Samsung Electronics has shipped the world's first commercial HBM4 memory, a critical advancement for AI computing demanding extreme data throughput. This new generation delivers 11.7 gigabits-per-second (Gbps) performance, a 46% increase over the previous HBM3E standard, directly addressing the escalating data bottlenecks in large-scale AI model training and inference.

Samsung's HBM4 achieves this speed while significantly improving power efficiency by 40% through advanced low-voltage TSV technology and optimized PDN design, reducing thermal resistance by 10% and enhancing heat dissipation by 30% compared to HBM3E. This combination of raw speed and efficiency positions HBM4 as the essential memory solution for next-generation AI accelerators and high-performance computing systems.
