On October 28, 2026, Apple opened up the 512GB memory option for the Mac Studio M5 Ultra on its online store. The company had promised it for late October and it delivered on time. The price of entry is steep, though: at least $22,299 in the US, according to MacRumors.
Mac Studio M5 Ultra: what the memory really costs
Not every version of the machine can take the full 512GB. The option requires the M5 Ultra model with a 36-core CPU and an 80-core GPU, which starts at $6,799. On top of that base, 512GB of RAM adds $15,500, bringing the minimum bill to $22,299.
It can climb further. Pair that memory with 16TB of storage and the configuration reaches $29,799. These are US Apple Store prices; the source we consulted did not give European pricing.
- M5 Ultra base (36-core CPU, 80-core GPU): from $6,799
- 512GB RAM option: +$15,500
- Minimum total with 512GB: $22,299
- 512GB RAM and 16TB storage: $29,799
What about the Mac Studio M5 Max?
It stays capped at 128GB of memory. If your workload needs more than that, the Ultra is the only way into the Mac Studio range.
Who is a setup like this for?
Let’s be honest: most buyers will never need it. That much unified memory, shared between the processor and the GPU, targets very specific profiles, such as people handling huge datasets or very heavy compute projects. Apple did not spell out a target use in the announcement relayed by MacRumors, so we won’t speak for the company.
What is clear is the message: the Mac Studio range is pushing memory higher, at a price now counted in tens of thousands of dollars.
The bottom line
The 512GB Mac Studio M5 Ultra can be ordered today, but it is a professional purchase starting at $22,299. Would a machine like this earn a place on your desk? Tell us in the comments, and keep reading our Apple coverage on Wanda-techs.com.
