Nvidia debuts RTX Spark superchip for Windows laptops, combining Blackwell GPU and Arm-based Grace CPU to compete with Intel and AMD.

Nvidia unveiled the RTX Spark during its GTC Taipei event. The chip will power laptops from ASUS, Dell, HP, and Microsoft starting this fall, and will also be available in small desktops. The RTX Spark combines a Blackwell GPU and Grace CPU.

The RTX Spark will pack upward of 128GB of memory and notebooks using the chip will be roughly 14 millimeters thick with HD webcams and all-day battery life. Because it uses an Arm-based processor (a different CPU architecture than the x86 chips from Intel and AMD that most software is built on), Nvidia is working with Microsoft and software developers to ensure programs can run on the chip.

Nvidia has not announced pricing but noted that the first systems will target the premium market, while less powerful versions with less memory will be offered for lower-priced notebooks. Gaming on Arm-based chips poses potential issues, and if the RTX Spark cannot run the games players want, it will be difficult to sell.
