Nvidia built a laptop chip with an Arm CPU, Blackwell GPU, and 128GB of RAM
Twenty Arm CPU cores. A Blackwell-class GPU with 6,144 CUDA cores. Up to 128GB of LPDDR5X memory shared across both, connected over NVLink-C2C at 300 GB/s. The whole thing runs at 80W.
Key Takeaways
- RTX Spark pairs a 20-core Arm CPU co-designed with MediaTek and a Blackwell-class GPU with 6,144 CUDA cores
- Up to 128GB LPDDR5X unified memory at 300 GB/s bandwidth, enough to run a 70B parameter AI model locally
- The whole package runs at 80W and claims 1 petaflop of FP4 AI performance
- First machines ship autumn 2026 from Microsoft, ASUS, Dell, HP, Lenovo, and MSI
