This article mainly explains the "computer memory DDR4 and DDR3 what are the differences", the article explains the content is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "what are the differences between computer memory DDR4 and DDR3"!

What is memory?

Memory is one of the most important core components in computer, and memory is the bridge between other hardware and CPU. All programs in the computer are run in memory, so the performance of memory has a great impact on the computer.

Professionally speaking, memory (Memory), also known as internal memory, is composed of memory chips, circuit boards, gold fingers and so on. The function of memory is to temporarily store the operational data in CPU and the data exchanged with external memory such as hard disk. As long as the computer is running, CPU will transfer the data needed for operation to the memory for operation, and when the operation is completed, CPU will transmit the results. The operation of the memory also determines the stable operation of the computer.

What is the difference between DDR4 and DDR3 memory?

DDR4 represents fourth-generation memory, while DDR3 represents third-generation memory, and then there are DDR2 and DDR memory, which means that computer memory is now in its fourth generation. To put it simply, DDR4 is the next-generation version of DDR3 with faster speed and lower power consumption.

The difference between DDR4 and DDR3 in computer memory

First, Goldfinger is different complementary and compatible.

The DDR3 memory gold finger is straight, while the DDR4 memory gold finger becomes curved. This means that DDR4 and DDR3 memory are no longer compatible, while the old platform computer motherboards are designed with straight-line gold finger slots, so they are not compatible with the latest DDR4 memory, and the same new platform motherboards use DDR4 memory slot designs that can no longer use DDR3 or lower versions of memory.

Therefore, in the future installation, the new platform computers do not want to use the DDR3/DDR2 memory on the old computer, the old computer motherboard is not compatible with the latest DDR4, upgrade memory can only still buy DDR3.

Second, different performance

In computer memory, the core factors that determine its performance are frequency and bandwidth, and the memory of different generations is basically divided by these parameters.

The starting frequency of DDR3 memory is 800Hz, the highest frequency is 2133Hz, and the maximum supports 64GB. Our common DDR3 memory is generally 4/8/16GB DDR3 1333 and 1600.

The starting frequency of DDR4 memory reaches 2133Hz, the highest frequency is 3200Hz, and the maximum supports 128GB. At present, the common DDR4 memory is 8GB/16GB/32GB DDR2 2133, 2400amp 3200.

In addition, the bandwidth specification of DDR4 memory is also significantly higher than that of DDR3 memory, and the basic factors that affect memory performance are capacity and frequency, so the performance (speed) of DDR4 memory with the same capacity is much better than that of DDR3.

Third, different power consumption

DDR3 memory uses a standard voltage of 1.5V, while DDR4 memory is reduced to 1.2V, which means lower power consumption.

Thank you for your reading, these are the contents of "what are the differences between computer memory DDR4 and DDR3". After the study of this article, I believe you have a deeper understanding of the difference between computer memory DDR4 and DDR3, and the specific use needs to be verified in practice.
