When will the M5 Ultra Mac Studio be released?

Bloomberg reported in April 2026 that the Mac Studio refresh would launch around October 2026, delayed from early 2026 by memory chip supply issues and price increases. As of August 2026 an October launch is not confirmed, and reporting notes it could slip further.

How much RAM will the M5 Ultra Mac Studio have?

Per MacRumors (June 2026), Apple has tested M5 Ultra support for up to 768GB of unified memory, but supply constraints may prevent that config from shipping. The M5 Ultra is expected to start at 96GB, with roughly 36 CPU cores and 80 GPU cores. Treat everything beyond the 96GB base as unconfirmed.

Should I buy a Mac Studio now or wait for the M5 Ultra?

Wait only if you specifically need more than 128GB of unified memory and can work another quarter or more without it. Buy now if 96-128GB covers your models: the current M3 Ultra tops out at 96GB from $5,299, a MacBook Pro M5 Max offers 128GB at 614 GB/s for $6,899-6,999, and Apple's 2026 pattern — pulling the 512GB config in March and the 256GB in May, then raising prices in June — argues against betting on a bigger, cheaper machine appearing on schedule.

Is a used M3 Ultra Mac Studio 256GB a good buy in 2026?

It is the contrarian play with real logic behind it. Apple no longer sells any Mac with more than 128GB of unified memory (the Studio caps at 96GB), so used 256GB and 512GB M3 Ultra machines are the only Apple hardware at that tier — and if the M5 Ultra ships memory-constrained, they stay that way. The risks are price (they trade at a scarcity premium), no warranty runway, and an October event that could reset the market overnight.

Should You Wait for the M5 Ultra Mac Studio? (August 2026)

The M5 Ultra Mac Studio is expected around October 2026, delayed from early 2026 by the memory shortage. Whether to wait depends on one uncomfortable fact: Apple has spent 2026 removing big-memory configs, not adding them.

Bottom Line (August 2026)

Expected timing: ~October 2026 (Bloomberg, April 2026), already slipped once from early 2026. Not confirmed.
Expected memory: starts at 96GB; Apple has tested up to 768GB, but supply constraints may keep big configs off the order sheet. ~36 CPU / ~80 GPU cores rumored.
Wait if you need >128GB unified and can hold out a quarter (or more).
Don’t wait if 96-128GB covers you — the machines that do that exist today, and 2026’s pattern is configs disappearing and prices rising, not the reverse.
The contrarian buy: a used M3 Ultra 256GB, the only >128GB Apple hardware that exists at any price.

What’s Actually Coming

Per MacRumors (June 25, 2026) and subsequent reporting: the M5 Ultra is expected to fuse two M5 Max dies, landing around 36 CPU cores and 80 GPU cores, with unified memory from 96GB. Apple has tested support up to 768GB — a number that would make the Mac Studio the largest-memory local-AI machine a consumer can buy by a wide margin. The launch was pushed from early 2026 to ~October by the DRAM shortage.

Two M5 Max dies also implies roughly double the M5 Max’s 614 GB/s bandwidth — the M3 Ultra manages ~800 GB/s on the older design. We won’t quote a figure Apple hasn’t shipped; the point is that an Ultra at 96GB would be a faster machine but not a bigger one than a $6,899 M5 Max MacBook Pro at 128GB. If the big configs don’t ship, the launch machine may hold less memory than the laptop.

The Fact the Wait-For-It Crowd Skips

Apple’s 2026 track record on big-memory Macs runs one direction. March: the 512GB M3 Ultra config is removed. May: the 256GB config follows, leaving 96GB as the ceiling. June: prices rise — the M3 Ultra Studio now starts at $5,299, up $1,300. Our biggest Mac Studio guide documents the whole retreat.

So the wait is not “current lineup vs current lineup plus a 768GB monster in October.” It is a bet that the same company that spent 2026 deleting big-memory SKUs will, in a worsening memory market, ship its biggest one ever, on time, at a price you’d pay. Possible. Not the way to plan a purchase you need this quarter.

The Cost of Waiting, Priced

Waiting is not free. If the machine you’re deferring would replace API spend, a quarter of waiting has a dollar figure — for a heavy agentic workload that’s routinely hundreds of dollars a month (our electricity break-even page has the local-side math). And if the M5 Ultra launches into the same shortage, launch pricing will reflect it: the DGX Spark took a +$700 official MSRP hike to $4,699 for exactly this reason.

What to Do, By Situation

Your models fit in 96-128GB (gpt-oss 120B Q6/Q8, Qwen3.5-122B, 70B dense at Q8 — most people): buy now. The MacBook Pro M5 Max 128GB at $6,899-6,999 is the current best Apple machine for local AI; the Mac Studio M4 Max (from $2,499, configurable to 64GB) covers the tier below it for far less.

You genuinely need more than 128GB (400B-class MoE at real quants, DeepSeek-class experiments): you have three options. Wait for October and accept the schedule risk. Hunt a used M3 Ultra 256GB — the only Apple hardware ever sold at that tier, trading at a scarcity premium precisely because Apple stopped making it. Or leave Apple: the DGX Spark gives 128GB of CUDA-side unified memory at $4,699, and clustering two is NVIDIA’s own answer to the 1M-context problem.

You’d wait just to see: set the trigger conditions now. Wait becomes buy the day Apple either (a) opens orders with ≥256GB configs, or (b) announces without them — because (b) tells you the used M3 Ultra 256GB market is the ceiling for another cycle, and those machines will not get cheaper on that news.
