How much memory frequency is the same DDR3 and DDR4 performance gap

for DDR4 and DDR3 memory, a lot of computer players want to know the DDR4 and DDR3 which is good? Which is worth buying? The following is a test of DDR3 2400MHz memory and DDR4 2400MHz memory, their performance gap is how big. Must the new be stronger than the old ?

Memory testing is more boring, at present in the major hardware, the frequency of memory is often the most easily overlooked, but is the capacity of memory, more than the frequency of memory to be more concerned about a bit higher. Of course, how much memory capacity for the best, is 16G or 8G, or 4G, or to see the user's use of the habit, and now someone is still in the 1g,2g to use, is not a strange thing.

To start with, show the test used two memory, one is the DDR3 memory, the model for Chi qi tridentx 8GB DDR3 2400 (F3-2400C10D-8GTX), the other is the DDR4 memory, the model for the Woo Commando Commando DDR4 2400.

One: DDR4 2400MHz

First Test DDR4 memory.

Woo Commando Commando DDR4 2400 Memory appearance more personality, a kind of military style, as for what, I will not say more, the word too easy to become prohibited words.

The memory specification is 4GB UNB pc4-19200 CL 16-16-16-36, where PC4 represents the desktop DDR4. 19200 is named with bandwidth, 2400*64/8=19200 (Memory bandwidth calculation formula: Bandwidth = frequency * bit width/8), 2400 is the DDR equivalent frequency, 16-16-16-36 is the memory timing.

The weight of this memory strip is then burnt, about 34g.

Select two of the memory in the suite (this set of memory is four) and make up 8 G dual channel platform.

Turn on the XMP option, which is directly 2400MHz. Don't ask me how to open it, why should I? It is a difficult question to answer. The former motherboard specifications are detailed introduction, many motherboards are slightly different.

The latter money to buy is 2400MHz of memory, hard not to be used in 2133 frequency? That might as well buy a 2133MHz of RAM and save money. Of course, someone bought 2400Mhz memory, like not to open XMP, in 2133MHz use, which is also normal.

The hardware situation of the test platform is demonstrated.

Memory display of information.

Take a look at the memory performance score of 11226.

Cpu-z information, memory frequency is 2400MHz, timing is 16-16-16-36

In the AIDA64 software, there is a 2400MHz-frequency scoring display. In the memory benchmark test, the speed of Read, Write, and copy (per MB/s) was 34451, 35150, 30117, respectively.
