History

Historical Context

In 2015 AMD’s Fiji GPU became the first product to use SK Hynix’s first HBM chip, proving stacked memory could feed data-hungry graphics and early AI workloads. JEDEC later ratified HBM4 in April 2025, delivering up to 2,048 GB/s per stack. Nvidia’s 2024 $500 billion AI pact with SK Group secures that HBM4 supply for its Vera Rubin chips, extending the 2015 shift toward high-bandwidth memory.
