NVDGXSPARK-PB, NVIDIA DGX Spark 128GB
Warranty: Lifetime
Condition: New
→ DGX Spark interconnect reference — approved stacking-cable part numbers, real-world throughput, and what to buy at two, three and four or more nodes.
The DGX Spark is built around a single GB10 Grace Blackwell Superchip that tightly integrates the CPU and GPU on one package. Most components (CPU, GPU, and unified memory) are not user-replaceable or field-replaceable units (FRUs) due to the SoC design.
Here is the standard parts/component listing based on NVIDIA's hardware overview and the PNY NVDGXSPARK-PB specifications:
| Component | Specification/Details |
|---|---|
| Superchip | NVIDIA GB10 Grace Blackwell Superchip |
| CPU | 20-core Arm (10x Cortex-X925 performance cores + 10x Cortex-A725 efficiency cores) |
| GPU | NVIDIA Blackwell architecture (6,144 CUDA cores, 5th-gen Tensor Cores, 4th-gen RT Cores) |
| Unified System Memory | 128 GB LPDDR5x (coherent/shared between CPU/GPU; 256-bit interface, ~273 GB/s bandwidth, 4266 MHz) |
| Storage | 4 TB NVMe M.2 SSD (self-encrypting drive / SED; some configs may ship with 1 TB) |
| Networking | - 1x RJ-45 10 GbE - NVIDIA ConnectX-7 SmartNIC with 2x QSFP ports (up to 200 Gbps for stacking two DGX Spark units) |
| Wireless | Wi-Fi 7 + Bluetooth 5.4 (or 5.3 with LE in some refs) |
| Connectivity / I/O | - 4x USB Type-C (one supports power delivery) - 1x HDMI 2.1a (with multichannel audio support) |
| Video Encode/Decode | 1x NVENC + 1x NVDEC |
| Power Supply | External 240W adapter (included; required for full performance — GB10 SoC TDP ~140W) |
| Form Factor | Compact SFF desktop: 150 mm (L) × 150 mm (W) × 50.5 mm (H), ~1.2 kg (2.6 lbs) |
| OS | NVIDIA DGX OS (based on Ubuntu) with full NVIDIA AI software stack preloaded |
| Performance | Up to ~1 PFLOP AI (FP4 with sparsity); supports models up to ~200B parameters (or 405B when stacking two units) |
Included in the box (typical for this model):
- DGX Spark system unit
- 240W external power adapter + power cord
- Quick Start Guide / documentation
