Rambus already has the first chipsets to modules DIMM DDR5

As you know, JEDEC promises to finish the development of specifications DDR5 SDRAM and Gigabyte GA-P next year. The emergence of memory modules DDR5 that is a natural development of DDR4, sales is expected only in 2019. However, the company Rambus has already announced that is working in their laboratories with the industry’s first chipsets for the appropriate DIMMs. In Rambus expect the first to market the new memory in cooperation with the manufacturers of the modules.

The new memory will support data transmission speeds up to 6.4 Gbit/s, which allows double the bandwidth modules from the current 25.6 GB/s DDR4 provide, to 51.2 GB/s. In this case the supply voltage is reduced from 1.2 to 1.1 V. In contrast to the DDR4 that relies on getting the proper voltage from the motherboard, DDR5 modules will have its own voltage regulators.

Changes in the memory subsystem on the side of processors will enable an increase in the maximum number of channels embedded controllers from 12 to 16, allowing the connection of up to 128 GB of memory.

It is unclear how high the price threshold of transition to a new generation of DRAM to the end user. The current growth of prices on DRAM chips does not give reasons for optimism.
