SK Hynix has unveiled its latest DDR5 memory roadmap in which it has confirmed to commence mass production of the next-generation DRAM chips this year. Back in November 2018, SK Hynix announced the development of the industry's first 1Ynm 16Gb DDR5 DRAM, built in accordance with the JEDEC standard and now they are giving us a glimpse of what's to come next.

According to SK Hynix, the DDR5 memory aims to offer more than two times the bandwidth when compared to DDR4 memory. It is stated that moving from DDR3 to DDR4 all the way back in 2013, was a 33% increase in bandwidth (1600 Mbps to 2133 Mbps). With DDR5, SK Hynix's goal was to achieve more than 50% increase in bandwidth per DIMM.
