Nowadays, bandwidth-hungry devices, like ultra-high-end compute GPUs or FPGAs use 4-6 HBM2E memory stacks. With SK Hynix's HBM2E, such applications can get 1.84-2.76 TBps of bandwidth (usually lower because GPU and FPGA developers are cautious). With HBM3, these devices could get at least 2.66-3.99 TBps of bandwidth, according to the company.SK Hynix did not share an expected availability date. It's not expected soon as there is no HBM3 specification yet. JEDEC still needs to outline the industry standard.
