Apple now charges about $44 a gigabyte for the Mac Studio's local model memory
A maxed 256GB Mac Studio has gone from $7,499 to $11,299 in 18 months, and the reported rise in LPDDR5X prices explains under a third of that. Anyone refreshing a local-inference box needs both numbers.

What happened
- In the 18 months since the previous model, the Mac Studio's M5 Max base price rose $500 to $2,500, and the M5 Ultra now starts at $5,500, up $1,500 from the M3 Ultra's starting price.
- Apple's top Mac Studio configuration, with a 36-core CPU, 80-core GPU, 256GB of unified memory and 2TB of storage, costs $11,299.
- Engadget notes the M3 Ultra with the same 256GB of RAM and 2TB SSD retailed for $7,499 at launch, making the current flagship $3,800 more expensive.
- Engadget reports Apple was paying around $6 per gigabyte for LPDDR5X memory earlier this year, and that the figure may now be closer to $10 or $11.
- The cheaper Mac Mini tops out at an M5 Pro processor, 64GB of RAM and 307 GB/s of memory bandwidth.

Why it matters
- cost The memory capacity line now sets whether a local-inference build clears its budget, and the cost lands on whoever signed the spec.
- decision Anyone who budgeted a 256GB Studio refresh at last year's price is choosing between buying less memory than the workload needs and going back to finance for more money.
- constraint The four-machine Thunderbolt cluster Apple holds up as the high end costs $45,196 for 1TB of unified memory. A purchase that size sits outside most teams' discretionary spend and goes through the capital process.
- precedent Apple has now passed component inflation into list prices twice in a year and said so in writing, so a quote on a memory-heavy configuration should be treated as good only for the day it was issued.
A 256GB Ultra with 2TB of storage divides out to about $44 per gigabyte of unified memory [1]. The M3 Ultra version of that same 256GB, 2TB machine divided out to about $29 [2]. Capacity did not change and the price went up 51% [10].
The component story covers part of that. At the earlier rate Engadget reports, 256GB of LPDDR5X cost Apple roughly $1,536; at the midpoint of the current range, roughly $2,688 [4]. The $1,152 difference accounts for under a third of the increase on that configuration [5].
Engadget puts the total memory bill for the 256GB machine at around $2,500 to $2,800 and says it retails for far more than that [8]. The publication attributes the rest to storage prices, hedging and Apple's margins [5]. Apple said in June, when it raised MacBook prices, "We've never seen component prices increase this much, this quickly. We've worked hard to absorb these costs and delay price increases for as long as possible, but the current environment has made that unsustainable." [6]
The Ultra gets the headlines, and the $500 on the M5 Max base is the number that lands in ordinary refresh budgets, a 25% rise on what was a $2,000 machine [2][8]. Stepping down is not much of an option. The Mac Mini stops at 64GB, so a workload that needs 128GB or 256GB resident has nowhere cheaper to sit in the Apple desktop line [9][1].
Engadget's account covers Apple's price list and Apple's explanation of it. Other workstation vendors and GPU builders are not in it, so it cannot tell you how a non-Apple refresh prices out.
The purchase turns on whether the model has to stay on your premises and whether the load is continuous or bursty. If it is continuous and local, $44 a gigabyte is the right price, because the memory is occupied every working day and there is nothing to rent instead. Bursty and portable work puts $11,299 spread over 36 months, about $314 a month before power, against a rented endpoint [6]. Mixed cases come down to how many hours a week the box sits idle. Apple describes the Ultra's job as being to "store huge datasets entirely in local memory, increase the tokens-per-second speed and run huge LLMs with hundreds of billions of parameters entirely on device" [12].
What to watch
- The 512GB M5 Ultra option Engadget says arrives next month, and what it prices per gigabyte of memory.
- Whether the reported $6-to-$11 move in LPDDR5X per-gigabyte cost is confirmed by supplier or Apple disclosure.
- Whether non-Apple workstation vendors publish comparable increases on memory-heavy configurations.
