Overview
- Nvidia announced the RTX Spark at its Computex keynote on Monday, presenting a single SoC that combines a 20‑core Grace ARM CPU with a Blackwell GPU that has 6,144 CUDA cores and NVLink connectivity.
- The company says the chip delivers up to 1 petaflop of AI compute and supports up to 128GB of unified LPDDR5X memory so devices can run large language models and long context windows locally.
- Microsoft and MediaTek are listed partners and major PC makers including Microsoft Surface Dell HP Lenovo ASUS MSI Acer and Gigabyte plan to ship RTX Spark laptops and compact desktops this fall.
- Nvidia and Microsoft announced new Windows security primitives and Nvidia’s OpenShell runtime to limit what on‑device agents can access but neither firm published independent performance benchmarks or final pricing.
- Analysts say the move could reshape Windows PCs if claims hold but warn execution risks include app compatibility with Windows on Arm emulation battery and thermal tradeoffs and supply and manufacturing details.
