HP ZGX Nano vs NVIDIA DGX Spark: Same GB10, Who Pays More

The HP ZGX Nano G1n and the NVIDIA DGX Spark are the same computer where it counts: one NVIDIA GB10 Grace Blackwell Superchip, 128 GB of unified memory at 273 GB/s, 1 petaFLOP of FP4 compute, ConnectX-7 clustering and NVIDIA DGX OS. In Singapore the difference is S$2,899 at list, with the HP ZGX Nano G1n 4 TB at S$11,499 (promotional pricing may apply, see the product page or request a quote) and the NVIDIA DGX Spark 4 TB at S$8,600. This post sets out what HP adds for that premium, where the two are identical, what the Founders Edition listing means, and which buyers should pay more for the HP. For the wider field, including the ASUS Ascent GX10 from S$7,200, start with our ASUS Agent Computer guide and the GB10 buyer's guide.

HP ZGX Nano G1n vs NVIDIA DGX Spark: specification table

Where they are identical: silicon, memory, speed and software

HP builds the ZGX Nano on NVIDIA's GB10 reference platform, the same one NVIDIA uses for the DGX Spark and ASUS uses for the Ascent GX10. The 20-core Arm CPU, the Blackwell GPU, the 128 GB of LPDDR5X on a 256-bit bus at 273 GB/s and the ConnectX-7 fabric are the same parts, and both boot NVIDIA DGX OS with the NVIDIA AI stack, CUDA, NIM and the NemoClaw agent stack. Tokens per second on a 70B model at FP4 are the same on either box within testing noise, both hold the same 200B-parameter single-unit ceiling, and two of either pool 256 GB over a QSFP cable for 405B-class models. The HP's rated storage drive, a PCIe 4.0 OPAL unit at 7,000 MB/s reads, sits in a slot StorageReview found to be PCIe 5.0 x4 electrically, but the Spark's 4 TB self-encrypting drive is the same class, so model loading is comparable. If your decision is about capability, there is no decision to make; our DGX Spark vs Ascent GX10 post makes the same point for the ASUS unit.

What HP adds: certified security and an air-gapped SKU

The HP premium buys a regulated-procurement feature list that NVIDIA does not publish for the Spark. HP's datasheet lists a TPM 2.0 that can be switched into FIPS 140-2 certified mode, a BIOS with Common Criteria EAL4+ certification, system and emergency ROM flash recovery that repairs a corrupted BIOS (the self-healing firmware protection HP markets across its Z range as Sure Start), a boot control that disables booting from removable media entirely, PXE remote boot, and a factory self-encrypting OPAL drive. The unit is TAA compliant and EPEAT Gold registered, both of which appear on government and institutional tender checklists. Most important for a classified network or a PDPA-sensitive data room, HP sells a Secure and Regulated Environments configuration of the ZGX Nano with no Wi-Fi or Bluetooth radios at all, ordered through HP sales; NVIDIA's own page lists the Spark only with Wi-Fi 7 and Bluetooth 5.4. If your security officer has to sign off a GB10 box, the HP is the one with the paperwork. Our HP ZGX Nano G1n guide covers the full list.

What HP adds: ZGX Toolkit and remote management

HP's second addition is tooling. The HP ZGX Toolkit is a free Visual Studio Code extension that runs on an x86 Windows 11 or Ubuntu 24.04 client, discovers the ZGX Nano on the network, sets up SSH key authentication in one click, and installs a chosen stack on the unit: Python, Podman, Ollama, Miniforge, nvtop and btop at the base, with uv, JupyterLab, Poetry, MLflow, Streamlit, Gradio and Open WebUI in the Python environment, plus PyTorch 2.8 or 2.9 on CUDA 12.9 or 13.0. HP quotes a 45 percent average time saving against a do-it-yourself setup, with the caveat that savings vary. The Spark ships with the same NVIDIA factory image (NVIDIA Connect, CUDA 13, DGX Dashboard, AI Workbench) and NVIDIA's step-by-step playbooks, which are excellent, but there is no vendor-supplied client-side tool; you do the SSH and package work yourself. For IT departments, HP also supports its Remote System Controller for remote setup and maintenance with KVM and virtual media down to BIOS level, with one limit worth knowing: remote power-on is not supported, so the unit must already be on. HP's Z Runtime CLI for pulling and serving models is listed for the larger ZGX Fury, not the Nano.

Acoustics, thermals and chassis

Both are 150 mm square boxes on a 240 W USB-C adapter, so the physical differences are small. The HP is 1.25 kg to the Spark's 1.2 kg and 51 mm tall before its feet. Both vendors publish noise figures, but under different standards: HP declares 22.0 dB idle and 27.6 dB sound pressure under disk load to ISO 7779, while NVIDIA declares 13 dB idle and 29 dB operating sound pressure to ECMA-109, so treat them as two quiet machines rather than ranking one above the other. StorageReview measured the HP's CPU peaking at 77.3 °C and GPU at 69 °C under sustained load, with the NVIDIA Founders Edition running warmer at the GPU in the same section of its review, and logged about 228 W peak system draw. HP rates the Nano for 5 to 30 °C ambient, which an air-conditioned Singapore office meets, and its chassis uses up to 75 percent recycled aluminium. The Spark's all-metal shell doubles as a passive heat spreader. Neither is rack-mountable.

Price, promotion and the Founders Edition note

At list the gap is S$2,899: the HP ZGX Nano G1n 4 TB is S$11,499 and the NVIDIA DGX Spark 4 TB is S$8,600. HP runs promotional pricing on the Nano that is shown on the product page; it changes, so check the page or request a quote before deciding, because at promotional levels the HP can come close to the Spark while keeping its security features. Two DGX Spark listings appear on our store at the same S$8,600: the standard unit and the Founders Edition, which is the NVIDIA-branded unit supplied with a UK-style power cord, the plug type used in Singapore. Specification and price are the same; pick the one in stock. For context, the ASUS Ascent GX10 is S$7,200 for 1 TB, S$8,050 for 2 TB and S$9,850 for 4 TB, and the MSI EdgeXpert 4 TB is S$6,895, so the HP at list is the most expensive 4 TB GB10 short of the Dell Pro Max and xFusion units. The GX10 vs ZGX Nano vs Dell Pro Max comparison ranks the whole group.

Warranty and support channel

HP's datasheet lists a one-year limited hardware warranty in most regions with optional HP Care Packs for extension, and HP states spare parts remain available during warranty and for up to five years after production ends; confirm the Singapore term and Care Pack options for your SKU when requesting a quote. The DGX Spark is supported through NVIDIA's channel; confirm its term the same way. The practical difference is the service organisation behind the box: an HP Z fleet with existing service contracts gets the Nano folded into the same support workflow, which is often the reason an enterprise picks it over the reference unit. Our HP warranty in Singapore post explains how claims work locally.

Who should pay the HP premium?

Buy the HP ZGX Nano G1n if any of these apply: your procurement requires FIPS-mode TPM, Common Criteria certification or TAA compliance; you need a radio-free, air-gapped GB10 unit; your developers want the ZGX Toolkit's one-click VS Code setup; IT wants KVM-level remote management; or your organisation already runs HP Z workstations under service contracts. Check the promotional price first, because it narrows the gap considerably. Buy the NVIDIA DGX Spark if you want the reference design at the lower list price, your tender names NVIDIA-branded hardware, or you simply want the cheapest 4 TB route into GB10 among the NVIDIA and HP units. Either way you get the same models at the same speed. If you are weighing HP against HP, our ZGX Nano vs ZGX Fury post covers the step up to the GB300 DGX Station class, and the AI hardware calculator checks that your target model fits in 128 GB before you buy either.
