagined opponents and try to address some of the glaring flaws in your logic that have been pointed out?
This was two days ago...
This was two minutes ago.
Maybe I'm not the most astute person in the world, but I don't see any prices on that PLACEHOLDER webpage, do you? Hmmm?
Who's embarrassing themselves? And I'm the one being called the troll and bully...

now:
Who am I kidding, Lex will probably never read a post from a lil old snowflake like me :( Props to @Valantar for their patience and hand-holding.
Honestly, Lex, stop being a raging dick. What did I say again?
Every option (not that there are that many: 48/64 CUs, RAM, storage, additional software) is selectable and has its price listed.
This was the case yesterday as well, and IIRC also shortly after the launch event.
It's also rather telling that the more we demonstrate how you're wrong, the more vague and empty your claims become. "Maybe you three should have taken a MUCH closer look" - at what? The website you claimed wasn't there? The pricing you claimed wasn't public? The SKUs you claimed weren't listed? The claims you said Apple made that they never did? The highly selective and carefully worded phrasing they used to hedge their statements, that you consistently misrepresent? Sorry, but the only person needing to look more closely here is you.
Some benchmarks have been posted for the M1Ultra and it performs well. However, Apple has yet to prove that it's the most powerful chip for a "personal computer".
So yeah, their marketing people deliberately lied. What. A. Shocker...
So, since we apparently have to do your sourcing for you: At around 30:55 in their presentation video, they say "It's the most powerful and capable chip, ever, for a personal computer." The context, which you claim to have such a good overview of: This is a summarizing statement after a discussion of its whole featureset: CPU, GPU, neural engine, encode/decode capabilities. In that context, this is a factually true statement. For it to be true does not at all require any of those constituent parts to be the most powerful, it only requires the combination of them to be more powerful than any similar combination. Which obviously has a lot of gray area - how do you weight the performance of each component in a comparison? - but which ultimately doesn't matter as they are miles ahead of everyone in this regard. They didn't say "most powerful CPU", "most powerful GPU", or anything like that. And nothing even remotely close to this combination exists in a single chip or package. The closest you might find would be something like Nvidia's automotive SoCs, though it looks to handily outperform those as well given their 12 relatively weak CPU cores (and much smaller die size). And those certainly aren't found in PCs.
So, to what you were saying about contextualizing their statements: how about you try doing that? I get that you're probably finding a lot of enjoyment in acting like this, but all you're achieving here is making yourself look incapable of formulating anything resembling an argument or discerning between the contents of a statement rather than its implications. Which ... you do you, I guess? But as I've said several times, at this point you're just helping Apple maintain their image as the cool, progressive, innovative company in contrast to the recalcitrant and conservative elitism of the PC industry. So: please don't be a PR tool for Apple. They neither need nor deserve it.
The bottom line is that regardless of if you agree with Apple's business practices or not, the M1 Ultra is a very interesting SoC as there really is nothing quite like it.
I read yesterday (at Tom's) that their interconnect seems to be based on CoWoS-S, i.e. a full silicon interposer and not some embedded bridge like EMIB or InFO. That just underscores how expensive this chip has to be to produce - not just two massive dice on a cutting-edge node, but a full-sized >860mm2 interposer in addition to the gargantuan package with its integrated LPDDR5 traces. Really makes me wonder what an even remotely comparable solution from AMD or Intel would cost - I would honestly expect it to be in the $10 000 range, given the tech, transistor counts, and hardware on the chip. It clearly doesn't compete with their top-end server CPUs that cost around that figure, but I can bet there are quite a few datacenter operators who would love a tightly integrated SoC like this - especially at these efficiency levels. Though there's no way they would settle for 128GB of RAM, obviously.
Two thoughts from this: It'll be interesting to see how Apple moves forward with the next generation of this, whether they stick with CoWoS-S or move to InFO. And I really hope AMD starts adopting InFO packaging across their lineup in the next few generations - given that IF on a Threadripper easily consumes 60-80W, it's reasonable to expect massive efficiency and performance gains just from such a move - though of course it'll also drastically increase thermal density by packing the CCDs tighter. Still, interesting times ahead, and I hope Apple has given Intel and AMD a bit of a kick in the rear with this.
