KitGuru was invited to an event hosted by TAITRA, Taiwan’s national trade and export body, which took place at Westfield Shopping Centre in Shepherd’s Bush. The showcase focused on smart and healthy living, highlighting advances in AI technologies, healthcare, mobility, and sustainable solutions from some of Taiwan’s most innovative and award-winning companies. However, among the exhibits, Gigabyte drew our attention with a compact system it describes as a ‘personal AI supercomputer' – the AI TOP ATOM. Measuring just one litre in volume and weighing around 1.2 kg, the unit houses NVIDIA’s new Grace Blackwell GB10 Superchip, pairing a 20-core Arm CPU with Blackwell GPU technology in a single integrated package.
According to Gigabyte’s technical sheet, the AI TOP ATOM delivers up to 1 petaFLOP of AI performance and features 128GB of unified LPDDR5x system memory on a 256-bit interface with 273 GB/s bandwidth. Storage options extend up to 4TB of PCIe Gen5 NVMe SSD, while connectivity includes USB 3.2 Gen 2×2 ports, HDMI 2.1a, Wi-Fi 7, Bluetooth 5.3, and a 10GbE RJ-45 port. Networking is further enhanced by an NVIDIA ConnectX-7 SmartNIC, offering high-speed interconnect capabilities and potential multi-unit clustering.

The system runs NVIDIA’s DGX OS, based on Ubuntu Linux, and supports the AI TOP Utility, designed to simplify local model training and inference workflows. Gigabyte claims the unit can handle models of up to 200 billion parameters standalone or around 405 billion parameters when connected to a second device.
Unlike conventional desktops, the AI TOP ATOM does not use a standard DC or IEC power connector. Instead, it draws up to 240W through USB Power Delivery 3.1, marking one of the first commercial AI systems to rely entirely on USB-based charging. Cooling and acoustic behaviour weren’t publicly demonstrated, but the compact chassis suggests laptop-class thermals with a focus on low-noise operation.
Gigabyte representatives indicated that the AI TOP ATOM is not expected to be a high-volume product, but a strategic platform aimed at education, research, and modelling companies—organisations seeking local compute power without the cost or compliance limitations of cloud infrastructure.
The device also reflects Gigabyte’s deep experience with small-form-factor design. The company was once Intel’s closest NUC partner, producing many of the most refined compact PCs in that range. That expertise has now been channelled into a new generation of AI-focused edge systems.

UK retailers including Scan and CCL list the AI TOP ATOM for pre-order at around £3,649–£3,799, with shipments expected to begin in mid-November 2025. Global pricing appears to start around US $3,499 for a 1TB configuration, rising to US $3,999 for the 4TB model.
While the quoted 1 petaFLOP rating is almost certainly a theoretical peak, the combination of Arm efficiency, NVIDIA’s Grace-Blackwell integration, and unified memory architecture marks a notable shift in what desktop AI computing can look like. When we spoke to people familiar with the market, we were told that the number one application/sales channel for a product like this will be into the education channel.
KitGuru says: The Gigabyte AI TOP ATOM stands as an early example of how AI-class compute is moving from data centres to desks. For researchers, educators, and developers working with large models, the idea of carrying a petaFLOP-capable system in a one-litre form factor would have seemed implausible only a few years ago. Whether such devices become commonplace remains to be seen, but this first UK showing demonstrates how Taiwan’s technology sector continues to blend engineering efficiency with AI-driven innovation.
