Recommended Reading: DDR5 vs DDR4: Does it Matter?

This is an excerpt from a recent educational article by Global American:

When shopping for PC memory, we consider the capacity of the RAM, but does the version also matter? What’s the difference between DDR5 and DDR4? Let’s take a look. As a rule of thumb, new versions of any sort of hardware interface double the speed and bandwidth. This holds not just for RAM, but even for technologies like USB, SATA, WiFi, etc.

The DDR5 follows this trend as well, offering twice the bandwidth, effectively doubling the rate of data transfer. In terms of numbers, this means potentially going up to 51 GB/s from the earlier 26 Gb/s.

And not just transfer rate; the clock speed, which decides access rates and can bottleneck the processor, is doubled by DDR5 as well. DDR4 is capable of a maximum frequency of 3200 Mhz, which has been bumped up to a whopping 6400 Mhz with DDR5.
