What AI models can the NVIDIA RTX Spark N1X (6144-core GPU) (64 GB) run?
- Unified memory
- 64.0 GB
- Usable for models
- 48.0 GB
- Memory bandwidth
- 300 GB/s
- FP16 compute
- 28.8 TFLOPS
- Released
- 2026
macOS lets the GPU use roughly two-thirds to three-quarters of unified memory by default, so we plan around that figure rather than the full 64.0 GB.

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
