Nvidia just walked into Intel and AMD’s house and rearranged the furniture. The company unveiled its RTX Spark Superchip at Computex in Taipei on June 1, an Arm-based processor designed for Windows PCs that integrates both CPU and GPU functions on a single chip.
The market’s verdict was swift and decisive. Nvidia shares climbed roughly 1.7% in pre-market trading, while Intel dropped nearly 6% and AMD fell about 5%.
What Nvidia actually built
The RTX Spark Superchip uses what Nvidia calls its N1X architecture, built on Arm chip design rather than the x86 instruction set that Intel and AMD have relied on for decades. The chip combines processing and graphics capabilities into a single package, which Nvidia CEO Jensen Huang described as “the most efficient PC chip ever built.”
Nvidia collaborated with Microsoft and MediaTek on the superchip’s development, a partnership that addresses two critical challenges: ensuring Windows software runs smoothly on Arm architecture, and leveraging MediaTek’s manufacturing expertise in mobile-class processors.
