Mac Studio 2025

The highest configuration Apple ever shipped, and no longer orderable. Apple discontinued the 512GB tier, you can't build this at the store anymore.

Specs

M3 Ultra — 32-core CPU / 80-core GPU / 32-core Neural Engine
512GB unified memory (max; typical Mac Studios ship 36–96GB)
8TB SSD
Thunderbolt 5, 10Gb Ethernet, Wi-Fi 6E, HDMI, SDXC

Why 512GB matters
This is the local-AI machine. 512GB of unified memory runs 400B+ parameter models at Q4 entirely in VRAM DeepSeek R1, Llama 405B, Qwen 235B with ~800GB/s bandwidth. Building equivalent VRAM out of NVIDIA cards costs several times this, pulls 10x the wattage, and won't fit under a desk. Also handles 8K timelines, heavy 3D, and large Logic sessions without flinching. Near-silent under sustained load, ~200W at full tilt.

Condition
Excellent. Purchased new in April, light use. Wiped, Activation Lock removed, fresh macOS install. Ships in original packaging.
