HONOR unveils Tiangong AXB35 Ultra mini-PC built with Nvidia
The two-litre machine runs large AI models locally on Nvidia’s RTX Spark chip with 128 GB of unified memory.
HONOR has presented the Tiangong AXB35 Ultra, a mini-PC built around Nvidia’s RTX Spark chip. The machine is part of the company’s Alpha Plan, unveiled at MWC 2025, to extend the brand beyond smartphones.
The chassis measures roughly two litres, at 70 × 192 × 203 mm and 1.5 kg. Inside are 128 GB of unified memory and a 2 TB SSD. HONOR claims up to one petaflop of AI compute in FP4 and cites a 300-billion-parameter model as a deployment reference. It runs Windows 11 or Ubuntu, with three power modes at 55, 85 and 132 watts and an external 240 W supply.
Two other versions share the same chassis: a Standard model with an Intel Core Ultra X7 358H and 64 GB of memory, and a Pro model with an AMD Ryzen AI Max+ 395 and 128 GB. Connectivity includes two 10GbE ports, Wi-Fi 7, two USB4, four USB-A, HDMI 2.1 and three M.2 slots.
RTX Spark is Nvidia’s own PC processor, pairing a Blackwell GPU with a 20-core MediaTek ARM Grace CPU and up to 6,144 CUDA cores. Asus, Microsoft, Lenovo and Acer are also launching machines with the chip.
