New DDR5 standard doubles SDRAM performance
New RAM specifications will allow developers to double productivity and reduce hardware power consumption.
A recent document of the Association of the Semiconductor Industry provides for a four-fold increase in the maximum crystal density – up to 64 GB (according to the old standard 16 GB). In addition, each DIMM will be able to process two 32-bit memory channels instead of one 64-bit, which will increase the packet length and increase efficiency.

The maximum data transfer rate in DDR5 will rise to 6.4 Gbit / s, twice exceeding the DDR4 indicator, although the first modules will enter the market with a limit of 4.8 Gbit / s. Energy consumption should be reduced from 1.2 to 1.1 V, the real level of savings has yet to be determined in practice.
According to an Intel spokesperson, DDR5 shows a big leap in memory capabilities, providing for the first time a 50% increase in bandwidth with the advent of new technology that meets the requirements of artificial intelligence and high-performance computing.
The first slats with DDR5 specifications should enter the market in 2021.
However, while the AMS was agreeing on new specifications, scientists invented a more efficient and faster type of RAM cells that could work with the ternary number system.
