DDR5 is designed to meet increasing needs for efficient performance in a wide
range of applications including cloud computing, and data center processing.
The DDR5 memory provides developers with twice the performance (4800 to
6400 MT/s) and improved power efficiency in comparison to DDR4 by using
an on-DIMM 12V voltage regulator (PMIC) and 1.1 I/O Voltage.
DDR5 also improves scaling performance without degrading channel
efficiency at higher speeds. This increased performance is achieved
by doubling the burst length to BL16 and bank-count from 16 to 32. For
increased reliability and efficiency, a DDR5 DIMM utilizes two 40-bit fully
independent sub-channels on the same module. DDR5 memory modules
have a maximum die density of 64Gb and hence are capable of
having a much higher DIMM storage capacity.
