NVIDIA RTX Spark integrates CPU and GPU with 128GB unified memory

By PulseAugur Editorial · [1 sources] ·

NVIDIA has unveiled its RTX Spark superchip, designed for on-device AI agents and set to ship in the fall of 2026. This chip integrates a 20-core Grace CPU with a Blackwell RTX GPU, featuring a shared 128GB unified memory pool accessible via NVLink-C2C. This architecture eliminates the need for data copying between CPU system RAM and GPU VRAM over the PCIe bus, significantly improving performance for large AI models that exceed discrete GPU memory. AI

IMPACT This unified memory architecture could significantly boost on-device AI performance by eliminating data transfer bottlenecks for large models.
