Intel and AMD shares fall as Nvidia rises on new PC superchip announcement

Nvidia just crashed the PC processor party that Intel and AMD have been hosting for decades. The company unveiled its RTX Spark Superchip at Computex in Taipei on June 1, sending rival chipmakers’ stocks in opposite directions and signaling what could be the most significant shake-up in personal computing since Apple ditched Intel for its own silicon.

Pre-market trading told the story in real time. Intel and AMD shares fell, while Nvidia climbed roughly 2%. MediaTek, Nvidia’s development partner on the chip, gained over 5%. Arm Holdings, whose architecture underpins the new processor, rose more than 7%.

What the RTX Spark Superchip actually is

The RTX Spark is an Arm-based design that integrates both a microprocessor and a graphics processor onto one chip. It was co-developed with MediaTek, a Taiwanese semiconductor company. Nvidia CEO Jensen Huang framed the chip as a way to modernize PCs for the AI era, with the pitch centering on AI-optimized computing and dedicated hardware for running AI models locally.

Systems powered by the RTX Spark are expected to hit shelves in fall 2026, with Dell and Lenovo among the manufacturers confirmed to offer devices built around the new chip.

Why this threatens Intel and AMD’s core business

Intel and AMD have built their PC empires on x86 architecture, a processor design that dates back to the late 1970s. Nvidia’s chip uses Arm architecture instead, the same family of designs that powers virtually every smartphone and Apple’s Mac lineup.

Reports surfaced on May 30 that Nvidia and Microsoft were preparing to debut Windows PCs powered by Nvidia chips the following week. Qualcomm has also been pushing Arm-based Windows chips, meaning Intel and AMD could soon face competition from multiple directions simultaneously.

What this means for investors

For Intel and AMD investors, the risk isn’t that Nvidia captures the entire PC market overnight. It’s that Nvidia captures the highest-margin segment: AI-optimized premium laptops and desktops where buyers are willing to pay more for cutting-edge capabilities.

Watch the fall 2026 launch window closely. The real test isn’t whether Nvidia can build the chip. It’s whether software developers optimize for it, whether enterprise buyers adopt it, and whether the performance and compatibility story holds up against decades of x86 ecosystem advantages.
