SK Hynix announces HBM3 memory with 819GB/s bandwidth per unit – Computer – News

SK Hynix has completed development of the first HBM3 memory modules. This memory will provide a bandwidth of up to 819 GB/s per unit. This is an improvement over HBM2E, which has a maximum bandwidth of 460 GB/s.

SK Hynix reported They will provide HBM3 modules in two different capacities. The company comes with modules of 24 GB and 16 GB, which respectively consist of “clusters” of twelve and eight 16 Gigabit layers. These layers are related to tsv’s It used a 1024-bit memory bus.
