DDR5 promises faster and more efficient computers

The Korean chipmaker (SK Hynix) has officially unveiled the world’s first units of DDR5 RAM that come with a capacity of 64 GB.

The South Korean company is expected to start selling it in the third quarter of 2021. The announcement marks a major step away from the DDR4 RAM modules that have dominated PC memory since 2013.

The announcement by the Korean chip maker (SK Hynix) comes after three years of promising to double the speed of computer RAM via DDR5.

DDR5-4800 chips support speeds between 4800 and 5600 Mbps, with potential data rates faster than DDR4, as well as lower energy use.

This speed means that the modules are 1.8 times faster than standard DDR4 modules, at a lower voltage of 1.1 volts instead of 1.2 volts.

SK Hynix claims this saving represents 20 percent energy savings, and the maximum speed allowed by the standard DDR5 specification is 6400 Mbps. The technology also allows for units of up to 256 GB.

JEDEC officially published DDR5 in July of this year, but SK Hynix unveiled its first chipset in 2018.

Aside from memory gains, DDR5 memory modules will have two 32-bit channels instead of one 64-bit channel, making it easier to increase peak bandwidth.

The modules themselves regulate voltage rather than the motherboard, allowing the DDR5 RAM manufacturer to control the frequencies that matter most.

SK Hynix has tested 6400 Mbps units, and within the Roadmap has units at 8400 Mbps. However, you will have to wait a while; Because the company targets data centers first, as these centers benefit most from capacity and additional efficiency.

It is estimated that DDR5 RAM will account for only 10 percent of sales by 2022, and reach 43 percent sometime in 2024.

It should then become the de facto standard for all computers, including game consoles.

Intel announced its support for the standard (DDR5) in future processors, but AMD has not formally adopted the standard, and it may not adopt it until 2022.
