HBM3 to Top 665 GBps Bandwidth per Chip, SK Hynix Says

While high bandwidth memory (HBM) has yet to become a mainstream type of DRAM for graphics cards, it is a memory of choice for bandwidth-hungry datacenter and professional applications. HBM3 is the next step, and this week, SK Hynix revealed plans for its HBM3 offering, bringing us new information on expected bandwidth of the upcoming spec. 

SK Hynix’s current HBM2E memory stacks provide an unbeatable 460 GBps of bandwidth per device. JEDEC, which makes the HBM standard, has not yet formally standardized HBM3. But just like other makers of memory, SK Hynix has been working on next-generation HBM for quite some time.
