The Mac Studio M5 Ultra is Apple’s most powerful Mac yet, and it starts at $5,499. It went on sale on September 22, 2026, but the headline 512GB memory option doesn’t ship until late October.
So if you’re eyeing this machine for big AI models or heavy video work, the order you place today may not be the one you actually want.
- Price: M5 Ultra starts at $5,499; M5 Max starts at $2,499
- On sale: September 22, 2026
- Memory: up to 128GB on M5 Max, up to 512GB on M5 Ultra
- Delay: the 512GB configuration arrives in late October
- Ports: Thunderbolt 5, up to 120Gb/s
Those are the numbers from Apple’s own launch announcement. The rest of this guide shows what they mean in practice.
Mac Studio M5 Ultra vs M5 Max: what the extra money buys
Apple sells two chip tiers. The gap between them is large, and so is the price difference.
| M5 Max | M5 Ultra | |
|---|---|---|
| Starting price | $2,499 | $5,499 |
| CPU | 18-core | Up to 36-core |
| GPU | Up to 40-core | Up to 80-core |
| Max memory | 128GB | 512GB (late October) |
| Education price | $2,299 | $5,099 |
The M5 Ultra also has 1.2TB/s of memory bandwidth, which is how fast the chip can move data in and out of that memory. That matters most for AI work, where models are constantly read from memory.
Apple says the M5 Ultra is up to 1.8x faster at graphics than the M3 Ultra, and up to 4.3x faster for AI work. These are Apple’s own claims, so wait for independent tests before you treat them as fact.
Why 512GB of memory is the real story
Most people won’t need half a terabyte of memory. A few will, and they’re the ones this Mac was built for.
Large language models are the main reason. A model has to fit in memory to run well, and bigger models need more of it. With 512GB of unified memory, the CPU and GPU share one big pool instead of splitting it.
That’s why this machine is getting attention from people who run local AI models at home or in a small studio. If that’s you, our look at the M6 Mac mini shows the cheaper end of Apple’s lineup.
For everyday work, the picture is different. Photo editing, coding and most video projects run comfortably in far less memory, so paying for 512GB would be money spent on headroom you never touch.
The catch is timing. Apple lists the 512GB option for late October, with no exact date. If you need it, plan around that window.
Clustering, ports and displays
Apple also built this Mac Studio to work as part of a group. Here’s what it supports.
- Thunderbolt 5 with transfer speeds up to 120Gb/s.
- RDMA clustering, which lets several Mac Studios share work. Apple claims up to 3x faster distributed AI inference than a single machine.
- Up to eight displays, or up to four Studio Display XDR panels at 5K and 120Hz.
Clustering is the interesting part. Instead of buying one giant machine, you could link a few and pool their power. Whether that works as smoothly as Apple says is something we’ll know once reviewers try it.
Which Mac Studio should you buy?
Start with the M5 Max if you edit video, produce music or work in 3D but don’t run huge AI models. At $2,499 it’s already a very fast desktop, and 128GB of memory covers most creative projects.
Step up to the M5 Ultra if memory is your bottleneck. That means large local models, huge scenes or datasets that your current Mac can’t hold. For these jobs, the extra $3,000 buys time you’d otherwise lose to slow swapping.

How much does it cost to finance or lease?
Apple Upgrade leasing starts at $48.99 a month for the M5 Max and $110.10 a month for the M5 Ultra. Both run for 36 months, before taxes and trade-in credit.
Education pricing takes $200 off the M5 Max and $400 off the M5 Ultra, so students and teachers should check that option first.
Frequently Asked Questions
How much does the Mac Studio M5 Ultra cost?
It starts at $5,499, or $5,099 with education pricing. The M5 Max version is cheaper at $2,499.
When can I buy the Mac Studio M5 Ultra?
It’s on sale now, since September 22, 2026. Only the 512GB memory option is delayed until late October.
How much memory does the M5 Ultra support?
Up to 512GB of unified memory. The M5 Max tops out at 128GB.
Is the Mac Studio good for running local AI?
On paper, yes. Its large shared memory and 1.2TB/s of bandwidth are what local AI models need, though independent benchmarks are still limited.
Is the M5 Ultra worth it over the M5 Max?
Only if you need more than 128GB of memory or the extra GPU power. Most editors and designers will be happy with the M5 Max.
Our take
Buy the M5 Max unless you can name the exact job that needs more. The M5 Ultra is a specialist tool, and the 512GB version isn’t even shipping yet. If you truly need that memory, wait for late October and look for real-world test results before you spend $5,499 or more.
