What is the difference .. the most prominent differences between DDR4 and DDR5 RAM


The RAM, whether in the computer or mobile, is one of the very important components, as these memories are used to store files that the device needs to download very quickly, and with the spread of DDR4 RAM, a new type of RAM appeared, which is DDR5, and below we present the most prominent differences and assumptions between them as follows:

– the speed:

There is a difference in bandwidth or “speed”, which means Bandwidth, as the currently popular DDR4s offer a bandwidth of up to 3.2 gigabits per second, for each of their Pins, while DDR5 will come with almost twice that number, which is 6.4 gigabits per second. a second.

The new DDR5 RAM technology will also provide double frequency, as DDR4 memory provides a first frequency in the range of 1600 to 3200 MHz, and some of the leading RAMs offer between 4000 and 5000 MHz, while DDR5 memory will provide numbers up to 8400 MHz, which ranges between 3200 and 6400 MHz as the initial frequencies, but it will reach the huge 8400 MHz figure in the more expensive and more powerful models.

– Energy consumption

In the DDR4 RAM, the power management process was done by the motherboard itself, but in DDR5 memories the process will be done through a separate chip called PMIC (Power Management Integrated Circuit), meaning that the random memory will be smarter and you will receive Only the energy you need, nothing more, nothing less, and this will ultimately lead to energy consumption that adapts to the type of your use, not constant energy consumption.

RAM capacity

We note that the current DDR4 chipset has a maximum capacity, as it accepts up to 16 x 16 GB, meaning a total of 265 GB, and this equals 32 GB, but the situation for DDR5 will differ, as each chip will support up to 1024 GB , I.e. a total of 128 GB.
