Mac Studio M3 Ultra
Apple · Enthusiast
Apple's top desktop chip in the Mac Studio, with high-bandwidth unified memory shared between CPU and GPU. Its memory bandwidth is the highest of any Apple Silicon, which makes it one of the better Apple options for running larger models.
Specifications
| Unified memory | 96GB |
|---|---|
| Memory bandwidth | 819 GB/s |
| Power draw | 180W |
| Type | complete machine |
A complete machine, so compare it against a full build rather than a card. Note that Apple cut the higher-memory M3 Ultra options during 2026 amid a DRAM shortage, so the larger configurations that were available at launch may no longer be. Check the current line-up before buying.
Strengths
- The highest memory bandwidth of any Apple Silicon, so faster generation
- Large unified memory runs models that need far more than a 24GB card
- Very low power and near-silent for the capability
Weaknesses
- Memory bandwidth still trails high-end discrete GPUs, so slower than they are
- Memory is fixed at purchase and cannot be upgraded
- Available memory configurations narrowed during 2026, reducing the ceiling
