How SK Hynix Overtook Samsung in AI Chipmaking Stakes - AI Magazine

SK Hynix has overtaken Samsung Electronics to become the world's most valuable memory chipmaker, emerging from a severe debt crisis. This shift is largely attributed to its dominance in high-bandwidth... Read original →

SK Hynix’s rise stems from betting early on AI’s heterogeneous architecture, where its TSV and hybrid bonding processes lead Samsung by at least one generation—directly enabling NVIDIA’s Blackwell efficiency gains and forcing TSMC to prioritize CoWoS capacity for HBM3E. While U.S. CHIPS Act subsidies boost domestic packaging, they heighten Korean firms’ exposure to American policy shifts; SK’s Nasdaq listing is a strategic hedge. Samsung will likely accelerate 3nm GAA-based DRAM R&D and lobby with Micron to ease EUV export controls. Within 18 months, the HBM4 standard will ignite a new battleground, yet yield constraints in advanced packaging will likely cap second-tier players below 5% market share, driving further industry consolidation.
