Apple Removes 512GB Memory Option From Mac Studio
6.1
Apple on March 6, 2026 removed the 512 GB unified memory option for the Mac Studio, capping maximum RAM at 256 GB and raising the 256 GB upgrade price from $1,600 to $2,000 (a $400 increase). Apple discontinued the 512 GB M3 Ultra configuration amid ongoing DRAM supply constraints; the 256 GB option still supports large local LLM workloads but reduces headroom for the largest models.
Key Points
- 1Discontinues 512 GB unified memory option on Mac Studio, now capped at 256 GB.
- 2Cites DRAM supply constraints and rising component costs prompting SKU reductions.
- 3Reduces headroom for running largest local LLMs; practitioners may need external GPUs or compression.
Scoring Rationale
Notable product configuration change affecting Mac Studio users; moderate industry relevance but limited novelty and single-source reporting.
