DDR5 is planned to reduce power consumption once again, while doubling bandwidth and capacity relative to DDR4 SDRAM.[1] A 2016 presentation by Intel suggested a JEDEC plan to release a 2016 DDR5 SDRAM specification, with the memory being available for end user purchase in 2020.[2] In March 2017, JEDEC announced its plan for the DDR5 specification release in 2018.[3] JEDEC's Server Forum 2017[4][5] claimed a date to offer a DDR5 SDRAM preview on June 19, 2017 accompanied by a DDR5 SDRAM Workshop on October 31 – November 1, 2017.[6] Rambus announced a working DDR5 RAM in September 2017, with availability not expected until Q3 2018.[7] On November 15 2018, SK Hynix announced completion of its first DDR5 RAM chip. It runs at 5200 MT/s at 1.1 Volts.[8] In February 2019, SK Hynix announced a 6400 MT/s chip.
