Asus’s ProArt P16 and P14 pair Nvidia’s ARM-based Grace CPU with Blackwell graphics and unified memory to run demanding AI models locally.
Nvidia is moving beyond its role as the dominant supplier of AI accelerators and into the Windows PC market with an ARM-based platform designed to run demanding machine-learning work locally. Asus has unveiled the ProArt P16 and P14, two creator-focused laptops that replace the usual Intel or AMD x86 processor with Nvidia’s Grace CPU and Blackwell graphics, forming what the company describes as an RTX Spark system. Asus says the machines are aimed at developers and content professionals who want to run large language models, image generation tools and AI agents on the device itself rather than in the cloud.
The key technical draw is the platform’s unified memory architecture. Asus says the laptops can be configured with up to 128GB of shared memory, giving the CPU and GPU access to the same pool of data and allowing much larger models to remain on the machine. Nvidia and Asus are promoting up to 1 petaflop of AI performance, although that figure refers to FP4 AI work rather than conventional processor throughput and is not directly comparable with standard CPU benchmarks. In practice, the design is intended to handle sustained local inference, multi-step agent tasks and creative workflows that would otherwise depend on remote servers.
The move also highlights Nvidia’s ambition to become a broader Windows platform provider, not just a chip supplier for graphics cards and data centres. According to Tom’s Hardware, the RTX Spark superchip is built around as many as 20 ARM CPU cores, a Blackwell GPU with 6,144 CUDA cores, 128GB of LPDDR5X memory and 300GB/s of bandwidth. That configuration is meant to support long-running AI tasks and very large context windows, and Microsoft, Dell, HP, Lenovo, Asus and MSI are among the partners expected to use the platform in high-end laptops and compact desktops.
For Asus, the ProArt models also remain conventional premium creator machines in form as well as function. The ProArt P16 has a 16-inch OLED panel, measures 12.9mm at its thinnest point and weighs 1.77kg, while the smaller P14 has a 14-inch display and weighs 1.48kg. Both offer up to a 120Hz refresh rate and peak brightness of 1,600 nits. Asus has also linked the devices to software partners including ComfyUI and Nous Research’s Hermes agent, underlining the company’s pitch that sensitive work can stay local and users can avoid recurring cloud costs.
