WebFeb 1, 2024 · You can never have enough memory bandwidth, and DDR5 helps feed that insatiable need for speed. While DDR4 DIMMs top out at 3.2 gigatransfers per second (GT/s) at a clock rate of 1.6 gigahertz (GHz), initial DDR5 DIMMs deliver a 50% bandwidth increase to 4.8 GT/s. DDR5 memory will ultimately scale to a data rate of 8.4 GT/s. WebHMC2 offers a variety of SerDes rates ranging from 12.5 Gbit/s to 30 Gbit/s, yielding an aggregate link bandwidth of 480 GB/s (240 GB/s each direction), though promising only a total DRAM bandwidth of 320 GB/sec. A package may have either 2 or 4 links (down from the 4 or 8 in HMC1), and a quarter-width option is added using 4 lanes.
