The H3C MegaCube has officially landed, and it’s not your average palm-sized desktop. With a bold design, Nvidia’s cutting-edge GB10 chipset, and 128 GB of LPDDR5X RAM under the hood, this mini-PC is built for serious AI tasks—despite being no bigger than a stack of books.
H3C MegaCube mini-PC pushes high performance limits
At just 150 × 150 × 50.5 mm, the MegaCube looks sleek and minimal on the outside. Internally, though, it’s a different story. This compact unit pairs ten ARM Cortex-X925 cores with ten Cortex-A725 cores, topped off with a Blackwell-based GPU boasting 6,144 CUDA cores. Combined, they offer up to 1 petaflop of FP4 Tensor performance, at least in theory.
This same GB10 platform also powers larger systems like MSI’s EdgeXpert AI. However, H3C is aiming to bring that same level of acceleration to smaller, space-saving setups.

H3C MegaCube mini-PC includes 128 GB RAM and 10 Gbps Ethernet
Even more impressive than the processing power is the spec sheet. Every MegaCube packs 128 GB of LPDDR5X RAM, a 10 Gbps Ethernet port, WiFi 7, USB-C, and HDMI 2.1a support. It also runs on Nvidia’s DGX OS, which is based on Ubuntu and tuned for AI workflows.
If one unit isn’t enough, two MegaCubes can be paired together for even more processing bandwidth. That modular capability, paired with ultra-fast connectivity, makes it suitable for developers, researchers, or AI engineers who don’t have room for full-size workstations.
What the H3C MegaCube offers at a glance
Here’s what the MegaCube brings to the table:
- Nvidia GB10 chipset (Blackwell-based GPU with 6,144 CUDA cores)
- 20-core ARM CPU (10 Cortex-X925 + 10 Cortex-A725)
- 128 GB LPDDR5X RAM
- 10 Gbps Ethernet + WiFi 7
- USB Type-C and HDMI 2.1a
- DGX OS pre-installed
It’s built for speed, but it’s also designed to slot seamlessly into modern, minimal desk setups.
Price puts the MegaCube in premium territory
This kind of performance doesn’t come cheap. The MegaCube is currently listed at CNY 36,999, or around $5,240 USD, on JD.com. That price tag positions it squarely in the high-end AI hardware segment, near machines like the DGX Spark.
Still, for users chasing performance in a compact form factor, the MegaCube could be worth the premium—especially if space is tight but power is non-negotiable.
Small shell, sharp edge
With its polished exterior and heavy-hitting internals, the MegaCube isn’t just another box on the desk. It’s a precision-built tool aimed at serious work, and it proves you don’t need a tower to go full throttle.
