Apple's 512GB Mac Studio vanishes, a quiet acknowledgment of the RAM shortage

Original Article ↗ Hacker News Discussion ↗

Apple has quietly removed the 512GB RAM configuration of its $9,500 Mac Studio, prompting speculation that soaring DRAM prices and constrained supply—driven largely by AI data center demand—have made the top-tier model uneconomical to produce. Commenters debate whether this reflects a genuine shortage or cartel-like behavior by the handful of big memory vendors, and note knock‑on effects such as sharply higher prices for devices like Raspberry Pi boards and high‑capacity DDR5 kits. Many expect Apple to redirect limited memory supply to upcoming M5‑based Macs, possibly with even larger unified memory configurations aimed at local LLM workloads, while warning that soldered RAM and fixed tiers leave buyers exposed to current price spikes.

Mac Studio 512GB Removal & Apple’s Strategy

  • 512GB RAM Mac Studio was niche and very expensive (~$10K), but some report strong demand in certain channels, especially for AI workloads.
  • Main theories for its removal:
    • DRAM price spike makes the config unprofitable or hard to price without PR fallout.
    • Apple sold through its planned production run and doesn’t want to reorder before next-gen chips.
    • Apple may make more money selling multiple 256GB machines instead of one 512GB.
  • Some think it’s tied to an impending M5 Ultra Mac Studio (possibly with 512–768GB RAM) and that Apple wants to avoid buyer regret on a soon-to-be-obsolete $10K machine. Exact roadmap is unclear and based on rumors.

Apple Silicon, AI, and Local Models

  • High‑RAM Mac Studios are seen as compelling for local LLM inference: unified memory is shared CPU/GPU RAM and cheaper per GB than equivalent GPU VRAM rentals.
  • Others argue that for many, slotted RAM PCs with upgradeability or GPU VRAM still make more sense for ML.
  • Concern that soldered, non-upgradable RAM forces overbuying “for future‑proofing,” especially painful during a RAM price spike.

RAM Shortage vs. Cartel Debate

  • Many attribute rising prices and product changes to AI data center demand for DRAM.
  • Others argue the big DRAM vendors act as a de facto cartel via public, coordinated supply cuts, pointing to past price‑fixing cases and long‑term flat real prices.
  • A detailed comment claims large AI players pre‑committed a huge share of global RAM supply, pushing up prices and squeezing consumers, open‑source, and small providers.
  • There is disagreement whether this is primarily genuine scarcity, coordinated supply management, or both.

Broader Hardware Market Effects

  • Raspberry Pi 5 and other SBCs have become much more expensive; several posters now see used x86 mini PCs as better value, with Pis retained mainly for low power, PoE, and ecosystem.
  • Some expect RAM shortages to normalize in 1–3 years, as in past cycles; others say this spike is unprecedented and could be “extinction-level” for low-cost electronics makers.

Future Macs & Positioning

  • Speculation that Apple will:
    • Release an M5 Ultra Studio (possibly 768GB), and maybe a rethought Mac Pro focused on AI.
    • Continue using high RAM tiers in marketing around local model capability.
  • Product naming (Max vs Ultra) and fragmented line (Air/Pro/Mini/Studio/Pro) are seen as confusing.
