Everything about High Bandwidth Memory

Type of memory used on processors that require high transfer rate memory

High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM), initially developed by Samsung, AMD and SK Hynix. It is often used in conjunction with performance-oriented graphics accelerators, network devices, FPGAs and ASICs; some CPUs use HBM as on-package cache or RAM, such as the NEC SX-Aurora TSUBASA and Fujitsu A64FX. The first HBM memory chip was produced by SK Hynix in 2013, and the first devices shipped with HBM were the AMD Fiji GPUs in 2015. Wikipedia →
