The GB10 workstation market continues to surprise with its unprecedented popularity, with systems from multiple vendors selling almost as fast as they can be produced. HP, leveraging its established presence in the corporate computing space, has entered this burgeoning market with the ZGX Nano G1n, a compact AI workstation built on NVIDIA's GB10 platform. This review takes a deep dive into HP's implementation, examining how it stacks up against other GB10 systems and what it brings to the table for developers and enterprises.

HP ZGX Nano G1n: Key Specifications

The ZGX Nano G1n represents HP's foray into the standardized AI workstation space, maintaining the core GB10 specifications while adding HP's enterprise support and services ecosystem. The system is built around NVIDIA's GB10 Superchip, which combines:

• 10x Arm Cortex-X925 performance cores
• 10x Arm Cortex-A725 efficiency cores
• NVIDIA Blackwell GB20B GPU with 48 SMs
• 128GB LPDDR5X-8533 soldered memory
• 4TB PCIe Gen4 x4 M.2-2242 TLC SSD

The system measures just 150mm x 150mm x 51mm (5.91 x 5.91 x 2.01 inches), making it remarkably compact at just over 1 liter in volume. Weighing 1.25kg (2.76 lbs), it's designed for deployment in space-constrained environments without sacrificing performance.

Design and Build Quality

HP's implementation of the GB10 concept follows a familiar black box design, consistent with other systems in this category. The front panel is dominated by a mesh design for ventilation, with HP's branding including both their main logo and the "AI Helix" logo. A notable design choice is the inclusion of an internal LED that clearly indicates when the system is powered on—a feature not present in all GB10 implementations.

The rear panel houses all the connectivity options:

• 4x USB-C 20Gbps (Gen 2×2) with DisplayPort Alt Mode
• 1x HDMI 2.1a
• 1x 10GbE (RJ45)
• 2x 200GbE (OSFP112)
• System power button
• Wi-Fi 7 (2×2) + Bluetooth 5.4 (internal)

HP's labeling of the USB-C ports is particularly noteworthy, with the USB-IF's current generation logo clearly identifying each port as a 20Gbps connection. The left-most port features a power logo indicating it serves as the system's power input—a helpful distinction since all USB-C ports are physically identical.

Networking Capabilities

One of the standout features of the GB10 platform is the inclusion of a high-performance NVIDIA ConnectX-7 NIC, and the ZGX Nano G1n is no exception. The system features:

• 10GbE port for general networking
• Pair of 200Gbps QSFP112 ports for high-speed interconnects
• Integrated Wi-Fi 7 + Bluetooth 5.4

The ConnectX-7 NIC is arguably the marquee feature of these systems, providing the bandwidth needed for scale-out configurations. However, there's an important architectural consideration: 200Gbps networking requires a PCIe 5.0 x8 connection for optimal performance, but the GB10 platform can only provide PCIe 5.0 root ports with at most a x4 connection. As a result, the NIC is connected to a pair of x4 ports, providing the same aggregate bandwidth as an x8 connection but with some network topology restrictions.

This design approach enables developers to create multi-node clusters using the GB10 systems, with the most common setup being a two-way configuration using a single cable with 200Gbps of bandwidth between systems. With a suitable network switch, it's possible to scale clusters to several machines, providing a development environment that closely mirrors larger-scale deployments.

Power and Thermal Design

The ZGX Nano G1n utilizes a 240W external USB-C power adapter from Delta Electronics. HP has opted for a low-profile adapter that is shorter but deeper, squared off to complement the system's aesthetic. This power supply is consistent across the GB10 ecosystem, providing sufficient power for the system's components while maintaining the compact form factor.

Thermal management follows a front-to-back cooling design, with intake vents at the front and exhaust vents toward the top of the chassis. The system is elevated by four rubber feet, which also help with stability and airflow underneath. The cooling design is adequate for the system's thermal requirements, though in high-load scenarios, the compact size does mean that thermal throttling could become a consideration in poorly ventilated environments.

Performance Expectations

While the provided content doesn't include specific benchmark results, we can make some educated predictions based on the GB10 platform's capabilities. The system should deliver strong performance in AI workloads, particularly those optimized for NVIDIA's Blackwell architecture. With 1 PFLOP of FP4 AI performance, the ZGX Nano G1n is well-suited for:

• AI model training and inference
• Data preprocessing and analysis
• Computer vision applications
• Natural language processing

The 128GB of LPDDR5X memory provides ample capacity for most AI workloads, though memory-intensive applications might benefit from the larger configurations available in some GB10 variants. The 4TB SSD offers sufficient storage for datasets and models, though users with larger storage requirements might need to consider external solutions or network-attached storage.

Enterprise Integration and Support

Where HP's ZGX Nano G1n differentiates itself from other GB10 systems is in its enterprise support ecosystem. For organizations already using HP's corporate products, the ability to source AI workstations from the same vendor as their laptops and desktops simplifies procurement and support processes.

The system ships with NVIDIA DGX OS, which is optimized for AI workloads and provides a stable foundation for development. HP's corporate relationships also mean that IT departments can leverage existing support contracts and service agreements, potentially reducing the total cost of ownership compared to solutions from vendors without established enterprise channels.
