DDR5 is already being made; expect it in 2019
It seems just yesterday that Intel dropped their X99 platform with support for DDR4 memory. Now, Rambus, a company who develops memory technologies, announced that they have a functional DDR5 DIMM.
Luc Seraphin, senior vice president and general manager of the Rambus Memory and Interfaces Division, said, “This is the very first silicon-proven memory buffer chip prototype capable of achieving the speeds required for the upcoming DDR5 standard. Data-intensive applications like Big Data analytics and machine learning will be key drivers for the adoption of DDR5, with enterprise close behind.”
“We are proud to provide an early path to adoption with the first working buffer chip prototype running at the anticipated performance of next-generation DDR5. This demonstrates our continued dedication to be first to market and remain on the leading edge of industry standards.”
“Server DIMM chipsets, like registered clock drivers and data buffers, will be critical to enabling higher memory capacities while maintaining peak performance,” Seraphin added. “Our server DIMM chip prototype leverages the signal integrity and low power, mixed-signal design expertise of Rambus to enable development of next-generation solutions for future data center workloads.”
The Joint Electronic Devices Engineering Council (JEDEC) hasn’t created an industry standard for DDR5 quite yet. They are, however, working on it. DDR5 is slotted to double data rates of DDR4, from 3.2 gigabits per second to 6.4 gigabits per second. This will result in 51.2 gigabytes per second up to 25.6 gigabytes per second.
The base speed is expected to be 4800MHz, something seems in other DDR4 sticks. However, it’ll probably be 2019 or later before these sticks show up in servers, with consumers seeing them shortly after.
