In this article you will learn, what is the difference between DDR3 and DDR4 ram? DDR3 Ram was launched in 2007, till date had a good run, while DDR4 is the new 4th generation Random Access Memory. It’s faster than DDR3, can be used with up to 4th generation motherboards, and can also be used in Ryzen Motherboard.

What is DDR3?

DDR3 stands for ‘Double Data Rate 3 Random-Access Memory’. DDR3 Ram has 240 pins and consumes less power than DDR2. 

DDR3 clock speed ranges from 800 MHz to 2133 MHz. Popularly found clock speed varies between 1333 to 1800 MHz. In some cases, it can reach upto 2133 MHz.

History of DDR3

In early 2005, Samsung played a major role in the development of DDR3. In February 2005, Samsung introduced the first prototype memory chip of DDR3. 

In 2007 DDR3 Ram was launched officially but until the end of 2009, the sales were not expected to overtake DDR2 Ram.

In January 2009, DDR3 Ram sales were 29% of the total DRAM units. But the sale was rising to 72% by 2011.

Power consumption of DDR3 RAM

The power consumption of SDRAM chips varies based on many factors. Dell’s Power Advisor calculates that 4 GB ECC Ram DDR1333 RDIMMs use about 4 W each. 8 GB single module DDR3/1600 DIMM, consume 2.58 W, despite being significantly faster.

Higher module density

DDR3 RAM DIMM densities range from 1 GB to 16 GB. 

What is DDR4?

DDR4 stands for ‘Double Data Rate 4th generation Random-Access Memory’. DDR4 Ram has 288 pins, when compared with DDR3’s 240 pins, it consumes less power.

DDR4 Ram offers faster speed and responsiveness than all other generations of memory. DDR4 clock speed ranges from 2400 MHz to 4400 MHz 

DDR4 Ram is for gamers, professional designers, and enthusiasts who need to maximize their data rates.

Gaming modules have unique designs, heat spreaders, lower latencies, and faster speeds.

History of DDR4 RAM

In January 2011, Samsung announced and released the successful testing of a 2 GB DDR4 DRAM module based on a process between 30 and 39nm. Its maximum data transfer rate was 2133 MT/s at 1.2 V. 

In April 2011, Hynix started the production of 2 GB DDR4 modules at 2400 MT/s, it was also running at 1.2 V on a process between 30 and 39 nm.

Finally, in April 2016, Samsung announced that they started mass-production of DDR4 DRAM on a “10 nm-class” process.

Power consumption of DDR4 RAM

You should know about the DDR4 Ram power consumption before buying. DDR4 modules are energy-efficient and operate only on 1.2V, while DDR3 Ram operates on 1.5V or 1.35V. 

The low power consumption of DDR4 can give you substantial power savings. DDR4 allows operation at higher speeds on lower power, without cooling requirements.

Higher module density

DDR4 RAM DIMM densities range from 2 GB to 128 GB. 

How does DDR4 Ram differ from other DDR Ram generations?

The following table compares the different DDR4 Ram generations.

Let’s see that the difference between DDR3 and DDR4 Ram:

1.DDR3 stands for Double Data Rate Generation 3.DDR4 stands for Double Data Rate Generation 4.
2.DDR3 Costs less than DDR4.DDR4 Ram costs higher than DDR3.
3.In DDR3, auto-refresh and self-refresh are performed to refresh its content.While in DDR4, only self-refresh is performed to refresh its content.
4.DDR3 consumes more power than DDR4.DDR4 consumes less power than DDR3.
5.The speed of DDR3 is slightly slow in comparison to DDR4.DDR4 speed is faster than DDR3.
6.DDR3 has a maximum capacity of 16 GB memory.DDR4 has no maximum capacity limit or capability.
7.The clock speed of DDR3 from 800 MHz to 2133 MHz.While the minimum clock speed of DDR4 is 2133 MHz and it has no defined maximum clock speed.
8.DDR3 has lower latency than DDR4.While DDR4 has more latency than DDR3.
9.DDR3 was used earlier in computer systems.While DDR4 is used now-a-days in latest computer systems.

What are the advantages of DDR4 Ram over DDR3 Ram?


DDR4 modules are more energy-efficient than DDR3 Ram. DDR4 operates only at 1.2V, compared with DDR3’s 1.5V or 1.35V. The less power consumption gives you substantial power savings and allows operations at higher speeds, without cooling requirements.

Data transfer speed 

ATP’s latest DDR4 modules for embedded and industrial applications deliver high-speed data transfers up to 3200 MT/s. DDR4-3200, the latest industrial DDR4 offering from ATP, transfers data about 70% faster than DDR3-1866, one of the fastest DDR3 versions available, for a big boost in theoretical peak performance.
