Intel, SK Hynix advance chip packaging partnership with 2.5D EMIB for HBM

SK Hynix is testing Intel's advanced 2.5D EMIB (Embedded Multi-die Interconnect Bridge) technology for HBM (High Bandwidth Memory) integration, addressing the packaging bottleneck that constrains GPU-AI accelerator scaling. The reported partnership sent SK Hynix shares to all-time highs, signaling market confidence in a breakthrough that could ease supply constraints for data center accelerators.

EMIB packaging allows tighter die-to-die connections than traditional chiplet bonding, reducing latency and power loss on GPU-memory pathways—critical for LLM inference clusters where bandwidth efficiency drives total-cost-of-ownership.
