Key takeaways
- AMD stock jumps 7% as Nvidia shares decline
- Broadcom gains as investors reassess AI chip competition
- AMD's growing data center business strengthens investment case
Advanced Micro Devices (NASDAQ: AMD) shares surged approximately 7% on November 12 as investors turned toward competing artificial intelligence chipmakers following Nvidia CEO Jensen Huang's resignation, extending a volatile rally across semiconductor stocks.
Broadcom (NASDAQ: AVGO) gained around 5.4%, while Nvidia (NASDAQ: NVDA) fell approximately 4% in a later Thursday trading snapshot. The divergence suggests investors are reassessing competitive risks across the AI hardware industry rather than abandoning semiconductor stocks altogether.
The moves followed confirmation that Huang had stepped down after 33 years leading Nvidia, with Chief Financial Officer Colette Kress appointed interim CEO. His departure came after an independent board investigation and intensified uncertainty surrounding the company's leadership.
Why Is AMD Stock Up Today?
AMD's rally reflects growing investor interest in alternative suppliers of AI accelerators and data-center processors following Nvidia's leadership change.
The development follows the earlier Nvidia board investigation, which prompted concerns about corporate governance, executive succession and the company's ability to maintain its competitive position.
However, Thursday's share-price divergence does not establish that Nvidia customers are canceling orders or switching suppliers.
AMD entered the session with considerable momentum of its own. Shares closed November 11 at $552.90, gaining 7.32% during that session, after advancing more than 13% on November 9.
Its recent Google Cloud partnership provides another catalyst, with AMD EPYC processors selected to support Google's TPU 8tx AI infrastructure.
The arrangement demonstrates how AMD can benefit from AI investment even when customers use proprietary accelerators instead of its GPUs.
AMD's AI Data Center Revenue Nearly Doubles
The market rotation comes as AMD's financial results provide a stronger foundation for its Nvidia challenge.
According to AMD's November 3 earnings release, third-quarter revenue increased 45% year over year to $13.38 billion.
Data-center revenue climbed 97% to $8.55 billion, driven by EPYC server processors and Instinct MI450 AI accelerators.
The performance follows an earlier AMD earnings rally, which highlighted accelerating enterprise and hyperscaler demand.
AMD expects fourth-quarter revenue of approximately $17 billion, plus or minus 3%, implying roughly 66% annual growth at the midpoint.
CEO Lisa Su has also outlined an ambitious expansion strategy centered on the company's Helios rack-scale computing systems and ROCm software ecosystem.
AMD identifies Anthropic, Microsoft, Meta, OpenAI and Oracle among customers running workloads on early Helios systems.
Its partnership with Anthropic includes plans to deploy up to two gigawatts of Instinct MI450 GPUs, with initial large-scale deployment scheduled for 2027.
Can AMD and Broadcom Challenge Nvidia's Dominance?
Despite AMD's improving fundamentals, Nvidia remains deeply embedded in AI infrastructure through its GPU architecture, CUDA software platform and relationships with major cloud providers.
Broadcom represents another competitor, particularly in custom AI accelerators and networking infrastructure.
The divergence follows an earlier split across major technology stocks, when cloud companies advanced despite weakness in Nvidia.
However, rapid gains also raise valuation questions.
The semiconductor sector has experienced a substantial compression in earnings multiples, reflecting concerns about whether infrastructure spending can generate sustainable profits.
