Almost all electronic devices you use, including personal computers, laptops, gaming consoles, and even servers that power the web and the largest social media companies, use DRAM ( Dynamic random access memory) technology to help processors function. So why do we still have DDR3 vs DDR4 debate?
We tried to bring across the following in this article :
DDR4 (double data rate fourth generation), as the name indicates, is a revolutionary step forward in-memory technology, offering better power efficiency and faster data speed compared to its predecessor DDR3 memory.
Compared to DDR4, DDR3 memory may not look that different.
Both of them offer similar form factors; however, some key differences set them apart, making the former the ideal choice for new-gen computers.
Read this article before you consider upgrading to a new memory module to resolve high RAM usage woes in Windows 10.
In this article, we take a look at all the DDR RAM types, compare DDR3 vs DDR4, and then see why DDR4 is the best of all DDR yet. So, let’s get started.
Double data rate third generation (DDR3) is a memory standard designed as a successor to DDR2, offering better speed, reliability, and power efficiency.
It uses 240 DIMM Pins, while DDR4 memory uses 288 DIMM Pins.
DDR3 offers a clock speed of 800-2133Mhz, where 2133 MHz is the peak it can offer with the usual clock speed varying between 1660-1800MHz.

Double data rate version 4 (DDR4) is the successor to the DDR3 memory. In DDR3, auto-refresh and self-refresh are performed to refresh content.
However, in DDR4, only self-refresh is performed, resulting in lower power consumption making it more efficient than DDR3.
DDR4 memory is also relatively faster than DDR3, with its minimum clock speed starting at 2133MHz and has no defined maximum clock speed. The DRR4 key notch is in a different place for easier identification.
As a result, you can put a DDR3 in a DDR4 slot, and a motherboard with a DDR4 slot cannot use DDR3 memory.

DDR
Introduced in 2000 as an alternative to SDRAM, DDR, based on SDRAM, was twice as fast as the data transfers that occurred on both edges of the clock signal.
DDR could also operate at a lower clock rate using less energy without compromising on the speed. DDR used 184 DIMM pins.
Pros:
Cons:
DDR2
Fast forward to 2003, as the technology progressed, computing devices needed something more efficient than DDR; hence DDR2 was introduced.
With an internal clock running at half the speed of the data bus, it was 2x faster than its predecessor while being more power-efficient.
The DIMM Pins count also saw an increase to 240 Pin from 184.
Pros:
Cons:
DDR3
2007 was the year that saw the launch of DDR3. With its internal clock cut in half again, it offered twice the speed of DDR2 at 2133MT/s with better power consumption numbers.
Apart from the speed, the bandwidth on each successive memory module also saw exponential growth from 1GB in DDR to 16GB in DDR4.
The So-DIMM Pins count was increased to 204 as well.
Pros:
Cons:
DDR4
Then came the most widely in use DRR type, DDR4, released in 2014.
Following the footsteps of its predecessors, DDR4 offered increased bandwidth capacity, improved power consumption number, and increased the data transfer rate up to 3200 MT/s with a voltage of 1.2 volts.
Needless to say, the newer technology was also relatively expensive than DDR3.
Pros:
Cons:
DDR3 | DDR4 |
Less expensive than DDR4 | Expensive higher than DDR4 |
Auto-refresh and self-refresh are performed to refresh content | Only self-refresh is performed to refresh content |
Less power efficient at 1.5v | Power efficient at 1.2v |
Supports maximum of 16GB memory | Has no defined maximum limit |
Slower clock speed at 800 to 2133 MHz | Minimum clock speed is 2133 MHz and has no defined maximum limit |
Lower latency than DDR4 | Slightly high latency than DDR3 |
To summarize, DDR4 being the latest standard is the fastest, more reliable, power-efficient and capable DDR available today. If you are looking to build a new PC or upgrading your laptop, DDR4 is the memory to consider.
However, make sure to check the RAM type in Windows 10 to know the DDR type supported by your computer. Next, go and find the best DDR4 RAM and DDR3 RAM for your desktop computer, depending on the compatibility.
