DDR3 vs DDR4 Ram: The Truth, Differences, Comparison(2019 Updated)


Every computer requires a memory which is most frequently accessed by the system to continuously restore all the media and information back to where it belonged the last time you sat on your computer. This is the function of the RAM in every computer system.The initial communication is held between the processor and the RAM, and the rate of transmission depends on the measurement of the speed of the RAM. The speed is generally measured in frequencies, and thus we shall learn more about the ta brief comparison of DDR3 vs DDR4 RAM and also the differences between them.

Tips and thoughts on the evolution of DDR RAM over the years.

The double data rate RAM or DDR RAM was introduced first in the early 2000s with the help of which data was able to transfer itself twice the normal speeding higher frequencies. The various chronological versions of the RAM namely, DDR2, DDR3, DDR4 variants provide the improvement of the speed of the RAM and also the reduction of the overall power consumption of the same.

This means that not all RAMs are compatible with everything. It is to be noted that while installing a RAM to your motherboard, be sure to match the RAM series compatible with the motherboard.

Top 5 Picks: DDR3 Ram Vs DDR4 Ram

Short answer: comparison between DDR3 and DDR4 RAM

First of all DDR3 RAM was introduced in late 2007. While it was an improved version of the DDR2 RAM, the introduction of the DDR4 RAM in the market did not have any improvement over the DDR3 RAM. However, it had some physical overview differences, a slight increase in the speed and frequencies and better voltage optimization. We shall dig in deeper on the topic later in the article.

DDR3 vs DDR4 RDDR3m: five rounds

According to the studies, the RAM was introduced in the early 2000s which revolutionized the modern computing system. All the temporary information was to be stored on these green chips which took a certain power to operate itself. With the connections made from the processors and the RAM itself, it could communicate with the whole computer.

DDR3 vs DDR4 is just the starting of the overall five rounds of in-depth comparison between the both.

Round one: know DDR3 and DDR4.

RAMS for a computer with higher frequencies always came up in the market. Recently, DDR4 has replaced the DDR3 RAM by providing even better clock speeds and better power consumption rate.


The RAM sticks are made by many manufacturers in the market, and all the RAM sticks are pretty much the same with respect to the features and the DDR3 RAMs they offer are of the same type but with the difference in the clock speed.


DDR4 RAMs have recently been replaced by the newer rams in the market, the DDR4 Rams stick. These memory sticks provide better latency and also better clock speeds which makes transactions and transmissions between file faster than expected.

The key difference between DDR3 and DDR4 RAM: let us study about it.

The evolution of the RAM from DDR3 variant to DDR4 one has brought in not much of any difference. Although some of the noticeable differences between both the dim sticks are:

  1. Physical looks: the newer versions of the DDR4 RAMs look better than the previous green memory sticks.
  2. Latency: the new DDR4 memory sticks provide better latency than the older DDR3 version.
  3. Speed: the speed of the DDR4 RAM has slightly increased than that of DDR3 RAM.
  4. Voltage consumption: the voltage intake by the DDR4 RAM is much less compared to what a DDR3 RAM took.
  5. Compatibility: these new RAMs are compatible with all the motherboards currently available in the market right now.

Brief summary

RAMS are an important aspect of the whole computing system. Each and every part of a CPU is codependent on each other. Suppose you have a computer fully loaded with the best components but lack the RAMs, your system will not boot up because it will not have the memory to withhold the boot information temporarily. Thus it is important to get the right kind of Ram for your system.

Round 2: DDR3 vs DDR4: what has changed in these years?

If compared in details DDR3 vs DDR4 Rams and the difference between DDR3 and DDR4 RAM sticks, nothing that great has changed other than certain tweaks in the algorithms of the sticks to make performance even better using the newer DDR4 RAMs on the computer.

Physical changes: how does it look?

Both the Rams are different from each other. This means that the DDR3 RAM previously sported the 240 pin connector nodule which slid into the motherboard Ram dim slots easily. The development teams have led to the invention of a newer model of the DDR3 Ram which was the DDR4 Ram. This RAM makes use of a 288 pin connecting nodule.

This is the key difference in the physical appearance of the two RAMS. Upon considering further in DDR3 vs DDR4, I found that the DDR4 rams had a better outer coating which helped to radiate the heat generated which lacked in the previous DDR3 RAM models.

The motherboards come with dim slots meant for the insertion of the RAM sticks into the slots. It is to be noted that while placing a RAM into the slot make sure that the RAM is facing the right direction else a mismatch of slot and RAM might lead to damaging the whole RAM stick.

Operating voltage: how much do they consume?

Every part of the computer consumes some amount of energy in order to run efficiently all throughout the time when the computer is switched on. DDR3 RAM used a total of 1.5V at native input levels however this could be tweaked and reduced to a 1.35V in order to make the RAM stick more power efficient.

DDR4 RAMs on the other hand natively operate on 1.2V and can be reduced further to 1.05V, which means that the overall input of the power is less which leads to less heat produced and also a faster transfer rate for the file between one place in the system to the other.

The reduced power input of the DDR4 RAMs is the comparison points between the DDR3 vs DDR4 RAM sticks. These sticks with a lower operating power input level tend to provide better stability and result in the total efficiency increase of the system itself.

Stability: which is more stable?

Comparison of the DDR3 vs DDR4 RAM sticks we found out that the previous models of the DDR3 Rams used more power and thus the efficiency of the computer systems using DDR3 RAMs was much less. On the other hand, DDR4 made use of less power and was smoothly operating with minimal power input levels.

The less the overall intake of the operating power from the external source, the more stable will the RAM be on a computer system. This is the sole reason why DDR4 RAMs, taking in 1.05V power, can be more stable on a system than a memory stick taking in 1.35V or higher.

Refresh algorithm: a deep analysis

Refresh algorithms in RAMs are the number of times a RAM refreshes its memory in case it stays idle for too long. The RAM is a temporary memory and is volatile in nature. This means that all the data written on the slots of the RAM memory can get erased any moment form the time of being written on the RAM.

DDR3 used two different types of refresh algorithms namely the AR or the automatic refresh and the SR or the self-refresh. The DDR3 Ram used the AR algorithm when the computer was in full operation and the SR algorithm while the computer is at idle or sleep mode. This made the system remember the last work done on the computer.

DDR4 Rams, on the other hand, make use of the automatic refresh algorithm. In DDR3 vs DDR4 comparison, DDR4 RAMs consume less power input which resulted in a stable operation. This provided and made way for automated refresh rates which kept on refreshing at low power wattages.

The refresh algorithm of the RAMs be it DDR3 or DDR4 RAM stick, all depends on the interior temperature of the CPU and also depends on the onboard temperature of the RAM sticks. Its seen that high temperature resulted in a lower refresh rate while a cooled CPU provided faster refreshing and overall soothing power consumption by the RAM itself. So it is hence proved thatDDR4 Rams are more efficient in respect of the refresh algorithms of the same.

Clock speed: which serves more speed?

The clock speed on the DDR3 Ram was tentatively very low. It started on from 800MHz and rose up to a maximum of 2133MHz due to the wide use of these RAMs worldwide. Developers boosted up the speed capacity of the RAM and made it to a minimum of 1333MHz.

Whereas, the newer DDR4 RAM has a native speed of 2133MHz and can go as high as 4266MHz. This increase in clock speed of the RAM allows faster transfer rate of the files and also increases the overall performance of the computer. Overclocking the speed limits on the DDR4 RAM shows the power of the same over DDR3 RAM.

Latency: which among the two is better?

On a comparing the difference between DDR3 and DDR4 RAMs we can find out that the newer version of the RAM, DDR4 has a higher latency than the previous DDR3 RAM. As a matter of fact, finding RAMs with lower latency is good, hence on this one, DDR3 has a slight edge over the newer DDR4 RAM on the basis of lower latency units. There are also DDR4 RAMs which provide lower latency; we just need to search for them.

Memory capacity: what has more of this?

The new DDR4 RAMs are manufactured to support memory up to 2GB per stick. This is known as module density. Module density effects the overall performance of the RAM stick as the chips used in the manufacturing process tend to have higher modular density thus, housing more RAM on every chip.

This is the reason why we can find a 16GB RAM in just one DDR4 stick which can rise up to 64GB meant for server units only. DDR4 is the technology which the future awaits for. Thus these are the certain advantages of the DDR4 RAM over the DDR3 RAM. Let us look further into the matter.

Brief summary

Most of the modern day computers are slowly moving towards the future. The motherboard RAM slots are getting replaced for the more compatible and easy to use DDR4 RAM sticks which will help in improving the overall performance of the computer. With all the benefits of the DDR4 RAMs mentioned above, this is surely going to be the next gen for the computing system of the world.

Round three: DDR3 vs DDR4 Benchmarks

Benchmarking is the process of comparing a product with the others on the various aspects required to be tested on and then scoring the products based on the results they give.

Which is better? DDR3 or DDR4?

For this result, I have had taken a HyperX fury DDR3 1866MHz C10 memory stick which had a capacity of 4GB per unit. The total number of sticks for each test taken was two. On the other hand, I had the HyperX Fury DDR4 2133Mhz C14 2*4GB RAM sticks. On comparing I found out that the DDR4 RAM was out-performing the DDR3 RAM on the basis of multi-core read and write factors. It provided a very big edge on the overall performance of the computer and is undoubtedly fast enough to make the computer run faster than usual.

RAM to some extent improves the gaming performances on a computer hence, using a multi-core and high speed read and write RAM stick really helps improve the performance of the computer. Considering the price point, as DDR4 RAMs have newly been introduced in the market and the pricing is what is killing it. DDR3 RAM sticks are cheap, but DDR4 RAMs perform better for the price at which it is available for.

Brief summary.

From all the above notes and point that we have all went through it is clear to say that DDR4 RAMs outweigh the performance of the DDR3 ones. With a high clock speed and higher capacity on a single stick, this kind of RAM is surely going to change the way users think computing actually is.

Round four: other points to consider between DDR3 vs DDR4

Compatibility: how does it affect?

The debate on ddr3 vs ddr4 RAM has been up for a long time since its introduction. However, the DDR3 RAMS are suitable only for a specific number of motherboards in the market. The DDR4 RAM is also doing the same. The only difference is that DDR4 is also slowly getting the support of the previous motherboards so that it can provide full potential of itself to the computer and make the computer work faster than usual.

For example, intel’s skylake processors and even the latest coffee lake processors support DDR4 RAMS and there is no way that you can use a DDR3 RAM with this combination.

Pricing and availability

As newly introduced in the market, the DDR4 RAM sticks are available in the market as a sole 16GB memory on a stick. This kind of capacity is available in the market at a higher price than what a DDR3 RAM would cost.

This means that in the market right now, the cost of the DDR3 RAMs is way cheaper than most of the DDR4 RAMs. Thus, investing in a single stick is equivalent to investing in 2 or 3 DDR3 sticks. I would choose the former option as this would provide better security to the computer.

DDR3 vs DDR4 Gaming performances

On the contrary, DDR3 vs DDR4 is the main reason why most of the gamers would prefer the DDR4 RAM sticks over the DDR3 ones. Clock speed is what we users and gamers look for. The DDR4 RAM sticks provide a much higher clock speed which can go up to 4266Mhz when overclocked and thus the performance of the games is boosted with such kind of activities. So in case of gaming performances, DDR4 is the winner.

DDR3 vs DDR4 performance sheet

With certain points to consider like the low voltage input, the module density of the DDR4 RAM makes it stand out of the crowd. In the comparison of DDR3 vs DDR4, DDR4 is the clear winner with higher clock speeds to offer and of its increased stability. These RAM sticks are the future of the whole computing systems.

DDR3 vs DDR4 RAM: future ready!

The DDR4 provides a lot of features by which we can say that these memory sticks are indeed ready for the future. With a refresh algorithm and efficient power input mechanisms with higher clock speed and stability, the DDR4 RAM is ready to launch itself into the market of supercomputers. Thus the debate of DDR3 vs DD4 comes to a halt as DDR4 is simply the future.

Brief summary

It can very well be seen how major an impact the introduction of the DDR4 RAM has made in the market. People are upgrading their systems in order to experience the blazing fast speed of the DDR4 sticks and thus take computing to a different level.

Round five: do you need to upgrade?

Whether you need to upgrade or not depend wholly on how much money you are ready to spend and also the reasons for upgrading.

DDR3 vs DDR4: who wins?

Considering the various DDR3 vs DDR4 comparisons, the various features which the DDR4 RAM provides over the DDR3 RAM stick is way too much. The difference between DDR3 and DDR4are many.

The stability, the power intake, refresh algorithm, module capacity etcetera, all these factors played an important role in the marketing of the new DDR4 RAM sticks. Thus it is very clear that in such type of competition, DDR4 takes the clear win.

But, do you need to upgrade?

Upgrading to a better capacity of RAM is necessary. Considering the fact that the DDR4 RAMs have newly been introduced into the market, the price of the same is super high at the moment. It depends solely upon the computer user what he or she wants. If the performance of the computer doesn’t meet the expectations of the user, then it is advisable to upgrade the PC to a faster one.

Brief summary

RAM is a very important aspect in the building up of a computer. It is that part of the computer without which the computer remains dysfunctional. In DDR3 vs DDR4 RAMs, choosing the best of the both is mandatory.

The tomorrow of RAM

I myself use 2x4GB sticks of DDR3 RAM, and as a high-end gamer, I want performance and better optimization of my memory, so I have been thinking lately to buy the new DDR4 sticks. Are you thinking alike? With all the comparison between the DDR3 vs DDR4­­, we find that the DDR4 is perfectly future ready with all the newest and better features it has to offer to the users. Features like refresh algorithms, stability, minimized power intake, reduction in heat produced, module density etcetera, it proves its worth for the future.

Final verdict: conclusion

It is very important to match up the kind of RAM being used on the computer. Not all RAMs go with each other. Compatibility issues regarding DDR3 vs DDR4 arise and also comes when the frequencies do not match. Thus take your decisions carefully while upgrading to a higher capacity of Ram and making the overall performance of the computer really good to use.
