The Difference Between DDR3 and DDR4 RAM

You may have already heard about DDR3 & DDR4 RAM. And now if you are looking for the best RAM capacity for your PC. Then we are going to clear all your doubts and confusion related to DDR3 & DDR4 RAM.

What is RAM?

RAM (Random Access Memory) is one of the most mysterious and fundamental components of any computer and mobile memory. Random Access is the ability to store data that can be read or written in any order. The data which is stored in RAM is of volatile type and has the power to maintain any stored information.

The short-term memory of a computer is termed as RAM. It is the working space and capacity of your computer as all the programs and files do not start working without RAM. Moreover, this memory is more vital than the hard disk as it runs all the Web browsers and applications of your computer. In conclusion, It is a super-fast temporary data storage space that is needed for all computing resources.

Random Access Memory of computer have multiplexing & demultiplexing circuits, that guide the computer about data storage to be read or write. RAM devices have many data lines reaching from 8-bits to 16-bits.

We have enlisted the main types of this random memory below:

  • SRAM that is an abbreviation of Static Random Access Memory
  • DRAM that is an abbreviation of Dynamic Random Access Memory

What is DDR3 RAM?

DDR3 (Double Data Rate 3) is a type of SDRAM (Synchronous Dynamic Random Access Memory). To know about DDR3 you must know DRAM, which stores data in the form of tiny cells of capacitor or transistors in the form of a bit.

DDR3 RAM has a high bandwidth with a high-speed successor. It comes in the market as a successor of DDR2 RAM. It can transfer data at double rates which is eight times greater than its internal memory.

Samsung introduced the first DDR3 prototype RAM in 2005. Since then it has been playing a vital role in the standardization of DDR3. It was officially launched in 2007 by an independent semiconductor trade organization JEDEC.

What is DDR4 RAM?

DDR4 (Double Data Rate 4) is also a type of SDRAM (Synchronous Dynamic Data Access Memory). It is the latest fourth-generation variant memory. DDR4 arose with high bandwidth and greater efficiency.

To compete with the demands of World DDR4 was introduced with increased performance and decreased voltage. DDR4 has a higher clock speed rate with more powerful processors. The latest generation of RAM with advanced methodology has set its debut on smartphones and other devices.

Samsung introduced the DDR4 in 2011 and then this technology officially comes into the marketplace in 2014. As this RAM has more technical improvements as compared to DDR3. It brings advancements in the internal storage of the computer.

DDR3 VS DDR4

This question arises in everyone’s mind that what is the main technical difference between DDR3 vs DDR4 RAM. There is plenty of differences between these two short-term memories. But it depends upon your computer’s motherboard that which RAM is best for you. By digging up the difference you may know that a DDR4 computer can use DDR3, but those having DDR3 cannot slot to DDR4.

The following are the major differences between these two RAMs. These factors are related to voltage level, advanced clocking speed, and greater memory capacity.

Technical Advancement of DDR4 RAM

The main difference is that DDR4 RAM is equipped with nodules of 288 pin. While DDR3 operates on 240 pin nodules.

The DDR4 developed with more advanced and fascinating technology and cannot fit into an older computer. Moreover, Users can notice these advancements as it increases the battery timing of devices. Also, the DDR4 RAM has its two predecessors behind which are not many advances in computing functions as DDR4.

High clocking Speed:

The more fascinating feature of this RAM is high Clocking Speed. Higher the clocking speed higher the transfer rate of files. This RAM can easily transfer data at 2133 MT/s to 4266 MT/s. While the DDR3 technology can only support data transfer up to 800-2133 MT/s.

We can measure the Clocking Speed in MHz. And this clocking speed indicates the data transfer rate to CPU. As these two RAMs come with different speeds, capacity, and technologies the clocking speed is also different. The maximum clocking speed according to a recent survey is 2133-4800 MHz for DDR4 RAM which is greater than DDR3 RAM. As DDR3 RAM clocking speed is up to 2133 MHz only.

Level Of Voltage:

The voltage level of these two RAMs DDR3 vs DDR4 also differs, as the Two RAMs come in the marketplace with quite high differences. This new RAM uses less voltage as compared to DDR3 which uses 1.65 volts. High voltage consumption leads to high battery use.

DDR3

1.65V

DDR4

1.20V

While the DDR4 uses only 1.2 volts, the low voltage reduces the power consumption of battery and increases the battery life. The low voltages are also fundamental for the efficient running of the computer. The RAM using less voltage is more stable to work efficiently. The rough difference between the voltage use of the two RAMs is 15 watts and it seems to use high power.

Memory Capacity:

Memory capacity is more fundamental for better performance. The memory capacity directly links to the amount of data stored temporarily. To deal with multitasking or gaming your first choice is DDR4 RAM.

DDR3

512MB to 8GB

DDR4

2GB to 16GB

 

The DDR3 is designed to compete with a memory capacity of 512 MB to 8 GB. While the fourth-generation DDR4 has no limits to memory capacity. It can store data up to 16 GB.

Latency:

DDR3 VS DDR4 has different latencies. DDR3 has less while DDR4 has high latency. If we increase the memory timing of RAM then it will function with more efficiency. We can express memory timing in several parameters like CL, RCD, RAS, and RP and latency can be measured in Nanoseconds.

Conclusion:

If you are looking for efficient RAM with high bandwidth then we will definitely recommend DDR4. Go through our above-described article to learn about DDR3 vs DDR4 and to clear all the confusion. Keep your computers running for a long-time with more ease and use the DDR4 RAM. Now there is no difficulty to decide the best RAM, as the above guide depicts all the major differences between DDR3 vs DDR4.
