On a new post on its website, SK hynix says that with the recent dramatic increase in AI demand and data processing, the needs for high bandwidth memory (HBM) for faster system speed are "surging". Not only that, but securing memory power efficiency has emerged as a key requirement as power consumption for data center operations has increased. SK hynix has far exceeded the JEDEC standard operating speed of 8Gbps for HBM4, pushing up into 10Gbps operating speeds for its HBM4 memory. HBM4 has the industry's best data processing speed and power efficiency, doubling the bandwidth through the adoption of 2048 I/O terminals over the previous-gen HBM3 standard, and power efficiency has climbed by over 40%. SK hynix expects AI service performance improvements by up to 69% when HBM4 is used, which will "lead to solving data bottlenecks and significantly reduce data center power costs".
