Comparing DDR3 1333 VS. 1600 RAM

Bandwidth Comparison

As we know, DDR3 1333 and 1600 are two popular types of RAM. So, which one is better?

I decided to compare the bandwidth of both DDR3 1333 and 1600 RAM to see which one is faster.

To do this, we used a tool called “Bandwidth Test.”

The results are as follows:

  • DDR3 1333 RAM: 9.6 GB/s
  • DDR3 1600 RAM: 12.8 GB/s

As you can see, DDR3 1600 RAM is significantly faster than DDR3 1333 RAM. It has a bandwidth of 12.8 GB/s compared to 9.6 GB/s. This means that DDR3 1600 RAM is the better choice if you want the fastest possible performance.

Clock Speed Performance

The below statistics shows the approximate clock speed increase you can expect from DDR3 1333 to 1600 RAM.

  • DDR3 1333: The approximate average increase in clock speed: 3.1%
  • DDR3 1600: The approximate average increase in clock speed: is 4.7%

There is a significant difference in performance between DDR3 1333 and 1600 RAM. If you are looking for the best possible performance, DDR3 1600 is the way to go.

However, if you are on a budget, DDR3 1333 RAM will still significantly increase speed over DDR2 800.

Memory Capacity

DDR3 Memory Capacity

DDR3 1333 and 1600 RAM offer different memory speeds & capacities, with the former having a capacity of 8GB and the latter 12GB.

This means that if you have a lot of data to store or if you need to run resource-intensive programs, the 1600 RAM will be a better choice.

However, if you only need to store basic data and run simple programs, the 1333 RAM will be sufficient. Ultimately, deciding which type of faster RAM depends on your needs and budget.

CAS Latency

The CAS latency of DDR3 1333 and 1600 RAM is 9. This means it takes 9 clock cycles for the first bit of data to be read or written. The second bit takes 8 clock cycles, and so on. So, if you want to transfer 100 MB/s of data, it will take 9 * 100 MB/s = 900 MB/s.

The CAS latency of DDR3 1333 and 1600 RAM is 9. This means it takes 9 clock cycles for the first bit of data to be read or written. The second bit takes 8 clock cycles, and so on. So, when you want to transfer 100 MB/s of data, it will take 9 * 100 MB/s = 900 MB/s.

This is the same for all types of DDR3 RAM, regardless of manufacturer or model. So, if you’re looking for fast memory type, you should look for RAM with lower latency.


There are two main applications for DDR3 1333 and 1600 RAM.

The first is for gaming purposes, as the higher bandwidth provided by these types of RAM can significantly increase performance.

The second is for use in servers or other high-end computing applications where the increased speed and reliability provided by DDR3 1600 RAM can be vital.

How To Know If My RAM Is 1333 Or 1600?


There is no sure-fire way to know whether your RAM is 1333 or 1600 without opening up your computer and checking the specifications. However, there are a few things you can do to try and determine the speed of your RAM.

First, check the documentation with your computer or RAM modules. The speed should be listed somewhere on there.

If you can’t find anything in the documentation, you can try running a system information tool like CPU-Z. This will give you a lot of detailed information about your hardware, including your RAM speed.

Finally, if you still can’t figure it out, you can compare your RAM’s performance to other users’ RAM speed with a tool like Passmark Performance Test. This will give you a good idea of where your RAM falls regarding speed.

Finally, DDR3 1333 or 1600 RAM: Which Is better?

But which one should you get between DDR3 1333 VS. 1600? The answer may not be as simple as you think.

It all depends on what you use your PC for. But after comparing all the facts and features, it may be pretty easy to make the decision!

DDR3 1333 is more than enough if you’re a casual user. It’s faster than DDR2 and more than enough for most tasks.

However, if you’re a power user or a gamer, then DDR3 1600 is the way to go. It’s faster and will give you a noticeable boost in performance.

More Questions & Answer

Is 1333MHz RAM good for DDR3 DIMM?

Distinguished. Yes, that is without a doubt. Compared to high-end 2133Mhz modules, there is only a 5% variation in performance between the two modules. So getting too much RAM is a bit of a waste of money.

Is all DDR3 RAM compatible?

The physical dimensions and shapes of all desktop RAM versions are identical. However, they are not interchangeable. DDR3 RAM cannot be used on a motherboard that only accepts a DDR2 memory Module.

DDR3 is not compatible with DDR4 slots. Each version of RAM has a notch carved into the pins at various positions to prevent confusion.

Can I use two different DDR3 RAM?

Don’t bother. DRAM from various generations can’t be mixed. You can’t even upgrade your DRAM to a different generation if you already have it. Due to your motherboard’s design, it can only handle one kind of RAM.

Can I put 1333mhz RAM in a 1066mhz slot?

Yes, on the face of it. To match the speed of the second RAM stick, your motherboard will automatically reduce the frequency of the 1333 RAM to 1066 MHz.

On the other hand, purchasing modules in pairs is always intelligent. This is because the two modules have been thoroughly tested and found to be compatible.

Can DDR3 1066 Replace 1600?

You may not be able to use 1600 Mhz RAM in a 1066/800 Mhz RAM Slot! DDR3 1066/800 Mhz RAM slots on the motherboard of an old PC may not be compatible with new RAM modules if you’re planning on upgrading.

Can I use 2 different RAM brands?

Does it matter if you mix up the RAM brands? In a nutshell, the answer is yes. Theoretically, you can mix and match RAM on your system regardless of brand, speed, or amount, but this might be troublesome in practice.

You may not even notice a change in performance depending on the configuration and the amount of work you’re doing.

Can I use 2 different RAM brands?

Is it possible to run DDR3 in a DDR3L slot, although the greater voltage and heat might destroy the MB and battery? Nothing will be harmed by it. It has been determined that your CPU can work with standard DDR3 memory.

Is 1066 Mhz RAM good?

Is 1066 Mhz RAM good

Using modern editing tools, 1066 is a little sluggish. Because of the voltage abnormalities and recognition concerns that various modules produce, you’ll want to pick something well-balanced, such as 1866MHz RAM, and purchase the same brand for all sticks.

Can I mix 2gb DDR3 1333 RAM with 4gb DDR3 1600 RAM?

Hey! So, you can technically mix 2GB DDR3 1333 RAM with 4GB DDR3 1600 RAM in your computer, but it’s not the most ideal situation. Mixing RAM of different capacities, speeds, or even from different manufacturers can sometimes lead to stability issues or suboptimal performance.

When you mix RAM sticks with different speeds, the motherboard will typically downclock the faster RAM stick to match the speed of the slower one. In your case, the 4GB DDR3 1600 RAM would run at 1333 MHz, so you wouldn’t get the full speed advantage of the 1600 MHz module.

While it might work without any issues, it’s always best to use RAM sticks that are the same capacity, speed, and from the same manufacturer to ensure maximum compatibility and performance.

However, if you’re in a pinch and need the extra memory, you could give it a shot – just keep in mind that you might not get the best possible performance, and there could be some stability risks.

What is the price difference?

Generally, a 4GB DDR3 1600 RAM module will cost more than a 2GB DDR3 1333 RAM module due to the higher capacity and speed. The difference in price can vary depending on factors such as the brand, quality, and where you buy them from. You might find a price difference of around $10 to $30, but it could be more or less depending on the factors I mentioned.

To get a better idea of the price difference, I recommend checking out online retailers or local computer hardware stores to compare the prices of the RAM modules you’re interested in. Keep in mind that prices can fluctuate, so it’s always a good idea to shop around and look for deals to get the best value for your money.
