DDR3 vs DDR4 - The difference between DDR3 and DDR4 RAM

DDR3 has reached the end of the long run, and DDR4 is the future. So here we will discuss is DDR4 really batter than DDR3 RAM.

While DDR3 has better running, DDR4 is the new memory of choice.

DDR means Double Data Rate

Both DDR3 and DDR4 are the versions of Double Data Rate (DDR).


You probably have questions like what are the differences between DDR3 and DDR4 RAM? Is DDR4 worth it over DDR3?. We will discuss everything but before going to that first let's know about what is DDR3 and What is DDR4 RAM?

What is DDR3 RAM?

DDR3 was first released in 2007. The double data rate three, DDR3 is a DRAM (Dynamic Random-Access Memory) released as a successor of DDR2.

DDR3 chips have bus clock speeds of up to 10 MHz, 1 to 24 GB, and consume 30% less power than their predecessors.

The DDR3 RAMstick has 240 pins for desktop computers. For laptop computers, the DDR3 RAM Stick has 204 pins.

What is DDR4 RAM?

Released in the market in 2014, DDR4 SDRAM is an abbreviation of "Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory", the latest version of memory in computing.

DDR4 can achieve high speed and efficiency, leading to a decrease in transfer rates and voltages.

DDR3 vs DDR4 Physical Difference

DDR3 vs DDR4 Physical Difference

The main physical difference between DDR3 and DDR4 is that DDR3 uses 288 pins compared to 240 pins in DDR3 and the key is in a different location. Also, the pins in the DDR4 are not actually in a straight line but are slightly curved from the middle adhesive in the end compared to the pins.

The bare DDR4 RAM module has a height of 31.25mm, compared to the DDR3's 30.35mm.

In practice, the low-to-millimeter difference in altitude is absolutely nothing because almost all high-performance memory modules released in the last decade have a heat sink.

DDR3 vs DDR4 Benchmark

DDR4 RAM improves almost all aspects of DDR3 RAM. It has a very high transfer rate, operates at low voltages, is more stable, and brings modest but measurable performance benefits when working with memory-intensive applications.

For any market segment, DDR4 has a higher data rate and a worse time than DDR3. This gives the DDR3 module more than the latency gain at 4.58ns, while the DDR4 at 5.625ns.

DDR3 vs DDR4 Compatibility

Are DDR3 and DDR4 Laptop Memory (RAM) Compatible? This is the most commonly asked question when it comes to memory updates.

For example, you bought a new laptop with DDR4 RAM, and you want to add more memory to your DDR3 RAM module from your old laptop.

You wonder if that is possible. Unfortunately, this cannot be done. DDR3 and DDR4 laptop memory are not compatible / cannot be changed.

Is DDR4 compatible with DDR3 laptop? First, the DDR3 laptop RAM module does not physically fit into the DDR4 laptop RAM slot, and vice versa.

Conditions on connectors of memory sticks are in different places. The same applies to bumps in the RAM slot on the notebook's motherboard. Also, the number of pins does not match.

The DDR3 laptop memory module has 204 pins, while the DDR4 has 260. Finally, the DDR3 memory is slightly smaller than the DDR4 - 2.66 vs. 2.74 inches.

Therefore, the DDR3 memory module does not fit into the DDR4 slot.

DDR3 vs DDR4 Price

DDR4 does cost a bit more than DDR3 (about $70 for 16GB DDR4-2666 compared to $60 for DDR3-1600).

DDR3 vs DDR4 Gamming

DDR3 vs DDR4 Gamming

The difference is minimal and not noticeable for gaming. You can't mix and match RAM with the motherboard, so you need to decide whether you want an old or new platform based on the money you want to spend, and how long you want the system to be at its full performance today.

Is DDR4 Worth it Over DDR3?

Not as usual. There is no difference in performance compared to the same speed of DDR4 and DDR3.

Certain functions benefit from a certain type of RAM, but overall it is a wash. Things are more complicated when comparing DDR3-1866 to DDR-2666.

But in the end, the query of DDR3 vs DDR4 comes down to the CPU and motherboard of your choice.

There are a few selected examples that support two memory types, but you end up with half as many slots (eg, two DDR3 and two DDR4, instead of four DDR4).
