Many gamers and enthusiast designers swiftly switched from DDR4 to DDR5 ram technology.

It is because DDR5 grants more power, efficient optimization, and increases productivity at a glance.

In gaming, DDR5 has performed outstandingly. With ddr5 ram in place, gamers can get higher frame rates for games like Assassin’s Creed Mirage, Cyberpunk 2077, and Watch Dogs: Legion games at an average of 170 in 1080p, 150 in 1440p, and 120 in 4K.

Read everything about DDR5 technology in this blog.


What Is DDR5 Technology?

DDR5 is the fifth generation of Double Data Rate Synchronous Dynamic Random Access Memory also known as SD-DDR5 that incubates dual 32-bit subchannels to increase efficiency and lower the latencies of data accesses for the memory controller.

Being said that, DDR5 is designed with new features to submerge the limitations of DDR4 technology. The next-gen DDR5 RAM debuts at 4800 MT/s and consumes ~20% less power than DDR4 equivalent components at 1.2V.

In addition to the DDR5 technology, enhancement has been made in PMIC, SPD hub, bandwidth, latency, and On-die ECC.

Let’s read some of the innovative technology behind the DDR4 vs DDR5 development.

Bandwidth

In association with the Joint Electron Device Engineering Council, DDR5 technology offers multiplied bandwidth compared to DDR4 RAMs.

DDR4 modules have data rates ranging from 1600 — 3200 MT/s. The DDR5 modules have data rates ranging from 3200 – 6400 MT/s but you often see 3200 MT/s DDR5 in the market.

The DDR5 4800 MT/s from Kingston and Crucial RAMs are common in the market.

Power Architecture

We have noticed some significant change in power architecture as well. The new DDR5 uses less power than DDR4 (1.1 volts vs. 1.2 volts).

Additionally, there is change in onboard PMIC or Power Management Integrated Circuit, concluding 12V PMIC on server-grade DRAM DIMMs and 5V PMIC on consumer-grade DRAM DIMMs.

This new enhancement is brought to improve power management efficiency and help motherboard manufacturers not to worry about power management.

On-Die ECC

Many of you don’t know about on-die ECC, it stands for Error Correcting Code which is responsible for preventing data loss or corruption.

In DDR4 vs DDR5 technology, this feature was seen as optional. But all DDR5 RAM onboard with ECC features is pivotal.

Burst Length

DDR5 comes with significant changes in burst length characteristics. Basically, burst length helps DDR read and write effectively.

The DDR5 burst length observed was double i.e. eight and sixteen, respectively compared to DDR4, incorporating burst length in four and eight, respectively.

This change optimally allows a single burst to access up to 64 Bytes of data which boast read and write efficiency at increased rate, resulting in high performance.

Bit Channel

The DDR5 RAMs possess new bit channel alignment representing two independent 32-bit channels, offering impeccable loads of performance for your tasks such editing, rendering, and sharing.

Basically, the single stick of DDR5 ram is already configured and optimized to run dual-channel mode. This new feature eliminates adding more slots of RAM to get more feasible results, like it happens with DDR4 RAM.

Thank god… it’s gone now! Right?

Capacity

DDR4 vs DDR5: Another great feature in DDR5 is that it has a maximum memory capacity of 512 memory. Meaning, the limit of expanding memory up to 64GB is gone. With DDR5 in use, gamers can boast memory size up to 512GB.

This innovation converges chip manufacturers to take advantage of the total bandwidth and capacity of the DDR5 standard.

Compatibility

There is a saying ‘new innovation calls new things’ and it is exactly what happened with the launch of DDR5 technology in the market.

For a new memory standard, new hardware is required. With DDR5 modules, you may require a new motherboard.

For example, AMD switched to DDR5 with their Ryzen 7000 series processors. While the Intel 12th and 13th gen chips support DDR4 and DDR5 memory.

You are in luck if you have a motherboard above AMD’s 5000 series CPUs and Intel’s 11th-gen Core processors.

Benefits Of Next-Gen DDR5 Memory

The new innovation in DDR fifth generation memory offers a myriad of benefits to the users including office professionals, studio artists, and gamers alike.

Greater speed performance

The sleek optimization in dual-channel memory and discrete power architecture concept in DDR5 help deliver greater starting speed performance in reading, writing, and sharing tasks.

The increased frequency in DDR5 memory that ranges from 3200MT/s to 6400MT/s also helps boost speed and performance overall.

Reduced power consumption

Users get reduced power consumption with DDR5 memory as 1.1V, DDR5 consumes ~20% less power than DDR4.

This little drop in energy consumption from 1.2V to 1.1V may help conserve battery life for laptops. It also advantages enterprises with servers working around the clock.

Additional temperature sensors

Another benefit of DDR5 RAM technology is that it has temperature sensors to the end of the modules that considerably monitor thermal conditions across the length of the DIMM.

In the context of ddr4 vs ddr5, this feature intelligently shall help users to know the stats of their memory temperature with details on screen.
