What does ddr5 memory mean?

ddr5 memory refers to a computer memory specification that focuses on improving the density and speed of DRAM storage. It supports a single 64Gbit DRAM memory chip, which is four times the maximum allowed capacity of DDR4 (16Gbit). The standard frequency of ddr5 is 4800mbps, and the peak frequency reaches 6400mbps, so the performance is powerful.

What does ddr5 memory mean?

DDR5 stands for DDR5 SDRAM. It is a high-bandwidth computer memory specification and a memory product belonging to the SDRAM family. DDR5 focuses on improving the density and speed of DRAM storage, supporting a single 64Gbit DRAM memory chip, which is four times the maximum allowed capacity of DDR4 (16Gbit).

DDR5 is a computer memory specification. Compared with DDR4 memory, the DDR5 standard has stronger performance and lower power consumption. Other changes include reducing the voltage from 1.2V to 1.1V, while increasing the bus efficiency to 32/40 bits per channel (ECC), and increasing the number of prefetched Bank Groups to improve performance. There is no platform that officially supports DDR5 memory. AMD is expected to change the socket on the Zen4 processor in 2021 to support DDR5 memory. However, Intel’s 14nm and 10nm processors have not made it clear that DDR5 memory support will be supported. The official roadmap shows that 2021 The 7nm process Sapphire Rapids processor will only be available in DDR5 in 2018, and it will be the first server product. It is estimated that consumer grade processors will have to wait for a while.

Most users today are using ddr3 or ddr4, and ddr5 is relatively new.

The standard frequency of ddr5 is 4800mbps, and the peak frequency reaches 6400mbps, so the performance is powerful.

ddr5 memory expansion introduction:

1. Compared with ddr4 memory, ddr5 has more powerful standard performance and lower power consumption.

2. The voltage has also been reduced from 1.2v to 1.1v, each channel is 32/40 bits, and the bus efficiency has also been improved.

3. The improved ddr5 function will increase the actual bandwidth by 36%, even at the speed of 3200MT/s and 4800MT/s.

4. Compared with ddr4-3200, the actual bandwidth will be 87% higher, which is also one of the very important performances.

Extended knowledge: The difference between ddr5 and ddr4

1. Bandwidth speed:

The bandwidth of ddr4 is 25.6GB/s,

ddr5’s bandwidth is 32GB/s.

2. Chip density:

DDR4 single chip density is: 4GB, and the maximum capacity of a single memory can reach 128GB.

DDR5 single chip density is: 16GB, which can achieve a higher capacity per chip.

3. Working frequency:

ddr4 minimum working frequency standard is: 160MHz, and the maximum working frequency is: 3200MHz.

The working frequency of ddr5 is as high as: above 4800MHz, and the highest frequency reaches: 6400MHz.

4. Power consumption:

The single power consumption of ddr4 memory is: 1.2V.

ddr5 memory power consumption has been reduced to: 1.1V.
