Max Tech performed the first detailed teardown of the Apple Mac Studio, the most powerful Mac since Apple dumped Intel for processors in favor of its own silicon based around high-performance Arm chips built from the ground-up for its own software ecosystem. The M1 Ultra SoC powering the Mac Studio is its most striking piece of technology, with Apple attaching some very tall performance claims not just for its CPU compute performance, but also graphics rendering performance.

The M1 Ultra SoC is physically huge, with roughly similar package size to an AMD EPYC processor in the SP3 package. An integrated heatspreader (IHS) covers almost the entire topside of the package. Things get interesting under the hood. The M1 Ultra is a multi-chip module of two M1 Max dies connected on package using Apple UltraFusion, a coherent fabric interconnect that allows the various components of the two M1 Max dies to access memory controlled by the other die. Speaking of memory, The M1 Ultra features up to 128 GB of LPDDR5 memory that's on-package, This memory is used for the CPU, GPU, as well as the neural processor, and has a combined memory bandwidth of 800 GB/s. The M1 Ultra features up to 20 CPU cores, up to 32 Neural cores, and up to 64 GPU cores (8,192 programmable shaders).

Apple made some bold claims at the launch of its new Mac Studio computers when it came to the performance of the new systems and it looks like Apple was exaggerating those claims by quite some margin when it comes to the graphics performance. The first reviews of the new Mac Studio went live today and thanks to those reviews, despite the limited benchmarks that were performed on the new systems from Apple, that as so often Apple's performance metrics are still relying on the reality distortion field. Most of the publications that got their hands on the new systems focused on CPU benchmarks and there's no doubt the Ultra version of the M1 processor is a beast when used for things like video rendering and complex image manipulation, where it's butting heads with an AMD Ryzen Threadripper 3970X.

However, Apple's 64-core GPU isn't quite what the company claimed. In the presentation footnotes Apple provided details on the "highest-end discrete GPU" that they compared to, which was an NVIDIA GeForce RTX 3090. If we were to be kind to Apple, we would say that the company was slightly off target here, but it's actually not even remotely close. Tom's Guide tested the M1 Ultra SoC in Sid Meier's Civilization 6 and got a whopping 38.85 FPS at 1440p, which is beaten soundly by a Lenovo ThinkPad P1 Gen 4 with a GeForce RTX 3070 laptop GPU that scored 64.9 FPS at 4K. Likewise, The Verge decided to test the claims and had a system with an actual GeForce RTX 3090 in it and ran Shadow of the Tomb Raider and the PC managed 142 FPS at 1080p, with the M1 Ultra coming in quite far behind at 108 FPS. Moving up to 1440p the 3090 came in at 114 FPS, with the M1 still trailing behind, if not quite as badly at 96 FPS.

Less than 24 hours after Apple's launch event, the first Geekbench numbers for the new Apple M1 Ultra CPU are out and the numbers are interesting to say the least. For starters, the system the Geekbench numbers are from, is the top of the range 20 Core SKU with 128 GB of RAM. This helps us get some additional insight into Apple's new CPUs. As Apple didn't provide much in technical terms yesterday, nor on its website, we now know that the clock speed of the M1 Ultra is the same 3.2 GHz as the regular M1. It also appears that the CPU cache remains the same, even though Geekbench is only listing the cache of the efficiency cores for some reason.

Although Geekbench isn't a reliable cross-platform benchmark, we do at least get an idea of how the new SoC from Apple performs. The single core performance is more or less on par with the Apple M1 Max, but loses out quite easily to Intel's Alder Lake processors. However, once we move to the multi-threaded test, the M1 Ultra really shows what it's capable of. Surprisingly the performance scaling is almost linear with the double of performance CPU cores compared to the M1 Max, which suggests that Apple's multi-chip module design is extremely capable. The interesting thing will be to see how well this design scales for GPU intensive applications. Stepping outside of the Apple ecosystem, the M1 Ultra ends up somewhere around an AMD Ryzen Threadripper 3970X in terms of multi-core performance. Scaling over some of the detailed tests aren't somewhere between 80-90 percent depending on the particular test compared to the M1 Max, if we compare to the faster results on Geekbench, which is still quite impressive considering we're looking at two M1 Max CPUs that are technically glued together.

Apple yesterday announced its M1 Ultra processor. It is designed to be one of the most powerful solutions ever envisioned for desktop users, and it leverages some of the already existing technologies. Essentially, the M1 Ultra chip combines two monolithic dies containing M1 Max designs. They are stitched together to create one massive chip behaving in a rather exciting way. To pair the two M1 Max dies together, Apple has designed a package called UltraFusion, which is a die-to-die interposer with more than 10,000 signals. It provides 2.5 TB/s low latency inter-processor bandwidth and enables seamless sharing of information across two dies.

What is more interesting is that this approach, called multi-chip module (MCM) design philosophy, allows the software to view these two dies as a single, unified processor. Memory is shared across a vast pool of processor cache and system memory in a single package. This approach is software agnostic and allows hardware to function efficiently with loads of bandwidth. Apple notes that no additional developer optimization is required for the new processor, and the already-existing stack of applications for M1 Max works out-of-the-box. Talking about numbers, the M1 Ultra chip has a potential main memory bandwidth of 800 GB/s, with up to 128 GB of unified system memory. We are yet to see how this design behaves as the first Mac Studio units start shipping, so we have to wait for more tests to check these claims out.

Apple today introduced Mac Studio and Studio Display, an entirely new Mac desktop and display designed to give users everything they need to build the studio of their dreams. A breakthrough in personal computing, Mac Studio is powered by M1 Max and the new M1 Ultra, the world's most powerful chip for a personal computer. It is the first computer to deliver an unprecedented level of performance, an extensive array of connectivity and completely new capabilities, in an unbelievably compact design that sits within arm's reach on the desk.

With Mac Studio, users can do things that are not possible on any other desktop, such as rendering massive 3D environments and playing back 18 streams of ProRes video. Studio Display, the perfect complement to Mac Studio, also pairs beautifully with any Mac. It features an expansive 27-inch 5K Retina display, a 12MP Ultra Wide camera with Centre Stage, and a high-fidelity six-speaker sound system with Spatial Audio. Together, Mac Studio and Studio Display transform any workspace into a creative powerhouse. They join Apple's strongest, most powerful Mac line-up ever, and are available to order today, arriving to customers beginning Friday, 18 March.

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.
