NVIDIA GH200 (144GB HBM configuration) vs NVIDIA DGX Spark (Project DIGITS, 128GB)
Hardware specifications
Compare memory capacity and reported specifications for NVIDIA GH200 (144GB HBM configuration) and NVIDIA DGX Spark (Project DIGITS, 128GB). Comparable speed evidence depends on matching model, runtime, quantization, context and batch; a specification comparison does not establish a speed winner.
| Device | GPU or unified memory | GPU power rating |
|---|---|---|
| NVIDIA GH200 (144GB HBM configuration) | 144GB | 1000W |
| NVIDIA DGX Spark (Project DIGITS, 128GB) | 128GB | 240W |
Power ratings are not measured whole-system draw. Unified memory is shared with the operating system. Check the exact hardware configuration, artifact size, runtime buffers and KV cache before choosing a device.
