DGX Spark vs ASUS Ascent GX10: Same GB10, Which to Buy (SG)

The NVIDIA DGX Spark and the ASUS Ascent GX10 are the same computer on the inside: one NVIDIA GB10 Grace Blackwell Superchip, 128 GB of unified LPDDR5X memory at 273 GB/s, 1 petaFLOP of FP4 compute, ConnectX-7 networking and NVIDIA DGX OS. What differs is the box, the storage tiers, the port details, the weight, the warranty channel and the price: in Singapore the GX10 starts at S$7,200 with 1 TB, while the DGX Spark is sold as a single 4 TB configuration at S$8,800. This post puts the two side by side and gives a plain recommendation for developers, research groups and IT departments. For the full ASUS line-up from NUC to DGX Station, start with our ASUS Agent Computer guide.

DGX Spark vs Ascent GX10: specification table

Same silicon, same software, same speed

NVIDIA designed the GB10 platform and named ASUS among its launch partners, so the Ascent GX10 is one of the official implementations of the DGX Spark, not an imitation. Both run the identical Superchip at the same memory bandwidth, boot the same NVIDIA DGX OS, and take the same CUDA, PyTorch, TensorRT, NIM and Ollama stack without modification. Independent testing by StorageReview found the ASUS unit tracking the NVIDIA Founders Edition closely across its vLLM serving sweeps. If your decision hinges on tokens per second, there is no decision to make: a 70B model at FP4 generates at the same rate on either box, and both top out at roughly 200 billion parameters in a single unit. The DGX Spark documentation, container images and NVIDIA Sync clustering tools apply to the GX10 unchanged; our DGX Spark setup and enterprise deployment guide works for both.

Storage tiers: 1, 2 or 4 TB vs 4 TB only

This is the biggest practical difference and the one that drives price. NVIDIA's documentation lists the DGX Spark with 1 TB or 4 TB of self-encrypting NVMe, but the configuration available in Singapore through SourceIT is the 4 TB unit at S$8,800 (a Founders Edition variant with a UK-style power cord is listed at the same price). ASUS offers three tiers. The GX10 1 TB at S$7,200 is the cheapest entry into the GB10 ecosystem locally and enough for a developer keeping one or two 70B checkpoints. The GX10 2 TB at S$8,050 is the default for a model library and still undercuts the Spark. The GX10 4 TB at S$9,850 matches the Spark on capacity. Compute and memory are identical across all three, so you are paying only for NVMe. If 4 TB is the target, the DGX Spark is cheaper by S$1,050; if 1 TB or 2 TB is enough, the GX10 saves S$1,600 or S$750 against the only Spark configuration on sale.

Ports, chassis, cooling and weight

Both systems expose four USB-C ports at 20 Gbps, one HDMI 2.1-class output, a 10 GbE RJ-45 and two QSFP cages for clustering. The GX10's USB-C ports carry DisplayPort 2.1 alt-mode, which is how ASUS reaches five 4K displays from a box this size, and its HDMI is the 2.1b revision against the Spark's 2.1a. One GX10 port also accepts up to 180 W of USB Power Delivery input, so the unit can run from a compliant high-wattage PD source, although the bundled 240 W adapter is the normal supply; the Spark draws its 240 W through one of its four USB-C ports. On a developer desk the differences are small; on a shelf of eight units, PD-in flexibility and the GX10's Kensington slot can matter.

The DGX Spark is the lighter machine at 1.2 kg, with an all-metal alloy shell that acts as a passive heat spreader and a gold-speckled finish. The GX10 weighs 1.48 kg because ASUS fitted a dual-fan cooler with seven-level fan control and five heat pipes, including an 8 mm pipe, and claims 1.6 times the thermal coverage of comparable compact systems. Both hold their performance under sustained load; StorageReview's heat-soak testing had the ASUS holding its results after an hour. The GX10's magnetic footpads align two or four units side by side for clustering, and its industrial design picked up Red Dot, iF and Taiwan Excellence awards in 2026, a minor point for an engineer and a real one for a reception desk or a tender that scores design quality.

Clustering two or four units

Because both carry ConnectX-7, two units of either type connect directly over a QSFP direct-attach cable to pool 256 GB of memory, enough for Llama 3.1 405B-class and Qwen3-235B-class models. NVIDIA's Sync Cluster Assistant supports up to four units, or 512 GB, through an external switch. SourceIT stocks the ASUS QSFP cable for the GX10 (40 cm, S$120) and the NVIDIA QSFP112 400G DAC cable (40 cm, S$155). Mixing a Spark with a GX10 is possible on paper since the fabric and OS are the same, but we recommend matched units so DGX OS versions, firmware and support stay in step. For a budget-constrained research group, two GX10 1 TB units at S$14,400 are the cheapest route to 405B-class inference in Singapore; two Sparks are S$17,600.

DGX Spark or Ascent GX10: which should you buy?

Buy the ASUS Ascent GX10 if you want the lowest entry price into GB10 (S$7,200), if 1 TB or 2 TB is enough, if you are buying several units and the per-unit saving compounds, if you want the official ASUS Singapore warranty alongside ASUS NUCs and monitors already in the fleet, or if the design awards and DisplayPort 2.1 multi-monitor output are useful. Education and NVIDIA Inception pricing may apply under ASUS's programme, and ASUS validates NemoClaw, OpenClaw and Hermes Agent on the GX10, which we cover in the Ascent GX10 guide.

Buy the NVIDIA DGX Spark if you need 4 TB and want the cheaper 4 TB unit (S$8,800 vs S$9,850), if your organisation standardises on NVIDIA-branded hardware for procurement or support reasons, if you want the lighter 1.2 kg unit for travel between sites, or if the reference design is written into a tender specification. Support runs through NVIDIA's channel; confirm the warranty term for your SKU when requesting a quote. Either way you get the same models, speed and DGX OS; the choice is about storage, price, channel and chassis, not capability. If your models exceed 200B parameters on one box or a whole team will share the endpoint, look at the ASUS ExpertCenter Pro ET900N G3 DGX Station instead.

Frequently asked questions

Is the ASUS Ascent GX10 faster or slower than the DGX Spark? Neither. Both use the same NVIDIA GB10 Superchip, 128 GB of memory at 273 GB/s and DGX OS, so inference and training performance are the same within testing noise.

Why is the GX10 cheaper than the DGX Spark? Because ASUS sells 1 TB and 2 TB tiers. At the same 4 TB capacity the DGX Spark is cheaper at S$8,800 against S$9,850 for the GX10.

Can I cluster a DGX Spark with an Ascent GX10? Both use ConnectX-7 and the same DGX OS, so the fabric is compatible, but we recommend matched units so firmware and support stay aligned.

Which one runs Windows? Neither. Both run NVIDIA DGX OS, an Ubuntu-based Linux. You work from any laptop over the network or connect a display for a local desktop.

What is the difference in ports? Both have four 20 Gbps USB-C ports, HDMI, 10 GbE and two QSFP ports. The GX10 adds DisplayPort 2.1 alt-mode on USB-C, HDMI 2.1b and a USB-C port that accepts 180 W USB-PD input.

Which is better for a university lab in Singapore? Usually the GX10: the lower entry price compounds across multiple units, ASUS offers education and NVIDIA Inception pricing, and the warranty is handled locally by ASUS Singapore.

What warranty do they carry? The GX10 carries the official ASUS Singapore warranty; DGX Spark support runs through NVIDIA's channel. Confirm the term for your SKU when requesting a quote.
