Compare DDR5 RAM with DDR4, DDR3, DDR2

RAM is the temporary memory available in the computer to store data and machine language used by the system. In this article, let compare and find the difference between DDR5 and DDR4 RAM, DDR3, and DDR2!

RAM good Random Access Memory (clipboard) is a term that most of us have heard about since we first got to know computers. If you’ve ever bought a computer, you’ve probably seen the term in its list of specs. And if you learn about computers, you probably already have some knowledge about different types of RAM.

RAM is the temporary memory available in the computer to store data and machine language used by the system. Hard drives can store data, even large amounts of information, so what do you need RAM for?

The reason is because the files that a program needs during work can be stored somewhere in the device memory. The time it takes the system to read and remember will depend on its location in memory. If the file is saved on the hard drive, you will have to wait until you choose the correct location to save the file, which still creates a certain delay in the reading process.

Once the file has been retrieved from the hard drive, it is saved to RAM. When you need to use this file for a certain purpose and have to re-open it over and over again, it will be taken directly from RAM to reduce latency.

When a program is run for the first time, all the information needed to run efficiently is stored in RAM, and the data is deleted when you turn off the computer.

DDR SDRAM or Double-data-rate SDRAM (dual data rate RAM) has a higher data transfer rate between the CPU and memory, thanks to tighter control of the clock signal.

The RAM slots on the motherboard are usually designed for a specific type of RAM. That’s why the pin configuration of DDR3 RAM is different from DDR2 or DDR4. This is also why you need to buy the right type of RAM compatible with your computer.

Over the years, there have been various versions of DDR SDRAM appearing on the market with major differences and improvements. As follows:

1. DDR (2000)

– Bus Clock (MHz): 100-200
– Voltage (volts): 2.5-2.6
– Data transmission speed (MT / s): 200-400
– Prefetch (min burst): 2n

2. DDR2 (2003)

4 other points of ddr3 and ddr4 ram
– Bus Clock (MHz): 200-533.33
– Voltage (volts): 1.8
– Data transmission speed (MT / s): 400-1066.67
– Prefetch (min burst): 4n

3. DDR3 (2007)

– Bus Clock (MHz): 400-1066.67
– Voltage (volts): 1.35-1.5
– Data transmission speed (MT / s): 800-2133.33
– Prefetch (min burst): 8n

4. DDR4 (2014)

– Bus Clock (MHz): 1066.67-2133.33
– Voltage (volts): 1.05-1.2
– Data transmission speed (MT / s): 2133.33-4266.67
– Prefetch (min burst): 8n

5. DDR5

In 2015, Intel held a seminar, revealing JEDEC’s plans for the release of DDR5 RAM by 2020. The JEDEC Technology Consolidation Association is a completely independent organization with a number of members who are big players in the global computer field.

DDR5 is expected to consume less power and double the memory bandwidth. There are also many rumors about the price of this 5th generation RAM. It is forecast to hold about 25% of memory market sales by the time of launch – 2020.
Above, gave you all the information you need about generation of DDR5, DDR4, DDR3, and DDR2 RAM. Choosing to buy any type of RAM depends on many different factors such as computer configuration, price you can afford, job requirements, …..
