Apple Drops 512GB RAM Option for Mac Studio
Apple has quietly removed the 512GB RAM configuration for the Mac Studio, which now maxes out at 256GB. The change is attributed to a global DRAM shortage, potentially impacting developers and ML teams who rely on high-memory local machines for demanding workloads.
The shift in the memory market is structural, not cyclical. Major manufacturers like Samsung, SK Hynix, and Micron are reallocating wafer fabrication capacity away from standard DRAM towards more profitable High-Bandwidth Memory (HBM) to supply the AI data center boom. This reallocation is significant, as each gigabyte of HBM can consume up to three times the wafer capacity of the DDR5 memory used in consumer devices. This supply shift has triggered a massive price surge across the industry. DRAM prices have increased 171% year-over-year, with spot prices for DDR5 quadrupling since September 2025. The shortage and its associated costs are expected to persist through 2026, with analysts predicting relief only when new fabrication plants become operational in 2027. The impact is already visible in Apple's product line beyond just the removal of the 512GB option. The upgrade price from 96GB to the new maximum of 256GB on the M3 Ultra Mac Studio has increased from $1,600 to $2,000. Furthermore, shipping estimates for this top-tier 256GB configuration have now been delayed until May, indicating a tightening supply. For local development, the 512GB unified memory configuration was a key enabler for running large language models with over 120 billion parameters without resorting to power-hungry multi-GPU server rigs. Its removal eliminates a unique hardware option for developers and researchers working on large-scale AI models directly within the Apple ecosystem.
