What is HBM?

High Bandwidth Memory (HBM) is a high-performance computer RAM standard for 3D-stacked DRAM. It's used in conjunction with high-performance graphics accelerators, network devices, and high-performance computing. HBM offers significantly higher bandwidth and lower power consumption compared to older technologies like DDR4 or GDDR5 by stacking multiple DRAM dies and connecting them with through-silicon vias (TSVs).
