How SK Hynix Overtook Samsung in AI Chipmaking Stakes

TL;DR

SK Hynix has surpassed Samsung Electronics to become the world's most valuable memory chipmaker.
This success is driven by SK Hynix's High-Bandwidth Memory (HBM) chips, crucial for AI components used in data centers and cloud infrastructure.
