ASUS ProArt RTX Spark Hits 128GB, 120B Models [2026]

shattered.io reports that an ASUS ProArt system built around RTX Spark reaches 128 GB of unified memory and is positioned to run models with up to 120 billion parameters. The coverage highlights the combination of large shared memory, an Arm-based Grace CPU, Blackwell graphics, and NVIDIA's CUDA and RTX software stack for local AI and creator workloads. The report is product coverage, not an independent validation of those model claims.

Memory capacity can make larger models possible, but it does not determine inference speed or usability on its own. Results will depend on quantisation, context length, software frameworks, memory bandwidth, GPU utilisation, thermals, and the exact ProArt configuration. Buyers should verify storage, power limits, cooling, acoustics, ports, Windows on Arm compatibility, and support for their preferred tools before relying on the headline capacity.

For Canadian buyers, the report does not establish Canadian pricing, availability, warranty coverage, or shipping. ASUS Canada's product listing and independent testing should be checked before comparing this system with other RTX Spark PCs, x86 workstations, cloud GPU services, or Apple silicon hardware.
