On June 1, Advanced Micro Devices (AMD) fell 3.59% in regular trading, trading at $493.924/share, with trading volume of $30.29 billion. The decline was triggered by NVIDIA and Microsoft jointly unveiling a new ARM-based AI PC chip, directly challenging AMD's longstanding x86 PC processor dominance.
The new chip, reportedly dubbed N1X, features TSMC 3nm process, ARM v9.2 architecture with 20-core heterogeneous design, a Blackwell GPU comparable to RTX 5070, and AI computing power of 180-200 TOPS. The product combines NVIDIA GPU, MediaTek CPU, and Windows system integration, breaking the x86 duopoly that Intel and AMD have maintained for decades and ending Qualcomm's exclusive position in Windows-on-ARM.
The semiconductor sector showed sharp divergence: ARM Holdings surged 13.88%, NVIDIA gained 3.87%, while Intel fell 2.99%. Analysts note AMD faces pressure on high-end gaming and creator PC market share, with mid-to-low-end segments further squeezed. However, Barclays raised its AMD price target from $500 to $665, maintaining an outperform rating, suggesting AMD's data center and AI compute strengths provide a deeper competitive moat against this PC-centric disruption.
