Marvell’s 311% Surge and AMD’s HBM Partnership Highlight AI Chip Competition
AMD•SK Hynix’s bet on high-bandwidth memory with AMD since 2014 positioned AMD to capitalize on surging AI data-center demand following the 2022 ChatGPT release. Marvell’s 311% rally from June 2025 to June 2026 reflects its AI-first data center pivot and secured three-nanometer custom XPU capacity, intensifying competition in AI chips.
1. AMD's Role in HBM Chip Development
AMD partnered with SK Hynix to launch the world’s first high-bandwidth memory (HBM) chips in 2014, supplying critical early design inputs and securing priority access to HBM capacity. This partnership positioned AMD to leverage the explosion in AI data-center demand that followed the release of large language models like ChatGPT in 2022.
2. Marvell's Custom AI Silicon Surge
Marvell Technology achieved a 311% share price increase from June 2025 to June 2026 by transforming into an AI-centric data center semiconductor company, with its data center segment accounting for 75% of revenue. The company secured three-nanometer wafer and advanced packaging capacity for custom XPU programs, signaling heightened competition for AMD in next-generation AI accelerators.
