JEDEC today published their long-awaited JESD79-5 DDR5 SDRAM standard.
The DDR5 standard is expected to see the first DIMMs launching at a speed of 4.8Gbps, the Vdd is down to 1.1V (compared to 1.2V with DDR4), support for on-die ECC and other new features like decision feedback equalization, usage of MIPI I3C as the system management bus, and other improvements over DDR4.

DDR5 is rumored to be used by next year's Intel Sapphire Rapids server platform while on the AMD side is not expected until Zen 4.
