Nvidia has revealed detailed specifications of the RTX Spark Superchip — a system-on-chip designed for Windows 11 PCs capable of running AI models with up to 120 billion parameters locally. The chip combines a 20-core Grace CPU and a Blackwell GPU with 6,144 CUDA cores, connected via NVLink and paired with up to 128 GB of unified LPDDR5X memory.

At an 80W TDP, the GPU delivers performance comparable to a mobile GeForce RTX 5070 and supports DLSS 4.5. Laptops powered by RTX Spark will launch this fall starting at €2,700. For enterprise developers, Nvidia is also preparing the DGX Station for Windows workstation, built on the GB300 Grace Blackwell Ultra with 750 GB of unified memory.
