NVIDIA has officially entered the Windows on Arm personal computer market with the announcement of its RTX Spark platform, featuring the N1X and N1 processors. Developed in partnership with MediaTek, this new hardware solution unifies a high-performance central processing unit (CPU) and graphics processing unit (GPU). The architecture targets ultrathin laptops and mini PCs, competing directly against established offerings from AMD, Intel, and Qualcomm.
Manufactured on TSMC’s 3-nanometer process, the silicon contains 70 billion transistors. The design integrates a Grace CPU configuration with up to 20 cores, splitting workloads between ten Arm Cortex-X925 performance cores and ten Cortex-A725 efficiency cores. For graphics, it features an RTX Blackwell GPU equipped with 6,144 CUDA cores. This combination delivers one PetaFLOPS of artificial intelligence performance utilizing the FP4 data format, with graphical capabilities estimated to equal a GeForce RTX 5070 Mobile GPU.
The platform relies on a unified memory architecture supporting up to 128 GB of LPDDR5X memory, operating at a bandwidth of 300 GB/s via NVLink C2C interconnect technology. It incorporates five PCIe Gen 5 lanes. Optimized for generative AI workloads, the chip executes AI models with up to 120 billion parameters and a one-million-token context window locally. NVIDIA collaborated with Microsoft to optimize Windows for agentic AI applications.
Performance metrics highlighted by the manufacturer include rendering 3D scenes up to 90 GB, editing 12K resolution video files, and running mainstream video games at 100 frames per second at 1440p resolution. The GPU natively supports ray tracing and DLSS technologies. Hardware partners showcased concept designs measuring 14 millimeters in thickness featuring Tandem OLED G-SYNC displays, emphasizing all-day battery life.
NVIDIA confirmed a multi-year roadmap, planning the “Vera Rubin” generation for 2028 and the “Rosa Feynman” platform for 2029. Commercial laptops from manufacturers like Acer, ASUS, Dell, HP, Lenovo, and Microsoft are scheduled to debut in the autumn, though official consumer pricing has not yet been disclosed.
