Apple Mac Studio (M3 Ultra): Two-minute review
Apple’s announcement of a new Mac Studio for 2025 took a lot of people by surprise. While many of us had assumed (correctly) that Apple was gearing up to announce new M4-powered MacBook Airs, few were expecting a new Mac Studio.
That’s understandable – by its very nature, the Mac Studio is a product that’s aimed at a more niche market than a thin and light laptop. Mac Studio devices are powerful, professional-grade computers that offer a level of performance that was once only found in Mac Pro desktop PCs, but built into a stylish and compact body that looks like a super-sized (yet still small) Mac mini.
The latest Mac Studio continues that tradition. The design keeps the iconic (and technically impressive, considering the hardware) compact look of previous Mac Studios, with dimensions of 3.7 x 7.7 x 7.7 inches (9.5 x 19.7 x 19.7cm) and a weight starting at 6.1lbs / 2.74kg. It’s a device that would look at home in any modern office or studio, and its size means it can be easily installed, and moved, wherever and whenever you want.
You are, however, missing out on the modular and upgradable nature of desktop PCs. You won’t be able to swap out the GPU or increase the internal storage in a few year’s time – two upgrades which are relatively simple with traditional PCs.
That said, for many people one of the upsides of buying a Mac is that they don’t need to fiddle around with internal components, and a lack of upgradability is a small price to pay for a compact device that’s well-built and works dependably. And, depending on the configuration options you choose when buying your Mac Studio, it’s unlikely that you’ll need to upgrade for a long, long time.
The new Mac Studio comes with a choice of two chips – one that was expected, and one that has come as quite a surprise.
The base model of the new Mac Studio features the M4 Max chip – the same chip that debuted late last year in the 14-inch and 16-inch MacBook Pros. There’s no option to have the standard M4 or M4 Pro chips, which is in line with Apple’s pitching the Mac Studio at power users and professionals who need the very highest levels of performance. If your requirements (and budget – I’ll get to prices in a moment) are more modest, then the aforementioned MacBook Pros will be better picks; or if you want a desktop PC, then the brilliant Mac mini from last year will do the trick, and can be configured with either an M4 or M4 Pro chip.
According to Apple, the Mac Studio with M4 Max offers 1.6x faster image processing in Adobe Photoshop compared to the Mac Studio with M1 Max, and 2.1x faster code compilation in Xcode. Video transcoding in the Compressor app is claimed to be 1.2x faster, and video processing in Topaz Video AI 1.6x faster.
While any speed increase that makes workloads faster is welcome, those aren’t mind-blowing numbers, so most people using the now three-year-old Mac Studio (M1 Max) won’t feel any pressing need to upgrade to the M4 Max model, and that will be even more true for owners of the Mac Studio (M2 Max). Apple hasn’t supplied performance comparisons for that model, but you’d imagine the differences are even smaller. That said, you could argue that this speaks to the longevity of these devices, and the high price tag and lack of upgradability of the new Mac Studio becomes easier to swallow if it’s still going strong in 2028 and you have no need or desire to upgrade it.
As with previous M-class releases, the real leap in performance comes when comparing the Mac Studio with M4 Max to an Intel-based Mac, which Apple stopped producing in 2020 with the launch of the M1 chip.
Again according to Apple, you’re getting around 3x the performance with the Mac Studio M4 Max compared to a 27-inch iMac with an Intel Core i9 CPU, with Topaz Video AI processing seeing up to 5x faster video rendering. These are all vague performance promises by Apple, so take them with a grain of salt and refer instead to our benchmark tests below, where you’ll be able to see just how well the new Mac Studio performs. Still, taking Apple’s claims as hints of the kind of performance the new Mac Studio is capable of suggests that people using Intel-based Macs will see the biggest benefit from upgrading.
Apple also surprised us by announcing an even more powerful Mac Studio, powered by the brand-new M3 Ultra chip. The reason why this is particularly surprising, and potentially confusing, is that the M3 Ultra is, as the name suggests, based on the previous generation M3 chip architecture, rather than the newer M4.
As with previous Ultra chips, the M3 Ultra is made up of two Max chips (in this case, two M3 Max chips), which are connected via an ultra-fast bridge to turn them into a single, extremely powerful, chip.
So, while you’re getting up to a 16-core CPU, 40-core GPU, 128GB unified memory, 546GB/s memory bandwidth, and 16-core Neural Engine with the M4 Max, the M3 Ultra offers up to a 32-core CPU, 80-core GPU, 512GB unified memory, 819GB/s memory bandwidth, and 32-core Neural Engine.
Essentially, even with previous-gen tech (the M3 Max was launched in October 2023), the M3 Ultra blows past the M4 Max. Apple hasn’t explained why it went with M3 rather than M4 as the base, though there have been suggestions that the M4 Max lacks the high-speed bridge (known as UltraFusion) needed to combine two of the chips into an M4 Ultra. However, we also heard similar rumors about the M3 Max, and that has been proven to be incorrect with the announcement of the M3 Ultra.
The M3 architecture has seen a few additions with the M3 Ultra, which makes it able to compete feature-wise with the M4 Max. The M3 Ultra now supports Thunderbolt 5 USB-C ports and speeds of up to 120Gbps, and supports up to 512GB of unified memory, both upgrades over the M3 Max.
So, currently, the most powerful Apple silicon is not an M4 chip, but an M3 chip, and that could be a bit confusing – as such, I’m pleased that Apple is being transparent about the M3 Ultra being based on M3 Max chips, rather than fudging the naming conventions to call it an M4 Ultra.
While the Mac Studio with M4 Max will offer performance that most people might not ever need, the M3 Ultra Mac Studio goes even further, promising to offer the kind of performance that will only be needed by large enterprises – think the likes of Pixar when it comes to 3D animation, rather than smaller businesses and individuals, for whom the M4 Max model will likely be more than enough.
Price will also be a factor here, as unsurprisingly these are expensive machines that are professional investments rather than something you’d buy on a whim. The Mac Studio with M4 Max starts at $1,999 / £2,099 / AU$3,499 while the Mac Studio with M3 Ultra starts at $3,999 / £4,199 / AU$6,999 – and these can all be configured to add more power (and cost).
Apple Mac Studio (M3 Ultra): Price and availability
- How much does it cost? M4 Max model starts at $1,999 / £2,099 / AU$3,499
- What about the M3 Ultra? M3 Ultra model starts at $3,999 / £4,199 / AU$6,999
- When is it available? Available to pre-order now, ships March 12, 2025
Apple announced the new Mac Studio on March 5, 2025, and opened preorders at the same time, with the compact PC going on sale on March 12, 2025 globally.
The base model of the new Mac Studio comes with an M4 Max chip featuring a 14-core CPU, 32-core GPU and 16-core Neural Engine, plus 36GB of unified memory and a 512GB SSD, and costs $1,999 / £2,099 / AU$3,499.
This is essentially the same starting price as the previous Apple Mac Studio (M2 Max, though there’s a slight price increase for Australian buyers (the M2 Max model cost AU$3,299). It’s good to see launch prices remain the same in the US and UK, and the new Mac Studio remains a lot cheaper than the $6,999 / £7,199 / AU$11,999 Mac Pro, while offering a more compact design and similar, if not better, performance.
The more powerful M3 Ultra model of the new Mac Studio, meanwhile, starts at $3,999 / £4,199 / AU$6,999. That’s quite a leap, but the specs go some way to justify the high price (while also hopefully making it clear that this machine will be overkill for most people). You get the new M3 Ultra chip with a 28-core CPU, 60-core GPU, and 32-core Neural Engine, plus 96GB unified memory, and a 1TB SSD for storage.
As usual, you can configure the new Mac Studio before you buy, and considering that it’s basically impossible to upgrade the hardware within the machine, it’s important to make sure you take this opportunity to adjust the configuration to suit both your needs and your budget. Adding more powerful components does increase the price, sometimes considerably. The fully-maxed-out Mac Studio comes with an M3 Ultra chip with a 32-core CPU, 80-core GPU, and 32-core Neural Engine, 512GB unified memory and 16TB SSD – those are stunning specs, and they come with an equally stunning price tag of $14,099 / $14,299 / AU$22,149.
Of course, you don’t have to max out all of the specs, so you do have some flexibility; but make no mistake, any configuration of the Mac Studio is going to be extremely expensive. You need to see it as an investment for a business or creative professional. For individual users who want a great-performing compact PC, but don’t need nearly the power on offer with the Mac Studio, then I highly recommend the latest Mac mini, which comes with an M4 chip starting at $599 / £599 / AU$999, or with an M4 Pro starting at $1,399 / £1,399 / AU$2,199. In my view, the M4 Mac mini remains the best Mac Apple has ever made thanks its combination of price, performance, and an all-new design, but creative professionals looking for more power will likely need to choose between the Mac mini M4 Pro or the Mac Studio M4 Max, and in that case the price difference is smaller, though still substantial.
What about non-Mac alternatives? The fact is that there remains no real rival to the Mac Studio in the world of Windows PCs – no one else is making compact workstation PCs that offer professional-grade performance. However, if the size of the machine doesn’t matter, and you don’t mind doing a bit of tinkering, you could put together a workstation PC (or get someone to build it for you) that offers similar levels of performance for less money, although you’d miss out on the Mac Studio’s compact design and ease of use.

Apple Mac Studio (M3 Ultra): Design
- Looks the same as previous models on the outside
- Now comes with Thunderbolt 5 ports
- M3 Ultra model is slightly heavier
Perhaps the biggest selling point of every generation of Mac Studio has been its design, and while the new Mac Studio doesn’t feature any major changes, that remains true.
It’s a testament to Apple’s designers and engineers – and to the power efficiency of M-class chips like the M4 Max and M3 Ultra, which enables Apple to put powerful hardware into compact designs without them overheating.
The latest Mac Studio is unmistakably an Apple product. Its compact dimensions of 3.7 x 7.7 x 7.7 inches / 9.5 x 19.7 x 19.7cm, with a weight starting at 6.1lbs / 2.74kg means it’s easy to find space for it on a desk, and you can hide it behind a monitor if you want, and it also means it’s easy to pick up and move if needed.
The silver body (you don’t get any fun color choices with the Mac Studio, this is all about professionalism) is sleek and minimalist, with a black Apple logo on the top. On the front of the Mac Studio are two USB-C ports (which if you get the model with the M3 Ultra will be Thunderbolt 5), alongside an SDXC memory card slot (always welcome for professional photographers) and a small white LED power light.
The rear of the Mac Studio features four Thunderbolt 5 USB-C ports, a 10Gb Ethernet port, two USB-A ports for legacy peripherals, a HDMI port and a headphone jack. Much of the rear is a grille-like vent that’s used to expel hot air.
The most recent Mac mini got a major design overhaul to make it look more like the Mac Studio, and for the most part the new look was a triumph. However, Apple’s decision to place the Mac mini’s power button on the underside of the device did frustrate some people, as you have to lift up the Mac mini to turn it on or off.
The good news is that Apple hasn’t seen fit to move the Mac Studio’s power button to the underside of the device to match the new Mac mini – it’s still located on the rear of the Mac Studio on the left.
As someone who likes using big, ugly desktop PCs I’ve never had a problem with having a power button on the front of a device for easy access, and some people might find having the button hidden at the rear makes it a little awkward to reach. It does mean, though, that the Mac Studio’s front looks clean and minimalist, which many Apple fans will appreciate, and at least you don’t have to lift up the Mac Studio to reach the button. If you have other Apple devices, particularly the Studio Display, then the new Mac Studio will fit in brilliantly.
The Mac Studio is made with 30% recycled content, according to Apple, with 100% recycled aluminum used for the case, and doesn’t contain mercury or PVC. The packaging is also entirely fiber-based, and is part of the Apple 2030 project, which aims to make the company’s entire carbon footprint neutral by the end of the decade.
Overall, while some people might be clamoring for a bold redesign, the reason why the latest Mac Studio still looks identical to the first one launched back in 2022 is because, frankly, Apple nailed the design first time. It looks modern, and more stylish than any Windows-based compact PC; and with the Mac mini having recently been redesigned to look more like the Mac Studio, I think this look is going to stick around for a long time.
The one major drawback with the design is that it’s essentially impossible to open up the Mac Studio and upgrade or repair components. This might not come as a surprise to anyone familiar with Apple’s products, but it does impact the flexibility of the Mac Studio when compared to traditional tower desktop PCs, which are usually quite straightforward to upgrade. It also undermines Apple’s environmental credentials a little, though the company does offer an upgrade program whereby you can trade in your older Mac for money off the new model.
Also, despite the new Mac Studio coming with some of the latest and most powerful components on the market, Apple’s designers have for some reason decided to stick with older wireless technology: Wi‑Fi 6E (802.11ax) and Bluetooth 5.3, which means you’re missing out on the performance benefits of Wi-Fi 7 and Bluetooth 5.4.
While the wireless tech in a professional-grade workstation might not be at the top of most people’s list of priorities (you’ll likely be using an Ethernet cable for networking), it’s still a bit of an odd omission considering the no-holds-barred design approach Apple has taken to the rest of the Mac Studio’s design.
Apple Mac Studio (M3 Ultra): Performance
- The M3 Ultra is now the most powerful chip Apple has ever made
- It’s likely to be overkill for most people
- The new Mac Studio remains quiet even when under load
When I learned that Apple was sending me the new Mac Studio with the M3 Ultra chip, I was both excited and apprehensive. Excited because I really wanted to see what such a powerful, even over-the-top, piece of silicon could do.
While the M4 Max chip is certainly no slouch, we’ve had the chance to see how it performs since the launch of last year’s MacBook Pros. However, the M3 Ultra, despite being based on the older M3 Max chip, is entirely uncharted territory, and has the potential to blow Apple’s other chips out of the water when it comes to pure performance. The idea that I could play around with this ridiculously powerful hardware and try to push it as hard as possible got my nerd senses tingling.
So why was I also apprehensive? Mainly because how do you begin reviewing a hardware configuration that will be overkill for the needs of maybe 98% of our readers? No matter how good the M3 Ultra is (and I’ll get to just how good it is in a moment), for the vast majority of people I would still recommend they don’t buy it, and instead get the M4 Max model – and for most, the M4 Mac mini would be a much more sensible buy.
In some ways this is Apple’s problem – and it’s a good problem to have. Because its M-series chips have been so good, generational leaps can be less visible to mainstream customers. If you still use a Mac with an M1 or M2 chip there’s a good chance that it’ll still do almost everything you need it to. If not, then upgrading to an M4 Mac, such as the new MacBook Air or the Mac mini (sorry, I keep mentioning it, but I really love that little PC) is a much more affordable option that will keep you chugging along nicely. A smaller percentage of people who need more power for creative applications will find the M4 Max in the MacBook Pro or new Mac Studio more than enough; and if it isn’t enough power, then the M3 Ultra will be extremely welcome.
To be blunt, the number of people who will need the full power of the Mac Studio with M3 Ultra will be limited. But, if you do need an extremely powerful PC for rendering complex 3D models, animating feature-length films, or even developing and testing games, then the new Mac Studio with M3 Ultra will be a very attractive package indeed.
The Mac Studio Apple sent me to review comes with the highest-end M3 Ultra chip with a 32-core CPU (made up of 24 performance cores and eight efficiency ones), an 80-core GPU and a 32-core Neural Engine. It also has 256GB of unified memory, and a 4TB SSD. While it’s not completely maxed out, this is an incredibly powerful bit of kit. The 256GB unified memory doesn’t just act like standard RAM in a PC, but is shared with the 80-core GPU, which means the Mac Studio I’m reviewing is an incredibly powerful device for graphic-intensive tasks. The fact that all this power is contained in a compact body that remains impressively quiet, even when under stress, is particularly impressive.
So it’ll come as no surprise to learn that for regular day-to-day tasks, the Mac Studio absolutely zips by, with macOS Sequoia and apps such as Photoshop running incredibly smoothly. Web browsing with Safari and Chrome, with multiple tabs open, certainly doesn’t challenge the Mac Studio. Chrome might still be a memory hog, but with 256GB of the stuff you’re not going to miss a beat.
Even if you buy the Mac Studio in a less powerful configuration, the results will very likely be the same. Of course, you’re not buying an uber-powerful computer like the Mac Studio to browse the web and write up documents. The Mac Studio has been built to handle demanding creative tasks, and it’s here that it really excels.
Editing high-quality 4K footage in Adobe Premiere Pro was extremely quick and smooth, and I was able to scrub through the footage quickly to find points in the timeline, while previewing any changes I made instantly. The super-fast SSD meant that video files were loaded and complex projects saved very, very quickly (using the Blackmagic Disk Speed Test app, the SSD hit write speeds of 7,115.6 and read speeds of 5,799MB/s).
Even when working with large 4K video files and multi-scene projects (while browsing the web and writing up this review at the same time), I never felt like I was ever really pushing the Mac Studio (hence the apprehension I mentioned earlier), as I don’t have access to files and projects from professional movie studios, to pick a more demanding and likely use case for the new Mac Studio.
Apple Mac Studio (M3 Ultra) benchmarks
Here’s how the Apple Mac Studio (M3 Ultra) performed in our suite of industry-standard benchmarks and game tests.
Geekbench 6:
Single – 3,240
Multi – 28,485
Blackmagic Disk Speed Test:
Read: 5,799MB/s
Write: 7,115.6MB/s
Cinebench:
Single-core – 150
Multi-core – 3,015
GPU – 19,663
What I could see, however, is that the real value of the new Mac Studio lies in its potential to speed up creative workflows. If you can create, code, compile and more, so much more quickly, it means projects can be completed more quickly. This could in turn reduce costs for large-scale businesses, and it also allows professionals to take on more clients. Even with the lowest memory configuration for the M3 Ultra model, 96GB, there’s plenty of headroom to run multiple tasks simultaneously, which again potentially makes a huge difference to productivity.
Throughout all my testing with the Mac Studio it remained incredibly quiet – a welcome change from the desktop PCs I usually use, which have fans that like to whirr into life at the drop of a hat. During some particularly demanding benchmarks I did notice the top of the Mac Studio got quite hot to touch, but it certainly wasn’t alarming – and the fans still remained all but silent. I also didn’t notice any instances of the M3 Ultra being throttled (a process whereby components are deliberately slowed down to avoid overheating, which impacts performance), though again I wasn’t subjecting the Mac Studio to industry-level workloads – but I really can’t imagine too many scenarios where the Mac Studio’s performance wouldn’t be enough.
This is of course great news for people who need that performance, but it also underscores why the Mac Studio won’t be for everyone, especially considering the price.
