DDR3 vs DDR4

DDR3 vs DDR4: Must Know Differences

What exactly is this RAM?
The memory of a computer that can be read and altered at any time is called random access memory (RAM). When the power supply to the personal computer or laptop is turned off, any information that was stored in this kind of Memory will be deleted. It is possible to refer to this component of the computer system as the main Memory, the temporary Memory, the cache Memory, or the volatile Memory. Random Access Memory is the complete abbreviation for RAM.

What is DDR3?

System memory typically makes use of DDR3, which is an important variant of the third generation of SDRAM. This particular kind of random access memory (RAM) is able to move data from one location to another at a more rapid rate. RAM with a double data rate is referred to as DDR3, which is its full acronym.

What is DDR4?

DDR4 RAM is the most recent iteration of RAM, and it will play a significant role in the computing of the next generation. As a result of DDR4’s reduced voltage and increased transfer rates, it is now possible to achieve both the highest possible efficiency and the fastest possible speed. Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory is what the acronym DDR4 SDRAM stands for in its entirety.
Characteristics of the DDR3
The following is a list of the key characteristics of DDR3 SDRAM:

Features of DDR3

Data transfer rate: 800 to 1600 MT/s (mega transfers per Second)
Operating voltage: 1.8 V
Reduced minimum threshold for signalling x8 prefetch with power reduction
The utilisation of dynamic ODT for enhanced write signalling
Quick-and-dirty architecture
Read/Write Levelling
Driver calibration
Resetting the device
addressing mirroring on DIMMs
Enhanced pinout of the device

Features of DDR 4

The following is a list of important characteristics of the DDR4 SDRAM type:

Reduced minimum signalling requirements
8 times the power reduction Prefetch Dynamic ODT for the purpose of enhancing write signalling
Quick-and-dirty architecture
Adjustment for Reading and Writing
Device for the calibration of drivers Reset DIMM address mirroring
Enhanced pinout of the device
Data transfer rate 2133 to 3200 MT/s


Here are the difference between DDR3 and DDR4 RAM:

DDR3 RAM stands for Double Data Rate version 3. DDR4 RAM stands for Double Data Rate version 4.
DDR3 RAM was introduced in 2007. DDR4 was reading released in 2014.
The cost of DDR3 is lesser than DDR4. DDR4 cost is higher or more than DDR3.
DDR3 consumes less power than DDR2 but more than DDR4. DDR4 consumes less power than DDR3.
The speed of DDR3 is slow in comparison to DDR4. DDR4 speed is faster than DDR3.
DDR3 maximum memory size is 16 GB. DDR4 has no maximum limit or capability.
The clock speed of DDR3 varies from 400 MHz to 1066 MHz. The clock speed of DDR4 varied from 1066 to 2133 MHz.
DDR3 has lower latency than DDR4. DDR4 has more latency than DDR3.
DDR3 has lower latency DDR4 has more latency than DDR3
Auto-refresh and self-refresh are performed for content. Only self-refresh is performed for a content.
DDR3 RAM includes ECC memory, which compresses extra data byte lanes. DDR4 RAM offers computing capabilities on different platforms like smartphones, tablets, PC, laptops, etc.
DDR3 RAM works on 1.50 V voltage DDR3 RAM works on 1.20 V voltage.
DDR3 RAM has a 240-pin interface. DDR4 RAM has a 288-pin interface.
This type of DDR RAM is backward compatible with the older RAM generations. This type of DDR RAM is not backward compatible with the older generation’s RAM.
Decade-old demand for DDR3 RAM is waning. The demand for DDR4 RAM is on a constant rise because of its implementation of emerging technologies.


Advantages of DDR3

The use of DDR3 has the following advantages and advantages.

DDR3 is capable of transferring data at a faster rate, reaching up to 6400 MBps.
The bandwidth or peak data rates can be increased as a result.
DDR3 uses less power consumption.
When compared with DDR2, DDR3 has lower levels of latency.
DDR4’s Many Positive Aspects

Advantages of DDR4

DDR4 not only has a higher module density, but it also has a very low power consumption rate.
The use of DDR4 is recommended for high-speed gaming.
DDR4 is capable of more DIMMs than previous generations.
When compared to its earlier iterations, the data transfer rate now operates at a significantly faster speed.
DDR4 memory can transfer data at higher speeds while operating at very low voltage and does not require any cooling.
DDR4 has significantly lower latency than any of the previous DDR versions.
Because DDR4 only relies on self-refresh to update its content, it also has a lower power consumption.
