Mac Studio M5 Max vs. M5 Ultra vs. M3 Ultra: Specs and Price

The Mac Studio with M5 Max starts at $2,499 and the Mac Studio with M5 Ultra starts at $5,499, and both are shipping now. The headline news for anyone who has been waiting, though, is the configuration Apple hasn't shipped yet: a Mac Studio with M5 Ultra and 512GB of unified memory, which Apple says is "coming in late October" 2026 — which, as of this writing, is any day now. Here's exactly how the new M5 Max and M5 Ultra compare to each other and to the M3 Ultra chip most high-memory buyers are upgrading from, on cores, memory, bandwidth and price.

Mac Studio M5 Max and M5 Ultra: pricing and availability

Apple announced the new Mac Studio lineup on August 25, 2026. Pre-orders opened the same day, and units began arriving to customers, Apple Store locations and Apple Authorized Resellers on September 22, 2026. U.S. starting prices are:

• Mac Studio with M5 Max: $2,499 ($2,299 for education)
• Mac Studio with M5 Ultra: $5,499 ($5,099 for education)

Those are starting prices for the base configuration of each chip — 36GB of memory and a 512GB SSD for the M5 Max, 96GB of memory and a 1TB SSD for the M5 Ultra. Every spec bump, from additional CPU and GPU cores to more memory and storage, costs extra when you configure a Mac Studio on Apple's site. Apple hasn't published a price for the one configuration everyone is waiting on: Mac Studio with M5 Ultra and 512GB of unified memory, which the company says is coming in late October 2026 but hasn't yet priced or dated more precisely than that.

What's actually new in the M5 generation

The M5 Max and M5 Ultra aren't just a clock-speed bump. Two changes matter most for buyers:

• Neural Accelerators built into the GPU. For the first time, every GPU core in the M5 Max and M5 Ultra includes a dedicated Neural Accelerator, which Apple says dramatically speeds up on-device AI and machine-learning workloads — the kind of local large-language-model inference that's become the main reason people buy a maxed-out Mac Studio in the first place.
• A new Apple-designed N1 networking chip handling Wi-Fi 7 and Bluetooth 6, arriving on Mac Studio for the first time.

Apple also widened the I/O: the new Mac Studio offers up to six Thunderbolt 5 ports (up to 120Gb/s each) across front and rear, support for Thunderbolt 5 clustering with RDMA — Apple says four linked systems deliver up to 3x faster AI inference than one machine — and what Apple calls a next-generation SSD architecture that's up to twice as fast as before. (Apple's initial release referenced a specific PCIe generation for that SSD architecture in some regional versions before quietly dropping the mention from its English-language materials, so treat the exact interface generation as unconfirmed rather than official.) The full breakdown of every spec lives on Apple's own Mac Studio technical specifications page.

CPU and GPU cores, explained

Apple's naming inside the M5 generation's CPU is new: instead of the "performance and efficiency" core split Apple has used since the first M1, the M5 Max and M5 Ultra are built from "super cores" and "performance cores." The M5 Max ships in a single configuration — an 18-core CPU with 6 super cores and 12 performance cores — paired with a 32-core GPU that can be configured up to 40 cores. The M5 Ultra, which is effectively two M5 Max dies fused together over Apple's UltraFusion interconnect, starts at a 30-core CPU (10 super + 20 performance) and 64-core GPU, and can be configured up to a 36-core CPU (12 super + 24 performance) and 80-core GPU.

The M3 Ultra it replaces used Apple's older core design: a 28-core CPU (20 performance + 8 efficiency cores) and 60-core GPU at the entry configuration, stepping up to 32 CPU cores and 80 GPU cores at the top. So on raw core counts, the jump from M3 Ultra to M5 Ultra is modest at the high end (80 GPU cores either way) but the base configuration actually gains CPU cores (28 to 30) along with two full chip generations of per-core performance and efficiency gains, plus the new Neural Accelerators Apple has added to every GPU core.

Unified memory and bandwidth

Memory capacity is where the Mac Studio earns its reputation as a workstation for local AI work, not just video and 3D. The M5 Max tops out at 128GB of unified memory with 614GB/s of bandwidth in its 40-core GPU configuration (460GB/s at the base 32-core GPU configuration). The M5 Ultra goes much further: 96GB standard, configurable to 256GB or 512GB, with 1.2TB/s of memory bandwidth — roughly half again as much bandwidth as the M3 Ultra's "over 800GB/s," which independent testing has put close to 819GB/s.

That bandwidth number matters as much as capacity for anyone running large language models locally: a bigger memory pool lets you load a bigger model, but bandwidth determines how fast tokens actually get generated once it's loaded. The M5 Ultra's 1.2TB/s is the single biggest practical reason to consider it over an M5 Max, independent of how much memory you actually buy.

The 512GB configuration: what we know, and don't

Apple confirmed in its August 25 announcement that a Mac Studio with M5 Ultra and 512GB of unified memory is coming, but didn't ship it alongside the rest of the lineup. The company's language is simply that it's "coming in late October" 2026 — no specific date, and critically, no price. Given that the jump from the 256GB to 512GB memory configuration has historically been one of Apple's most expensive single upgrades (on the M3 Ultra generation, a fully maxed-out 512GB/16TB configuration ran well into five figures), expect the 512GB M5 Ultra to land several thousand dollars above the $5,499 starting price once storage and memory are configured up.

If your workload genuinely needs 512GB of unified memory — running the very largest local language models without quantization, for instance — that late-October availability is the one date on this page actually worth waiting for. Everything else in the M5 Max and M5 Ultra lineup, including 256GB M5 Ultra configurations, is already shipping.

Storage, ports and expansion

Both new chips share the same port layout: up to six Thunderbolt 5 ports (four rear, two front or two USB-C depending on configuration), two USB-A ports, HDMI 2.1, 10Gb Ethernet, a 3.5mm headphone jack and an SDXC card slot. Thunderbolt 5's 120Gb/s per-port bandwidth is what makes Apple's new clustering feature possible — linking up to four Mac Studios over Thunderbolt 5 with RDMA for distributed AI inference — and it's also what feeds external PCIe expansion chassis for additional storage or capture cards, the same category of hardware we cover in our look at PCIe 6.0 and PAM4 signaling.

Internally, storage starts at 512GB on the M5 Max and 1TB on the M5 Ultra, both configurable up to 8TB and 16TB respectively. Apple says the new SSD architecture is up to twice as fast as the previous generation's, though the company hasn't published a specific throughput number in its U.S. materials.

M5 Max vs. M5 Ultra: who should buy which

The gap between these two chips is bigger than a simple spec bump — it's really two different buyers. The M5 Max, at $2,499, is the Mac Studio for people who want desktop-class performance in the compact Mac Studio enclosure but don't need Apple's most extreme memory ceiling: video editors cutting 4K and 8K timelines, developers compiling large codebases, 3D artists working in moderate scene complexity, and anyone running smaller local AI models that fit comfortably inside a 128GB memory ceiling.

The M5 Ultra, starting at $5,499, exists for workloads that are memory- and bandwidth-bound rather than purely compute-bound: training or fine-tuning on-device, running the largest open-weight language models locally without offloading to disk, real-time 8K color grading with heavy node graphs, and scientific or engineering simulation work that benefits from both the extra CPU cores and the doubled memory bandwidth. If your work genuinely saturates an M5 Max's 128GB ceiling, the M5 Ultra isn't a luxury upgrade — it's the only Apple silicon option that fits.

Is it worth upgrading from the M3 Ultra?

If you bought a Mac Studio with M3 Ultra near its March 2025 launch, the case for upgrading now is more about bandwidth and AI-specific hardware than raw core counts — at the top end, both chips can be configured to an 80-core GPU. What's changed is the 1.2TB/s of memory bandwidth (versus the M3 Ultra's over 800GB/s), Neural Accelerators built into every GPU core, the new N1 wireless chip, and a faster SSD architecture. For anyone doing heavy local-LLM inference, that bandwidth increase alone can translate directly into faster token generation at the same memory size.

Price is a more complicated story than it first looks. The M3 Ultra launched at $3,999, but Apple quietly raised Mac Studio pricing in mid-2026, pushing the base M3 Ultra configuration to $5,299 before it was replaced — just $200 under the new M5 Ultra's $5,499 starting price. In other words, anyone shopping new right now isn't choosing between a cheap outgoing chip and an expensive new one; they're choosing between two very similarly priced machines, and the M5 Ultra wins that comparison on every spec that matters. The calculus is different if you already own an M3 Ultra Mac Studio: unless you're bandwidth-starved or need the new Neural Accelerators for local AI work, two generations of architectural refinement without a core-count leap at the top end is a reasonable upgrade to skip.

Buyers who instead prioritize portability over raw workstation power should also weigh Apple's laptop lineup — our comparison of Apple's MacBook Air against a competing laptop covers that side of the Mac lineup in more detail. And for anyone comparing the Mac Studio against non-Apple desktop AI workstations, our breakdown of Nvidia's DGX Spark is a useful contrast point on memory, price and what each platform is actually built for.

Frequently asked questions

When did the Mac Studio with M5 Max and M5 Ultra release? Apple announced both on August 25, 2026, with pre-orders starting the same day. Deliveries and in-store availability began September 22, 2026.

How much does the Mac Studio M5 Max cost? It starts at $2,499 in the U.S. ($2,299 for education), for 36GB of unified memory and 512GB of storage.

How much does the Mac Studio M5 Ultra cost? It starts at $5,499 in the U.S. ($5,099 for education), for 96GB of unified memory and 1TB of storage.

When does the 512GB Mac Studio ship, and how much will it cost? Apple says a Mac Studio with M5 Ultra and 512GB of unified memory is "coming in late October" 2026. Apple has not announced an exact date or price for that configuration.

What's the real difference between the M5 Max and M5 Ultra? The M5 Ultra roughly doubles the M5 Max's CPU and GPU core counts, quadruples its maximum unified memory ceiling (128GB vs. 512GB), and nearly doubles its memory bandwidth (1.2TB/s vs. up to 614GB/s).

Is the Mac Studio M5 Ultra worth buying over the M3 Ultra? For new buyers, yes — the two chips are now priced close together after Apple's 2026 price increases on the M3 Ultra, and the M5 Ultra adds meaningfully more memory bandwidth and on-chip AI acceleration for a similar price. Existing M3 Ultra owners without a bandwidth- or memory-bound workload have less reason to upgrade.

Which Mac Studio should you buy?

Buy the M5 Max ($2,499) if you want a meaningful performance upgrade over the previous-generation Mac Studio without stepping into Ultra-chip pricing, and your memory needs top out around 128GB. Buy the M5 Ultra ($5,499) if your work is bandwidth- or memory-bound — large local AI models, heavy multi-app creative pipelines, or compute clusters — and you don't need more than 256GB of unified memory today. Wait for the 512GB M5 Ultra configuration, arriving in late October 2026, only if your workload specifically requires that much unified memory; Apple hasn't priced it yet, and history suggests it will carry a substantial premium over the $5,499 starting price. And if you already own an M3 Ultra Mac Studio, the upgrade is worth it mainly for the memory-bandwidth jump and the new Neural Accelerators — not for core counts, which barely moved at the top end.
