NVIDIA Unveils RTX Spark Superchip: 1 Petaflop of FP4 AI Power for Next-Gen PCs
nvidia · x · 2026-08-06
NVIDIA has officially announced the RTX Spark Superchip, integrating a Blackwell RTX GPU and a Grace CPU into a single chip designed for slim laptops and compact desktops.
Key Specs & Features:
- Performance & Memory: Delivers up to 1 Petaflop of FP4 AI performance with up to 128 GB of unified memory.
- Configuration: Features up to 6,144 Blackwell RTX GPU cores and a 20-core Grace CPU.
- Native CUDA: Runs the standard CUDA stack natively, allowing developers to prototype, fine-tune, and run inference on the latest models locally.
- Efficiency: Billed as the most power-efficient RTX chip ever made, offering all-day battery life.
NVIDIA emphasizes that the chip is built for AI agents, turning PCs into active teammates that can run tasks, generate assets, and write code autonomously. It also heavily boosts creative workflows (AV1 encode/decode, 4:2:2 hardware support) and high-end gaming (Ray Tracing, DLSS).
