NVIDIA launches RTX Spark PCs, schedules demos in six cities

NVIDIA launched RTX Spark on October 16, presenting it as a Windows PC category for creators, gamers and AI-agent workloads. For launch day, the company scheduled public hands-on events in San Francisco, Berlin, Taipei, Beijing, Istanbul and Seoul.

Microsoft said laptops from ASUS, Dell, HP, Lenovo, MSI and Microsoft Surface were available for preorder and would begin shipping October 16. RTX Spark development boxes and mini desktops were expected later in 2026.

NVIDIA and Microsoft describe the RTX Spark superchip as a combination of a Blackwell RTX GPU and a Grace CPU. The companies say configurations offer up to 6,144 CUDA cores, a 20-core CPU and 128 GB of unified memory. Microsoft says the memory is dynamically shared between the CPU and GPU, with the amount available to the GPU varying by configuration and workload.

The companies advertise up to 1 petaflop of FP4 AI performance and the ability to run models with more than 120 billion parameters locally on some configurations. Those figures remain vendor claims, not independently established results across the product line. Microsoft says the petaflop figure is theoretical and uses sparsity.

NVIDIA says the same machines support CUDA and local AI tools, hardware-accelerated creative applications, and gaming features including DLSS, Reflex, G-SYNC and ray tracing. The research for this article did not independently audit NVIDIA’s claim that hundreds of games and thousands of apps, games and models are ready for the platform.

Microsoft listed the Surface Laptop Ultra, one RTX Spark system, with a starting price of $2,599. That price does not set a minimum for the broader range of partner computers. NVIDIA said the six launch events would include creative, development, gaming and local-AI demonstrations, with entry rules varying by city.
