DDR5 RAM: What You Need to Know

DDR5 RAM is the latest and greatest memory technology. It offers faster performance than DDR3 and DDR4 and is expected to become the standard for future computer memory. This article will explain what DDR5 RAM is, what it is used for, and some key benefits.

What is DDR5 RAM?

It’s the latest standard in-memory technology expected to be used in all high-end computers and laptops within the next few years. DDR stands for Double Data Rate, and the number 5 refers to the speed at which data is transferred between your computer’s processor and RAM (Random Access Memory). The fastest DDR5 RAM can reach up to 51.2 GB/s per module and two memory channels per module by reducing power consumption (by 1.1 volts) and offering a higher density than DDR4.

Release date of DDR5 RAM?

In September 2017, Rambus proclaimed that he was working on it, and it was finally released on November 15, 2018.

The Wait is Over: Here are the Benefits of DDR5 RAM

Memory Bandwidth

Memory Bandwidth DDR5 RAM is up to 4.8 Gbps and faster than DDR4. DDR5 memory bandwidth gives an initial transfer of 4.8Gbps per pin, while DDR4 delivers 3.2Gbps. Coming versions are hoped to double DDR4, reaching a maximum of 6.4 Gbps.

Transfer rate or frequency 

Transfer rate is the amount of data that can be moved per second. The number of bits that can be transferred in one second depends on the bit rate, a unit used to measure how fast data can be transmitted. The higher the bit rate, the faster the transfer speed. DDR5 RAM delivers up to 2 x DDR4 from 4800-6400MHz but may reach as high as 8400MHz, while DDR4 delivers up to 1866-3200 MHz.

Memory density 

RAM density is the memory capacity measured in gigabytes (GB) per square inch. The higher the density, the more benefits you get from using a RAM module. Another advantage of high-density memory is that it takes less space on your motherboard than standard memory modules.

DDR4 has the highest die density of any standard to date, with a maximum density of 16 Gbit per die. This translates to 256 Gbit or a total of 32 GB. DDR5, in contrast, leaves DDR4 in the dust with a maximum die density of 64 Gbit per die. Using DDR5 DIMMS, you can output a substantial data rate of four-time higher than DDR4, which is 64-bit per die translated to 1024 Gbit or 128 GB in total.

Burst Length

Burst Length DDR4 and DDR5 have different burst lengths. DDR4’s burst chop length and burst length is four and eight, respectively, while DDR5 has burst chop is eight and burst length is sixteen. A burst length of sixteen (BL16) permits a single burst to access 64 bytes of data, which is the typical cache line size. This is done with one or both of the two buffers devoted to the channel. This makes a lowering in purchasing costs and improvement in memory efficiency.

Power Management and Consumption

The difference between the two is not unlike that between a four and 8-cylinder engine. DDR5 has a lower power consumption than DDR4, with an approximate 10% reduction in power consumption only when running at full speed.

DDR5 saves power by using a lower voltage than DDR4, which consumes less power. DDR5 has a 1.1 V operation voltage compared to DDR4’s 1.2 V. The higher voltage of DDR5 consumes more power than the lower voltage of DDR4.

Why You Should Upgrade to DDR5

The demand for higher-performance DDR5 memory is increasing because of the evolution in graphics, storage, and processor speed. The increased need for faster access to data has led to the development latest technologies that operate with newer chipsets and processors that sustain higher frequency speeds. The need for more bandwidth has risen as processing power and memory capacity have increased. And, with the growth of particular applications, such as video editing and 3D rendering, you will want faster access to your data. The use of a faster memory also improves the overall PC performance


Finally, DDR5 RAM is faster and better than DDR4. It also has extensively higher bandwidth. It can handle more intensive operations and gaming without worrying about lag or slowdown. If you want to buy a new PC or upgrade your old one, ensure you get DDR5 RAM.
