If you have a notebook or computer, and you want to improve its processing speed, or you are still building a gaming PC and want to keep it running smoothly with the heaviest games, you will certainly need to invest in RAM. And when researching the RAM memory for your computer, you will come across the following question: What is the difference between DDR3 1333 and 1600 RAM and which is the best one to buy?
What is RAM?
Random access memory, or RAM, is one of the most important components of computers, notebooks, tablets, smartphones and game consoles. Without it, doing just about anything on any system would be much slower.
But after all, whatlaugh RAM? In a nutshell, it is an extremely fast type of computer memory, capable of temporarily storing all the information your PC needs at the present time and in the near future.
where your computer carries everything you might need to use soon, so that when you need it, you can read the information quickly. It is quite different from the storage of your system, such as the hard disk (HD or SSD), where the information is stored in the long term.
Perhaps the best analogy for what RAM represents is to think of it as your system's short-term memory. She quick to learn new things, and can load all information about the applications you use so that you can access them quickly. The computer you don't have to go through internal storage every time you want to open a new tab or load a game.
The data that is in the RAM memory can be read from anywhere, almost at the same speed and, because it has a wired connection to your system, there is no real latency in cabling or connection.
However, RAM is not designed to stay focused forever, and is ready to move on to the next task at any time. what is described in computing as "volatile", that is, once the device is turned off, memory forgets everything it has learned.
This makes it perfect for handling the multitude of high-speed tasks that your system performs on a daily basis, but also why we need storage systems like HDs and SSDs to store our information when you turn off the system.
Despite the fact that the expression "clock frequency" is applied more often to the processor, this is the main parameter that determines the speed of the entire computer and its individual components.
The higher the clock frequency, the more data can be transmitted on the bus per second. However, before starting to exchange information, the components again agree with the PM. The processor tells the chipset that it can receive data 3200 times per second (3.2 GHz). RAM – 1600 times per second (1.6 GHz).
And then the chipset determines at what speed to whom what to transmit. Therefore, the overall speed of the computer is determined not by the PM of the processor (as many misconceptions say), but by the PM of the slowest bus.
DDR3 1333 RAM
The 1333 DDR3 RAM operates at a clock frequency of 667 MHz. At the same time, the actual speed of the inverter is 1333 megatransfers per second. That is, 1.3 million signals are transmitted in 1 second. This PM provides high RAM reliability.
In addition, the dies get a little hot, which is very important for systems with little cooling of these components. A 667 MHz PM is enough for office computers and some older games.
DDR3 1600 RAM
The DDR3 1600 RAM operates at a clock frequency of 800 MHz. The actual speed of the unit is 1600 megatransfers per second. This PM provides reasonably high performance. In addition, if the matrix developer takes care of the circuits, the heating will also be negligible. But in some cases, it is necessary to organize the cooler unit separately.
An 800 MHz PM is sufficient for some old games (for 2019, when DDR4 is widely distributed), as well as for complex computing operations, such as archiving or unzipping files.
What is the difference between DDR3 1333 or 1600 mhz memory and which one to choose?
In conclusion, the difference between 1333 and 1600 is in the frequency of the clock, and in the intensity of the heating and consequently in the performance. However, the choice is not as simple as it seems. The fact that, with the release of DDR3, the RAM controller started to be installed directly on the processor. And the maximum compatible PM is determined by that particular chip.
For example, Intel Core processors in the Ivy Bridge family show a marked drop in performance when switching to 1333. This manifests itself in data computing operations (archiving / unzipping) and in games. But AMD Phenom chips, in principle, cannot work with 1600 without unlocking the multiplier.
Therefore, the choice of RAM should be based mainly on compatibility with the planned (or existing) processor. For the Intel Core family, it is better to have high speed right away – the risk of "miscalculation" is minimal. And for AMD, buying a 1600 can be a waste of money. Compare the types of "RAM".
